BCH News Roundup: Transactions Spike, Cashaddr Support, and a Developer Congress

The last seven days have been busy within the Bitcoin Cash ecosystem with a slew of announcements and developments. Kraken exchange recently added the BCH-based Cashaddr address format and Coinbase open-sourced a utility that makes it easy to convert between Base58 and Cashaddr addresses. Additionally, the New Hampshire-based Anypay payment processor is bolstering merchant adoption by offering 10% bitcoin cashback for purchases through their point of sale services.

Bitcoin Cash Markets Hold Steady While Transactions Per Day Keep Rising

In the past week, the BCH market capitalization ($ 5.55 billion) has surpassed LTC but BCH markets are down roughly 7.8% during this period. Each BCH is swapping for $ 309 per coin and there’s around $ 1.19 billion in global bitcoin cash volume. The top exchanges trading the most BCH on Saturday, August 10 include Coinbene, Digifinex, Hitbtc, Bibox, and Okex. Right now the top trading pairs swapped against BCH are USDT (52%), BTC (28%), USD (8.7%), ETH (6.8%), and KRW (2%).

One of the biggest metrics rising over the last few weeks for BCH has been the number of daily transactions. BCH miners have been processing an average of 35-40,000 transactions (txn) per day and there have been multiple 24-hour periods above 60,000 txn per day. The influx of daily transactions is likely attributed to the Simple Ledger Protocol (SLP) tokens which have seen significant usage in recent weeks.

Kraken Adds Cashaddr and Coinbase Open Sources a Cashaddr Utility

On August 8, the San Francisco-based Kraken exchange revealed that the trading platform is switching over to BCH Cashaddr-based addresses for all deposits starting August 15th. The cryptocurrency ecosystem transitioning from the legacy address format to the Cashaddr format is very important to the BCH ecosystem. The Cashaddr address system was deployed on January 14, 2018, and since then many third-party service providers have adopted the format. Bitcoin ABC lead developer Amaury Séchet explained on Thursday that he had contacted Kraken a few weeks ago and asked them to switch to Cashaddr. “I am happy to see Kraken implement this change — It benefits users by helping them avoid mistakes when depositing funds,” Séchet remarked.

In addition to Kraken adding the Cashaddr format, software engineer Josh Ellithorpe and Coinbase open-sourced a utility to convert between base58 and Cashaddr BCH addresses. The news was welcomed by the BCH community and people hope the utility introduced by Coinbase and Ellithorpe will bring more visibility to the Cashaddr format. Electron Cash developer Calin Culianu (Nilac the grim) explained that there’s open source code for Cashaddr in Python, JS, C++, Go, and more as well.

Anypay Offers BCH Cashback Promo

On Friday the crypto payment processing startup Anypay Global announced a 10% BCH back bonus for people spending bitcoin cash using the company’s system. The following day Reddit user u/Bitcointippingpoint revealed that there are 30 merchants in New Hampshire that accept crypto through Anypay and 27 of these retailers accept bitcoin cash. New Hampshire is known as the “Free State” for its large number of libertarian residents.

Seven of the BCH merchants are located in Keene, says Bitcointippingpoint and another six BCH-accepting merchants are located in Portsmouth. “14 of the 30 have accepted a payment within the last week,” the Reddit user announced. “Can attest to using this at the Fresh Press in Portsmouth, New Hampshire — It’s pretty sweet,” explained another Reddit user discussing the 10% BCH cashback promotion for purchases through Anypay’s point-of-sale. Anypay also provides a map of all the crypto accepting merchants

Developer Tendo Pein Reveals Spending Constraints With OP_Checkdatasig

This week the creator of the BCH-based programming language called Spedn wrote a blog post on Honest.cash which detailed some interesting schemes that can be developed using the opcode OP_Chechdatasig. On August 8, Tendo Pein told the BCH development community that one of the limitations of BCH Script was that you can only specify if one can spend the coin. However, people assumed there was no way of adding spending constraints but Pein shows how it’s now possible. Pein shows three types of constraints like a simple scheme like a Pay to Public Key Hash. Then the developer shows some more complex ideas that can be achieved and uses the Spedn language to show the benefits more clearly. During the end of the post which shows another example of a spending constraint dubbed “the fanciest,” Pein demonstrates how OP_Return tokens could be miner enforceable. This particular demonstration could make OP_Return tokens built on top of the chain stronger by backing them with the network’s security.

