One Year Update: 38M FIREd
Well, February 22nd makes it one whole year. I think that's deserving of a top level post, right? Here are screenshots of the Mint Trends, which has every single expense from the past year categorized. I've added comments on each page. Expenses Overview Auto Expenses Food Expenses Home Expenses Utility Expenses Tax Expenses Healthcare Expenses Entertainment Expenses Main takeaways, my total expenses for the year was $37,700, but I'm going to dismiss about $15,000 of that as "one time" expenses from paying off my car and my furniture loan. A more reasonable number for my annual spend is $22,700. With my car payment gone, my highest expense category is Food, averaging $500 per month. This has room for improvement. Healthcare will look artificially low last year because of taking Tax Credits up front. This year I am not and will be paying $325 per month for health insurance. At ~$4000 per year, this puts healthcare at nearly 20% of my total expenses. Nothing else is particularly interesting. That $22,700 figure is a reasonable real-world number for me, but for future planning I'd still inflate that to $25,000 just to have more wiggle room. I may look into traveling this year, which would add some expense. Investments: Vanguard Investments: (All in VTSAX)
Traditional IRA: $299,000 -> $348,000
Roth IRA: $14,500 -> $18,150
Brokerage: $18,400 -> $22,900
Total Rollup: $331,800 -> $389,100. ~17% return
Other LTCG holdings: $145,000 -> $291,000 (other investment accounts and bitcoin) HSA Investment Account: $6000 -> $7400, with another $1700 in the "cash" holdings of the HSA. $9000 cash in Money Market & Checking Account. Finances Going Forward I had earned income last year so I didn't start my Roth Conversion Ladder last year. This year I decided I will be converting the $12,400 standard deduction + $9600 of the first tax bracket for a nice round $22,000 converted. Yes I'll owe a little bit of taxes, but it sets up my Roth with $22k in 5 years which should cover the majority of my expenses. And with $350k currently in tIRA and converting $22,000 per year, I won't be able to chew through it all before actual retirement age. I have about $20k from an old stock purchase plan that unlocks come April, which I will be selling and likely moving over to my money market account to shore up my "cash" holdings. My plan is to not really tap any of my "normal" investment accounts for as long as possible. I've been deferring to selling Bitcoin if I need to move some cash over. Last year I sold 3 bitcoin, one for $9300 in June, and then two at the end of December (for tax year Capital Gains reasons) for $7300 each. These were all LTCG at 0% taxed. AGI for last year is around $35,000. The Living Part: There's all the boring expenses and financial stuff. Now for the ever painful question that my beloved Grandmother loves to ask, "But gosh, what do you do with all of your time! I can't imagine being retired at your age!" Step 1, restful sleep. During my working career I lived off 6 hours of sleep every day. It made for exhausting weekends trying to "make it up." And luckily I'm not a generally stressful person or else it'd have been worse. But now I go to bed when I'm tired, and whenever I naturally wake up, I get up. This can lead to VERY weird hours since I'm often an extreme night owl. But I generally get 9-10 perfect restful uninterrupted dream-filled hours of sleep. I'm betrayed by my "Food Expense" breakdown, but I really am cooking more and eating better. I drink a lot of coffee and water at home and generally try to eat only one meal per day, but sometimes lunch and dinner. I don't normally eat breakfast, just have coffee when I wake up. And did I mention how much less painful it is to go grocery shopping when it's in the middle of the day and everyone's at work. It's so nice. I spend a lot of time on reddit browsing my front page, and I check out the YouTubers I follow that post daily, then check out any of the irregular posters. Depending on how much good stuff there is, this could go on for a few hours. I have a lot of hours playing video games. I tend toward puzzle games or building games (Factorio, Satisfactory) because they scratch that itch in my engineering brain. There are times at night where I'll spend hours on this website: https://www.puzzle-sudoku.com/ and play Sudoku or Nonograms or any of the other puzzle types on the bottom of the page. I'm doing my best to watch every single last show on Netflix. It's a daunting task, though it's surprising how often I drift back toward watching the same smattering of Star Trek: The Next Generation episodes rather than try something new. But I try and take recommendations and work my way through shows. And Podcasts! The joy of joys is when I come across a new-to-me podcast that has a huge backlog. I found a great ST:TNG rewatch podcast that had 108 episodes already done. I spent like 2 months watching the episode of TNG then immediately listening to their podcast about that episode, repeat repeat repeat. I'm currently working my way through The Adventure Zone, I'm on episode 46 of 155 with them. And they keep advertising the other podcasts The McElroys do so I'm sure I'll roll into one of those next. For many people podcasts are background noise, but I'll often just sit on the couch and concentrate on just listening the podcast. Outside of home, I can't wait for the weather to get nicer so I can go on more walks. Being a night owl I like going for walks at night. I live near our city center so I'm within blocks of city hall, the main library branch, and the fountain / park. I jump at any opportunity to hang out with friends. It's just about every weekend that we are getting together to hang out and play board games. Like I mentioned in one of the breakdowns, I've started to play D&D with my buddy and his wife. I'd never played before but he's been DMing for years (but hasn't had a group for 10+ years now). He's glad to be playing again, his wife loves it, and it's super convenient for them to stay home with the 5 month old daughter. (And baby gets to hang out with Uncle Oracle.) I get together with former co-workers every few months to keep in touch with them. One in particular I have a standing every-2-month bar date with. I remind them every so often that if they want to go out to lunch ever to just call me. Personal History Just a quick personal history in closing. I was an automotive engineer working for OEMs and Tier 1 suppliers in the Metro Detroit area. In the 2008 downturn I lost my job and was unemployed for 2 years and ended up getting my house foreclosed in 2010. By the time i got a job in March of 2010 I was basically at $0. I had a tiny amount in an 401k, had about $20,000 in credit card debt from being unemployed. But then I got a very well paying engineering job ($108k annual and eligible for time-and-half overtime). I kept living like I was unemployed, spent as little as possible and saved as much as possible. Through my parents I secured a mortgage on a nice 1 Bed / 1 Bath 900 sq ft condo. I paid off my CC debt in less than a year and kept banking cash and maxing my 401k every year. I heard about bitcoin in early 2013 (from a guildmate in World of Warcraft, believe it or not) and jumped on board. All time bitcoin price chart (log scale) for those unfamiliar with the history. I got in before the first spike to $1000 in December of 2013, and kept buying throughout the downswing in 2014 / 2015. In 2017 I sold 5.6 BTC for a total of $6000 and paid off the last of my student loans and my car, then a few months later I sold 4.25 BTC for $6700 and paid off the last of my condo mortgage. So in May of 2017 I was officially debt free and had a net worth of about $200,000. Then in the fall of 2017 was when bitcoin exploded. I knew I had to take profits here. Every time the price went up 10% I sold another bitcoin. $7500, $9000, $10700, $13000, $15500, $18600. I sold all the way up. I ended up selling about $100,000 in bitcoin that year and I pushed most of it into my Roth IRA and Brokerage accounts. Then I really started thinking about FIRE in early 2018. Started doing the math, tried to see what my expenses would be, and thought I'd give it ago. I've told myself from day 1 that I'd give this trial a solid 2 years. If I don't feel good about it, or the money doesn't seem right, then I'll still only be 40 years old and could (IMO) easily jump right back into an engineering gig. So I targeted early 2019 so I could frontload my 401k for two months, grab the annual bonus, then peace out. TL:DR: 38, FIREd, Money's looking right, Life is feeling right, everything is fine
CryptoDiffer teamHello, everyone!We are glad to meet here:Max Freeman (@maxfreeman4), Project Lead at Epic CashYoga Dude (@Yogadude), PR&Marketing at Epic CashXenolink (@Xenolink), Advisor at Epic Cash Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here! Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here! Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us! CryptoDiffer teamLet`s start from the first introduction question:Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash? Yoga Dude PR&Marketing at Epic Cash Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing. I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially. Xenolink Advisor at Epic Cash Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers! Max Freeman Project Lead at Epic Cash I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level. CryptoDiffer team Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:) Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one? Max Freeman Project Lead at Epic Cash I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly. There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos that explain why we believe we have created something truly special here. Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange. Yoga Dude PR&Marketing at Epic Cash Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility. Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved. Xenolink Advisor at Epic Cash To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry. To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone. CryptoDiffer team Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months? Yoga Dude PR&Marketing at Epic Cash Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content. We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money. You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages Max Freeman Project Lead at Epic Cash Our future development roadmap will be published soon and includes 4 tracks: Usability Mining Core Protocol Ecosystem Development Core Protocol Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020 Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020 Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a Usability GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020 Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020 Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a Mining RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin. Ecosystem Development Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a Xenolink Advisor at Epic Cash From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide. CryptoDiffer team Great, thank you for your answers, we now can move to community questions part! Cryptodiffer Community You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC? Max Freeman Project Lead at Epic Cash The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part. Cryptodiffer Community To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from? Xenolink Advisor at Epic Cash Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project. Cryptodiffer Community Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you! Yoga Dude PR&Marketing at Epic Cash First, I must admit that I am still a huge fan and HODLer of Monero. That said: ✅ our blockchain is MUCH lighter than Monero’s ✅ our transaction processing speed is much faster ✅ our address-less blockchain is more private ✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU Cryptodiffer Community
the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.
