Recently I decided to change all my professional and personal plans. I left my job. I left my friends and family. I left my country. All for Bitcoin. Here is why.
Discovering my core values I was born and raised in an upper-middle income family in Mexico City under catholic values but turned agnostic as I grew older. I kept the values that made sense, such as the importance of charity and giving back, and threw away the ones that were outdated, such as the focus on guilt as a motivator of change. As a kid, I remember how conflicting it was to see other kids working in the streets, starving, drugged, and abused. I couldn’t understand why they couldn’t focus on their education the way I did. That planted a seed in my spirit that still grows. Seeing in economics hope As a teenager, I entered the rabbit hole of economics with hope. Economics seemed to be this mystical force capable of solving the world’s biggest problems: poverty, corruption, global warming, and many more. I knew that the way we were doing economics was wrong and I wanted to change that. Just think about the horrible things that have been done under the name of communism, such as the Cambodian genocide, or how the United States, the crown jewel of capitalism, makes of fundamental rights, such as healthcare and education, profitable businesses instead of granting everyone equal access to them. While studying my undergrad, I quickly fell out of love with the idealistic idea of economics as an almighty force that can conquer all evils. I saw how economics was often used as an excuse to force simplistic representations of culture and society into complex problems. I never understood how that approach of thinking about problems in a vacuum could be useful. Understanding the power of financial services Later in my life, while working as a consultant for McKinsey, I finally understood the importance of financial institutions. They decide who should do business and have access to goods and services and who shouldn’t. And financial institutions don’t grant everyone that right. It was clear to me that that was a problem that needed fixing. That’s why I devoted so much time studying this industry back then. I came to Berkeley to Business School more out of inertia than out of will. I was sponsored by McKinsey and had an offer to go back. I didn’t know exactly what to do with the experience, but I knew I wanted to keep exploring financial services. During my MBA, I heard about Bitcoin in a serious academic environment for the first time and it immediately caught my interest. Via Berkeley-SkyDeck, a startup school, I heard about lastbit (lasbit.io) for the first time. I read everything I could about the project and about the founder, this cool, heavy-metal lover, who wanted to change the world with the disruptive power of Bitcoin. I could see myself in him. I had to meet him. After failing to meet him in person at an event, I just cold emailed him praying for him to answer. He did. That’s how I came in contact with Prashanth for the first time, this impressive 25-year-old genius who managed to get Charlie Lee on board of his project with little more than a prototype. There’s a reason why he managed to do this. Today Bitcoin is almost impossible to spend. With Prashanth’s his solution, anyone will be able to swipe a card or tap their phone and pay with Bitcoin instantly anywhere where they are able to pay with their credit card today. Something not so long ago possible only in bitcoiners’ dreams. Through Prashanth I finally understood what Bitcoin really is. It blew my mind. Unveiling the real meaning of Bitcoin Bitcoin is not an investment asset, it’s the possibility of a new social contract. Bitcoin is a decentralized, transparent, and auditable network to store and transmit value to which everyone in the world can have access to. This presents a real opportunity to redefine money, which today is inherently centralized, first by central banks, and then by financial institutions. The centralization of money has at least three critical problems that Bitcoin solves. First, there is a macroeconomic problem that has to do with monetary policy and that today with the COVID-19 economic crisis is more relevant than ever. Money is supposed to be a reflection of real economic value, but some central banks print money arbitrarily. Bitcoin’s monetary supply is limited by design. Second, centralized financial services are discriminatory and don’t allow free access to everyone. Bitcoin is universal and free. This means that for the first time in human history, everyone will be able to participate in the global economy. And participation is the pillar of democracy. Third, central authorities control private information. The recent attacks to high profile account on Twitter illustrate how vulnerable private information is when stored in centralized networks. Bitcoin allows people to have full ownership and control of their personal and financial information, protecting both their identity and their wealth. As such, Bitcoin emerged in front of my eyes as a way to instrument basic democratic principles in a way in which everyone can have equal representation. Money as we know it will soon be a thing of the past because money as we know it not fair nor egalitarian and now people can choose. I had to quit McKinsey. I had to leave Mexico. I had to stay with lastbit. I had to give this project my all.
Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it! (If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?) (Pedants: I mostly elide over lockin times) Briefly, Taproot is that neat new thing that gets us:
Multisignatures (n-of-n, k-of-n) that are just 1 signature (1-of-1) in length!! (MuSig/Schnorr)
Better privacy!! If all contract participants can agree, just use a multisignature. If there is a dispute, show the contract publicly and have the Bitcoin network resolve it (Taproot/MAST).
Activation lets devs work get back to work on the even newer stuff like!!!
Cross-input signature aggregation!! (transaction with multiple inputs can have a single signature for all inputs) --- needs Schnorr, but some more work needed to ensure that the interactions with SCRIPT are okay.
Block validation - Schnorr signatures for all taproot spends in a block can be validated in a single operation instead of for each transaction!! Speed up validation and maybe we can actually afford to increase block sizes (maybe)!!
SIGHASH_ANYPREVOUT - you know, for Decker-Russell-Osuntokun ("eltoo") magic!!!
OP_CHECKTEMPLATEVERIFY - vaulty vaults without requiring storing signatures, just transaction details!!
So yes, let's activate taproot!
The SegWit Wars
The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions. So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!
bit - A field in the block header, the nVersion, has a number of bits. By setting a particular bit, the miner making the block indicates that it has upgraded its software to support a particular soft fork. The bit parameter for a BIP9 activation is which bit in this nVersion is used to indicate that the miner has upgraded software for a particular soft fork.
timeout - a time limit, expressed as an end date. If this timeout is reached without sufficient number of miners signaling that they upgraded, then the activation fails and Bitcoin Core goes back to the drawing board.
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two. A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this. So, first some simple questions and their answers:
Why not just set a day when everyone starts imposing the new rules of the softfork?
This was done classically (in the days when Satoshi was still among us). But this might argued to put too much power to developers, since there would be no way to reject an upgrade without possible bad consequences. For example, developers might package an upgrade that the users do not want, together with vital security bugfixes. Either you live without vital security bugfixes and hire some other developers to fix it for you (which can be difficult, presumably the best developers are already the ones working on the codebase) or you get the vital security bugfixes and implicitly support the upgrade you might not want.
Sure, you could fork the code yourself (the ultimate threat in the FOSS world) and hire another set of developers who aren't assholes to do the dreary maintenance work of fixing security bugs, but Bitcoin needs strong bug-for-bug compatibility so everyone should really congregate around a single codebase.
Basically: even the devs do not want this power, because they fear being coerced into putting "upgrades" that are detrimental to users. Satoshi got a pass because nobody knew who he was and how to coerce him.
Suppose the threshold were lower, like 51%. If so, after activation, somebody can disrupt the Bitcoin network by creating a transaction that is valid under the pre-softfork rules, but are invalid under the post-softfork rules. Upgraded nodes would reject it, but 49% of miners would accept it and include it in a block (which makes the block invalid) And then the same 49% would accept the invalid block and build on top of that, possibly creating a short chain of doomed invalid blocks that confirm an invalid spend. This can confuse SPV wallets, who might see multiple confirmations of a transaction and accept the funds, but later find that in fact it is invalid under the now-activated softfork rules.
Thus, a very high threshold was imposed. 95% is considered safe. 50% is definitely not safe. Due to variance in the mining process, 80% could also be potentially unsafe (i.e. 80% of blocks signaling might have a good chance of coming from only 60% of miners), so a threshold of 95% was considered "safe enough for Bitcoin work".
Why have a timeout that disables the upgrade?
Before BIP9, what was used was either flag day or BIP34. BIP34 had no flag day of activation or a bit, instead, it was just a 95% threshold to signal an nVersion value greater than a specific value. Actually, it was two thresholds: at 75%, blocks with the new nVersion would have the new softfork rules imposed, but at 95% blocks with the old nVersion would be rejected (and only the new blocks, with the new softfork rules, were accepted). For one, between 75% and 95%, there was a situation where the softfork was only "partially imposed", only blocks signaling the new rules would actually have those rules, but blocks with the old rules were still valid. This was fine for BIP34, which only added rules for miners with negligible use for non-miners.
The reasons miners signalled support was because they felt they were being pressured to signal support. So they signalled support, with plans to actually upgrade later, but because of the widespread signalling, the new BIP66 version locked in before upgrade plans were finished. Thus, the timeout that disables the upgrade was added in BIP9 to allow miners an escape hatch.
The Great Battles of the SegWit Wars
SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain). So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%. Thus were the Great SegWit Wars started.
