SALT Enables Traditional Lending Secured by Cryptocurrency

SALT Enables Traditional Lending Secured by Cryptocurrency

A new startup in Denver, Colorado has set out to take on the blockchain-based lending market. Secured Automated Lending Technology, or SALT for short, is a membership-based financial enterprise with its eyes set on being recognized as the first lending platform to facilitate loans collateralized by bitcoin and other cryptocurrencies.

Touted as “traditional lending secured by cryptocurrency,” SALT will allow members to leverage assets like bitcoin and ether for loan collateral. This new platform, which will be tethered to Ethereum ERC20 smart contracts, will enable borrowers to tap into “capital on demand” via its ecosystem of lenders. The major value proposition is that it provides a mechanism for supporting the value of investor holdings, while simplifying all aspects of the loan process and leveraging the power of a blockchain-centric lending market.

The following scenario illustrates a typical use case for SALT: imagine if you sold out your entire bitcoin holdings in 2016 for a luxury purchase, only to see the price shoot to the moon in 2017, resulting in a loss of all that you might have gained over the course of that period had you held on to your bitcoins.

With SALT, an investor who has collateral they wish to retain can leverage their crypto-assets for a loan. This allows them to maintain a long position with their assets while creating a greater set of options with their taxes.

The SALT loan process consists of four primary steps:

  1. Loan Creation: a borrower sets up a membership account and then forwards their collateral to the SALT Oracle Wallet. This is a multi-signature blockchain wallet that functions as a repository for collateral while automatically managing the lending terms.

  2. The loan funds, once approved, are transferred to the borrower’s bank account.

  3. Loan Repayment: a borrower makes timely, periodic payments to the lender.

  4. Loan Completion: upon repayment of the loan, the borrower will have their collateral returned.

SALT doesn’t perform credit checks on borrowers but does conduct full Anti-money Laundering (AML) and Know Your Customer (KYC) verification checks. Loans made via the platform are denominated in and repaid with traditional currencies.

Cryptocurrency assets are used only by the recipient as collateral for the loans. Borrowers can choose to pay off their loans early without being subjected to a prepayment penalty.

SALT members are not required to possess blockchain assets in order to lend on the platform. Lenders must be accredited investors in accordance with federal regulations and guidelines established by the U.S. Securities and Exchange Commission. They must also pass SALT’s Lending Suitability Test.

At the time of the company’s soft launch, Shawn Owen, CEO of SALT, told Bitcoin Magazine, “Currently, if you are a holder of blockchain assets, a large chunk of your financial wealth is not being recognized by lenders. With SALT, we see a future where virtually all of the world’s value is on blockchains, with lending reflective of our globally connected, digitized lives.”

Owen says he left his full-time job in 2016, intrigued by the idea of a lending platform that could leverage billions of dollars of untapped cryptocurrencies. “I saw this trend where the vast majority of Bitcoiners just wanted to hold on to their assets. With this realization, the light bulbs all went off, which prompted me to go full blast with SALT. I haven’t really looked back since.”  

When asked about how he came up with name SALT, Owen has this to say: “We liked the name because ‘salt’ was historically the first well-known commodity-based money. Our version of SALT is a way to articulate what we do: taking blockchain technology and smart contracts and building lending terms and everything revolving around credit products and putting them into smart contracts in a more automatic and secure way.”

Owen says many in the Bitcoin community have at one point or another experienced a situation where they have sold because they felt that they had a good gain, only to look back and realize that they had missed a massive opportunity. And in that sale, notes Owen, they most likely had to worry about capital gains tax counting and were now wishing they could go back in time six months and have all that ether or bitcoin back.

In terms of emerging trends in the blockchain lending space, Owen points to the massive growth in the number of cryptocurrencies coming online and the innovation associated with them. He says that although it will be a bumpy ride, he believes we’ll continue to see more and more of the world’s value accounted for on distributed ledgers and on blockchains.

“I see a world where large portfolios will be made up of digital assets and they will be much more granular abilities to lend against these portfolios in a much higher liquid form than what we have today. This, I am certain, will solve a lot of the liquidity inefficiencies in the market.”  

Though SALT is currently operating only in the U.S., Owen anticipates making a quick move into Ireland, followed most likely by Canada. “The big picture we are striving for is to create the mechanisms with which lending terms of any type, between any person or individual, whether it be business or not, can interact in a peer-to-peer way with contracts that are enforceable without counterparty risk.”