Cryptodiffer Community $EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future? Who is Epic Biggest competitors? And what’s makes epic better than competitors? Xenolink Advisor at Epic Cash We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity. Cryptodiffer Community What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Yoga Dude PR&Marketing at Epic Cash Since we are a community project, we have many developers, in addition to the core team. Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks. We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked. Cryptodiffer Community EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges? Xenolink Advisor at Epic Cash In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well. Cryptodiffer Community What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment? Max Freeman Project Lead at Epic Cash Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic. With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash. As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability Cryptodiffer Community Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ? Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors? Max Freeman Project Lead at Epic Cash RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware. Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses. Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware. The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved. Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem? Xenolink Advisor at Epic Cash Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic. Cryptodiffer Community I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto? What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ? Yoga Dude Pr&Marketing at Epic Cash Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential. The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers. The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique Cryptodiffer Community Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI? Yoga Dude PR&Marketing at Epic Cash We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on. Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way. Cryptodiffer Community If you could choose one celebrity to promote Epic-cash, who that would be? Max Freeman Project Lead at Epic Cash I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences. I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today. Epic Cash will have its OWN Celebrities Cryptodiffer Community How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it? Xenolink Advisor at Epic Cash Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin. Cryptodiffer Community what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ? Max Freeman Project Lead at Epic Cash There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make. Cryptodiffer Community Q1 : What are your major goals to archive in the next 3–4 years? Q2 : What are your plans to expand and gain more adoption? Yoga Dude Pr&Marketing at Epic Cash Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁 We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting. Cryptodiffer Community It seems to me that EpicCash will have its first Halving, right? Why a halving so soon? Is a mobile version feasible? Max Freeman Project Lead at Epic Cash Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140. Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining. Cryptodiffer Community What markets will you add after that? Yoga Dude PR&Marketing at Epic Cash Well, we are aiming to have ALL markets Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry) We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages. Epic Cash is More than Money and its for Everyone. Cryptodiffer Community Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins? Max Freeman Project Lead at Epic Cash With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can. Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises. Cryptodiffer Community What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment? Xenolink Advisor at Epic Cash Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash. Cryptodiffer Community
You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well. Cryptodiffer Community Do EPICs in 2020 focus more on research and coding, or on sales and implementation? Yoga Dude PR&Marketing at Epic Cash We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy. In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC. Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters. Everyone with skin in the game gets the benefit of advancing the cause. Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content — https://www.youtube.com/watch?v=XtAVEqKGgqY a challenge from one of our content creators to beat his 21 pull ups and get 100 epics! This has not been claimed yet — people need to step up 🙂 and to help that I will match another 100 Epic Cash to the first person to beat this Cryptodiffer Community I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex? Let’s talk about the economic model, can EpicCash comply with the concept of value reserve? Max Freeman Project Lead at Epic Cash In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader. We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166 Max Freeman Project Lead at Epic Cash Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project. Xenolink Advisor at Epic Cash Would like to Thank the Cryptodiffer Team and the Cryptodiffer community for hosting us and also engaging with us to learn more about Epic. If anyone else has more questions and wants to know more about EPIC , can find us at our telegram channel at https://t.me/EpicCash . Yoga Dude Pr&Marketing at Epic Cash Thank you, CryptoDiffer Team, and this wonderful Community!!! Cryptodiffer TEAM Thank you everyone for taking your time and asking great questions Thank you for your time, it was an insightful session Spread the love
Author:Gamals Ahmed, CoinEx Business Ambassador ABSTRACT A Blockchain is a continuously growing record, called blocks, which are linked and secured using cryptography such as hashing. Each block contains a hash pointer as a link to the previous block, a timestamp and transaction data. Filecoin is a decentralized storage network that turns cloud storage into an algorithmic market. The market runs on a blockchain with a native protocol token (also called Filecoin), which miners earn by providing storage to clients. The first section of report is demonstrate the filecoin which is a decentralized storage system used to encrypt files that we need to share it through blockchain platform. The second section is explain briefly blockchain Proof of Concept (POC) which is a process of locate whether a Blockchain project idea can be feasible in a real-world situation, need of proof of concept and blockchain proof of concept stages. 1.Introduction Filecoin is a protocol token whose blockchain runs on a novel proof, called Proof-of-Space time, where blocks are created by miners that are storing data. Filecoin protocol provides a data storage and retrieval service via a network of independent storage providers that does not rely on a single coordinator, where: (1) clients pay to store and retrieve data, (2) Storage Miners earn tokens by offering storage (3) Retrieval Miners earn tokens by serving data. Filecoin is a decentralized storage network that turns cloud storage into an algorithmic market. The market runs on a blockchain with a native protocol token (also called Filecoin”), which miners earn by providing storage to clients. Conversely, clients spend Filecoin hiring miners to store or distribute data. As with Bitcoin, Filecoin miners compete to mine blocks with sizable rewards. Filecoin mining power is proportional to active storage, which directly provides a useful service to clients (unlike Bitcoin mining, whose usefulness is limited to maintaining blockchain consensus). This creates a powerful incentive for miners to amass as much storage as they can, and rent it out to clients. The protocol weaves these amassed resources into a self-healing storage network that anybody in the world can rely on. The network achieves robustness by replicating and dispersing content, while automatically detecting and repairing replica failures. Clients can select replication parameters to protect against different threat models. The protocol’s cloud storage network also provides security, as content is encrypted end-to-end at the client, while storage providers do not have access to decryption keys. Filecoin works as an incentive layer on top of IPFS , which can provide storage infrastructure for any data. It is especially useful for decentralizing data, building and running distributed applications, and implementing smart contracts . Filecoin based on IPFS proposes a completely decentralized distributed storage network where customers and storage miners request services and submit orders to the storage and retrieval markets. And the miner provides a service to view matching quotes to initiate a transaction. The protocol guarantees the integrity of data storage by copying proofs and space-time certificates. The Filecoin protocol writes the order book, token transactions, and integrity challenge response records to the blockchain. 1.1 Blockchain Blockchain is a characteristic data structure formed by combining data blocks in a chain order inchronological order, and cryptographically guarantees decentralized, non-tamperable, unforgeable distributed shared ledger system. Figure 1 Blockchain Structure 1.2 Elementary Components in Filecoin The Filecoin protocol builds upon four novel components :
Decentralized Storage Network (DSN): We provide an abstraction for network of independent storage providers to offer storage and retrieval services.
Novel Proofs-of-Storage: We present two novel Proofs-of-Storage,(1) Proof-of Replication allows storage providers to prove that data has been replicated to its own uniquely dedicated physical storage. Enforcing unique physical copies enables a verifier to check that a prover is not deduplicating multiple copies of the data into the same storage space, (2) Proof-of-Space time allows storage providers to prove they have stored some data throughout a specified amount of time.
Verifiable Markets: We model storage requests and retrieval requests as orders in two decentralized verifiable markets operated by the Filecoin network. Verifiable markets ensure that payments are performed when a service has been correctly provided. We present the Storage Market and the Retrieval Market where miners and clients can respectively submit storage and retrieval orders.
Useful Proof-of-Work: We show how to construct a useful Proof-of-Work based on Proof-of Space time that can be used in consensus protocols. Miners do not need to spend wasteful computation to mine blocks, but instead must store data in the network .
1.3 Filecoin: Lifecycle of a File In this section we mentioned the lifecycle for file in Filecoin, as follow:
Put: Clients send information about the file, storage duration, and a small amount of Filecoin to the Storage Market as a bid. Simultaneously, Miners submit asks, competing to offer low cost storage. Deals are made in the Storage Market, on the blockchain.
Send: The Client then sends the file to the Miner, and the Miner adds the file to a sector. The sectors are cryptographically sealed, with verification sent to the blockchain.
Manage: Miners continuously prove they are storing all sectors they agreed to store. The client’s payment is released in installments. Additional currency is minted over time and awarded to Miners as a block reward, proportional to the storage they provide.
Request: A Client requests a file with some payment in Filecoin to the Retrieval Market (off chain); the first Miner to send the file is paid. Eventually, the contract expires and the storage is once again free.
