How to move Bitcoin data directory on MAC OSX to external drive.

Assumptions: A) Your current folder for your bitcoin data is here: "~/Library/Application Support/Bitcoin" or here "/Users//Library/Application Support/Bitcoin" B) Your current folder for your bitcoin-qt application is here: /Applications/Bitcoin-qt.app C) You have an external drive named "My Passport" and your Finder, Preferences settings are set to display Devices. Select Finder, Preferences and tick the box to the left of External disks.
To do this on a MAC running OSX 10.9 follow these instructions: 1)Open Finder. 2) In Finder, using the Finder menu bar, select: Go, Go To Folder... , and type the ~/Library and press RETURN. 3) In Finder, navigate to the "Application Support" folder. You will see the Bitcoin directory. 4) In Finder, select, or highlight, this folder, then select: Edit, Copy "Bitcoin" from menu bar. 5) In Finder, navigate to your external drive "My Passport". 6) In Finder, create a folder called "Applications" on your "My Passport" external drive (see step "C" above after connecting external drive, if necessary). 7) In Finder, navigate to the newly created "Applications" directory. 8 ) In Finder, select Edit, Paste Item to start copying the "Bitcoin" directory to your external drive's "/Volumes/My Passport/Applications/" folder. 9) Once this completes and both the "~/Library/Application Support/Bitcoin" and "/Volumes/My Passport/Applications/Bitcoin" folders are identical. Rename the Bitcoin directory in "~/Library/Application Support/Bitcoin" to "~/Library/Application Support/BitcoinOLD". 10) Launch Terminal from LaunchPad, Utilities or from Applications in Finder. 11) CAREFUL: At the Terminal prompt type: "cd ~/Library/Application\ Support" no quotes. Yes, that "\" slash is necessary. 12) Type: "ls -laf" no quotes, and insure that the Bitcoin directory is now called BitcoinOLD. 13) Type: "ln -s /Volumes/My\ Passport/Applications/Bitcoin/ ./Bitcoin" no quotes. this command actually creates a symbolic link to your external drive. Yes, that slash "\" just after the "My" is necessary to account for the space in "My Passport". 14) Launch Bitcoin-qt from Applications in Finder and let the "Reindexing blocks on disk.." process complete. It should not be downloading anything until this completes and then will download only those blocks since your last synchronize to the Bitcoin network. 15) Once this completes, delete the BitcoinOLD folder using finder. "~/Library/Application Support/BitcoinOLD". Was this helpful? Donate: 1FCZzLuH1MAa8UDaHnZKHnXmNcQRBA7Xme

How to keep the last privacy in the era of network transparency

How to keep the last privacy in the era of network transparency

https://preview.redd.it/ngfkz37opv051.jpg?width=1600&format=pjpg&auto=webp&s=896d8941338bc88da6d1199c3e2048a9aaa77c0e
Before half of 2020, the word "data breach" appears extremely active. All over the world are plagued by data breaches, but also cause major losses.
In today's Internet era, any behavior you have on the Internet is likely to be recorded, and then through big data summary and statistical analysis, you can basically say: everything you know, the network knows. In a centralized system, the system platform operator can get all your data in the background. Based on the drive of business interests, they will use this data to commercialize applications: sell data and sell services.
The world is interconnected. This is the status quo and an irreversible development trend. In this interconnection, there are no boundaries in the future. In this near future where there are no borders and everything is connected, imagine that your alarm clock, electricity meter, mobile phone, mobile detector, and other things that are needed every day are interconnected, so that others can understand your situation. What a terrible thing it is, like being in a completely privacy-free environment, such a future, you,Suffocation? Should we have privacy?
In December 1948, the United Nations promulgated the Basic Law, "Universal Declaration of Human Rights," Article 12 of which stated personal privacy as follows:
No one's private life, family, residence and correspondence must be arbitrarily interfered, and his honor and reputation must not be attacked. Everyone has the right to legal protection against such interference or attacks.
In the electronic age, privacy is essential for an open society. Privacy is different from secret. Privacy is something that someone does not want to make public. The secret is something he doesn’t want anyone to know. Privacy is a power. It gives someone the right to decide what to disclose and what not to disclose.
In a distributed Internet environment, the privacy of individuals from a macro perspective mainly covers four aspects: node privacy, content privacy, link privacy, and tunnel privacy. Let's expand one by one and look at the specific content of the four dimensions of privacy.
1) Node privacy
Node privacy refers to the fact that in an open distributed environment, both parties interacting with each other do not know each other's sensitive information, such as IP address and MAC address, so as to achieve the purpose of not exposing each other. At the same time, it is impossible for other nodes to perceive the location of the sender and the receiver through network sniffing.
The following uses the Bitcoin network topology as an example to illustrate the importance of node encryption.

https://preview.redd.it/7bwl3mqayv051.png?width=2368&format=png&auto=webp&s=b3cd22723c7b275d97754051b6a4c7d8a91be553
As of now, there are about 8,000 nodes in the entire Bitcoin network. Based on current technology, the cost of building a parallel sniffing network is very low. Some researchers have done statistics. When the topology sniffing network starts, after about 10 blocks height, it can basically infer the connection topology of the entire network. Coupled with the fixed time interval of gossip message propagation, it is basically possible to infer the general distribution position of the construction nodes of a transaction information, thereby destroying the privacy of the nodes.
2) Privacy of communication content
The privacy of communication content means that the communication content is only visible to both parties of the interaction. No one can intercept the data from the network, or without the authorization of both parties, no one can see the plain text of the communication.
3) Link privacy
Link privacy refers to the connection established by both parties in communication, which is encrypted; No one has the ability to use the link for data transmission without the relevant key. As shown in the figure below, a-> b, b-> c, c-> d, etc.