Erik Voorhees, founder and CEO of ShapeShift and a member of SALT’s board of directors, commented, “SALT’s disruptive innovation is an important project for broadening the usefulness and global reach of blockchain technology.”

Bcoin Protocol Gets Major Development Funding With New Agreement

Purse Introduces New Bcoin Protocol Agreement

Purse has announced a new agreement with Bitmain Technologies, F2Pool, Bitcoin.com and Bixin that will allocate millions of dollars to its bcoin protocol development.

When working with Bitcoin, decentralization is king. Purse CEO Andrew Lee, through bcoin, extends that logic to the Bitcoin protocol itself.

“For Bitcoin to take off, we need multiple implementations with even market share,” Lee explains in a Medium post. “Decentralizing protocol development will lead to multiple clients, diverse communities, more developers, better security and more innovation.”

So what is bcoin? Put simply, Bitcoin was written in C++ coding language, which has a steep learning curve and remains a bit out of reach for many developers. Bcoin helps to solve that problem by re-implementing Bitcoin in Javascript, arguably a more widely used language. This opens the door for more innovation in Bitcoin because more developers will be able to create apps and protocol improvements in Javascript instead of the more complex C++. In October of 2016, Purse announced that it would be running its online market service on top of bcoin.

An important feature of this new agreement is that the participants will gain no equity in any of the projects that arise from the funding. “Bitmain, Bitcoin.com, Bixin and F2Pool donated funds for a non-equity stake to specifically help with supporting the development of multiple implementations. Similar companies also donated to Parity (who is working on a Rust implementation of Bitcoin). The more client diversity Bitcoin has, the better,” explained Steven McKie, head of Growth & Product Content at Purse, in correspondence with Bitcoin Magazine. “Bcoin remains an independent project.”

As for how the funding will be allocated, McKie explains, “The funding will help directly with onboarding and training new developers to commit to the bcoin full-node implementation, open-source project.”

The timing of this announcement is important as it comes almost immediately after the announcement of the 2MBHF + SegWitSF agreement. According to McKie, “Bcoin will work to implement support for the 2MBHF + SegWitSF proposal into the codebase as we stated in our support for the proposal.” This funding agreement will go a long way toward helping that initiative.

“Bcoin is built for modularity and for developers to quickly be able to start utilizing Bitcoin’s robust global network and start hacking together useful tools and applications. Our full node is built on a stack that is attractive to as many developers as possible (node.js). Bcoin has support for all of Bitcoin’s latest features; it’s secure and production-tested by companies like Purse, BitPay, Bixin, Ripio and Bitwala — with more to come.”

Social Messaging App Kik Will Bring Crypto Tokens to Teen Market

Social Messaging App Kik Will Bring Crypto Tokens to Teen Market

Chat platform Kik has revealed that it is launching its Kin token that will deliver the basis for a decentralized ecosystem of digital services.

Ontario-based chat platform Kik, which has over 300 million active users registered worldwide, including around 40 percent of American teens, has announced today that it is launching its Kin token, a digital currency that will provide a foundation for a decentralized ecosystem of digital services.

Today's technology has meant that it is impossible not to stay connected with friends and family worldwide with many using messaging apps to do so.

So much so, that by 2019 more than one-quarter of the world's 7.5 billion population will be using messaging apps, according to data from eMarketer.

Aside from being a cheaper alternative to SMS and MMS, messaging apps are big business that offer a slew of functions: group chats, gaming, GIFs, videos, stickers, emojis, photos and in-built web pages. Not only that, but a majority of messaging apps users are young, which is an extremely important demographic for messaging apps.

Kik believes that through its token it can bring together the areas of communications, information and commerce in a new way that will fuel how today's generation and future ones will connect. Founded in 2009, Kik was the first chat app that went viral in 2010 from zero to one million users in 15 days. Since then the company has continued to meet the innovation space by becoming the first chat app to become a platform in 2011 before establishing itself as the first app within the Western world to add bots in 2014. Now, Kik is the first chat app to add its own digital currency.

Speaking to Bitcoin Magazine, Ted Livingston, Kik's CEO said that the main motivation for launching their Kin token, which comes from the word “kinship,” came down to two main insights: digital services, which are becoming more important to our daily lives, and the fact that these services are being owned and controlled by fewer and fewer companies. This, in turn, is bringing about less innovation and choice. According to Livingston, this centralization is the result of both economics and competition.