Figure 2 Filecoin Lifecycle of a File 1.4 Filecoin is Built with IPFS The Interplanetary File System (IPFS) is a next-generation protocol to make the Web faster, safer, decentralized, and permanent. Since the initial IPFS release in January 2015, it has gained strong traction in a variety of industries and organizations. Today, IPFS is a foundational technology for many applications in the blockchain industry. Over 5 billion files have been added to IPFS, spanning scientific data and papers, genetic research, video distribution & streaming, 3D modeling, legal documents, entire blockchains and their transactions, video games, and more. IPFS and Filecoin are complementary protocols, and the adoption of the underlying IPFS protocol is a leading indicator of market demand for a faster, safer, decentralized storage service . Some IPFS Users Figure(3) IPFS users 1.5 IPFS Open Source Community The IPFS Project is a large community of open source contributors driven to decentralize the web. The community is made up of thousands of developers and users who have been working together for several years, building valuable and widely used software tools. The same seasoned core developers of IPFS are also leading the design and development of Filecoin. The IPFS team has experience building ambitious sotware projects and coordinating thriving developer communities. A significant portion of the IPFS community plans to join the Filecoin network, building tools and applications on this new, exciting platform [ 7]. 2. PoC PROJECTS: 2.1 What is PoC? PoC is abbreviate of Project of Concept which is a process of determining whether a Block-chain project idea can be feasible in a real-world situation. This process is necessary to verify that the idea will function as envisioned. The best part about proof of concept blockchain meaning is that it will help you to get a clear idea of what you are doing before you even get started. Furthermore, the proof of concept in the blockchain niche isn’t for exploring the marketplace for ideas only. Moreover, you won’t determine the best way to start the production process. Instead, you’ll only work on your possible blockchain solution option and see whether it’s capable of being a reality or not. Developing a blockchain proof of concept would require an investment of time, money and resources. In reality, you’d need to get your hands on supporting technologies or even the physical components needed to get the perfect plan. Going through the process is necessary for enterprises to see whether their idea is visible before using all production level equipment for it. According to a recent Gartner survey, 66% of CIOs think that blockchain is here to disrupt the existing marketplaces. And many will spend more than $10 million on the experimentation of the technology. So, if you were confused with what is proof of concept blockchain, now you know just what it is . PoC is used to demonstrate the feasibility and practical potential of any blockchain project in any field such as Energy, Communication, Services, Insurance and Healthcare. A PoC can either be a prototype without any supporting code or any MVP (Minimum Viable Product) with bare feature set. A PoC is a prototype that is used for internal organization who can have a better understanding of a particular project. 2.3 Why Companies Need a Proof of Concept? Usually, the blockchain proof of concept is awfully popular among the startups in the market. However, proof of concept in blockchain can also be a great tool for the Enterprises as well. Mainly there are three points for needing it.
Test out the blockchain project before going for mass production.
Identify possible pain points that can make the project not useful.
Save an enormous amount of time and money.
Although anyone who comes up with a blockchain project idea will think that it will work, however, proof of concept in blockchain will test out your idea to ensure that you get the best version out of it, which will save up a lot of time and money in the process. Another major reason for you to use proof of concept for blockchain is to ensure that all the stakeholders love your idea and would be interested in investing in it. Whether you are just adding up a new type of feature in the existing blockchain solution or developing it from scratch blockchain proof of concept would let you take the fastest route possible. This relatively gives a different edge in the proof of concept blockchain meaning . 2.4 Proof of Concept Phases Its explain as follows: Figure (4) explains the steps of blockchain PoC Step-1: Finding the Proper Blockchain Application Sectors That Adds Value Let’s start with the first step of the theoretical build-up stage. Many of you don’t really know which application sectors are great for blockchain Proof of concept . That’s why we are outlining some major application sector where you can use your solution. These are: 1.Finance Let’s start with the financing sector. This sector is relatively popular among the blockchain community. Furthermore, there are many projects already that cover this sector and offer a lucrative solution for major issues. So, in that sense, this sector is quite competitive in case of blockchain PoC development. 2. Medical The medical sector is another major blockchain application sector at present. There are count-less scenarios where blockchain can truly shine. Hospitals have to deal with a lot of falsifying reports and counterfeit drugs. 3. Asset Management Maintaining asset in these times are relatively hard due to all the bad players in the market. Simple paper-based record keeping isn’t enough now. Moreover, due to political and other reasons, ownership management is at risk of becoming a corrupted sector. 4. Government Many governmental institutions are falling behind in the race of digitization. Moreover, every citizen needs a better infrastructure which will give them the security they need. In reality, the government sector is unable to reserve the citizen rights properly. 5. Identity Identity management is a big hassle when it comes to enterprises. Furthermore, many often impersonate other people’s identity and commit serious crimes. Even in trade financer, many companies have to deal with fake companies and fake documents. 6. IoT Internet of things is a wonderful sector for proof of concept in blockchain development. Furthermore, this sector is responsible for linking all your smart applications together. Moreover, the device to device connection in a secured platform is necessary. 7. Payments The payments sector is another awesome application point for your enterprise-grade solution. The blockchain system is more than capable of handling payments, and many of it also offer micro payments. Furthermore, it takes a really small amount of time to send money compared to the traditional banking system. Not to mention the reduction of fees in overseas payment. 8. Supply Chain Big enterprise needs to have their eyes and ears in every step of the supply chain process. Furthermore, any minor errors could end up in a million dollars of loss. Obviously, you would not want that. Tracking where the raw materials are coming from and whether your products are truly authentic or not is one of the major pain points. 9. Insurance The insurance industry is facing some serious problems regarding insurance claims and document authentication. Also, the enormous amount of paperwork that every single employee has to fill out is overly dreadful. Detecting fraud, managing all the documents in a secure environment is tough. So, if you introduce a blockchain framework that can solve all these issues would be a huge factor. However, the competition in this marketplace is a bit high; still, with proper blockchain proof of concept, it should be a great opportunity. Step-2: Defining the Product In the second stage of the theoretical build-up, you would need to think your blockchain Proof of concept just like any other product. Furthermore, you need to have a solid plan along with full support from all stakeholders. PoC Feature Requirements Define all the features that your enterprise blockchain solution needs. After deciding your blockchain application, you would probably have some idea on what features to add up. Step-3: Investigating the Technology After you’ve come up with the solid idea of what features to include and how to focus the road map, you would need to hand them off to the engineering team. Therefore, your team will then research the technology based on your requirements and come up with the best plat-form to develop it on.
Advice to make a successful Proof of Concept As we knew, a proof of concept is a project, and like any project it must be clearly defined. That means breaking down the process into these four steps in order to can manage it better.
Focus on a Specific Business Issue If you want to make the blockchain PoC framework a success, then you have to start with focusing your real-life problems. At the beginning of the theoretical build-up stage when you are looking for a popular sector of deployment, look for a specific issue. Furthermore, any problem that your idea can fix would be a big plus from the consumers’ end. Many blockchain proof of concept only focuses on the capabilities of the technology only. However, they just don’t resolve any new issues or even old issues.
Take Small Steps, Avoid Scope Creeps Another major thing that the enterprises face is the scope creeps. While choosing what features you might need for the blockchain proof of concept many go for too much from the start. However, making a flashier entrance in the market won’t mean 100% success. Further-more, get the ones that you can truly deliver, not the ones you aren’t capable of.
Connect All Ideas and Control Them You won’t be the only one coming up with all the ideas. As you already know you’d need to get yourself a good team that will back you up and helps you come up with a compact solution. However, not every single member of your team would agree with the same idea. Furthermore, they have different ideas and vision regarding the blockchain development too.
Construct a Thorough Plan Another hurdle in the way of proper proof of concept blockchain is the misinterpretation of the blockchain implementation challenges. Obviously, blockchain implementation isn’t an easy task. At the first stage, it might have many flaws that would end up in possible failure scenarios.
Test A Million Times After getting the design done, you’d need to go into the testing phase. However, the problem is many seem to enroll the MVP before properly testing it, which end up in failure. So, test out the MVP a lot of time before making it accessible to the end-users.
Collaborate With Other Parties Collaborating with other enterprises could help to take down the overall costing of the block-chain proof of concept. Furthermore, if you are a small to medium level enterprise than collaborating with other parties could help out with the production costing. It will solely depend on the feature or the type of blockchain PoC framework you want to work on.
The Right Amount of Staff The right amount of stuff is always necessary to pull off a blockchain proof of concept project. Furthermore, you would need to recruit staffs that have blockchain skills or have an intellectual concept of the technology. Get the necessary amount of stuff with blockchain skill set to perfect the Blockchain Proof of Concept..
3. Conclusion This report explain a distributed storage scheme based on blockchain technology( Filecoin), and introduces the system design in detail in first part , we have studied about blockchain technology related for Filecoin(decentralized storage network), Filecoin, a highly-anticipated decentralized storage network (under development), announced that there will be more delays before its Mainnet can be officially launched. Created by Protocol Labs, Filecoin has been developed using the InterPlanetary File System (IPFS), an established peer to peer data storage network. The Filecoin software will allow users to trade storage space in an open and decentralized market place.In the second part we mentioned a proof of concept (PoC), The Blockchain Proof of Concept is a demonstration to verify that certain concepts or theories have the potential for real-world application. PoC represents the evidence demonstrating that a project or product is feasible and worthy enough to justify the expenses needed to support and develop it. REFERENCES  Juan Benet.

Pi Network! This golden project is an opportunity.
What is Pi Network?