https://preview.redd.it/h0jg5ivfyv051.png?width=1576&format=png&auto=webp&s=32303d8b296da0cee4e6a4b3a744eb984aa70385
4) Tunnel privacy
In some cases, the communication between the nodes will be completed by one or more relay nodes. In this way, based on the transceiver node and the relay node, a communication tunnel is formed; tunnel privacy means that only the sending node has the right to send data from the sending node to the receiving node via the relay node. Under the premise of authorization, there is no way to complete the transmission of data. As shown above, a-> d, e-> h logical communication tunnel.
For the four privacy dimensions mentioned above, there is a general solution that can effectively protect the security. Although the communication efficiency needs to be improved, functionally speaking, it can already take into account the four dimensions. And in the following, for this general security idea, gives the possible dimensions for further optimization.
1. Description of General Encryption Network Solution
Firstly, each relay routing node in the encrypted network creates a routing descriptor, which contains some contact information, mainly IP addresses, ports, public keys, and other broadband capabilities. After the creation is complete, send this information to the directory server of the whole network (usually also become the Bootstrap node). Based on this information, the directory server generates a unique descriptor for the routing node for the entire network, which is stored on the directory server along with the descriptor information. In the following, we will describe in detail how the privacy of the encrypted network is protected from three aspects: networking topology, message structure and link transmission construction.
1) Network topology
As shown in the following figure, in an encrypted network, we recommend that clients, relay agents, relay routing nodes, directory servers, and possibly bridge nodes together form the entire network topology. When the client builds a communication link, the steps are as follows:
A. The client initiates a node request to the directory server;
B. The directory server generally recommends three nodes to the client from the directory table based on the weight selection algorithm. Logically, they are called entrance node, intermediate node and exit node.
C. After receiving effective feedback from the directory server, the client builds a complete tunnel link step by step according to the Response message.

2) Link establishment
Based on the above description, we know that a client can obtain three nodes of a link through the directory server: entrance node, intermediate node, and exit node.
A. The client uses the DH handshake protocol (Diffie-Hellman) to shake hands with the ingress node to generate a shared session key. Based on the shared key, the client sends a CREATE message to the entrance node;
B. After receiving the CREATE message, the entrance node will establish a link with the intermediate node based on the address of the intermediate node in the message and complete the key exchange;
C. Based on the segmented encrypted link and DH handshake protocol completed above, the client completes key negotiation with the intermediate node;
D. Similarly, based on the two-level encrypted tunnel established above, the client sends a CREATE message to the intermediate node to complete the establishment of the encrypted link between the intermediate node and the exit node;
E. Finally, the client completes the key negotiation between the client and the egress node based on the above three-level segmented encrypted link, and then completes the establishment of the entire onion tunnel link;

https://preview.redd.it/e8mmnz3syv051.png?width=911&format=png&auto=webp&s=de5f22a8c8b3a33ab5ff9274e2145a392b83ca04
3) Message structure and transmission
Before the message is sent from the client, it will use the shared key negotiated with the exit node, intermediate node, and entrance node to encrypt from the inside out. The innermost message is encrypted using the shared key of the exit node, then the intermediate node, and finally the entrance node.

https://preview.redd.it/aiondkuuyv051.png?width=865&format=png&auto=webp&s=a1d3a6877fbee82f668ca3fbea477b86b8b14c8a
A. After the above message is sent from the client, the entrance node will judge the validity of the message based on the shared key negotiated and remove the outer encryption, and then send it to the intermediate node;
B. After receiving the message from the entrance node, the intermediate node will judge the validity of this message based on the shared key negotiated with the client and remove the encryption of this layer, and then send it to the exit node;
C. The exit node uses the shared key negotiated with the client and repeats the above steps. Eventually send the client's message to the real destination address.
2. Optimization for the above program
In the description of the above scheme, we can easily see that there are two obvious flaws, that is, the startup node is too centralized, which can easily lead to a single point of failure or suffer from a network hijacking attack. At the same time, because the data exchange is based on link exchange, when the network congestion is severe, it is easy to cause network service delay. Due to the single structure of the message, it also restricts the data in the link transmission process to a certain extent, and optimizes the transmission performance. Below we will give specific optimization ideas based on the above two points:
1) No central server
The aforementioned encrypted network node knows the existence of all relay and entry / exit nodes by connecting to the directory server. The optimized project node will know the existence of other nodes through the local network database (tentatively called NetDB). NetDB learns the existence of more nodes when connecting other nodes through the DHT algorithm. It is a distributed network database. It mainly provides router contact information and target contact information. Each piece of data is signed by the appropriate party and verified by anyone who uses or stores it.
2) Optimization of data exchange mode
The first point to note is that in the optimized encrypted network, there are two different links for the communication link of the two parties, that is, the entrance link and the exit link are different;

https://preview.redd.it/b7es3d2yyv051.png?width=888&format=png&auto=webp&s=28da350509807d6b5a1ba60f5fb348ff5fe41ea6
In the optimized encrypted network, the connection is broken up into data packets by the message mechanism (Message), after being cross-transmitted through different TCP or UDP tunnels, the receiver reassembles into a data stream, that is, the optimized encrypted network is based on Packet switching, packet switching can drive some implicit load balancing and help avoid congestion and service interruption.
Undoubtedly, open data sharing is the source of power for the development of data-related industries, but the existing data storage methods and network protocols have many shortcomings. Solving such problems has become a very important step on the road to the next generation of the Internet world. DSP Labs has always kept thinking and exploring the next generation Internet infrastructure. I believe that in the near future, DSP Labs can bring a new choice to the Internet world.