Txhighway Visualizer Adds New Features

With the number of daily transactions picking up on the BCH chain, many supporters noticed a few issues with the transaction visualizer Txhighway.com. Since then the site’s maintainer fixed the website’s Websockets and updated the page. The Txhighway website shows a large 32-lane highway for the Bitcoin Cash network while the Bitcoin Core (BTC) network has two lanes available and during periods of BTC congestion the website gives a unique perspective of the problem. Now there’s new logos, no reference to older BSV projects, and there’s now a Badger button available for donations. Additionally, with the popularity of SLP tokens on the rise, the highway also shows Spice token transactions on the move as well.

Bitcoin Cash City Conference and the BCH Developer Congress

Overall, the Bitcoin Cash ecosystem and its participants continue to truck forward after celebrating the recent two-year anniversary of BCH. In addition to the anniversary celebrations, BCH supporters are gearing up for the Bitcoin Cash City two-day conference next month in North Queensland, Australia. On August 8, Cointext CEO Vin Armani announced an open call to all the developers who work on BCH infrastructure and provide BCH products and services to attend the first “Developer Congress.”

The BCH developers’ meeting will take place between September 3-5 in coordination with the Bitcoin Cash City conference. This weekend, news.Bitcoin.com spoke with Armani about the event and what will be discussed.

“The Bitcoin Cash Developer Congress is an initiative, sponsored by Bitmain, with the primary purpose of bringing together developers from across the Bitcoin Cash ecosystem to discuss and debate upcoming projects and protocols which will be put into production within the next 12 months,” the Cointext CEO explained.

How to Become a Blockchain Developer

August 7, 2019 |

How to Become a Blockchain Developer

Skilled blockchain developers are a scarce commodity, as precious as the bitcoins that reside on the distributed ledgers they maintain. Teach yourself one of the major blockchain programming languages and you’ll be set for life, though like anything worth having, this achievement won’t come easy. If you’re contemplating becoming a blockchain dev, here’s how to get started.

Learn Your Languages and Know Your Code

The crypto community is comprised of a series of tribes, each fiercely loyal to its anointed coin. Become a blockchain developer, however, and you’ll be able to transcend these artificial boundaries, because good code is good code, and if you can create bug-proof smart contracts and weed out vulnerabilities, you’ll never find yourself out of a job. Satoshi wrote Bitcoin in C++ and it remains one of the most popular and versatile blockchain programming languages to this day. Java, Python, Ruby, Rust, Solidity, Go, and C# are all to be found within the cryptosphere, however, anchoring crypto networks at the base layer.

How to Become a Blockchain Developer

If you’re intent on becoming a blockchain developer, but don’t know a compiler from a smart contract, a good place to start is by attending a hackathon. Cryptocurrency projects regularly hold these events to encourage developers to build upon their ecosystem and to inspire new use cases and applications. Aeternity’s Big Bang Event, scheduled to take place in Prague on September 20-21, for instance, will bring together 500 participants including developers, entrepreneurs, students, and big tech minds to discuss scaling solutions. Events such as these provide an ideal opportunity to meet like-minded souls and to pick up tips on how to enter the industry.

As Aeternity Crypto Foundation member Emin Mahrt observed, “Everyone is absolutely welcome to attend … We’d be very delighted to meet as many like-minded tech builders and curious dreamers as possible. You never know which of the people you meet will someday become the founder of an industry-breaking product.” Hackathons are a great place for emerging devs, aspiring devs and potential devs who are mooting the wisdom of becoming a full-time blockchain engineer.