Pi Network is a virtual currency that can only be mined or mined on a phone, but does not consume device resources like other free mining applications. Previously Pi Network could include mining applications such as Electroneum (ETN), but this application consumes your device resources to decode the algorithm (Electroneum uses cryptonight algorithm). With Pi Network, when you dig coins will feel the device does not heat up. In addition, you can also turn off the application or turn off the network and still be able to mine coins every 24 hours.
Pi Network is still in BETA. The project is still in progress which means that there will still be errors and some details of the project are still changing. While many cryptocurrency projects start from pure theory, Pi Network seeks to balance theory with design and people-centered (or experiment with real people to best meet their needs). ). The project appreciates your patience and welcomes your input as we work together to develop products that best meet community needs. Pi does NOT give you free money. This is a long-term project whose success depends on the common contribution of its members. Pi helps people capture economic value, which is held by banks, technology giants (e.g. Facebook, Amazon) and other intermediaries. Pi depends on the contribution of the members. Therefore Pi NetWork is not suitable for those who want to make money quickly.
2. Is Pi Network scam?
Pi is not a hoax. This is an attempt by a group of Stanford University alumni to spread the cryptocurrency to more people. Pi Network's core team is led by two Stanford PhDs and one Stanford MBA, all of which help build the blockchain community at Stanford. There is no guarantee that the project will succeed. However, Pi Network will work hard to make common dreams a reality, while upholding the highest standards of transparency. You can learn more about Pi's core team on the app, or simply by typing these people 's names into the Google search page: - Nicolas Kokkalis: Head of Technology - Department Chengdiao Fan: Vincent - McPhillip Product Manager: Community Manager 📷 https://preview.redd.it/rozcs5h1p4351.png?width=710&format=png&auto=webp&s=c5952d879514c33e643958aab8d5ca5ae382ba41
3. How to make money with Pi Network?
How to exploit Pi Pi Network does not call you to invest or do anything. Your job is very simple, you just need to have a phone, download the Pi Network app and create an account, press the Start button daily and the PI digging will take place even if your computer is not connected to the internet . You also do not need to open the active application. Pi does not affect your phone performance, does not drain your battery or use your network data. To start earning Pi, check the app every 24 hours and press the lightning button to start mining. You can increase your hourly Pi rate by inviting friends and family to join the community. After 3 days of exploitation, you can increase your income even more by building your security circle, which contributes to the overall security of the network. And remember, veterans of the network have a higher rate of extraction than the members who come after them. Why are veteran members exploiting more? Pi's goal is to become a widely distributed and widely used electronic currency in the world. To achieve that goal, Pi encourages members to contribute early to ensure the success of the project (eg network protection and development). To reflect the importance of early contributions, the rate of extraction decreases as more people join the network. At this point, the base mining rate will be halved every time the number of active users increases by 10 times. This ratio will be reduced to zero when the network reaches a certain number of users (for example, 10 million or 100 million). At the time, like Bitcoin, miners would continue to receive rewards with transaction fees, rather than being rewarded with new coins. What is the Pi Network security circle? The security circle is a group of 3-5 trusted people built by each Pi member, to prevent fraudulent transactions. While cryptocurrencies like Bitcoin secure their ledgers by forcing mining companies to burn energy (proof of work), Pi still guarantees its ledger when members of the network prove trust with each other. Pi contributors guarantee each other by building up security groups of 3-5 members whom they deem reliable. The security circle should include people you trust not to make fraudulent transactions. The cyber security circles form a global trust chart to determine who can trust to conduct transactions on the Pi ledger. https://preview.redd.it/rmekfcizo4351.png?width=710&format=png&auto=webp&s=92a054233ec9c1844b32c24b0a06d0a47e9302b1
4. What is the Pi price?
Pi is worth approximately 0 dollars / euro. Yes! If the price is $ 0, then we dig PI do? Also you wonder when PIs will be valuable? While everyone thinks that PIs are not valuable and do not participate, just like when BITCOIN 2008 had no value. If you are a PI holder PI holders have two options to convert PIs into cash: - Buy goods and services directly with your Pi. Pi Network is building a peer-to-peer market where members can directly spend Pi to buy goods and services. Pi Network aims to start a bank transfer test in its application immediately after Q42019. - Exchange Pi for cash on cryptocurrency exchanges. Pi will be able to be traded during Phase 3 of the project (such as when launching the Mainnet). At that time, exchanges may choose to list Pi. At this point, Pi's core team focuses on implementing the right technical roadmap to reach phase 3. (I still remember in 2015, in MMO communities, competing to receive free coins called Raiblocks (XRB) by typing captcha, each type of such a lot of XRB, it can be said that the day that XRB has no price value, almost 0. Later in early 2018 when Raiblocks changed its name to NANO project, the peak of 1 NANO coin reached 34 USD, sweeping away the dream of millionaires of MMO people, because at XRB, they sell very cheaply for each other. You can refer to the NANO price chart below) https://preview.redd.it/r8rll5eyo4351.png?width=710&format=png&auto=webp&s=235368ab0b53c5e1b09c2c88bd13e345ae26eaae
5. Download the Pi Network application

You cannot withdraw the Pi. You will be able to withdraw Pi or exchange Pi for other currencies during Phase 3 of the project, when Pi switches to a completely decentralized blockchain. Phase 1 of Project Pi is on March 14, 2019 (Pi Day). In Stage 1, your balance is being recorded to wait for the day Pi reaches the mainnet (Phase 3). The transfer or withdrawal of Pi is restricted until the mainnet launch, to prevent fraudulent actions, such as clone users to dig Pi, then transfer Pi to another account and legalize the process. verify your account and use that nefarious Pi number.
8. Should you dig Pi on multiple phones?
No, you SHOULD NOT dig PI on many devices. Pi Network adheres to a strict rule, meaning that only one account can be used per person. Pi Network uses a multi-pronged strategy to ensure that fake accounts cannot exploit Pi First, the Pi network uses Google Recaptcha v3 to know which devices are operated by humans or robots. (This technology is completely invisible to most users, because they are real people, but robots can see the captcha if the google algorithm captures them.) Over time, Pi Network is developing a machine learning algorithm based on actual user exploitation behavior to predict bots. Second, the Pi consensus algorithm (security circle) makes it easy to detect fake accounts. The fake account will not have enough real people to link to them through the security circle. Thus fake accounts will have less linkage with the rest of the network. This anomaly is easy to detect with computer algorithms. Finally, when Pi enters Stage 3 and 4 - Mainnet, only authenticated accounts can exist. Buy
The Sun Exchange raises $3M for crypto driven solar power in Africa
Read more on WordPress https://ift.tt/2AaMmq6 https://ift.tt/2XLfCfV South Africa based renewable energy startup Sun Exchange has raised $3 million to close its Series A funding round totaling $4 million. The company operates a peer-to-peer, crypto enabled business that allows individuals anywhere in the world to invest in solar infrastructure in Africa. How’s that all work? “You as an individual are selling electricity to a school in South Africa, via a solar panel you bought through the Sun Exchange,” explained Abe Cambridge — the startup’s founder and CEO. “Our platform meters the electricity production of your solar panel. Arranges for the purchasing of that electricity with your chosen energy consumer, collects that money and then returns it to your Sun Exchange wallet.” It costs roughly $5 a panel to get in and transactions occur in South African Rand or Bitcoin. “The reason why we chose Bitcoin is we needed one universal payment system that enables micro transactions down to a millionth of a U.S. cent,” Cambridge told TechCrunch on a call. He co-founded the Cape Town headquartered startup in 2015 to advance renewable energy infrastructure in Africa. “I realized the opportunity for solar was enormous, not just for South Africa, but for the whole of the African continent,” said Cambridge. “What was required was a new mechanism to get Africa solar powered.” Sub-Saharan Africa has a population of roughly 1 billion people across a massive landmass and only about half of that population has access to electricity, according to the International Energy Agency. Recently, Sun Exchange’s main market South Africa — which boasts some of the best infrastructure in the region — has suffered from blackouts and power outages. Image Credits: Sun Exchange Sun Exchange has 17,000 members in 162 countries who have invested in solar power projects for schools, businesses and organizations throughout South Africa, according to company data. The $3 million — which closed Sun Exchange’s $4 million Series A — came from the Africa Renewable Power Fund of London’s ARCH Emerging Markets Partners. With the capital the startup plans to enter new markets. “We’re going to expand into other Sub-Saharan African countries. We’ve got some clear opportunities on our roadmap,” Cambridge said, referencing Nigeria as one of the markets Sun Exchange has researched. There are several well-funded solar energy startups operating in Africa’s top economic and tech hubs, such as Kenya and Nigeria. In East Africa, M-Kopa sells solar hardware kits to households on credit then allows installment payments via mobile phone using M-Pesa mobile money. The venture is is backed by $161 million from investors including Steve Case and Richard Branson. In Nigeria, Rensource shifted from a residential hardware model to building solar-powered micro utilities for large markets and other commercial structures. Nigeria’s Rensource raises $20M to power African markets by solar Sun Exchange operates as an asset free model and operates differently than companies that install or manufacture solar panels. “We’re completely supplier agnostic. We are approached by solar installers who operate on the African continent. And then we partner with the best ones,” said Cambridge — who presented the startup’s model at TechCrunch Startup Battlefield in Berlin in 2017. “We’re the marketplace that connects together the user of the solar panel to the owner of the solar panel to the installer of the solar panel.” Abe Cambridge, Image Credits: TechCrunch Sun Exchange generates revenues by earning margins on sales of solar panels and fees on purchases and kilowatt hours generated, according to Cambridge. In addition to expanding in Africa, the startup looks to expand in the medium to long-term to Latin America and Southeast Asia. “Those are also places that would really benefit from from solar energy, from the speed in which it could be deployed and the environmental improvements that going solar leads to,” said Cambridge.