Reddcoin (RDD) 02/20 Progress Report - Core Wallet v3.1 Evolution & PoSV v2 - Commits & More Commits to v3.1! (Bitcoin Core 0.10, MacOS Catalina, QT Enhanced Speed and Security and more!)

Reddcoin (RDD) Core Dev Team Informal Progress Report, Feb 2020 - As any blockchain or software expert will confirm, the hardest part of making successful progress in blockchain and crypto is invisible to most users. As developers, the Reddcoin Core team relies on internal experts like John Nash, contributors offering their own code improvements to our repos (which we would love to see more of!) and especially upstream commits from experts working on open source projects like Bitcoin itself. We'd like tothank each and everyone who's hard work has contributed to this progress.
As part of Reddcoin's evolution, and in order to include required security fixes, speed improvements that are long overdue, the team has up to this point incorporated the following code commits since our last v3.0.1 public release. In attempting to solve the relatively minor font display issue with MacOS Catalina, we uncovered a complicated interweaving of updates between Reddcoin Core, QT software, MacOS SDK, Bitcoin Core and related libraries and dependencies that mandated we take a holistic approach to both solve the Catalina display problem, but in doing so, prepare a more streamlined overall build and test system, allowing the team to roll out more frequent and more secure updates in the future. And also to include some badly needed fixes in the current version of Core, which we have tentatively labeled Reddcoin Core Wallet v3.1.
Note: As indicated below, v3.1 is NOT YET AVAILABLE FOR DOWNLOAD BY PUBLIC. We wil advise when it is.
The new v3.1 version should be ready for internal QA and build testing by the end of this week, with luck, and will be turned over to the public shortly thereafter once testing has proven no unexpected issues have been introduced. We know the delay has been a bit extended for our ReddHead MacOS Catalina stakers, and we hope to have them all aboard soon. We have moved with all possible speed while attempting to incorproate all the required work, testing, and ensuring security and safety for our ReddHeads.
Which leads us to: PoSV v2 activation and the supermajority on Mainnet at the time of this writing has reached 5625/9000 blocks or 62.5%. We have progressed quite well and without any reported user issues since release, but we need all of the community to participate! This activation, much like the funding mechanisms currently being debated by BCH and others, and employed by DASH, will mean not only a catalyst for Reddcoin but ensure it's future by providing funding for the dev team. As a personal plea from the team, please help us support the PoSV v2 activation by staking your RDD, no matter how large or small your amount of stake.
Every block and every RDD counts, and if you don't know how, we'll teach you! Live chat is fun as well as providing tech support you can trust from devs and community ReddHead members. Join us today in staking and online and collect some RDD "rain" from users and devs alike!
If you're holding Reddcoin and not staking, or you haven't upgraded your v2.x wallet to v3.0.1 (current release), we need you to help achieve consensus and activate PoSV v2! For details, see the pinned message here or our website or medium channel. Upgrade is simple and takes moments; if you're nervous or unsure, we're here to help live in Telegram or Discord, as well as other chat programs. See our website for links.
Look for more updates shortly as our long-anticipated Reddcoin Payment Gateway and Merchant Services API come online with point-of-sale support, as we announce the cross-crypto-project Aussie firefighter fundraiser program, as well as a comprehensive update to our development roadmap and more.
Work has restarted on ReddID and multiple initiatives are underway to begin educating and sharing information about ReddID, what it is, and how to use it, as we approach a releasable ReddID product. We enthusiastically encourage anyone interested in working to bring these efforts to life, whether writers, UX/UI experts, big data analysts, graphic artists, coders, front-end, back-end, AI, DevOps, the Reddcoin Core dev team is growing, and there's more opportunity and work than ever!
Bring your talents to a community and dev team that truly appreciates it, and share the Reddcoin Love!
And now, lots of commits. As v3.1 is not yet quite ready for public release, these commits have not been pushed publicly, but in the interests of sharing progress transparently, and including our ReddHead community in the process, see below for mind-numbing technical detail of work accomplished.

Whew! No wonder it's taken the dev team a while! :)
TL;DR: Trying to fix MacOS Catalina font display led to requiring all kinds of work to migrate and evolve the Reddcoin Core software with Apple, Bitcoin and QT components. Lots of work done, v3.1 public release soon. Also other exciting things and ReddID back under active dev effort.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

NordVPN's network isn't as big as some of their competitors, so if you're attempting to obfuscate your tracks, you might want a company with more servers. Otherwise, this business is plainly offering a winning offering.
Their finest plan is 1-year membership strategy: $6.99 ($ 83.88).

CyberGhost has actually been around because 2011 and has come out strongly as an advocate of "civil rights, a complimentary society, and an uncensored Internet culture." We truly liked how the company specifically showcases, on their Website, how folks usually prevented from accessing such essential services as Facebook and YouTube can bring those services into their lives by means of a VPN.
The company has strong Linux assistance, supports VPN through routers, and has a solution for the popular Kodi media player. They mark off all the boxes on procedure support and get congratulations for offering a connection kill switch function, in addition to supporting P2P and BitTorrent in most nations.
Still, the few extra dollars deserve it. We liked how the business offers custom-made app security, IPV5 support and DNS, IP, and WebRTC leakage prevention. CyberGhost also picked up points for preserving privacy by not logging connection information.

Country/Jurisdiction: United States.