"From an economic side, it's very hard for independent developers, including companies as big as Kik, to monetize," he said. "There are a few companies that have huge scale that use that scale to monetize their advertising."

Livingston adds that, when these bigger companies monetize their advertising, they then give everything else away for free. This means that for independent digital services who don't bring in enough money through advertising, they live in a world where these giants have set the expectations where everything should be free.

"As a result, it's very hard for all these digital services to monetize," Livingston adds. "Those that do, these giants then turn to a copy-and-crush strategy where they take all the ideas from the players, copy it and use their much larger resources to crush the other competitors who do make it."

As a result, Livingston states that now is the right time to put forward an alternative ecosystem of digital services that isn't just open, but through digital currencies and decentralization, better. By launching their Kin token, Kik is attempting to set up a new economic system that can monetize digital services and deliver a new way to compete together with the larger companies.

The Kin Token and the Kin Foundation

Through the advanced developments in digital currencies and the blockchain, Kik is planning on creating a decentralized ecosystem of digital services through four steps: creating the Kin token on Ethereum, integrating Kin into Kik, developing the Kin Rewards Engine and launching the Kin Foundation.

Implemented on the Ethereum blockchain as an ERC20 token, Kin will serve as the basis of interoperability for all transactions within the Kin ecosystem. By adopting the token within the Kik app, it's hoped that millions of users will facilitate widespread adoption of Kin, establishing demand and value for the cryptocurrency. In preparation for the eventual launch of Kin, Kik has been experimenting with the integration of a cryptocurrency on its platform since 2014.

"In 2014, we launched an experiment called Kik Coins and the question we were trying to answer was: Could we get millions of everyday consumers earning and spending natively in a digital currency?" Livingston said. "The result is that we created a transaction volume that was three times better than Bitcoin's global transaction volume at the time."

Kik also realized that the best way for consumers to understand cryptocurrency was for them to earn it through digital services like Kik.

"The biggest flaw with all the other cryptocurrencies is that nobody gets their paycheck in that cryptocurrency; the only way to get it is to buy it, for 99.99 percent of people," he added. "This is where teenagers are another big asset for Kik in that they don't have a ton of spending power and this is a way to earn that spending power by offering value inside the community itself."

Over time, Livingston explained, there will be various ways that users can earn Kin. One of the examples he gives is through exclusive group chats by charging an entrance fee with Kin to then spend within the Kik ecosystem.

Kin Distribution

Kik is planning on starting a crowdsale where the amount of Kin tokens available will be $1 trillion. However, the majority of the Kin will be set aside to form the Kin Rewards Engine. Modelled similarly to the Bitcoin mining system, the Kin Rewards Engine will release a certain amount of Kin every so often to all the developers that build digital services within the ecosystem.

"Every day there will be a daily reward, which we think will start roughly at $100,000 per day," he said. "As an owner of a service, if you integrate Kin and get people transacting Kin inside your digital service, which generates 10 percent of all transactions within the ecosystem, that would entitle you to 10 percent of this daily reward."

Ultimately, the more services that join the Kin ecosystem computes to more transactions that happen each day, which increases Kin's value on public exchanges and, in turn, boosts the daily reward.

"It creates this amazing network effect where all these digital services work together to grow the overall value of the ecosystem," Livingston adds. "They all get a fair and equitable piece of that economic value they create, and consumers get this ecosystem of services that continues to grow in both size and quality."

According to Livingston, one of the most underappreciated values of digital currencies is how much economic opportunity they can produce. For instance, he said even though they are giving away $100,000 per day, the amount of Kin available won't run out anytime soon.

"If Ethereum was giving out $100,000 of Ether a day at its current $10 billion market cap, it would take them 273 years to give away all the Ether," he said. "If Bitcoin was doing it at their $30 billion market cap, they could give away $300,000 a day for 273 years, and these are both cryptocurrencies not used by mainstream consumers."

As such Livingston believes that the Kin reward could easily go to $200,000, $500,000, even $1 million a day, incentivizing the creation of an open and compelling ecosystem of digital services for consumers.

Through the Kin Foundation, the team are ultimately trying to achieve a decentralized system where the developer doesn't need to trust the Kin Foundation. As a nonprofit, the foundation will oversee the open and fair growth of the system where it will provide three things: it will administer the rewards system, it will offer an identity service for users to move between the digital services and it will provide a transaction service for users to earn and spend Kin in a secure and frictionless way, Livingston states.  