Bitcoin faucets are websites or applications that offer you a small amount of bitcoin as a reward for making easy tasks. Depending on the selected faucet, users can earn coins for completing various tasks, such as viewing certain websites, watching ads, entering a captcha, or playing a game. by StealthEX At the beginning of the cryptocurrency’s existence, when the stakes were not so high, the creators of faucets gave 5 bitcoins for each claim — back then it was their way to promote digital money among newcomers. Now faucets operate with much smaller amounts and give out some part of the Bitcoin, which is measured in Satoshi(named after the creator of Bitcoin). Satoshi is the smallest possible fractional number of Bitcoin — one BTC is equal to 100 million Satoshi. If you have ever left a water tap not completely closed, you probably noticed that water was dripping into it, and if you put a bowl under it, sooner or later it will be filled. Even though one-time payments on faucets are scanty, many advise not to neglect the opportunity to earn on them, because, with the right approach, faucets can bring a tangible profit with a minimum of effort. There are plenty of sites offering free bitcoins. Unfortunately, most of them are not trustworthy, do not live long, or are simply overflowed with annoying flashing ads. However, there are some that work for many years, used by thousands of users and considered reliable. Here is the list of them:
This faucet is probably the most well-known one. It was created in 2013 on the territory of the British Virgin Islands. Payouts are not fixed and vary for each claim. You can get cryptocurrency every hour, and for each claim you get from 0.00000030 to 0.03 BTC. In addition to the faucet, Freebitcoin allows you to earn in other ways — save interest on your deposit, play the lottery, invite new users via referral links. It supports several withdrawal methods: you can set up automatic withdrawal every Sunday, slow withdrawal every 6–24 hours, or use the fastest instant withdrawal that takes 15 minutes. The last one, of course, has the highest fee.
Founded in 2015, the Moon Bitcoin has a certain user base and is considered by many to be one of the best faucets in existence. There are many appealing bonus offers. For example, the site gives you a reward for consistency — if you enter a captcha at least once every day, you will accumulate a bonus +1% to earnings daily. Like most other faucets, Moon Bitcoin offers a bonus for bringing new users. Earned funds are instantly transferred to the linked Coinpot wallet. The minimum withdrawal amount is 10,000 Satoshi if you agree to pay the fee. Or wait until it’s going to be over 50,000 Satoshi on your account and withdrawal money for free. It is worth saying that Coinpot has its own bonus program. For example, for one captcha entry, you get 3 Coinpot tokens that can also be converted to cryptocurrency. There are also Moon faucets for Litecoin, Dash, Bitcoin Cash and DogeCoin. All payments are concentrated in one Coinpot account.
Bonus Bitcoin is one of the oldest services and is considered one of the best bitcoin faucets. You can request a new portion of free coins every 15 minutes, getting an average of 10 Satoshi per claim. You can also gain more coins completing tasks in the offers and surveys section. Users who regularly stay active for a number of days receive an additional 5% of their daily rewards. The site also gives 50% of all fees of users you invited using referral links. Bonus Bitcoin accounts are also connected to Coinpot, a micro-earnings wallet that accumulates your payouts. The site also provides the opportunity to earn Litecoin and Dogecoin.
This is one more faucet associated with Coinpot wallet. Bitfun started its work in January 2017. In addition to the faucet itself, which allows you to request free Satoshi every 3 minutes, the site has a large number of browser games of various genres. Progress in these games gives you additional earnings. You can also earn coins by completing offers. As with Bonus Bitcoin, the user receives 50% of the fees of their referrals.
The service was launched in 2018 and has become known as one of the best free bitcoin generators. There are several ways to claim Satoshi. In addition to the faucet, you can also earn bitcoins by watching videos, clicking on ads, and playing browser games. Here you can make claims once every 12 hours and get a certain number of Coins to your account. Coins are the inner currency of this service, 10000 Coins worth 1$. It converted to Satoshi at the time of withdrawal. Rewards can be collected at FaucetHub, another web wallet for micropayments, in this case, the withdrawal limit is 35,000 Coins. For amounts over 100,000 Coins, withdrawals can be made directly to your bitcoin wallet. Or you can keep Coins at the site and earn 5% interest. Users can earn a loyalty bonus, by claiming rewards every day. Bringing another user via referral link gives you 25% of their claims and 10% of their offer earnings.
PentaFaucet is one of the oldest and most stable bitcoin faucets today. The main difference from similar websites is that the site uses double protection: captcha and anti-bot. You can collect from 5 to 25 Satoshi every 5 minutes. A reasonable amount of advertising and a simple interface make working with the faucet comfortable. The faucet does not allow you to earn money from games, surveys, and other sponsorship services. In addition to the main method, it offers only a referral program, giving 10% from earnings of each new user. Earned Satoshi are instantly transferred to the FaucetHub wallet. You can withdraw your funds from FaucetHub to your bitcoin wallet once a week on Sundays.
FireFaucet is a multi-currency automatic faucet, perhaps the best of its kind. This resource allows you to earn 9 cryptocurrencies at the same time, as well as instantly withdraw the accumulated funds to the Faucet Hub. The Auto Claim function allows for collecting currency automatically. You can change the number of currencies to get and the time between collections. FireFaucet affords many different ways to earn money: in addition to the faucet itself, there are also offers, a referral system that gives 20% from newcomer’s income, and browser mining. FireFaucet also has its own unique level system: getting XP for various actions on the site and raising their level, users receive a reward in Satoshi. As a pleasant addition, FireFaucet has a nice-looking design and does not use pop-up ads.
This bitcoin faucet does not require registration. All you need is the public address of your BTC wallet. Users can claim Satoshi every hour, getting from 5 to 1200 each time. At the moment DailyFreeBits is using the FaucetHub wallet we are already familiar with. The resource offers a referral reward. By inviting new users to the website, you can regularly receive 10% of their earnings. These are probably the best bitcoin faucets at this point. Do not expect that you will earn loads of money just using faucets, but it is with no doubt an interesting and easy way to get a certain portion of free Satoshi and learn how the cryptocurrency and various wallets work. Always be careful and study every site that is claimed to be a Bitcoin faucet with some scepticism. Always be critical of your choice and read reviews.

We Just Hit $500k NW! 25 & 26 Years Old. $156k DINK Income. Here's Our Story.
Hi guys. I've been a subscriber and lurker here for over 5 years and one of my favorite things to read are the "how you got to where you are" stories. I made this post once I hit $300k, but my new wife and I just hit the $500k milestone together and we thought it would be worthwhile to share our story. We hate lack of transparency and ambiguity, so we'll be as open and honest as possible. We tried to include everything that we would want to know as if we were reading someone else's post. Feel free to ask us any questions. There is a TLDR at the bottom of this post. You probably want to read that first to see if you're interested before investing your time in conquering this wall of text. Also, you can skip the wall of text below about our childhood/college/relationship stuff if you're just interested in the "numbers". I just wanted to include this background to provide context.
Age: I'm 26 and discovered FIRE via Mr. Money Mustache in 2012 at the age of 19. It blew my mind and instantly resonated with me. My wife is 25 and she found FIRE through me. We've been dating since we were 17. When I first discovered FIRE she didn't really buy into the idea until a couple years later when she started her first corporate internship and had her "Office Space" existential crisis. So she became a true believer around age 21.
Childhood: I come from a rural, solidly middle-class background. I owe all my success with my academics, career, and finances to my parents. My dad is a mechanic and my mom is a nurse. Both are very frugal and they passed that down to me. They are natural savers and maxed out their 401(k)s and IRAs every year on their modest incomes. They also pushed upon me the value of education. They had high academic expectations for me and I was always at the top of the class because of it. My wife comes from a lower-middle class background. Her parents immigrated from Mexico right before she was born and they run the local Mexican restaurant in our childhood hometown. Due to their business, they've always worked very long hours and had highly variable income over the years depending on how the restaurant was doing. They definitely aren't natural savers and have almost nothing saved for retirement. They work extremely hard, but believe the American Dream means spending your hard-earned money on nice things (cars and such). They also didn't push the value of education as hard as my parents did, but my wife didn't need it because she was way more self-driven than I ever was. They are great parents, but we don't always see eye-to-eye when it comes to our outlooks on life. Nonetheless, they are good people and raised my wife to be an amazing person.