A big win for IPVanish is the reality that the business keeps no logs. Absolutely no. We also like the business's stance towards privacy. They even supply support to EFF, the Electronic Frontier Foundation, a not-for-profit at the front lines of securing online personal privacy.
An unique feature of IPVanish, and one we're extremely interested by, is the VPN's assistance of Kodi, the open-source media streaming app that was as soon as referred to as XBMC. Any severe media fan has used or constructed Kodi or XBMC into a media player, and the integrated IPVanish Kodi plugin provides access to media worldwide.
At $7.50/ month and $58.49 for a year, they're undoubtedly attempting to move you towards their annual program. We awarded the business congratulations for Bitcoin support, and their money-back guarantee. We're a little disappointed that they just allow a 7-day trial, instead of a full 30-days. The company is generous, with five simultaneous connections. We also liked their connection eliminate switch feature, a must for anyone serious about staying confidential while browsing.

PureVPN does not log connection details. We like that they provide a 30-day refund policy. They got perk points because, essential for a few of our readers, PureVPN supports bitcoin payments and you're going like their fast performance.
Also, you can grow with them. If after a long time, you require to scale up to business-level plans, the business has offerings for development. Prices is middle-of-the-road, at $10.95 each month and $35,88 annually.
Finally, we like that PureVPN has both Kodi and a Chromebook solution called out right on their Web page. In addition, PureVPN earns the distinction of being the very first VPN service we've seen to totally implement the GDPR.

Variety of servers: 689.
Variety of server places: 70.
$ 5.83/ month (42% discount rate) for a 1-year strategy.
StrongVPN blasts onto our favorites list with outstanding facilities and good price efficiency. As with our other favorites, StrongVPN has a strong no-logging policy. Since VPN is all about securing your personal privacy, that's a place the savvy VPN service providers can get points.
Strong likewise picks up congratulations for its large base of IP addresses, which also helps protect your anonymity. They have a strong collection of servers and around the world locations. For those of you who need a devoted IP, you can get one from the company, however you'll require to contact support to get assist setting it up.

Variety of servers: 1500.

Country/Jurisdiction: US.
$ 39.99 for the first 12 months.
Symantec, long understood for quality in security items, has a fairly minimal offering in its VPN item. It does not support P2P or BitTorrent, it does not have a kill switch feature, and it does not support Linux, routers or set leading boxes.
On the other hand, it's a VPN product from Symantec, a publicly-traded business with a clearly recorded management team. In many software application classifications, this might not be a notable advantage, but in the VPN world, where most companies have shadowy management and impossible-to-track-down ownership structures, it's revitalizing to understand exactly who we're handling and understand through independent sources (the company's annual filing, the SEC, and analyst reports) that the company is reliable and liable.

Hotspot Guard.
Variety of IP addresses: 50,000.
Number of servers: 2500.
Number of server places: 26.
$ 2.99/ month (77% discount rate) for a 3-year strategy.
HotSpot Shield is an item that has actually had some ups and downs in regards to our editorial protection. Back in 2016, they picked up some really favorable protection based upon founder David Gorodyansky remarks about protecting user personal privacy. Then, in 2017, a personal privacy group implicated the company of spying on user traffic, an accusation the company flatly denies. Lastly, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Thankfully, that was repaired right away.
So what are we to make from HotSpot Guard? Frankly, the debate caused us to drop them from our directory for a while. However they approached us, made a strong case for their ongoing dedication to privacy, and we chose to give them another chance.
Here's the good news. They use one of the very best money-back warranty we have actually seen for VPN services, a complete 45-days. They support Windows, Mac, iOS, and Android, along with plugins for Chrome and Firefox. They also support routers and media players (but not Linux). And, as a reward, they have a connection kill switch feature.
The business does not support P2P or BitTorrent-- and they also don't support the OpenVPN. Every other supplier does, but HotSpot Shield limits its protocol assistance to L2TP/IPSec and something they call Hydra, an enhancement of the transport protocol.
Overall, the company did impress us with their attention to personal privacy. They have actually a released personal privacy canary. They likewise informed us, "We have actually integrated in malware, phishing and spam security. Our dedication to our users is that Hotspot Guard will never ever keep, log, or share your real IP address.".

Country/Jurisdiction: UK.
$ 2.99/ month for 3-year strategy.
We have to provide these folks an extra shout-out just for the name of their service. The company has a strong network with an excellent selection of protocols supported. While they have a comprehensive (and really plainly written set of policy documents), the company clearly permits P2P and gushes.
We like how HMA provides assistance on a wide variety of devices consisting of video game consoles. We gave them kudos for bitcoin support, and their outstanding money-back guarantee. They did make us frown a bit since they do log connection data. They also use five synchronised connections.
While their monthly pricing of $11.52 is at the high end of the spectrum, their yearly rates is competitive at $78.66 for a full year.

Variety of servers: 700+.
Variety of server locations: 70+.
Country/Jurisdiction: Switzerland.
30-Day Cash Back Guarantee.
$ 2.99/ month for 3-year strategy.
VyprVPN has the largest bank of IP addresses of any of the services we have actually taken a look at. The business provides a wide range of procedures, including its own high-performance Chameleon connection procedure.
We like that the company provides a connection kill switch feature and, for those who require it, there's a choice to get a dedicated IP address. VyprVPN is a standout in their effort to offer privacy, and ward off censorship. When China began its program of deep package VPN assessment, Golden Frog's VyperVPN service added scrambled OpenVPN packets to keep the traffic streaming.
At $9.95 for a month's service, and $80.04 for a year, the service is a good deal.