BIP9 Feature Hostage
If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage. You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever. With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you. This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.
ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Overt ASICBoost - Manipulates the unused bits in nVersion to reduce power consumption in mining.
Covert ASICBoost - Manipulates the order of transactions in the block to reduce power consumption in mining.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected. Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway. Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost! But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage). Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit. Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!
UASF: BIP148 and BIP8
When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit. Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit. This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core. Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout). BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled. This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9. Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.
BIP91, SegWit2X, and The Aftermath
BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community. One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym. The text of the NYA was basically:
Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91. Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit. Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X). This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists. Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout) So let's take a look at Modern Softfork Activation!
Modern Softfork Activation
This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
First have a 12-month BIP9 (fail at timeout).
If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation. The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.
PSA: Being Resilient to Upgrades
Software is very birttle. Anyone who has been using software for a long time has experienced something like this:
You hear a new version of your favorite software has a nice new feature.
Excited, you install the new version.
You find that the new version has subtle incompatibilities with your current workflow.
You are sad and downgrade to the older version.
You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system. And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk. Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations. So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist. Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems. When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well). This recommendation is from gmaxwell on IRC, by the way.

Someone posted on here a few days ago asking about forex and forex trading in Kenya, I have gone through the responses and clearly, most people don’t have an idea. It is 3am in the morning and am in a good mood so let me make this post. This will be a comprehensive and lengthy post so grab a pen and paper and sit down. We’ll be here a while. FIRST OF ALL, who am I..? I am a forex trader, in Nairobi, Kenya..i have been actively involved in forex since I found out about it in Feb 2016 when I somehow ended up in a wealth creation seminar (lol) in pride inn Westlands, the one close to Mpaka Rd. Luckily for me, it was not one of those AIM global meetings or I’d be on Facebook selling God knows what those guys sell. I did not take it seriously till August of the same year and I have been active ever since. I don’t teach, mentor or sell a course or signals, I trade my own money. I am also posting from a throwaway account because I don’t want KRA on my ass. What the fuck is forex and forex trading. In simple plain English, forex is like the stock market but for currencies. Stock Market = Shares, forex = currencies. If you want more in-depth explanation, google is your friend. These currencies are pegged on specific countries, united states- dollar, UK- pound, euro zone- euro, Switzerland- Swiss franc, Kenya- Kenya shilling.. you get the point. Now, there are specific events and happenings between these economies that affect the movement and values of the currencies, driving their value (purchasing power up and down). Forex trading exploits these movements to make money. When the value is going up, we buy and vice versa (down –sell) Is forex trading illegal in Kenya? Is it a scam? Illegal, no. scam, no. All the banks in the world do it (KCB made about 4 billion from trading forex in 2019) Have there been scams involving forex in Kenya? Yes. Here is one that happened recently. This one is the most infamous one yet. Best believe that this is not the end of these type of scams because the stupidity, greed and gullibility of human beings is unfathomable. However, by the end of this post, I hope you won’t fall for such silliness. What next how do I make it work..? Am glad you asked. Generally, there are two ways to go about it. One, you teach yourself. This is the equivalent of stealing our dad’s car and hoping that the pedal you hit is the brake and not the accelerator. It is the route I took, it is the most rewarding and a huge ego boost when you finally make it on your own. Typically, this involves scouring the internet for hours upon hours going down rabbit holes, thinking you have made it telling all your friends how you will be a millionaire then losing all your money. Some people do not have the stomach for that. The second route is more practical, structured and smarter. First Learn the basics. There is a free online forex course at www.babypips.com/learn/forex this is merely an introductory course. Basically it is learning the parts of a car before they let you inside the car. Second, start building your strategy. By the time you are done with the babypips, you will have a feel of what the forex market is, what interests you, etc. Tip..Babypips has a lot of garbage. It is good for introductory purposes but not good for much else, pick whatever stick to you or jumps at you the first time. Nonsense like indicators should be ignored. The next step is now the most important. Developing the skill and building your strategy. As a beginner, you want to exhaust your naivety before jumping into the more advanced stuff. Eg can you identify a trend, what is a pair, what is position sizing, what is metatrader 4 and how to operate it, what news is good for a currency, when can I trade, what are the different trading sessions, what is technical analysis, what is market sentiment, what are bullish conditions what is emotion management, how does my psychology affect my trading (more on this later) an I a swing, scalper or day trader etc Mentors and forex courses.. you have probably seen people advertising how they can teach and mentor you on how to trade forex and charging so much money for it. Somehow it seems that these people are focused on the teaching than the trading. Weird, right..? Truth is trading is hard, teaching not quite. A common saying in the industry is “Those who can’t trade, teach” you want to avoid all these gurus on Facebook and Instagram, some are legit but most are not. Sifting the wheat from the chaff is hard but I did that for you. The info is available online on YouTube, telegram channels etc. am not saying not to spend money on a course, if you find a mentor whose style resonates with you and the course is reasonably priced, please, go ahead and buy..it will cut your learning curve in half. People are different. What worked for me might not work for you. Here are some nice YouTube channels to watch. These guys are legit..