College Years: We both graduated in the top 2% of our high school class and had good test scores and extracurriculars. We both went to the same top public in-state university. Since we were both in-state, it was already a great value, but I received a full-ride academic scholarship from the university and my wife also received considerable scholarships and grants. My parents saved about $20k in a 529 plan for me to go to college. But since I got a full-ride, they gave me $10k as a college graduation gift and used the other $10k to pay for my sister's college. This was the only "windfall" that I've ever received (other than my scholarships). My wife's parents didn't save anything for her college, but they did help pay a couple thousand dollars of expenses in the first year. After that, my wife paid 100% of the costs on her own with no parental assistance and no student loans (funded by a couple grants/scholarships, part-time campus jobs, and an engineering co-op). I graduated in 2015 with a degree in business and my wife graduated in 2017 with a degree in industrial engineering. While in college we both worked hard academically and maintained good GPAs, but most importantly, we got fantastic work experience through internships and co-ops. This helped us gain experience, build our resumes, and get great starting jobs right our of college. It also helped us pay the bills and save a considerable amount of money while we were in college. We both graduated with no student debt and a considerable amount of money ($60k for me and $20k for her). Those numbers probably seem a little crazy, but you can read my previous post for the details of how we managed to save so much money in college. Long story short, I worked 3 jobs (dorm RA and two high-paying part-time internships) and had almost no expenses due to my full-ride scholarship. My wife worked 2 jobs (part-time on-campus job and a high-paying engineering co-op) and had very low expenses. Because we found FIRE so early, we both also managed to max out our Roth IRAs for a few years while in college.
Relationship: The most important part of each our our lives is each other. We went to high school and college together. We've been dating for 9 years and we just got married in May of this year (since this is a financial sub, I know you're wondering....we spent $9.9k on our wedding). We've lived together for 4 years and bought a small condo in the city 2 years ago. Although our incomes aren't identical, we split everything 50/50. She is dead-set on the path to FIRE now, although it took her a few years to really understand the "why". Now she is more frugal and more extreme than me!
Income: I graduated college at age 22. My first full-time job was making $55k. Now I make $86k at age 26. I'm a typical "financial analyst/project manager" for a Fortune 500 company. It's a pretty low-stress 40 hour per week job with 10-20% travel to support clients. If I had never negotiated twice for more money, I'd be at ~$68k right now instead of $86k. I'm still at the same company that I started at and not necessarily looking to change anytime soon. I really love my team, boss, work-life balance, and the work that I do. We also live less than 1 mile from my office, so I walk to work everyday. My wife graduated college at age 23. Her first full-time job was making $53k. Now she makes $70k at age 25. She is a also a typical "financial analyst/engineer" for a different Fortune 500 company. Her job is slightly higher stress and probably averages 45 hours per week with no travel. She's also still at the same company that she started at and definitely not looking to change anytime soon. She has great benefits and has a strong reputation as a rising star in the organization.
Home: We live in a MCOL city in the south. Our rent for the first two years out of college was $1,500 per month ($750 each) for a 1-bedroom apartment in the nicest area of the city (and walkable to my office). About 2 years ago we bought a 435 square-foot, 1-bedroom condo in the nicest part of the city for ~$125k. We did this as a way to maximize the efficiency of our monthly budget - not necessarily as a long-term investment. We plan on living here for at least another 5 years (we want to have kids in our early 30s), then keep it as an investment property. We've been living here for 2 years and we absolutely love it. It seems too good to be true.
Food/Dining/Groceries: $200 (Shop at Aldi and Kroger, always buy generic, eat out less than once per month, cook every meal, and bring lunches to work everyday).
Car Insurance: $171 (USAA for 2 cars: 2005 Scion xB with 120k miles and 2012 Honda Civic with 90k miles).
Gas: $40 (We both have short commutes).
Vacation: $200 (Carries over if we don't use it).
Fun Money: $200 (Our catch-all category if it doesn't fit in a category above. Things like video games, concerts, home decorations, new clothes, Amazon Prime, Netflix, HBO Now, extra vacation money if we go over our $200 budget, etc.).
Debt: Our only debt is our $97k mortgage.
Net Worth: $502,934
Roth IRAs: $90,541
Taxable Investments: $106,188
Property: $47,978 ($36,300 in Home Equity + Our Vehicles).
Savings Rate: Currently our savings rate for 2019 is sitting at 81%. Since starting our full-time jobs, our savings rate has always been between above 65%. It has steadily increased as our incomes have increased.
FIRE Goal: $1.5-2.0 million. Right now our expenses are very low, but we expect them to rise in about 5 years when we have kids and move into a larger house in a good school district. We hope to hit this amount by age 35-40, but we'll just have to wait and see what happens. Right now my FIRE spreadsheet says we'll hit $1.5 million when we're 32 and $2.0 million when we're 34. With the 4% withdrawal rule this equates to $60k-80k of withdrawals per year. We currently live comfortably on less than $25k per year, so we definitely are leaving a lot of buffer.
Post-FIRE Aspirations: I've always dreamed of being a high school US History teacher and tennis coach. I'd like to at least try it once to see how I like it. Since I'm FIRE I could easily quit If I don't like it. I've also always dreamed of being some kind of not-for-profit financial adviser for the "Average Joe" American. More of a "financial coach" where I could help people everyday with the basics (budgeting, index investing, etc.). Never selling any products. Just sharing my story and trying to inspire people to make positive changes in their lives. My wife is likely to continue her corporate career for a while - even once we're comfortably FIRE. It's hard for me to understand that, but she derives a lot of worth and happiness from her career. But most of all, we want to be great parents. One of the biggest drivers of our FIRE goal is to be very close to FIRE by the time we have kids in our early-mid 30s. We just want to be a part of our child's life every step of the way and just be "there" for them. And of course we have a ton of "bucket list" items that we'd love to try out (thru-hike the Appalachian Trail, thru-hike the John Muir Trail, build a camper-van and road trip to all the National Parks again, etc.).
Our Advantages: Amazing parents who helped to put good heads on our shoulders; frugal upbringings; being born in the U-S-of-A; large college scholarships; having a life partner with whom we share each other's values and aggressive FIRE goals; the 2013-2019 bull market; supportive friends; learning about FIRE at such a young age; and many, many more things.
General Habits Worth Mentioning:
We've maxed out our 401(k)s, Roth IRAs, and HSAs every year since starting our full-time jobs, plus invested the excess in a taxable account.
We've never invested in bitcoin or anything like that, just boring old Vanguard index funds. Vanguard is showing our personal rate of return since 2013 as 11.76%, which is only slightly better than the S&P 500 during that time.
We love to travel. We go on 3-5 trips per year to National Parks, European cities, etc. that we fund via "credit card travel hacking" courtesy of churning.
Unlike a lot of people on this sub, we've introduced the idea of FIRE to most of our close friends. Our parents and siblings also know our FIRE goals, but we set clear boundaries. My family is very understanding (my parents are FIREing next year at age 54). Her family still thinks we're crazy. We're pretty open about our journey and try to help others if they are interested. Because of this, our 15-20 closest friends are all into FIRE as well. We hang out with friends 2-3 nights per week, but instead of "going out for drinks" (we don't drink alcohol anyways...) we go over to each other's homes for home-cooked dinners and board games. I say this because we have a good social network, but don't have to spend a ton to maintain it. Having a like-minded SO and like-minded friends have been two of the most important contributors to our happiness and high savings rate.
Saving this much and maintaining a 70%+ savings rate hasn't been "hard" for us. We don't have to try very hard to accomplish these goals - it's just who we are. We are natural savers. Saving EXCITES us. We don't feel like we make any sacrifices in our life to meet these goals. We buy everything that we want...we just find that we don't "want" a lot of the typical things that other people "want" (luxury cars, eating out, 5-star hotels, brand-name clothes, $30k wedding, huge home, etc.)....And the best part is that each of us found another person whose values are so closely aligned to our own.
TLDR: Two married DINKs hit $500k net worth at age 25 and 26. We both had frugal upbringings. We both got scholarships/grants to top in-state university. We both worked 2-3 jobs every week while attending college to pay for living expenses and saved the rest. I got degree in business. She got a degree in industrial engineering. We graduated with no debt and $80k saved up. I made $55k/year at my first full-time and she made $53k/year at hers. 4.5 years after graduating I currently make $86k and 2.5 years after graduating she makes $70k. Our monthly budget is $1,822/month. Our savings rate is 81%. We have been dating for 9 years, living together for 4 years, and we got married in May.

This is a followup of my older post about the history of payment channel mechanisms. The "modern" payment channel system is Lightning Network, which uses bidirectional indefinite-lifetime channels, using HTLCs to trustlessly route through the network. However, at least one other payment channel mechanism was developed at roughly the same time as Lightning, and there are also further proposals that are intended to replace the core payment channel mechanism in use by Lightning. Now, in principle, the "magic" of Lightning lies in combining two ingredients:
Offchain updateable systems.