Variety of servers: 3,252.

Country/Jurisdiction: United States.
Mentioning rate, if you desire a strong VPN service provider and you want the lowest yearly rate anywhere, Private Web Access is the location to go. At $6.95 a month, their regular monthly charge is the second least expensive of our choices, however at $39.95 per year, Private Internet Access beats even the second most affordable annual price by a complete Jackson (a $20 expense).
The company does not launch details on the variety of IP addresses offered, but at 3,252, their server count is more than any of our other choices.
These folks have been around given that 2010, and do not log anything. They supply a generous five connections, a connection kill switch feature, and some excellent online documentation and security assistance. Our one dissatisfaction is that their refund policy is 7-days rather of 30, however you can definitely get a feel for their exceptional efficiency in the area of a week.

TorGuard.
Variety of IP addresses: N/A.

Despite the fact that the business doesn't launch the number of IP addresses it supports, TorGuard didn't disappoint. In addition to standard VPN services, TorGuard uses a wide array of additional services, depending upon your personal privacy requires.
Just like our other favorites, TorGuard keeps no logs whatsoever. They have a full suite of protocol support, so no matter how you want to connect, you can have your choice. We likewise like the active blog site the company keeps. It's relevant and intriguing to anybody with Web security concerns.
While TorGuard only offers a 7-day return policy, it's enough time for you to be able to decide if you're pleased. The monthly rate of $9.99 is practically at the middle of the range, but the yearly fee of $59.99 is a deal compared to practically all our other competitors.

Buffered VPN.
Variety of IP addresses: 11,000.
Number of servers: 800.
Variety of server locations: 46.
Country/Jurisdiction: Gibraltar.
Buffered VPN doesn't disclose much about the size of its network, however the 30-day refund ensure suggests that you can take their service for a test drive and really get a feel for how well it carries out for you. The business distressed us due to the fact that they do keep some connection information. They cheered us up, though, due to their client support, limitless bandwidth, and generous number of simultaneous sessions permitted.
The company is reasonably new, established in 2013. It's based in Europe, so those who choose an EU-based business might choose Buffered. We like how Buffered has made a strong dedication to Web liberty, and an equally strong dedication to supplying quality customer support.
At $12.99 monthly and $99.00 for a year of service, they do not provide the least costly plan, but we do suggest providing a shot.

goose.
Goose VPN.
Variety of IP addresses: 8.
Variety of servers: 8.
Number of server locations: 39.
I needed to know why Goose VPN was so named. My very first order of business was to connect to the company's co-founder and ask. Geese, I was told, make exceptional guard animals. There are records of guard geese providing the alarm in ancient Rome when the Gauls assaulted. Geese have been utilized to secure an US Air Defense Command base in Germany and a brewery in Scotland.
It's clear that the goose is an ideal mascot for a service that's suggested to guard your digital communications. And so, we have Goose VPN.
Goose VPN has a number of standout features. Initially, you can have a limitless variety of synchronised connections (or gadgets) using the VPN at once. Second, if your bandwidth requirements are 50 GB or less per month, you can register for $2.99/ month, the most inexpensive monthly rate we have actually seen.
If you desire unlimited bandwidth, the company definitely is pushing you towards purchasing a year at a time. Their regular monthly cost for unrestricted bandwidth is a middle-of-the-road $12.99/ month, but if you invest $59.88 for a year's service, you'll find it's the second least expensive by-the-year price of the services we have actually examined.
Goose supplies all the typical clients, including iOS, Android, Mac, and Windows, and adds assistance for routers, Android TELEVISION, and Linux. They are dealing with a kill switch function, which may even be up and running by the time you read this evaluation. The company also provides 24/7 ticket-based support.
Ducks quack, geese honk, and swans whoop (we know, because we looked it up). Overall, particularly provided the limitless connections and low yearly rate, we believe Goose VPN is something to beep about.

Surfshark.
Variety of servers: 800+.
Variety of server locations: 50.
Country/Jurisdiction: British Virgin Islands.
While Surfshark's network is smaller than some, they make it up on functions. Let's start off with the greatest win they provide: endless device assistance. If you want to run your whole home or office on Surfshark's VPN, you don't have to worry about the number of gadgets you have on or linked. They also use anti-malware, advertisement stopping and tracker blocking as part of their software application.
The company has a solid variety of app support, running on Mac, Windows, iOS, Android, FireTV, and through routers. We particularly like the feature that permits you to whitelist certain apps and websites to instantly bypass the VPN. For some service usage, this can be seriously crucial.
Surfshark also offers three special modes developed for those who wish to get around limitations and more thoroughly hide their online footsteps. Camouflage Mode masks your VPN activity so your ISP does not know you're utilizing a VPN. MultiHop dives your connection through multiple nations to hide your trail. Lastly, NoBorders Mode "allows [you] to successfully use Surfshark in restrictive areas." Just be careful. Doing any of these three things might be illegal in your nation and could lead to really extreme penalties.
For a year plan, Surfshark can be found in very close to much of the other full-featured VPN suppliers, at $71.88 for the first year. Take care, because it looks like that will jump to $143.40 after your very first year is up. Month-by-month plans are $11.95. Their finest deal is $1.99 a month, for their 24 month strategy (you pay $47.76 up front). Absolutely benefit from their generous 30-day trial to choose if you like this service (and possibly set a reminder in 23 months to see if you can talk them into a continued discount rate).