The Pros and Cons of Formal Education

Do you have a degree? If you could go back in time, would you swap it for a more useful one – like Computer Science? Or would you ditch it altogether to be free of your student loan and to spend your time doing something more productive? Today, many would-be students are questioning the wisdom of a formal education in an age where you can obtain the same learning for free from Youtube. While there are some fields, such as the social sciences, where academic learning presents the best route to career advancement, that’s not necessarily the case with tech. If you can code, no one cares where you acquired your skills. A prestigious alma mater means nothing when there’s debugging to be done and the clock is ticking.

While the wisdom of pursuing tertiary education is a matter for you to ponder, it’s worth noting that there are now university courses based around blockchain. These include Blockchain at Berkeley – a student-run organization that offers courses on and off campus – and Princeton’s Bitcoin and Cryptocurrency Technologies online course, which has attracted several hundred thousand signups to date. It’s free, but it’s also just 18 hours and – spoiler alert – becoming an expert blockchain developer takes longer than a weekend.

How to Become a Blockchain Developer
Princeton University

University may not be the fastest way to become a blockchain dev, but it shouldn’t be discounted altogether. Besides, there’s more than one way to use educational institutions as a springboard to a job in the cryptosphere. Yannis Stamelakos is a blockchain engineer at Tokencard. “I started my career in academia, doing research on embedded systems which led me to obtain a PhD in computer architecture, focusing on near-threshold computing for low-power manycore systems,” he told news.Bitcoin.com. “I was always fascinated by blockchain technology and so hardware wallets were the perfect entry point.”

From there, Stamelakos gained work with Provable, writing apps for Ledger’s Nano S, generating authenticity proofs that could be validated on-chain. “We were actually working on creating an ideal infrastructure for building oracles that could fetch data to the blockchain in a trustless way. This served as a perfect stepping stone for my role at TokenCard as a Blockchain Engineer,” he finished.

How to Become a Self-Taught Blockchain Developer

For autodidacts, going it alone is the best way to learn the ropes and then master them. If you’ve got the discipline to study and the willpower to avoid firing up crypto Twitter every time your concentration lapses, you’ll find the web to be awash with all the tools and tutorials it takes to become an accomplished cryptocurrency developer. Bitcoin dev Jameson Lopp’s resources page is rich in links to portals for genning up on BTC tech. Udemy’s video courses are also well worth checking out.

How to Become a Blockchain Developer

While there are ideological differences between Bitcoin Core and Bitcoin Cash, from an architectural perspective the two cryptocurrencies are very similar. Thus, the skills you learn from BTC-oriented sites are equally applicable to BCH. For BCH proponents, this knowledge can then be augmented by heading to the developer section of Bitcoin.com. The Learn section is the best place to start. Here, you’ll find step by step instructions on how to build Bitcoin Cash apps from scratch and can view real world examples that can be deployed as your own working copies from which to bootstrap your project. You’ll also find Mastering Bitcoin Cash, based on the acclaimed Mastering Bitcoin by Andreas M. Antonopoulos.

In the future, we’ll all be replaced by robots and AI, but in the here and now, there’s a demand for skilled humans to maintain the current generation of crypto networks and to create new applications and layered solutions built upon decentralized technologies. If that’s you, stop dreaming and start studying.

Meet the Developer Who Added Schnorr Signatures to Bcash

June 14, 2019 |

Meet the Developer Who Added Schnorr Signatures to Bcash

This week news.Bitcoin.com spoke with Jonathan Gonzalez, the blockchain developer who is currently maintaining the Bcash project, a Bitcoin Cash full node written in node.js. Gonzalez explained how he got into Bitcoin Cash development and how he managed to get the Bcash node fully compatible with last May’s fork, which introduced Schnorr signatures to the main chain.

Schnorr Signatures and Bcash

The Bitcoin Cash (BCH) network has a variety of full node implementations that are developed by different programmers. BCH nodes include implementations such as Bitcoin ABC, Unlimited, and Bchd. Last year in May, Purse.io launched an alternative Bitcoin Cash client called Bcash, a BCH protocol node written in node.js. The implementation of the BCH protocol written in node.js can operate as a full node as well as perform Simplified Payment Verification (SPV). Furthermore, it is composed of a wallet backend with BIP44 derivation, a general purpose BCH library, and a mining backend. However, just before the May 2019 upgrade, which added Segwit recovery and Schnorr signatures, Purse announced that they couldn’t maintain the Bcash repository anymore and hoped someone could take over the project.