HTLCs to implement atomic cross-system swaps.
We can replace the exact mechanism implementing an offchain updateable system. Secondly we can replace the use of HTLCs with another atomic cross-system swap, which is what we would do when we eventually switch to payment points and scalars from payment hashes and preimages. So let's clarify what I'll be discussing here:
I will be discussing mechanisms for the offchain updateable system, which are generally called "payment channel mechanisms". The exact contracts that can be transported across such systems, such as HTLCs, the Scriptless-Script point-based variant, and Discrete Log Contracts, will have to wait another post.
Payment channel mechanisms are designed to be trust-minimized. They might not achieve this design goal (consider the broken Satoshi sequence numbers, or the pre-SegWit Spilman, which I still class as "payment channel mechanism"), but mechanisms which invoke trust in one participant or other as inherent parts of their design are not true payment channels. Such constructions might be of interest, but I will not discuss them here.
Now I might use "we" here to refer to what "we" did to the design of Bitcoin, but it is only because "we" are all Satoshi, except for Craig Steven Wright. So, let's present the other payment channel mechanisms. But first, a digression.
Digression: the new nSequence and OP_CHECKSEQUENCEVERIFY
The new relative-timelock semantics of nSequence. Last time we used nSequence, we had the unfortunate problem that it would be easy to rip off people by offering a higher miner fee for older state where we own more funds, then convince the other side of the channel to give us goods in exchange for a new state with tiny miner fees, then publish both the old state and the new state, then taunt the miners with "so which state is gonna earn you more fees huh huh huh?". This problem, originally failed by Satoshi, was such a massive facepalm that, in honor of miners doing the economically-rational thing in the face of developer and user demands when given a non-final nSequence, we decided to use nSequence as a flag for the opt-in replace-by-fee. Basically, under opt-in replace-by-fee, if a transaction had an nSequence that was not 0xFFFFFFFF or 0xFFFFFFFE, then it was opt-in RBF (BIP125). Because you'd totally abuse nSequence to bribe miners in order to steal money from your bartender, especially if your bartender is not a werebear. Of course, using a 4-byte field for a one-bit flag (to opt-in to RBF or not) was a massive waste of space, so when people started proposing relative locktimes, the nSequence field was repurposed. Basically, in Bitcoin as of the time of this writing (early 2020) if nSequence is less than 0x80000000 it can be interpreted as a relative timelock. I'll spare you the details here, BIP68 has them, but basically nSequence can indicate (much like nLockTime) either a "real world" relative lock time (i.e. the output must have been confirmed for X seconds before it can be spent using a transaction with a non-zero nSequence) or the actual real world, which is measured in blocks (i.e. the output must have been confirmed for N blocks before it can be spent using a transaction with a non-zero nSequence). Of course, this is the Bitcoin universe and "seconds" is a merely human delusion, so we will use blocks exclusively. And similarly to OP_CHECKLOCKTIMEVERIFY, we also added OP_CHECKSEQUENCEVERIFY in BIP112. This ensures that the nSequence field is a relative-locktime (i.e. less than 0x80000000) and that it is the specified type (block-based or seconds-based) and that it is equal or higher to the specified minimum relative locktime. It is important to mention the new, modern meaning of nSequence, because it is central to many of the modern payment channel mechanisms, including Lightning Poon-Dryja. Lessons learned?
Poetic justice is a thing. Go go new nSequence!
Decker-Wattenhofer "Duplex Micropayment Channels"
Mechanisms-within-mechanisms for a punishment-free bidirectional indefinite-lifetime payment channel. The Decker-Wattenhofer paper was published in 2015, but the Poon-Dryja "Lightning Network" paper was published in 2016. However, the Decker-Wattenhofer paper mentions the Lightning mechanism, specifically mentioning the need to store every old revocation key (i.e. the problem I mentioned last time that was solved using RustyReddit shachains). Maybe Poon-Dryja presented the Lightning Network before making a final published paper in 2016, or something. Either that or cdecker is the Bitcoin time traveler. It's a little hard to get an online copy now, but as of late 2019 this seems to work: copy Now the interesting bit is that Decker-Wattenhofer achieves its goals by combining multiple mechanisms that are, by themselves, workable payment channel mechanisms already, except each has some massive drawbacks. By combining them, we can minimize the drawbacks. So let's go through the individual pieces.
Indefinite-lifetime Spilman channels
As mentioned before, Spilman channels have the drawback that they have a limited lifetime: the lock time indicated in the backoff transaction or backoff branch of the script. However, instead of an absolute lock time, we can use a relative locktime. In order to do so, we use a "kickoff" transaction, between the backoff transaction and the funding transaction. Our opening ritual goes this way, between you and our gender-neutral bartender-bancho werebear:
First, you compute the txid for the funding transaction and the kickoff transaction. The funding transaction takes some of your funds and puts it into a 2-of-2 between you and the bartender, and the kickoff is a 1-input 1-output transaction that spends the funding transaction and outputs to another 2-of-2 between you and the bartender.
Then, you generate the backoff transaction, which spends the kickoff transaction and returns all the funds to you. The backoff has a non-zero nSequence, indicating a delay of a number of blocks agreed between you, which is a security/convenience tradeoff parameter
You sign the backoff transaction, then send it to the bartender.
The bartender signs the backoff, and gives back the fully-signed transaction to you.
You sign the kickoff transaction, then send it to the bartender.
The bartender signs the kickoff, and gives it back to you fully signed.
You sign and broadcast the funding transaction, and both of you wait for the funding transaction to be deeply confirmed.
The above setup assumes you're using SegWit, because transaction malleability fix. At any time, either you or the bartender can broadcast the kickoff transaction, and once that is done, this indicates closure of the channel. You do this if you have drunk enough alcoholic beverages, or the bartender could do this when he or she is closing the bar. Now, to get your drinks, you do:
Sign a transaction spending the kickoff, and adding more funds to the bartender, to buy a drink. This transaction is not encumbered with an nSequence.
Hand the signed transaction to the bartender, who provides you with your next drink.
The channel is closed by publishing the kickoff transaction. Both of you have a fully-signed copy of the kickoff, so either of you can initiate the close. On closure (publication and confirmation of the kickoff transaction), there are two cases:
You fail to pick up any chicks at the bar (I prefer female humans of optimum reproductive age myself rather than nestling birds, but hey, you do you) so you didn't actually spend for drinks at all. In this case, the bartender is not holding any transactions that can spend the kickoff transaction. You wait for the agreed-upon delay after the kickoff is confirmed, and then publish the backoff transaction and get back all the funds that you didn't spend.
You spend all your money on chicks and end up having to be kicked into a cab to get back to your domicile, because even juvenile birds can out-drink you, you pushover. The bartender then uses the latest transaction you gave (the one that gives the most money to him or her --- it would be foolish of him or her to use an earlier version with less money!), signs it, and broadcasts it to get his or her share of the money from the kickoff transaction.
Pro: Number of updates is limited only by the amount of money you have in the "payer" side of the channel.
Pro: no lifetime limit. You can keep the channel open indefinitely if you don't transact over it.
Pro: The delay can be very small.
Decrementing nSequence channels
Enforcing order by reducing relative locktimes. I believe this to be novel to the Decker-Wattenhofer mechanism, though I might be missing some predecessor. This again uses the new relative-locktime meaning of nSequence. As such, it also uses a kickoff transaction like the above indefinite-lifetime Spilman channel. Set up is very similar to the setup of the above indefinite-lifetime Spilman channel, except that because this is bidirectional, we can actually have both sides put money into the initial starting backoff transaction. We also rename the "backoff" transaction to "state" transaction. Basically, the state transaction indicates how the money in the channel is divided up between the two participants. The "backoff" we sign during the funding ritual is now the first state transaction. Both sides keep track of the current state transaction (which is initialized to the first state transaction on channel establishment). Finally, the starting nSequence of the first state transaction is very large (usually in the dozens or low hundreds of blocks). Suppose one participant wants to pay the other. The ritual done is then:
A new version of the current state transaction is created with more money in the payee side.
This new version has nSequence that is one block lower than the current state transaction (in practice it should be a few blocks lower, not just one, because sometimes miners find blocks in quick succession).
Both sides exchange signatures for the new state transaction.
Both sides set the new state transaction as the current state transaction that will be the basis for the next payment.
When the channel is closed by publication of the kickoff transaction, then the transaction with the lowest nSequence becomes valid earlier than the other state transactions. This is enough to enforce that the most recent state transaction (the one with the lowest nSequence, and thus the first to become valid) is published.
Pro: indefinite lifetime, at least if no updates are done.
Pro: it shows that life is not without a sense of irony. The original design for nSequence replacement required an incrementing nSequence using the original Satoshi's Vision interpretation of nSequence (which doesn't work). But this channel mechanism instead uses a decrementing nSequence using the new Bitcoin Core interpretation of nSequence as a relative timelock (which does, in fact, work).