WEBROOT LOGO.
Webroot WiFi Security.
Country/Jurisdiction: United States.
Beginning rate: $39.99.
As VPN services go, Webroot WiFi Security is relatively bare-bones-- but it's also low-cost. Starting at $39.99 for a year of VPN service, you can get a package with both VPN and Webroot's antivirus software for $69.98 for your very first year. Sadly, both of these costs bump up after the first year. VPN security leaps to $59.99 and the package jumps to $119.98.
While we praise the combination of VPN and anti-viruses in one package, Webroot has had a troubled few years. In 2017, it wrongly flagged Windows' system files as malicious. In 2018, a kernel exploit was found in the business's Mac anti-virus client. In 2019, the company was acquired by backup company Carbonite.
If you're only safeguarding a couple of gadgets and wish to conserve loan, Webroot's VPN might be for you. That $39.99 rate is for as much as three devices. If you wish to protect 5 devices, you'll require to pay $59.99 for a year and $79.99 after that. Honestly, as soon as you get in that price variety, there are products with more abilities readily available.
Webroot's VPN is also light on protocols. While they do link utilizing IKEv2 by default, they likewise provide L2TP and the very old and very insecure PPTP protocol (although they do warn that it's not "as" protect. Another concern for those of you who need deep security is that the business does log both which VPN server location you link to and the nation you connect from.
So who is Webroot's VPN for? If all you wish to do is protect your Wi-Fi connection while browsing in your local cafe or at a hotel, you only require to connect a couple of devices, and you wish to save money, this is a convenient alternative. However if you require a major VPN with deep capabilities, you'll want to look elsewhere in this directory. Likewise, we didn't discover any reference to a money back warranty, so check with their pre-sales and support prior to purchasing.

VPN FAQ
Since we're living in a connected world, security and privacy are critical to ensure our personal safety from nefarious hacks. From online banking to communicating with coworkers on a daily basis, we're now frequently transferring data on our computers and smartphones. It's extremely important to find ways of securing our digital life and for this reason, VPNs have become increasingly common.
What Is a VPN?
A virtual private network (VPN) is a technology that allows you to create a secure connection over a less-secure network between your computer and the internet. It protects your privacy by allowing you to anonymously appear to be anywhere you choose.
A VPN is beneficial because it guarantees an appropriate level of security and privacy to the connected systems. This is extremely useful when the existing network infrastructure alone cannot support it.
For example, when your computer is connected to a VPN, the computer acts as if it's also on the same network as the VPN. All of your online traffic is transferred over a secure connection to the VPN. The computer will then behave as if it's on that network, allowing you to securely gain access to local network resources. Regardless of your location, you'll be given permission to use the internet as if you were present at the VPN's location. This can be extremely beneficial for individuals using a public Wi-Fi.
Therefore, when you browse the internet while on a VPN, your computer will contact the website through an encrypted VPN service connection. The VPN will then forward the request for you and forward the response from the website back through a secure connection.
VPNs are really easy to use, and they're considered to be highly effective tools. They can be used to do a wide range of things. The most popular types of VPNs are remote-access VPNs and site-to-site VPNs.
What is a remote-access VPN?
A remote-access VPN uses public infrastructure like the internet to provide remote users secure access to their network. This is particularly important for organizations and their corporate networks. It's crucial when employees connect to a public hotspot and use the internet for sending work-related emails. A VPN client, on the user's computer or mobile device connects to a VPN gateway on the company's network. This gateway will typically require the device to authenticate its identity. It will then create a network link back to the device that allows it to reach internal network resources such as file servers, printers and intranets, as if it were on the same local network.
It usually relies on either Internet Protocol Security (IPsec) or Secure Sockets Layer (SSL) to secure the connection. However, SSL VPNs can also be used to supply secure access to a single application, rather than an entire internal network. Some VPNs also provide Layer 2 access to the target network; these will require a tunneling protocol like PPTP (Point-to-Point Tunneling Protocol) or L2TP (Layer 2 Tunneling Protocol) running across the base IPsec connection.
What is a site-to-site VPN?
This is when the VPN uses a gateway device to connect to the entire network in one location to a network in another location. The majority of site-to-site VPNs that connect over the internet use IPsec. Rather than using the public internet, it is also normal to use career multiprotocol label switching (MPLS) clouds as the main transport for site-to-site VPNs.
VPNs are often defined between specific computers, and in most cases, they are servers in separate data centers. However, new hybrid-access situations have now transformed the VPN gateway in the cloud, typically with a secure link from the cloud service provider into the internal network.
What is a mobile VPN?
A traditional VPN can affect the user experience when applied to wireless devices. It's best to use a mobile VPN to avoid slower speeds and data loss. A mobile VPN offers you a high level of security for the challenges of wireless communication. It can provide mobile devices with secure access to network resources and software applications on their wireless networks. It's good to use when you're facing coverage gaps, inter-network roaming, bandwidth issues, or limited battery life, memory or processing power.
Mobile VPNs are designed and optimized to ensure a seamless user experience when devices are switching networks or moving out of coverage. It generally has a smaller memory footprint, and because of that, it also requires less processing power than a traditional VPN. Therefore, it enables your applications to run faster while the battery pack is able to last longer.
A Mobile VPN is a worthwhile tool to have since it increases privacy, user satisfaction and productivity, while also reducing unforeseen support issues caused by wireless connectivity problems. The increasing usage of mobile devices and wireless connectivity make it more important to ensure that your data is being transferred through a secure network. It will allow you to access the internet, while staying safe behind a firewall that protects your privileged information.
Who needs a VPN?
Individuals that access the internet from a computer, tablet or smartphone will benefit from using a VPN. A VPN service will always boost your security by encrypting and anonymizing all of your online activity. Therefore, both private and business users can benefit from using a VPN. Communications that happen between the VPN server and your device are encrypted, so a hacker or website spying on you wouldn't know which web pages you access. They also won't be able to see private information like passwords, usernames and bank or shopping details and so on. Anyone that wants to protect their privacy and security online should use a VPN.
How to choose a VPN Service?
There's a vast range of VPN servers on the internet. Some are free, but the best ones require a monthly subscription. Before you decide to download a VPN, make sure you consider these factors for understanding a VPN:
Cost - VPNs aren't too pricey, but they vary from vendor to vendor. If your main concern is price, then go with something inexpensive, or free - like Spotflux Premium VPN or AnchorFree HotSpot Shield Elite. By all means, try a free server but they do have a few drawbacks since they attract a lot of users. Free servers are often slower, and since most are ad-supported, they place adverts on the online pages you access. Others can even limit the speed of your connection, as well as your online time or amount of data transferred.
It's also important to note that leading VPN providers such as NordVPN and Privacy Internet Access offer stronger security features to ensure you're digitally safe. When selecting a paid VPN service, always be sure to check which countries it operates servers in.
Reliability - Select a VPN that is reliable and read the reviews to make sure that it's capable of protecting you by providing you with sufficient online privacy.
High security - An effective VPN will have the following security features: 128-bit encryption, anonymous DNS servers and an absence of connection logs.
Are there any bandwidth limits? This can often be linked to price; paying more will generally provide more bandwidth with faster internet access.
Are apps for Android, iOS phones and tablets available? Apps for Android and iOS devices are also vulnerable, so make sure your VPN server can support them.
To ensure privacy, you want to make sure you have a VPN that doesn't store online logs. Some servers provide virus and spyware protection, and features like that can significantly increase your online safety.
Using a no-logs VPN service will provide you with a higher degree of security. It can protect you from blanket government surveillance and prevent your internet service provider from knowing your online activity.
Using a VPN for Netflix and other forbidden treasures
Online streaming services like Netflix and Hulu have been making it difficult for foreign users to access their content in other countries. Many people can get around region restrictions by using a VPN service to route your traffic through another country.
It can be quite simple to watch Netflix and other restricted goodies. You'll have to use a VPN service that allows you to get a unique IP address. This can often be available for an additional fee. Look for VPN services that offer a "dedicated IP address", "dedicated IP", or "static IP." Additional features like these will always allow you to access content from Netflix through a VPN service.
This is by far the easiest way to access your forbidden apps since there's no specific way to block VPN traffic.
A lot of people started using a VPN to evade geo-restrictions. But despite its forbidden benefits to users outside the US, a VPN is a great tool that can protect you and enhance your online experience over the internet by providing you with sufficient security and privacy. When it comes to selecting the best VPN, you have plenty of choices. There are many cost-effective VPN options, and all of them will vary in monthly offerings. Choosing the best VPN is easier once you narrow down the competition. The best indication of a good VPN service provider is that they have the right security and the right support in place for you.