Meet the Developer Who Added Schnorr Signatures to Bcash
Bcash was introduced to the BCH community in the spring of 2018 and was initially developed by Purse.io.

So Jonathan Gonzalez did just that and all by himself managed to prepare Bcash so it would be fully compatible with the recent upgrade changes. Gonzalez spoke with news.Bitcoin.com this week about how he got into blockchain development, more specifically why he decided to work with BCH, and why he decided to run with the Bcash project.

News.Bitcoin.com (BC): When did you get into developing and how did that gravitate to the cryptocurrency realm?

Jonathan Gonzalez (JG): Early 2016 is when I actually started to write software in a programming language called Clojure. Oddly enough my attention diverted solely towards Bitcoin by way of the Bcoin codebase. I was inspired by the project in the sense that it was an opportunity to actually learn the protocol or design of the system since it was the only structured implementation of the Bitcoin Protocol that I understood.

BC: Why did you decide to work on Bitcoin Cash over another chain?

JG: [This occurred] during the time that I was building a foundation for myself in building out infrastructure projects and learning the Bcoin codebase in 2017. I had no idea about the Bitcoin hard fork up until the 3rd of August when I caught word of it while visiting Purse.io at their office. A month had passed since the visit and there was a big demand for an alternative implementation of the BCH protocol since during that time, there was practically none. Then later, companies like Bitpay, Purse started pursuing using BCH in their businesses. Perhaps the overall decision was circumstantial, nevertheless, I was inspired by the ambition to understand the protocol.

Like all new interests I develop over time, regardless if it’s lucrative or not, I try to the best of my ability to materialize them objectively and till now … [it’s] one of the reasons as to why I always find my way back into BCH.

Meet the Developer Who Added Schnorr Signatures to Bcash
Jonathan Gonzalez is currently maintaining the Bcash repo and has made it compatible with the last upgrade.

BC: You managed to get the Bcash full node implementation up and running after Purse had dropped the project — what made you decide to do that?

JG: I’d accredit that to my pride more than anything. Besides, I use the full node for its API in two services that I utilize daily. I wanted to make sure that if the project were to be disbanded it wouldn’t be due to my lack of interest or efforts.

BC: How did you get the Bcash full node to be compatible with the Schnorr signatures and Segwit recovery upgrade?

JG: The cryptographic library (bcrypto) that Bcash/Bcoin depends on under the hood ported the Schnorr algorithm into the ECDSA/Secp256k1 modules found in the library. Allowing signing and verification functions to be utilized with the Secp256k1 curve. Since there were only modifications to two of the opcodes found in the scripting system (OP_CHECKSIG and OP_CHECKDATASIG), there was no heavy lifting in modifying the stack since there was no change in the transaction portion of the codebase.

Meet the Developer Who Added Schnorr Signatures to Bcash
The open source Bcash full node code and documentation can be found here on Github.

So from there the only requirements for implementing the changes directly involved adding a few additional helper functions to the scripting system that allows the script to distinguish between DER/Schnorr encoded signatures by checking if the Schnorr flag value is set, along with determining whether or not the signature is 64 bytes, since DER and Schnorr differentiate in signature lengths (usually by 6 – 7 bytes).

Now in regards to Segwit recovery, I’ve added a few rules to the input, output script verification which detects whether a witness program is present. Since it’s simply just a recovery mechanism there are no modifications to the SIG_HASHTYPES. Nothing realistically changed in the signature hash so it simply looks for the redeem script to be a witness program and the regular witness program logic was ported from Bcoin. I’d say [Segwit recovery] was the easiest out of the two things to implement for the hard fork spec.

BC: Why do you think Bcash is a worthy node to build over other implementations?