Kik is due to release their whitepaper today, at which point they expect to start working with the crypto community, which will lead to their crowdsale in the next few months.

Hyperledger Moves Blockchain Frameworks Sawtooth and Iroha Forward, Adds Members

Hyperledger Moves Blockchain Frameworks Sawtooth and Iroha to Active Status

Hyperledger, the open-source, cross-industry collaborative effort focusing on blockchain technology, has advanced the status of its Sawtooth and Iroha blockchain frameworks from “Incubation” to “Active” status.

The green light was given by Hyperledger’s 12-member Technical Steering Committee (TSC), chaired by Christopher Ferris, CTO of Open Technology at IBM. It followed an extensive review period during which each project was evaluated based on exit criteria that include legal compliance, community support, test coverage and continuous integration support, documentation, code reviews and more.

Ray George, senior director of PR at the Linux Foundation, told Bitcoin Magazine that “there is no difference [between Incubation and Active status] when it comes to how the projects are expected to run and how the TSC works with them to ensure a healthy community continues to be built.

“The most tangible difference is how this is presented to the public — not as projects whose communities are still finding their bearings, but as communities ready for new contributors and whose users can depend upon those communities persisting for the long term.”

Hyperledger Iroha, which was initially proposed by Soramitsu, Hitachi, NTT DATA and Colu, is a business blockchain framework inspired by Hyperledger Fabric. It was designed to be simple and easy to incorporate into infrastructural projects requiring distributed ledger technology, and aims to provide a development environment where C++, web and mobile application developers can contribute to the Hyperledger Project.

Hyperledger Sawtooth was initially contributed by Intel and designed to explore scalability, security and privacy questions prompted by the original distributed ledgers.

The modular platform allows organizations to build, deploy and run complex distributed ledgers, and includes a novel consensus algorithm, Proof of Elapsed Time (PoET), which targets large distributed validator populations with minimal resource consumption.

Sawtooth and Iroha follow Hyperledger Fabric, the first project to graduate in March 2017. These projects, alongside five others, all fall under the Hyperledger organization umbrella, which focuses on bringing together software developer communities to develop open-source blockchain and smart contract related technologies.

Projects currently in Incubation include Hyperledger Cello, a blockchain module toolkit; Hyperledger Composer, a set of collaboration tools for building blockchain business networks; and Hyperledger Explorer, a blockchain explorer for viewing, invoking, deploying or querying blocks, transactions and associated data.

Hyperledger’s Membership Expands

The news of Sawtooth and Iroha moving out of Incubation broke on Monday at Consensus 2017, a major blockchain-focused event taking place this week in New York, during which Hyperledger also announced the addition of eight new members, bringing its total membership to 142.

New members joining the Hyperledger Project include Deloitte, Ernst & Young, Schroder Investment Management, AlphaPoint and Change Healthcare, one of America’s largest healthcare IT companies and the first healthcare organization to join at the top membership level.

Change Healthcare’s CTO, Aaron Symanski, will be joining the Hyperledger Governing Board, chaired by Blythe Masters, CEO of Digital Asset, and consisting of representatives from 20 members of the Hyperledger membership.

“Blockchain [technology] is a promising and exciting new technology for secure online transactions,” said Symanski. “But it is crucial that healthcare leaders step up to champion innovation to help take blockchain [technology] from its early implementations to tomorrow’s healthcare IT solutions.”

In October 2016, Hyperledger kicked off a Healthcare Working Group to advance blockchain development in the healthcare industry. The group now has more than 425 technologists and executives representing the likes of Accenture, Gem, Hashed Health and IBM.

Another company that has joined the Hyperledger Project is FZG360 Network Co. Ltd., a leading real-estate portal and trading platform in China, which aims to “enhance the application of [blockchain technology] to a higher maturity level,” particularly in the area of real estate.

Hyperledger was founded in December 2015 by the Linux Foundation and counts among its members leading firms representing various industries including blockchain technology, finance, healthcare, the Internet of Things, aeronautics and real estate, among several others.

Qtum’s Block Size Limit Will Be Governed by Smart Contracts: Here’s How

Qtum’s Block Size Limit Will Be Governed by Smart Contracts: Here’s How

Qtum is an up-and-coming smart contract platform set to launch in September of this year. Sometimes ambitiously referring to itself as “China’s Ethereum,” the project recently raised $15 million in three days through a successful crowdsale or “Initial Coin Offering” (ICO).