I am so sorry BCH community, please accept my apology.

I'm sorry BCH community. I always thought this was just another scam. I've falling for all the brainwashing online and never believed in anything other than bitcoin.
It's been easy for me to believe what I wanted to believe and I'll explain why I wanted to believe in BTC. I first heard of bitcoin 6 years ago and I shrugged it off as being something that's pointless, each year after that there was another article that caught my eye about the huge rise in value, everytime I saw it (not lying - every year I saw it), I thought damnit! I should just have bought it, but I guess it's too late now.
A few years later I bought some Ethereum, it was VERY cheap so I bought it, even though I didn't understand it at all (it was very cheap, I bought hundreds with the hopes that it will do what BTC did), I completely forgot about it, and two years later a friend told me ETH was $400 - I rushed to open up my wallet and sync it and realised I don't remember the password, this would've been worth millions, in otherwords I would have had true freedom. I spent around 3 months researching ways to try and recover my password and eventually realised that there is no way, at this point my mac got extremely slow (I blame Sierra) and I had to format / reinstall it. I figured there's no point in taking a backup of the eth directory as I don't have the password to decrypt the wallet anyway, so I nuked it and said goodbye to my freedom.
Now, fast-forwarding, me and my girlfriend are switching phones (she wants and iPhone, I want an Android), the next step for me was to move all my data from the iPhone to the droid (Google Authenticator, mail accounts etc.) as I got to my Notes application I found a note containing my ethereum wallet password. I cannot explain to you how sick this made me feel, even just thinking back about it now is making me feel queesy.
I could have had true freedom, I could get myself, my girlfriend and our child out of South Africa to be in a better country, with lower crime rates, less risk of my rape - better education etc. I could have said goodbye to all of my stress and worries - the long 16 hour work days, it would all have been gone, but I screwed it up - twice.
This made be feel sick and I stayed away from crypto for longer, last year (2016), was the year I decided that I am sick and tired of worrying about our futures, sick of worrying about a robery or a hijacking, sick and tired of long working hours and almost 2hour long commutes on a dangerous freeway. This was the year that I would get into crypto. The first thing I realised is that my reasoning for entering crypto was to seek financial freedom, I didn't just want to buy and hold a currency, I wanted to help the community and make some money doing it, so I took a loan - and built a rig (cheap GTX 1060s) - so far it's helped a lot, the money I've been mining helped keep my nose above water. I haven't been able to pay off the loan yet, but atleast the monthly expenses are all covered.
I decided to keep money aside and save it (instead of buying new cards every n months) into a type of savings account, where I'll keep it until it's enough to build another rig, the second rig will help my pay off the loan, but there's no point in spending the cash on parts that are useless on their own. It worked out pretty well, but unfortunetly even after the doubling of BTC price, it's still not enough for a new rig - however I believe I can get there, the reason I wanted you guys to be wrong is that you were a contradiction to everything I was led to believe the last couple of months and this project (the reports of the "flippining" threatened my survivability).
This latest "dip", hurt a lot, where it went from $20k to $14k - I was close to buying the new rig, I was actually trying to move my BTC from my wallet to Luno so I can sell it - and I saw that my transaction fee was huge, the fee was something like ZAR 1600+, I just couldn't spend it - so I decided to keep holding until Lightning was implemented, and now it dipped - hard :( So I'm still left holding the bag.
I was hurt by these fees, so damn much that I couldn't get my cash out - and I realised how bad it is, I also realised that at the very least Segwit2x could've been implemented to relieve some of this (or atleast minimize the effect), but it just didn't get implemented and I feel that it's disgusting, do they not realise by ignoring the original 'Peer to peer cash system' use-case that some people are getting very hurt through this? I mean - what's the point in a "decentralised" currency if it can be controlled by a central authority (blockstream) - and they hurt the consumers, why didn't I just use a bank to store my savings for my new rig, it would sure as hell have hurt alot less (TX fees to send from Bank to computer shop would have been around ZAR 6 ffs).
Now, I know this is longwinded, but I would like to apologise for thinking every BCH supporter is an idiot/liescammer, the only thing I can say is that I didn't understand it - I didn't understand what you guys were so upset about, until now - and I feel terrible for the few downvotes I made, I feel sorry for saying something like "don't support evil people" when the BCH crowd is trying to keep BTC from collapsing. I feel terrible about it, I really do.
I hope you guys can forgive me, I truly do - I will try my best to educate myself and help others, I will make it my mission. The only thing I ask now of the BCH community, is if someone knows of an easy/cheap/safe way to exchange my BTC for BCH, without those huge TX fees, I am sorry to ask, I know I don't deserve your help, but I'm desperate and running out of time, I'm starting to feel the pressure and I need to get rig x2 up as soon as possible, before life becomes even more uncomfortable.
Thank you for taking the time to read my apology.