JG: There are tons of interesting features that come along with the design of the codebase. For instance, the wallet is completely segregated from the full node and lives on its own node port. Something that Bitcoin Core hasn’t accomplished yet. Building APIs around the full node and wallet nodes are very simple to get up and running. The documentation found in the docs section of the project is also very descriptive and since it’s Javascript, running a REPL and testing out the libraries in the project makes it easy to understand and create new data structures for anything general purpose. This includes things such as creating scripts/transactions and running a regtest node in REPL. Features such as Neutrino, address/TX indexing have been backported into the full node library as well.

I’d also like to note that the code style found in the project is very clean and easy to understand. These are some things that off the top of my head I’m able to pitch to any developers out there seeking to build out infrastructure, or simply desiring to learn the protocol.

Maintaining the Bcash Repository, and Possibly Adding Future Enhancements Like Merkelix and Avalanche

BC: Do you aim to keep maintaining the Bcash repo?

JG: I do plan on continuing to maintain the project by adding additional protocol proposals to the codebase, along with porting over future hard fork specifications. I’ve recently taken an interest in adding a Schnorr multi-sig proposal branch to the node as well. I’ve been really interested in proposals such as Merkelix and Avalanche so I plan on finishing these features. Maintaining the full node allows me to experiment freely with actual motivation.

BC: Is anyone helping you?

JG: No, no one is currently helping in maintaining, nor downstreaming patches from Bcoin to the project.

I do plan on being involved in more developer meetups showcasing the codebase by demonstrating how simple and easy it is to use the full node for infrastructure projects or general purposes.

Meet the Developer Who Added Schnorr Signatures to Bcash
Bcash includes Schnorr signatures compatible with the current BCH network, Libsecp256k1, an advanced API, Compact Blocks, BIP151, BIP150, and a JSON RPC API.

BC: How do you feel about the current state of Bitcoin Cash (BCH) right now as far as the community and development is concerned?

JG: I’m not sure what to think of the community, but from my impression, I believe there’s definitely support in the developer realm, which otherwise would be nonexistent in Bitcoin. Although I’m not entirely familiar with the things that go on throughout social media, forums regarding BCH. I’m a bit of a loner and don’t have an interest in these sorts of things.

But in regard to development, the greatest facet of Bitcoin Cash is the scheduled six-month hard fork activations. It allows for BIPS/features to be considered as long as there exists a motive, a reason behind the proposals which is, in my opinion, is very innovative and worth paying attention to.

What do you think about Jonathan Gonzalez managing to get Bcash compatible with the last upgrade and maintaining the Bcash project? Let us know what you think about this subject in the comments section below.

Developer Creates Interwallet Transfer Plugin to Strengthen Bitcoin Cash Privacy

The Bitcoin Cash (BCH) protocol and infrastructure continue to see relentless development. The Electron Cash Cashshuffle implementation has enhanced bitcoin cash fungibility by providing users with the ability to shuffle coins. Now a developer has announced the launch of the Interwallet transfer tool, an Electron Cash add-on that allows for privacy-minded transfers using the light client.

Interwallet Transfer Increases Bitcoin Cash Fungibility

This week, software engineer Karol Trzeszczkowski announced the launch of a new plugin called the Interwallet Transfer. The tool works with the Electron Cash (EC) wallet and allows individuals to transfer funds from one wallet to another without compromising anonymity after using tools like Cashshuffle. Trzeszczkowski revealed the EC plugin on May 17 and thanked the developers Emergent Reasons, John Moriarty, and Calin Culianu (Nilac the grim) for help with the review process.

“[Interwallet Transfer] is a simple plugin that allows you to specify a destination wallet (represented by its xpub extended public key), and transfer coins from the source wallet to destination one-at-a-time at random intervals,” Trzeszczkowski said during the launch announcement. “Compared to the simplistic method of transferring everything in one big transaction, this method preserves privacy to a much higher degree: no longer are all your coins linked in that one transaction.”