On a technical level, the Qtum blockchain will resemble Bitcoin, but will integrate an Ethereum-like Virtual Machine on top for smart contracting purposes. Additionally, Qtum is in the process of implementing a “Decentralized Governance Protocol” (DGP). This DGP will have smart contracts determine the blockchain’s parameter selection, like its block size limit.

Jordan Earls, also known as “earlz” online, is the co-founder and lead developer of Qtum.

“We believe this will allow for Qtum to be the first self-modifiable, self-regulating and ultimately self-aware blockchain,” he told Bitcoin Magazine.

 The Concept

Any blockchain has a number of parameters. In Bitcoin, this of course includes the 1 megabyte block size limit. But it also includes the block reward (currently 12.5), the block interval time (ten minutes) and more. These and three other parameters apply to Qtum as well.

But there are two basic problems with needing to have these parameters. First, they are very hard to get “right,” in so far as that’s even possible, since different parameters benefit different use cases. And second, in a decentralized system, these parameters can be very hard to change.

“The core rationale and problem we had when designing this is that we will release Qtum with some initial parameters that we try to make perfect,” Earls told Bitcoin Magazine. “But we don't know what the ecosystem will look like one month after release, much less one year. So, we designed DGP. That way, we can tune the blockchain to be as usable and secure as possible without needing to fork, just to change a simple number from 1 to 2.”

Qtum plans to realize this way of “tuning the blockchain” by doing what it does best: The DGP will consist of relatively straightforward smart contracts made up of blockchain-readable pieces of executable code.

“We have open-source smart contracts which implement the rules for changing the parameters, which will then be accepted by all nodes. It implements a fairly simple governance system of ‘user keys’ and ‘admin keys.’ There is a modifiable parameter in the contract which determines how many keys of each type must vote in order to approve a change to, say, the block size limit.”

Importantly, through the use of smart contracts, these keys can actually represent more than just a regular user per key: Each key can represent a defined group.

“Perhaps one key represents a majority of hash power; or a key represents coin votes by coin holders; or a key acts according to a dynamic limit based on how full blocks are. Or even oracles: a key can effectively be controlled by people or servers that act based on input not directly readable by the blockchain itself, like USD market price for transaction fees. It’s extremely flexible.”

Qtum will almost certainly include smart contracts for the block size limit, the gas schedule to determine the price of different smart contract operations (for which Ethereum hard forked several times) and the minimum gas price. Additionally, it might deploy smart contracts for block interval times, block rewards, maximum gas per block and maximum script size or signature operations per transaction or block.

Changing the Rules

Embedding the parameter selection in smart contracts is clever and having all node software adjust accordingly even more so. However, an arguably even harder problem is not so much what parameter is decided on, but who gets to decide in the first place and how.

In Qtum, the initial parameters will be set by the developers based on their testing and measurements.

“For instance, we've already determined that a block size of 2 megabytes should be reasonable,” Earls said.

After that, the initial set of rules to define the parameters can be changed themselves within the rules of the system, too.

A smart contract could, for example, start out relatively simple: It requires a majority of core developers to change the rules of the contract. Then, if a majority of core developers decides that instead of just developers, it should also include a majority of coin holders, the contract can be changed to a two-of-two multisig contract. From that moment on, one key would represent the developers, while the other key would represent the majority of coin holders. Next, if both developers and coin holders agree, hash power can have a seat at the table, too, and so forth.

As such, Qtum smart contracts can change not only the parameters of the system, but also how the parameters themselves can be changed.

That said, as Earls acknowledged, the Decentralized Governance Protocol can’t actually solve all governance problems. It’s specifically designed to make certain predefined parameters more easily adjustable, and it can indeed even change how these parameters can be adjusted to some extent.

But the Decentralized Governance Protocol does not and cannot apply to network rules that aren’t among these predefined parameters. Protocol changes outside of these specific parameters would still require a typical upgrade mechanism, like a hard fork or a soft fork.

“I believe if Bitcoin had DGP technology, then we would still see all this fighting about SegWit vs Bitcoin Unlimited, etcetera,” Earls acknowledged. “But, DGP would have been used in the meantime to increase the block size to something conservative but reasonable like 2 megabytes or 4 megabytes, to avoid all the transaction speed problems. Meanwhile, the developers and community could figure out a more permanent solution.”