After a short period of time, you will be able to sniff out bs teachers with relative ease. You will also discover some of your own and expand the list. Two tips, start with the oldest videos first and whichever of these resonates with you, stick with till the wheels fall off. How long will it take until things start making sense Give yourself time to grow and learn. This is all new to you and you are allowed to make mistakes, to fail and discover yourself. Realistically, depending on the effort you put in, you will not start seeing results until after 6 months. Could take longeshorter so there is no guarantee. Social media, Mentality, Psychology and Books Online, forex trading might not have the best reputation online because it takes hard work and scammers and gurus give it a bad name. However, try to not get sucked into the Instagram trader lifestyle as it is nowhere close to what the reality is. You will not make millions tomorrow or the day after, you might never even make it in this market. But that is the reality of life. Nothing is promised, nothing is guaranteed. Your mentality, beliefs and ego will be challenged in this market. You will learn things that will make you blood boil, you will ask yourself daily, how is this possible, why don’t they teach this in school..bla bla bla..it will be hard but growth is painful, if it wasn’t we’d all be billionaires. Take a break, take a walk, drink a glass of whatever you like or roll one..detox. Chill with your girl (or man) Gradually you will develop mental toughness that will set you up for life. Personally, I sorta ditched religion and picked up stoicism. Whatever works for you. Psychology, this is unfortunately one of the most neglected aspects of your personal development in this journey. Do you believe in yourself? Can you stand by your convictions when everyone is against you? Can you get up every day uncertain of the future? There will be moments where you will question yourself, am I even doing the right thing? the right way? It is normal and essential for your growth. People who played competitive sports have a natural advantage here. Remember the game is first won in your head then on the pitch. Books: ironically, books that helped me the most were the mindset books, Think and grow rich, trading for a living, 4 hour work week, the monk who sold his Ferrari..just google mindset and psychology books, most trading books are garbage. Watch and listen to people who have made it in the investing business. Ray Dalio, warren, Bill Ackman and Carl Icahn. This is turning out to be lengthier than I anticipated so I’ll try to be brief for the remaining parts. Brokers You will need to open up an account with a broker. Get a broker who is regulated. Australian ones (IC Market and Pepperstone) are both legit, reliable and regulated. Do your research. I’d avoid local ones because I’ve heard stories of wide spreads and liquidity problems. International brokers have never failed me. There are plenty brokers, there is no one size fits all recommendation. If it ain’t broke..don’t fix it. Money transfer. All brokers accept wire transfers, you might need to call your bank to authorize that, avoid Equity bank. Stanchart and Stanbic are alright. Large withdrawals $10k+ you will have to call them prior. Get Skrill and Neteller if you don’t like banks like me, set up a Bitcoin wallet for faster withdrawals, (Payoneer and Paypal are accepted by some brokers, just check with them.) How much money can I make..? I hate this question because people have perceived ceilings of income in their minds, eg 1 million ksh is too much to make per month or 10,000ksh is too little. Instead, work backwards. What % return did I make this month/ on this trade. Safaricom made 19.5% last year, if you make 20% you have outperformed them. If you reach of consistency where you can make x% per month on whatever money you have, then there are no limits to how much you can make. How much money do I need to start with..? Zero. You have all the resources above, go forth. There are brokers who provide free bonuses and withdraw-able profits. However, to make a fulltime income you will need some serious cash. Generally, 50,000 kes. You can start lower or higher but if you need say 20k to live comfortably and that is a 10% return per month, then you can do the math on how big your account should be. Of course things like compound interest come into play but that is dependent on your skill level. I have seen people do spectacular things with very little funds. Taxes..? Talk to a lawyer or an accountant. I am neither. Family? Friends? Unfortunately, people will not understand why you spend hundreds of hours watching strangers on the internet so it is best to keep it from them. Eventually you will make it work and they will come to your corner talking about how they always knew you’d make it. The journey will be lonely, make some trading buddies along the way. You’d be surprised at how easy it is when people are united by their circumstances (and stupidity) I have guys who are my bros from South Africa and Lebanon who I have never met but we came up together and are now homies. Join forums, ask questions and grow. That is the only way to learn. Ideally, a group of 5-10 friends committed to learning and growth is the best model. Pushing each other to grow and discovering together. Forex is real and you can do amazing things with it. It is not a get rich quick scheme. If you want a quick guaranteed income, get a job. And now it is 5am, fuck. This is oversimplified and leaves out many many aspects. Happy to answer any questions.