Developer Creates Interwallet Transfer Plugin to Strengthen Bitcoin Cash Privacy

The Interwallet Transfer is open source and located on Github, while the project’s documentation details how the add-on works and how to install the plugin. The platform sends your coins to unused addresses from another wallet at random times over a selected time period and these coins are sent in one-in-one-out transactions. In order to install the platform, download the latest Interwallet Transfer and you can verify the integrity of the software using Trzeszczkowski’s public key. After the download is complete, you can open the wallet and click the Tools section from the drop-down menu. From here simply click Installed Plugins and press Add Plugin which will prompt a warning and the install window. After these steps are complete, the Interwallet Transfer add-on will be available to process transfers.

Transfer Shuffled BCH at Randomly Selected Intervals

The Github documentation also teaches people how to transfer using the newly added plugin. In order to get started, simply paste the receiving wallet’s Master Public Key in the first dialogue box in the plugin tab. At this point, simply enter the amount of time you want the randomized transfers to take. “Within that amount of time, all funds will be transferred to the receiving wallet at randomly selected intervals,” read the Interwallet Transfer Github specifications. Once the process is complete you can press the Transfer tab and the Electron Cash wallet will begin processing the transactions within the set timeframe. The Interwallet Transfer developers note that the wallet must be open and running in order to complete the transfers.

The BCH community was pleased to hear about Trzeszczkowski’s plugin for the EC wallet. “Ok, this might be the first plug-in for Electron Cash I might use — I can also use it to relocate a cold wallet without linking everything,” a BCH supporter stated on the Reddit forum r/btc. Another commenter remarked that “[Interwallet Transfer] makes it much easier to have a shuffle wallet and a separate mobile spending wallet.” Trzeszczkowski is also the creator of the open source Last Will platform, a smart contract program for the inheritance of bitcoin cash.

BCH Developer Builds Onchain Token Auction Console — SLP Agora

April 27, 2019 |

BCH Developer Builds Onchain Token Auction Console — SLP Agora

On April 26, software developer Tobias Ruck revealed a new platform he’s been working on called SLP Agora, an onchain trading console written in Rust that allows users to auction SLP tokens for bitcoin cash. The application’s decision-based transactions are secured by a smart contract technique enabled by the newly implemented opcode OP_Checkdatasig.

SLP Agora Enables Token Auctions Onchain

The Simple Ledger Protocol (SLP), a system that allows token creation on the Bitcoin Cash (BCH) network, has become extremely popular. Lots of people have been creating tokens and some of them are being sold on exchanges and even used by the micronation of Liberland. Now the software engineer Tobias Ruck has released a new SLP application called SLP Agora, a platform that allows for onchain token auctions. The open source platform uses smart contracts to perform the actions using the OP_Checkdatasig opcode that was added to the BCH network last November. According to Ruck, the application is built with the programming language Rust and uses a “nifty trick” outlined by the software developer Tendo Pein.

“SLP Agora is a simple trading platform written in Rust where you can put your favourite tokens up for auction — all on the BCH blockchain,” Ruck explained on Friday.

In addition to the release of the early version of SLP Agora, Ruck also hosted a live stream in order to show other BCH developers and the community how the market works. People can also try SLP Agora out by downloading the EXE files for Windows or build the application on another operating system using the source code. “So far, it’s only an interactive console application (not pretty but easy to use), however, I hope there will be enough interest and support in the community that we’re able to build a nice intuitive web interface and create an extensible protocol,” Ruck remarked.

Revolutionizing Smart Contracts With OP_Checkdatasig

Ruck also warned that there may be a couple of bugs because the application is so new and noted that people should only use small fractions of funds at the moment. The developer also emphasized that even though the project is experimental, in operation it’s proven to be “surprisingly flawless.” Ruck also noted that because of the underlying nature of the Simple Ledger Protocol, users can only place sell orders, but not buy orders. The project’s creator also placed a few sell orders for the “incredibly useful Tobi’s Terrific Trading Token (TTTT)” on the platform so people can test the platform.

Bitcoin cash fans were thrilled to hear about the onchain token auction system.