DCG’s Bitcoin Scaling Proposal and What it Needs to Succeed

DCG’s Scaling Proposal and What it Needs to Succeed

Spearheaded by Barry Silbert’s Digital Currency Group (DCG), over 50 companies signed and published on Medium a “Bitcoin Scaling Agreement” this week. The agreement intends to put an end to Bitcoin’s long-lasting scaling debate. But whether it actually will is a different question.

Here’s what the agreement entails, how it compares to existing scaling proposals and what it requires to succeed …

What the Agreement Entails

The DCG agreement is based on the “SegWit2MB” proposal, originally floated by RSK Founder and Chief Scientist Sergio Demian Lerner. This proposal couples activation of Segregated Witness (SegWit), the centrepiece of Bitcoin Core’s scaling roadmap, with an added block-size-increase hard fork down the road. While SegWit itself offers an increase to two to four megabytes, the added hard fork should double this to a maximum of eight megabytes.

According to the Medium post, the soft fork will be activated “at an 80% threshold,” (presumably) referring to hash power. And the hard fork will be activated “within six months.”

However, it seems that different signatories have different interpretations of what this actually means. Some claim that SegWit will be activated as a soft fork first, followed by a separate block-size-increase hard fork later. Others suggest that the soft fork will come first, but in such a way that it would trigger hard fork code, which still activates later. Yet others suggest that both the soft fork and the hard fork will be activated at the same time. And some even think the hard fork will come first, followed by SegWit activation later.

While these kinds of details may still need to be worked out, over 50 companies signed the agreement. Combined, they currently represent more than 80 percent of hash power on the network and, according to these companies, $5.1 billion USD in transaction volume as well as 20.5 million Bitcoin wallets.

But there are telling omissions, too. Perhaps most notably, no Bitcoin Core developer is party to the agreement, nor were any of them even present at the meeting. Similarly, none of the entities that fund Bitcoin Core developers — like Chaincode Labs, Blockstream or MIT’s Digital Currency Initiative — signed on. And of course, some 50 companies are only a segment of the Bitcoin industry in the first place; several big players are still missing.

Last but not least, Bitcoin’s broader user base is not involved with the agreement either, nor is the agreement in any way tied to community support.

How the Agreement Compares to Existing Scaling Solutions

Like the DCG agreement, Bitcoin Core’s scaling roadmap includes Segregated Witness as well. It also suggests that a hard fork to further increase the block size limit could be needed in the future, though it does not specify a specific point in time. Most Bitcoin Core developers also believe that a hard fork requires at least a year to prepare, perhaps more. As such, both Bitcoin Core and the DCG agreement share activation of SegWit as a first step in their scaling plans — but not the hard fork part.

However, the SegWit activation mechanism that is part of the DCG agreement slightly differs from the current activation mechanism implemented in Bitcoin Core. Most important, the DCG agreement lowers the required hash power threshold from 95 to 80 percent. And because of how SegWit is designed, activation through the DCG agreement is incompatible with all SegWit-ready Bitcoin nodes on the network.

It may be possible to work around this issue, however. As proposed by Bitmain Warranty engineer James Hilliard, SegWit activation can be made compatible between the DCG agreement and Bitcoin Core, though it’s a bit “hacky.” In short, if miners signal support for SegWit along the DCG agreement with at least 80 percent of hash power, this 80 percent can also start to completely reject any block that does not signal support for SegWit. This activates the current SegWit proposal by Bitcoin Core, as that would reach its 95 percent threshold as well.

Down the road, the DCG agreement’s hard fork is very unlikely to be implemented in Bitcoin Core for a number of reasons, but most importantly because it is contentious.

Other scaling proposals, like Bitcoin Unlimited’s Emergent Consensus or Bcoin’s Extension Blocks, are not necessarily incompatible with the DCG agreement, or at least they don’t need to be.

What the Agreement Requires to Succeed

What the agreement requires to succeed depends on your concept of “success.” But it will be a challenge by any definition.

First off, it should be noted that the proposal — which allows for blocks of up to 8 megabytes — may not be safe. While the full extent of the block size issue is outside the scope of this article, suffice it to say that some think that 8 megabyte blocks are, in fact, a significant risk.