(Upvote to the top) > SOLUTION FOR ZCLASSIC Eleos Wallet: "Wallet daemon can not be run. Check if daemon does not already run"

So I noticed a lot of people recently (including myself) are experiencing the error "Wallet daemon can not be run. Check if daemon does not already run" when trying to open up their ZCL Eleos wallet, and people are unable to access their funds or cannot export their private keys as well. A solution to this is now official (thanks to JBrutWhat from the BTCP team for helping me out on this.) Note: Post is being edited as more info becomes available to me.
This solution also works for users who are on the ZClassic Swing wallet experiencing the error "A general unexpected critical error has occurred: error: Couldn't connect to server, see the console output for more detailed error information!."
Eleos Wallet Troubleshooting section
ZClassic Electrum Wallet
  1. Create a new standard wallet and restore the 2FA wallet using your "seed" codes. DO NOT password protect this wallet.
  2. Disable the 2FA feature when presented with the option.
  3. Navigate to C:/Users/YOUR-NAME/AppData/Roaming/Electrum-zcl/wallets. Open the new standard wallet file with Notepad.
  4. You will need to gather the 2 private keys and one public key. To find this easily, press “CTRL+F” and search for “xprv”. Copy the 2 “xprv” values as well as the last “xpub” value. You will need these in a later step.
  5. Create a new “Multi-signature wallet”. Select “From 3 co-signers” on the first slider. Select “Require 2 signatures” on the second slider.
  6. To add the first co-signer, click “Use public or private keys”. Enter the first xprv key in this box.
  7. Add the second co-signer via a private key also.
  8. Add the third co-signer with the public key. Complete the set-up.
  9. Your wallet funds now have the ability to be sent from the multi-signature wallet.
For Users who were already using the Electrum wallet beforehand, you can go to file > new/restore wallet > next > import zclassic private keys and input the private key you obtained from the walletaid tool, and it should import the wallet into the electrum wallet. Then from there, go to file > backup wallet and export a copy of the wallet.dat file onto an offline USB.
Reminder: Backup and delete the private keys file from your desktop pc/hard drive, move it into an offline USB for safekeeping. Do not leave it on an online device.
Donate to me if you found the guide useful! Your donations 100% voluntary but they are greatly appreciated and keep us going!

14 Tips To Secure Your Mac - Security & Privacy how to restore bitcoin wallet from an old file or drive Explained Bitcoin, Cryptocurrency and Blockchain Technology & Twitter hack  Marathi  Dheera How to Show Full Path for File in Finder on macOS 10 How to make a directory/folder using Mac Terminal

By default, Bitcoin (or bitcoind) will look for a file named 'bitcoin.conf' in the bitcoin data directory, but both the data directory and the configuration file path may be changed using the -datadir and -conf command-line arguments. It might be worth noting that it is also possible to specify a custom data directory, using the -datadir=<path-to-folder> option from command line. This actually allows to have multiple running instances of bitcoin: you just need to run bitcoind/bitcoin-qt twice, specifying two different data folders. – FedFranz Oct 24 '17 at 16:36 By default Bitcoin will put its data here: ~/.bitcoin/ You need to do a "ls -a" to see directories that start with a dot. If that's not it, you can do a search like this: find / -name wallet.dat -print 2>/dev/null Mac.