My Provisional List of COVID Anomalies, Red/ False Flags & Clear Indications of Scumbaggery And Scambuggery. LIHOP, MIHOP Or HOAX/SCAM? Def Not As Described. Very Much Updated Since 1st Posting. Please Let Me Know What I’ve Missed Or Add Links. Repost, Due To Strange Disappearance of 90% Of My Post.
Not going to add to my existing paranoia by speculating, but here it is updated... Here’s my Top 22 list of suspicious shenanigans and red flags surrounding the COVID narrative:
The Imperial College Death data - Neil Ferguson and Gates-funded Imperial College, London Model that ‘persuaded’ Johnson and Trump to lockdown. Projected 500K deaths in UK and 2.2m deaths in US, EVEN WITH LOCKDOWN. Less than 10% accuracy but 110% alarmist, and evidence that the coding was deliberately flawed and designed to inflate numbers. Gates funding everyone involved in the staged 'debacle'.
Thai Nhat Minh | Stably: First of all, can you have a brief introduction about yourself as well as about Chromia? Henrik_hjelte, Sergelubkin Henrik Hjelte: Hello. My name is Henrik Hjelte. I am Co-Founder and CEO of Chromia. I have more than 30 years of experience in programming and a degree in Economics from Uppsala University. BTW economics and computers = blockchain, so finally found a job that fits me. I was introduced to the blockchain by the leader of the colored-coins project Alex Mizrahi in 2013 Colored coins project was a very influential thing It was the first way for user created tokens bolted on to the only blockchain at the time (almost) bitcoin We started ChromaWay 2014, with Or Perelman too, to explore if the world was interested in “tokens” and those kind of applications We worked with enterprise blockchain for some time, but now we are focused on Chromia, a new public platform for mainstream decentralized applications using relational blockchain technology. Ok, maybe I should tell something about Chromia and not myself too. Chromia is a better blockchain for building decentralized Apps. better because it follows the “normal worlds” way of managing data. A little history: I found a text/description to paste: Chromia is a brainchild of ChromaWay. ChromaWay has a long record of delivering pioneering projects around the world. We issued Euros on the Bitcoin blockchain with LHV bank, allowed investors to invest in startups in a wholly decentralized way with Funderbeam, digitized the title transfer process with the Swedish land registry, and mediated the green bond market. ChromaWay’s core team created the world’s first protocol to issue tokens already in 2012, when blockchain was called “bitcoin 2.0”. Then ChromaWay introduced the relational model to enterprise blockchains with a consortium database called Postchain. Now Postchain is going public as the foundation for Chromia, a better blockchain for building decentralised Apps. Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. If you don’t believe me, check this blog (later, stay in the chat): https://blog.chromia.com/reasons-for-rell-compactness/ The aim of Chromia is to combine relational databases, which exist in every kind of organization, with blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications. Think about it: blockchain is about managing data (in a shared context). And… What do we use to manage data? A Database! Serge: Sure! My name is Serge! And I work in Chromia marketing department. Also, I help coordinate various projects inside the company My background is in Economics and Marketing Thai Nhat Minh | Stably: Question 1️⃣ DApp is currently mainly concentrated in the field of games, and its life cycle is basically short, just like the Crypto Kitty is only hot for a while, how to dig the application of DApp in more fields and how to improve the utilization rate of DApp? u/henrik_hjelteu/sergelubkin Serge: Good one, let me answer Gaming is quite a challenging target because good UX is expected, it needs to be fast, responsive, etc. If we can do that, then we can also do all sorts of other stuff. Also, it lets us experiment with things without a lot of hassle, it’s easier to get users, and so on. It’s also a growing