Perhaps even more important, code needs to be written, and it is not yet clear who will actually do this. Moreover, this code should really be reviewed and tested extensively: the plan is to have it carry billions of dollars’ worth of value. This will not be easy to do within six months; impossible, according to some.

Then, this code must be brought into production. For the hard fork in particular, this means that everyone effectively needs to switch to a new protocol. If all signatories of the agreement follow through, it would probably be sufficient to at least keep this protocol running.

It seems obvious that the signatories of the DCG agreement hope that the rest of the Bitcoin ecosystem will also switch to the new protocol once the fork takes place. In that case, the new protocol would (probably) be considered the “new Bitcoin” by everyone.

But given the contention of the proposed hard fork, this currently seems very unlikely.

While it’s impossible to predict the future, it seems almost certain that at least some segment of Bitcoin developers, miners, companies and — most important — users will reject the fork. They will stay put on the existing protocol even if that means it takes much longer for blocks to confirm, or they will roll out a user activated soft fork, or perhaps they will even deploy a counter–hard fork. Under any of these scenarios, the Bitcoin blockchain would “split” into two chains, or more.

The real challenge, therefore, is to get people to use the new chain. And, if that is desired, to get them to consider it the “real” Bitcoin. This will probably be a much harder challenge than forking itself, even for all the companies involved in the DCG agreement.

And most important, for the agreement to succeed in any way at all (perhaps even under a different name than “Bitcoin”), it will require the signatories to follow through. The Bitcoin protocol is difficult to change, and promises or Medium posts alone don’t have any impact on it whatsoever, as several similar commitments have proven in the past.

Using Blockchain Tech to Keep Concert Ticket Prices Honest

BitTicket, the First Digital Events Ticket Platform on the Blockchain

Major events, from sporting to musical, are a significant part of most people's lives, bringing individuals together to enjoy a shared interest. Unfortunately, ticket touts (scalpers) and secondary websites are taking advantage and extorting the event ticketing industry. With big names such as Mumford and Sons, Coldplay, Adele and Ed Sheeran speaking out about this problem, the issue remains. The U.K. government has introduced legislation that aims to prevent the use of bots from purchasing tickets to resell them at inflated prices. Still, more than 21,000 people in the U.K. have reported falling victim to ticket fraud in the last three years with the majority of these reports concerning secondary ticket markets, according to research.  

In order to solve the issues around fraudulent tickets and the high prices associated with them Edinburgh-based Citizen Ticket, the ethical 'David meets Goliath' event ticketing platform backed by blockchain technology, was created by CFO Harry Boisseau and COO Philip Shaw-Stewart. During their time working in the events industry for the past 10 years, the pair has worked on everything from large-scale music events and pop-up food events to underground concerts and charity fundraisers.  

The Problem

In partnership with Get Online Safe and the Society of Ticket Agents and Retailers (STAR), the City of London Police's National Fraud Intelligence Bureau (NFIB) found that over the last three years more than £17 million ($22 million) has been lost to ticket fraudsters.  

In April, the three organizations undertook a series of Facebook flash sales, which saw over 1,500 people attempting to buy music tickets from a fake ticket website called 'Surfed Arts.' Purporting to be a secondary ticket website, the adverts were aimed at certain locations where concerts were taking place over the summer but had sold out. The research found that women over the age of 65 and those who reside in London tried to purchase the most fake tickets; however, men and women aged 35-44 and those living in Birmingham were the least likely to click on the fake advert.

Those who did click on the Surfed Arts website were told they could not buy the sold out tickets before being informed on how they could better protect themselves from becoming a potential victim to ticket fraudsters. According to the NFIB, the idea was to get people to change their online behavior and to consider whether secondary ticket sales are legitimate.

Social media is also becoming another avenue for ticket fraudsters to advertise ticket sales. Data from Action Fraud found that in 2015 there was a 55 percent rise in ticket fraud with major sporting events such as the Rugby World Cup and the Premier League football accounting for a quarter of all incidents of ticket scams. Fraudulent tickets for gigs and festivals represented 15 percent, costing the U.K. public £5.2 million ($6.75 million).

Those who do purchase fake tickets can find that the nature of them can vary. They either don't materialize, never existed or charge hyper-inflated prices through secondary ticket websites than what's listed on a primary ticket website.

A Blockchain Solution

With the help from fellow team member Colin Palmer, CTO, Boisseau and Shaw-Stewart brought to fruition the recent launch of BitTicket, the first digital event tickets on the blockchain for public events, using the cryptocurrency Ethereum Classic. The idea was dreamt up while searching online for Ed Sheeran tickets on a secondary ticket website with high costs.