The opcode OP_Checkdatasig has been heralded by many developers for being able to make the BCH protocol’s Script language more robust. So far the BCH community has witnessed some incredible achievements by developers using OP_Checkdatasig. Just recently, the engineer Karol Trzeszczkowski launched a platform called the Last Will, a smart contract program for the inheritance of bitcoin cash using the opcode. SLP developers recently published the Cashy toolbox which makes use of OP_Checkdatasig.

According to Ruck, the SLP Agora platform saw a lot of users over the last 24 hours.

The upcoming service Bitcoin.com Oracle will be using the benefits of the opcode in order to provide verifiable multi-sourced facts. Last November, Ruck also showcased how the new Bitcoin Cash opcode makes an onchain game of Chess possible. Ruck has continued to build with the OP_Checkdatasig opcode and the BCH community seems pleased with the results.

Wikileaks Cache Now Hosted on IPFS Thanks to this Bitcoin Cash Developer

Wikileaks Cache Now Hosted on IPFS Thanks to this Bitcoin Cash Developer

With the founder of Wikileaks behind bars, it’s been a trying time for activists who believe in spreading freedom and truth in an age steeped in lies and manipulation from parasitic central bankers and bureaucrats. In order to show support for Julian Assange, Bitcoin Cash (BCH) developer Chris Troutner decided to upload the entire Wikileaks cache of documents to the Inter-Planetary File System (IPFS) and the BCH chain so the truth can be read forever.

Truth Is Treason in an Empire of Lies

Since April 11, there’s been a lot of attention directed toward Wikileaks founder Julian Assange. His arrest stems from indictment charges from March 2010 that allege Assange and former U.S. Army intelligence analyst Chelsea Manning cracked the country’s Department of Defense server password. The leaks that were distributed back then caused chaos for politicians and financial elites supporting the military industrial complex because they exposed horrific crimes against humanity. One specific video leaked in 2010 by Wikileaks called Collateral Murder displayed a U.S. helicopter gunning down targeted individuals but they also killed innocent people including children, journalists, and Reuters photographer Namir Noor-Eldeen age 22.

After the trove of documents, files, and videos were released, Wikileaks faced a financial blockade where payment processors like Paypal, Visa, and Mastercard prevented the website from receiving donations. This was when the Bitcoin network came to the rescue and Wikileaks decided to accept the digital currency for donations. Chelsea Manning (then known as Bradley) was charged with treason and sent to Guantanamo Bay. Assange went on the run, faced charges in Sweden for an alleged rape case, and found himself hiding in the Ecuadorian Embassy in the U.K. for the next seven years. Manning was since pardoned by U.S. President Obama before he left office, but was recently arrested for indictment charges against her and Assange. After the April 11 arrest, Assange is now being held in London at the moment and may face charges in Sweden and be extradited to the U.S. as well.

Hosting the Wikileaks Cache of Files on the BCH Chain and IPFS

Lots of Bitcoin proponents have supported Assange and Wikileaks for years for leaking thought-provoking documents without hesitation. Since the arrest three days ago, Wikileaks and Assange have managed to gather $ 41,000 in BTC donations. Another endeavor that took place in order to show support for Wikileaks was when BCH programmer Chris Troutner uploaded the entire Wikileaks cache to the BCH chain and IPFS. This means the 30GB of files can be downloaded and viewed by anyone at any time for as long as the BCH and IPFS networks exist. The website Wikileaks.cash has the entire database which includes documents stemming from the controversial wars in Afghanistan and Iraq, leaked FBI data, Homeland Security papers, Barclay’s tax avoidance, the infamous Bilderberg meeting transcripts, and FEMA reports.

Of course, Wikileaks.cash can be accessed directly but the archive can also be downloaded via torrent software. Troutner has also published step-by-step directions on how to help syndicate the Wikileaks archive over IPFS. Essentially, you need to install IPFS and initialize an IPFS node to get the daemon running. You can optionally connect the IPFS node to the cloud server and download the content, which also helps syndicate it. From there, you can pin the content so the computer will continue to share it. Troutner’s walkthrough is hosted on Memo.cash which is also embedded into the BCH chain.