niche within blockchain. You can check our latest game, Mines of Dalarnia https://www.minesofdalarnia.com We also have Enterprise projects already, for example Green Assets Wallet https://greenassetswallet.org/about that already launched on the first Mainnet version called Bootstrap Net,we also have https://capchap.se built on our tech, more projects like non-profit review platform Impactoria, public land registries, medical projects and so on Also don’t forget about our fully decentralized social network/forum that is live already on the testnet https://testnet.chromunity.com. Thai Nhat Minh | Stably: Question 2️⃣ How will dapp face the world change after the epidemic? u/henrik_hjelteu/sergelubkin Henrik Hjelte: Nobody can say for sure, but maybe people will tend to be online more than offline, so demand on online products and dapps as well will increase. I just came in from an internal demo of a secret project we do, and it can be seen as a way to hang out online (a bit cryptic answer) There are also interesting use cases of dapps in the medical field. For example, we participated in the world-wide hackathon Hack for Sweden. Where our submission was to create an app on Chromia blockchain that increases the coordination between countries and hospitals especially during the hard time and COVID19. Chromia wants to help the European Union (and the world, but we saw problems in the EU…) and its citizens to provide transparency over the necessary medical and protective devices and appliances of which we see shortage during this emergency crisis. You can watch our promo here https://twitter.com/chromaway/status/1247557274337447938?s=20. For me it was a fun Hackathon too because for once I got the opportunity to code… I told everyone else I will not do any bossing… We try to continue this path on medical applications a bit. Thai Nhat Minh | Stably: Question 3️⃣ DApps are still not directly embedded in mobile phones like Apps at this moment, and DApps have also been flooded with bet content. How can guests increase the use of DApps and lower the threshold for using DApps? u/henrik_hjelteu/sergelubkin Serge: The answer is — better User Experience. We believe that in order for a DApp to be usable and become more widely accepted it has to feel like a normal App. A DApp needs to have quick transactions, scale well & shouldn’t require users to pay for each transaction. This is something that is possible now with using Chromia. It’s an extremely exciting time since we are going to see a new generation of DApps. On top of that, we think that we might have an ace coming up. We have built a game to demonstrate the powers and possibilities of Chromia. A little bit about the game: In Mines of Dalarnia (https://www.minesofdalarnia.com), players get to explore the vast expanses of interplanetary treasure mines. With an innovative Dalarnia Token system, players can purchase virtual mining plots, and put them up for rent into the community, allowing for real-estate tycoons to earn more Tokens. Mining plots can also undergo their own upgrades, making them more lucrative to explore, as well as a hot property for rental by miners. The game takes advantage of these NFT-based tokens to securely track exchanges, and provide a sense of ownership and wealth to players as they grow their mining and resource empire. Watch our trailer https://youtu.be/bDXKOp1Asqw and sign-up for the TestNet on the website! Thai Nhat Minh | Stably: Question 4️⃣ Many practitioners think that the main reason for restricting the development of DApp is “incomplete infrastructure”. How effective is the current “cross-chain” and “side-chain” solution? u/henrik_hjelteu/sergelubkin Serge: Our infrastructure resembles Alibaba Cloud, so a DApp developer just goes and deploys his DApp’s blockchain into it, it’s easy. Also our language Rell https://rell.chromia.com/en/maste is more robust than any other blockchain programming language.Or Azure or AWS Rell combines the following features:
Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
Normal programming constructs: variables, loops, functions, collections, etc.
Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
We want people to join our channels such as telegram, twitter, email also our decentralized forum https://testnet.chromunity.com and participate in discussions
We want people to try our dapps such as Mines of Dalarnia
We want to get feedback and understand the most important issues people care about Chromia and the blockchain industry in general
We want to get more developers building on top of Chromia
LBTS: What was your motivation for creating RELL and not use other languages? What benefits? Why name it RELL also? Henrik Hjelte: We have a private/federated relational blockchain called Postchain, and it allows SQL. But that can work in a small environment when you know all parties, and if you are really careful in checking code. But not for a more secure, distributed on the web setup, so we had to make it more secure (Deterministic, statically typed). In the process, we also took the opportunity to make it cool and nice. Also: it is simply not possibly to use evm, jvm, or web assembly. We need/want a database in the bottom. Postgresql is our virtual machine. You do not reimplement that…. 10+ years codebase…. Lee: Being part of the gamer community, I would like to know what you would think about collaborating with a MOBA, RPG or Arcade game or some kind of project? Henrik Hjelte: We are already collaborating with some smaller studios. For bigger fish, we want to show them what is completely unique and visionary with Chromia, and we think we need various examples. So, first arcade game MoD (linked above) is one example, it is not the full potential or anything but a start. In this summer, krystopia 2 a puzzle game from Antler Interactive will be released. What is even cooler is the “demo project” we do together with them, where we will show how a mutliplayer game with real blockchain features will work. I just saw it an hour ago and was blown away OH, and there is another studio releasing something very cool. Full logic on chain strategy game. Chain of Alliance. oyibo pepper: Do you encourage HACKATHON programs for intending Developers to test their skills and build on RELL Can you explain more about CHROMIA AMBASSADORS PROGRAM, CAN I BECOME AN AMBASSADOR Serge: Yes, you can, but you will need to change your avatar 🤣 Seriously, we are growing our Chromians community if you want to become one please ping our admins in Chromia telegram group. Also, we are planning virtual hackathons soon, please subscribe to stay updated Infinite Crypto: Since the Chromia project is currently working on the Ethereum blockchain ERC20 standard! But we know that there are a lot of scalability issues with Ethereum, so why would you choose the Ethereum blockchain over other scalable blockchains? Do you have any plans for Mainnet launch of Chromia? Henrik Hjelte: ETH is just used in a pre-phase for tokens. We will have our own mainnet tokens interchangable with ETH. Oyinbo pepper What’s CHROMIA SSO and SDK, how can I get started Henrik Hjelte Both are 3 letters. That is what they have in common. SDK = software development kit, check docs on https://rell.chromia.com SSO = single sign on. A unique UX improvement. You approve an app in your wallet (vault) with super ease. no need to remember codes sso: https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/ We have a fundamentally different model from bitcoin and ethereum and the likes. The blockchain is not run by anonymous computers in basement and student dorms across the world. We have more of known identities, so 51% attacks is protected not by PoW/PoS but other consensus. Please see our whitepaper. Note that we are not noobs when it comes to this, our CTO Alex has published papers in academic journals on consensus etc. from 2013, and done several important ideas for blockchain. Sidechains we think he was first with, tokens too. Sheron Fernando: Is there any plan to makes partnership with local cryptocurrency developers from each country to make $CHR usage more worldwide? Serge: Yes, we are looking for cooperation with more external developers. Send me a message if you are interested in developing something on Chromia. Stella: What are the underlying problems in the Dapps today that can be solved with the Chromia protocol? Serge:
Scalability — on Chromia your dapp can have unlimited numbers of users thanks to parallel scaling
Easiness of use — you don’t need external wallets, no need to buy crypto to pay for gas etc
Cost — in general to deploy the dapp and to use the dapp
Marcel Lagacé: Why build this platform? What is Chromia mission? What are the most prominent features of the platform? Can you clarify the use case for this feature? Henrik Hjelte: We build the platform to fix the problems with blockchains, that we ourselves have experienced since 2014 (before ethereum existed). LBTS: Can you tell us about Chromia developers? How motivated and experienced are they to always deliver the best products? Henrik Hjelte: I can tell you that we recruit developers that are really good, from all parts of the world. Vietnam has been a hub because we found many good, so in Ukraine. How can we say “we have so good developers”? First one thing that is a bit different is that we are pretty experienced in leadership team of development. I do not code much anymore since I’m a CEO. But I do have now over 30 years of experience. Got published and was payed when I was 15. First full-time professional developer job at 18. Have released open-source projects used by 10: s of thousand developers. And Alex, our CTO is Extremely good. That is why I recruited him to my old startup 2006 or so… So: we have experience to sort out good developers from bad. Marcel Lagacé: Does Chromia staking model is different from other staking platform?? What are the beneficial advantages of chromia staking system? Serge: The main difference is that we have independent Providers, entities that are not connected. These serious players are exchanges, data centres, professional staking companies. They provide a backbone of the ecosystem and host dapps. Like Amazon servers in the cloud. They cannot have stake bigger than the maximum thus they can’t control the network. This is probably the main difference with classic DPoS networks Nguyen Duy Bao: A lot of people will want to know what the strength of Chromia is but I want to know the weaknesses and problems Chromia faces ? How do you plan to solve it? Henrik Hjelte: A weakness I guess is weak compared to “competition”. And there are some blockchain projects that got crazy amount of funding. So how can we compete with that, when they can hire more developers for example? Well here is what experience comes into play: More developers does not always increase productivity a lot, it is diminishing returns. You can see many large projects, with 100 of developers fail miserably with no results. And actually, sometimes true with marketing spend too. It is generally good with money, but if you are a bit clever you can compete also on marketing with less money than your competition.