Con: Number of updates is limited by the starting maximum nSequence delay. Increasing this delay increases the encumbrance if the channel is closed without any activity, but reducing this delay reduces the number of payments in either direction you can use before you have to close the channel and recreate it. For example, let's have a maximum of 144 blocks of delay. Each update, we decrement the nSequence by 4, because that handles up to the very rare case where up to 3 blocks arrive in very close succession to each other. That only gives us 36 updates for a worst-case of one day of delay, a very bad tradeoff.
Con: You can only be safely offline for a number of blocks equal to the "step", but the maximum delay you may incur is the product of the step times the number of updates you want to make. So you want a small step (because you don't want your worst-case lock time to be large) but you want a big step (because you want to still be safe even if you go offline for a long time).
Combining the ingredients of the Decker-Wattenhofer Duplex Micropayment Channels concoction. Of note is that we can "chain" these mechanisms together in such a way that we strengthen their strengths while covering their weaknesses. A note is that both the indefinite-lifetime nSequence Spilman variant, and the above decrementing nSequence mechanism, both have "kickoff" transactions. However, when we chain the two mechanisms together, it turns out that the final transaction of one mechanism also serves as the kickoff of the next mechanism in the chain. So for example, let's chain two of those decrementing nSequence channels together. Let's make them 144 blocks maximum delay each, and decrement in units of 4 blocks, so each of the chained mechanisms can do 37 updates each. We start up a new channel with the following transactions:
A funding transaction paying to a 2-of-2, confirmed deeply onchain. All other transactions are offchain until closure.
A kickoff transaction spending the funding transaction output, paying to a 2-of-2.
A "stage 1" decrementing nSequence state transaction, spending the kickoff, with current nSequence 144, paying to a 2-of-2.
A "stage 2" decrementing nSequence state transaction, spending the stage 1, with current nSequence 144, paying to the initial state of the channel.
When we update this channel, we first update the "stage 2" state transaction, replacing it with an nSequence lower by 4 blocks. So after one update our transactions are:
A funding transaction paying to a 2-of-2, confirmed deeply onchain. All other transactions are offchain until closure.
A kickoff transaction spending the funding transaction output, paying to a 2-of-2.
A "stage 1" decrementing nSequence state transaction, spending the kickoff, with current nSequence 144, paying to a 2-of-2.
A "stage 2" decrementing nSequence state transaction, spending the stage 1, with current nSequence 140, paying to the second state of the channel.
The first 3 transactions are the same, only the last one is replaced with a state transaction with lower `nSequence. Things become interesting when we reach the "stage 2" having nSequence 0. On the next update, we create a new "stage 1", with an nSequence that is 4 lower, and "reset" the "stage 2" back to an nSequence of 144. This is safe because even though we have a "stage 2" with shorter nSequence, that stage 2 spends a stage 1 with an nSequence of 144, and the stage 1 with nSequence of 140 would beat it to the blockchain first. This results in us having, not 36 + 36 updates, but instead 36 * 36 updates (1296 updates). 1296 updates is still kinda piddling, but that's much better than just a single-stage decrementing nSequence channel. The number of stages can be extended indefinitely, and your only drawback would be the amount of blockchain space you'd spend for a unilateral close. Mutual cooperative closes can always shortcut the entire stack of staged transactions and cut it to a single mutual cooperative close transaction. But that's not all! You might be wondering about the term "duplex" in the name "Duplex Micropayment Channels". That's because the last decrementing nSequence stage does not hold the money of the participants directly. Instead, the last stage holds two indefinite-lifetime Spilman channels. As you might remember, Spilman channels are unidirectional, so the two Spilman channels represent both directions of the channel. Thus, duplex. Let's go back to you and your favorite werebear bartender. If you were using a Decker-Wattenhofer Duplex Micropayment Channel, you'd have several stages of decrementing nSequence, terminated in two Spilman channels, a you-to-bartender channel and a bartender-to-you channel. Suppose that, while drinking, the bartender offers you a rebate on each drink if you do some particular service for him or her. Let us not discuss what service this is and leave it to your imagination. So you pay for a drink, decide you want to get the rebate, and perform a service that the bartender finds enjoyable. So you transfer some funds on the you-to-bartender direction, and then later the bartender transfers some funds in the bartender-to-you channel after greatly enjoying your service. Suppose you now exhaust the you-to-bartender direction. However, you note that the rebates you've earned are enough to buy a few more drinks. What you do instead is to update the staged decrementing nSequence mechanisms, and recreate the two Spilman directions such that the you-to-bartender direction contains all your current funds and the bartender-to-you direction contains all the bartender's funds. With this, you are now able to spend even the money you earned from rebates. At the same time, even if the staged decrementing nSequence mechanisms only have a few hundred thousand updates, you can still extend the practical number of updates as long as you don't have to reset the Spilman channels too often.
Pro: chaining allows more possible updates!
Pro: no "toxic waste"! That is, old backups of your channel state database won't cause you to lose funds automatically.
Con: unilateral closes have long lock times, due to the chaining of decrementing-nSequence mechanisms.
Con: unilateral closes put a lot of transactions onchain, due to the chaining of multiple nested mechanisms.
Con: HTLCs are affected by the total nSequence delay needed by the mechanism. This is because HTLCs have an absolute timelock in their contract, and this can only be enforced onchain. However, the existence of nSequence delays means that absolute timelocks need to trigger unilateral closes several blocks before the absolute timelock, by the nSequence total delta of all the stacked mechanisms. In Poon-Dryja you can safely keep a channel open until just before the absolute timelock expires.
Con: It's not clear to me if the cancellable HTLCs used by Lightning can be hosted by Spilman channels. The HTLCs used in Lightning are "cancellable" because of a nifty ability of every offchain update mechanism: every contract has an additional clause "... or if every signer of the offchain update mechanism agrees, we can ignore this contract and place its funds wherever we agree on". This is not a degradation of security since the HTLCs in a channel are between the two users of the channel, so both of them need to agree anyway in order to accept such a cancellation. This ability is used to propagate forwarding failures back to the payer: instead of waiting for the HTLCs to time out, the node just says to the sender "between you and me, this HTLC won't propagate anyway, because 'insert some reason here', so let's just put the money in it back to you". However, this seems unsafe with Spilman channels, as a cancelled HTLC will still be available on older states of the Spilman channel, and potentially claimable by the payee end up until the timelock. Removing the Spilman channels at the end would remove this issue, but now you are limited to a few hundred thousand updates even with lots of decrementing-nSequence layers.
Burchert-Decker-Wattenhofer Channel Factories
Because you like channels so much, you put channels inside channels so you could pay while you pay. I N C E P T I O N The Decker-Wattenhofer Duplex Micropayment Channels introduced the possibility of nesting a channel mechanism inside another channel mechanism. For example, it suggests nesting a decrementing-nSequence mechanism inside another decrementing-nSequence mechanism, and having as well an unlimited-lifetime Spilman channel at the end. In the Decker-Wattenhofer case, it is used to support the weakness of one mechanism with the strength of another mechanism. One thing to note is that while the unlimited-lifetime Spilman channel variant used is inherently two-participant (there is one payer and one payee), the decrementing-nSequence channel mechanism can be multiparticipant. Another thing of note is that nothing prevents one mechanism from hosting just one inner mechanism, just as it is perfectly fine for a Lightning Network channel to have multiple HTLCs in-flight, plus the money in your side, plus the money in the counterparty's side. As these are "just" Bitcoin-enforceable contracts, there is no fundamental difference between an HTLC, and a payment channel mechanism. Thus the most basic idea of the Burchert-Decker-Wattenhofer Channel Factories paper is simply that we can have a multiparticipant update mechanism host multiple two-party update mechanisms. The outer multiparticipant update mechanism is called a "channel factory" while the inner two-party update mechanisms are called "channels". The exact mechanism used in the Burchert-Decker-Wattenhofer paper uses several decrementing-nSequence mechanisms to implement the factory, and Decker-Wattenhofer Duplex Micropayment Channels to implement the channel layer. However, as noted before, there is no fundamental difference between a Poon-Dryja channel and an HTLC. So it is in fact possible to have chained Decker-Wattenhofer decrementing-nSequence mechanisms to implement the factory level, while the channels are simply Poon-Dryja channels.
So this concludes for now an alternative mechanism to the classic Poon-Dryja that Lightning uses. The tradeoffs are significantly different between Decker-Wattenhofer vs Poon-Dryja:
Decker-Wattenhofer: No toxic waste: old data stolen from you, or which you inadvertently use, is not going to lose all your funds.
Decker-Wattenhofer: Multiple participants in a single offchain mechanism, enabling things like Channel Factories.
Poon-Dryja: Doesn't have ridiculously long lock times in the unilateral close case.
Poon-Dryja: Supports HTLCs for trustless forwarding (not clear if Decker-Wattenhofer fully supports this without sacrificing the duplexed indefinite-lifetime Spilman channels at the end).