The bureaucracy today has created an Orwellian nightmare and many have grown worrisome about the removal of financial privacy and seeing whistleblowers being scorned for telling the truth. A system like Bitcoin, with its censorship resistance, yields many benefits that include furthering the dissemination of information the elite would like to stifle. Having the Wikileaks data hosted on the BCH chain and IPFS helps bolster the documents’ preservation and syndication over time. These days, telling the truth truly has become a revolutionary act and bitcoin cash, with the help of the community behind it, is helping to keep that insurrectionary spirit alive.

Developer Launches Mturk Alternative ‘Taskopus’ Powered by Bitcoin Cash

March 12, 2019 |

On March 11, the creators of the Freelanceforcoins platform announced the launch of a new crowdsourcing market called Taskopus. The standalone application is similar to Amazon’s Mechanical Turk marketplace but anyone can participate, payouts are near instantaneous and bitcoin cash (BCH) is used for settlement due to the chain’s low network fees.

Meet Taskopus, the Mturk Alternative

News.Bitcoin.com recently reported on the newly created Freelanceforcoins. This Monday the lead developer of the platform announced a new alternative to Amazon’s Mechanical Turk marketplace (Mturk) called Taskopus. Essentially Taskopus users complete tasks that computers or artificial intelligence cannot accomplish. Users can perform the chores published by task creators and get paid almost instantly in BCH once the buyer is online. Taskopus users can also create assignments, micro-jobs, and exercises for the general public to complete.

The creator of Taskopus explained on Monday that he has approved around 30 people to test the application before the official launch. The testing is a form of pre-launch and the project is still in its earliest beta stage. At the moment the ‘creating tasks’ function is enabled manually on case-by-case basis, but there are small procedures that can be completed like reviewing an advertisement, completing a sentence, finding someone’s contact info, filling out a survey, and extracting keywords.

“There is a big difference between us and other crowdsourcing sites (besides the fact that everybody is accepted, regardless of age, country, and social status( — All payouts are immediate and final and we don’t ever keep your money and with Taskopus you can have a long relationship with a worker,” the platform’s creator emphasized.

The developer continued:

Typical micro-jobs website treats workers as completely interchangeable. Do one simple task if you fit our description and get out — Taskopus is different in that regard — You can build a multi-step selection process for your employees, educate them and give them complex long higher-priced specialized tasks.

BCH Powered Due to Reasonable Network Fees

After downloading the standalone application Taskopus, you will be given a survey to help buyers figure out if you fit their needs. After answering the questions, the Taskopus dashboard shows a home section, tasks, your profile’s survey answers, a profile, and a native wallet. The wallet is fairly basic and allows users to write down a 12-word seed phrase and send and receive BCH. After completing a few easy online errands on my task page I earned a small fraction of BCH (0.00211649). Of course, with only 30-odd testers and the developer creating experimental tasks, the platform will definitely need a decent sized community of members to keep the marketplace going strong. If the marketplace gathers a lot of attention in the future, it could very well outpace crowdsourcing services like Mturk with Taskopus’s accessibility and acceptance of anyone and everyone. The creator of Taskopus says there are big differences between the BCH-powered app and other crowdsourcing operations.

“There is one more big difference as we are also data-driven, and if you want to understand it – you can go here and read an example about classifying cities,” the Taskopus creator explained on r/btc. “And there is more — We have Javascript validation tasks, we have limits (daily, hourly), we have automated invoice payments for when you are offline, we have a REST API, Webhooks, aggregated Webhooks, profile questions, and targeting of tasks to users.”

BCH supporters have welcomed an alternative to Mturk and other crowdsourcing sites. Using BCH in order to facilitate payments is a plus and the Taskopus creator specifically chose to use BCH over BTC. “We needed a cryptocurrency that can split $ 0.01 into 90% and 10%, send 90% to the worker and 10% to us as a commission and do all of that with a reasonable fee (less than the amount being sent),” the Taskopus founder explained.