We know the world is crazy, and we’ve been hard at work trying to fix the parts we think we can improve with the UBDI platform. Monetizing data isn’t easy, clients are used to scale at the size of Facebook (1B+), making it difficult for them to understand the value that can derived from just tens of thousands -- especially when their profit comes from reach, engagement and attention as people continuously come back to the platform to view and add information. UBDI’s mission is and will always be empowering people with their data to create a Universal Basic Data Income. Period. End of Story. To get there though, some changes needed to be made. We’re in the process of building (you’ll probably notice some transition states in the app) a safe place where you can anonymously communicate, learn, and earn from your data with communities of people like you. We recognized early on that there were a variety of growing pains that made linking sources burdensome, and led to long wait times for updates, failed data fetches and authorizations (oh man, those authorizations!) and an architecture that was often more confusing than alleviating (like the two app system). So we’ve been working hard to
Mitigate pain-points by:
Linking API’s directly with UBDI (so it can be a one app system, while more easily blocking fraudulent data contributions)
Ensuring this structure continues our mission to legally and technically protect you even from us
Most sources are now integrated and we are waiting on developer approval
Creating anonymous and private social features
Tribes which will allow users to privately communicate in interest groups, using data to amplify the attributes we’re most proud of
Ability to vote and post polls(coming this week) with data analytics so you can see what people like (or unlike) you think about an issue or topic. Initially you will be able to add links and (next week) we will add pictures and video -- so get ready to see lots of pictures of my dog in an animals group
Ability to anonymously comment& respond and soon… generate and choose the public traits and insights you want others to see when you comment like your Call of Duty K/D, when you first invested in Bitcoin, or how much you spend on tacos (coming soon)
More features coming this summer below!
New ways to earn
Imagine if advertisers going to Facebook or Twitter went directly to you! With all your data attributes in one place, we’re creating the best place to shift your attention, while paying you for it!
Continued proof points
We hope this passive engagement and feedback will open up new earning avenues (like personalized offers and ads) which will allow you to earn as you engage. These features will NOT be replacing studies -- in fact, we’re currently running COVID studies with the potential to earn up to $180!
Features coming this summer
Eventually, we’ll utilize the data to create fun competitions that mobilize tribes through the offering of cash awards for running the longest, gaming most, or securing the best returns on your investments.
Notifications so you actually know someone responded to your comments
Data insight stories (we’ll save this as a surprise for you but WE ARE HYPED)
Public vs Private traits on comments to show your clout
Specialized tribes that utilize public apis to generate fun and interactive insights
Reducing payout friction and fees
We’re experimenting/exploring with Uphold: This new wallet will quite literally allow you to trade your data, for gold! We hope this new payout experience would give our domestic and international users the flexibility to cheaply withdraw in the currency, or asset they feel most comfortable holding. Lower fees, better UX-- time will tell.
While opinion data is great, our mission has never been to be a survey app, instead, we have been fighting for individuals to be fairly compensated for the data they generate every day. By adding engaging features, we’re creating more ways for users to be paid for their data, while learning and engaging with other users. We understand that these are BIG changes and that some members may not love them in their early stages. We’ll continue to listen and learn from the community to understand how our new features are being received while we create a system built to last so all of you can thrive. P.S. If you’re having trouble with the app make sure it’s updated to the newest version (we push updates all the time!) We’ve also made this easier to find! If that doesn’t work, you can always shake the app to report the bug to support. https://preview.redd.it/z2r4rv77sk251.png?width=1118&format=png&auto=webp&s=bae5ae04ed14d61d603dd48d409daf51e4002f6e
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