The team found that not only were there large quantities of tickets being hoarded by secondary ticket websites with increased prices attached to them, but that primary ticket websites were sending them, in bulk, to the secondary ticket websites before they went on sale. However, that wasn't the only problem the team found.

"The event ticketing monopolies own primary ticket websites and secondary ticket trading websites," said Shaw-Stewart, speaking to Bitcoin Magazine. "The secondary ticket website allows the monopolies to collect event tickets from their primary ticket website, then charge highly inflated prices for the tickets on their secondary website under the pretense of being a platform created to allow fans to resell tickets."

As an example, they cited a Robbie Williams concert that was held at the O2 Arena in London. On a primary website, the tickets were being sold for £40 ($52). However, according to Shaw-Stewart, the primary site proceeded to sell 80 percent of their tickets to the umbrella company's secondary sister site. There, the same tickets were being sold for £300 ($390) each.

"There is a problem in the industry we believe to be unethical, the resale of event tickets by secondary ticket websites, often at highly inflated prices."  

With the use of the blockchain, BitTicket is aiming to provide a secure and transparent system which is resistant to fraud and counterfeiting. With every ticket sale publicly verifiable on the blockchain, it locks and guarantees the value of the ticket in a way that is unmatched by private databases and paper systems, says Shaw-Stewart.

bitticket1

It also has inbuilt anti-fraud sales rules to ensure that no secondary ticket website can hoard tickets to control the supply that allows them to charge inflated prices. If the resale rules are broken by secondary ticket websites or ticket touts (scalpers), the fraudulent accounts are frozen and the tickets are made invalid.

Still in the early stages of launching Citizen Ticket, the team is planning on rolling out a large-scale marketing campaign in the coming months to target event organizers and event goers.

The first ever event to use this new blockchain application was the Scottish Street Food Awards in Edinburgh, which took place on May 12. Utilizing the BitTicket platform, the event proved to be a success for the Citizen Ticket team, who said that the platform had performed exactly as they had expected.

"From a customer's point of view very little changed; they purchased and presented their ticket like any other digital ticket," said Shaw-Stewart. "They were asked for ID at the door to confirm ownership of their ticket and that's it, they were in."  

In keeping with the company’s commitment to ethical practices, Citizen Ticket also works with two charitable partners: the Movember Foundation and SkatePal. Through ticket sales made on the platform, donations are made to these two charities.

With an array of events already listed on the platform, as well as its fundraising initiatives, the team is hoping to level the playing field for the industry with BitTickets.

"We hope that the launch of BitTicket will usher in a new era of ethical event tickets where both fan and artist are protected from the unethical practices of ticket touts and secondary ticket websites," concluded Shaw-Stewart.

These Two UASFs Could Activate SegWit

BIP 148 and BIP 149: the Two UASFs to Activate SegWit

Segregated Witness (SegWit), the Bitcoin protocol upgrade proposed by the Bitcoin Core development team, was originally designed to activate via the Bitcoin Improvement Protocol 9 (BIP 9) standard, a hash-power signalling mechanism. This would allow the Bitcoin ecosystem to coordinate the upgrade relatively safely through miner readiness.

But with the SegWit proposal in particular, BIP 9 no longer serves just to signal readiness. Miners as well as users increasingly see BIP 9 as a sort of miner vote on the desirability of the protocol upgrade. And some miners even seem to utilize it as a negotiation chip for protocol development.

The pseudonymous developer who goes by the name “Shaolinfry” considers this an abuse of the coordination mechanism. He therefore recently proposed an alternative activation scheme: a user-activated soft fork, better known as a “UASF.”

Shaolinfry also drafted two specific UASF proposals: BIP 148 and BIP 149. Both of these are currently “in the running” for user adoption. And speaking with Bitcoin Magazine, Shaolinfry, at least, seems sure that one of them will be accepted by the network.

“There is no universe in which SegWit will not get activated.”

SegWit and the UASF

A soft fork is a change to the Bitcoin protocol that introduces new rules or tightens existing ones. This makes soft forks backward compatible: nodes that did not upgrade should remain part of the same Bitcoin network.

Segregated Witness is a soft fork that would increase Bitcoin’s block size limit and solve some longstanding protocol issues. While it’s always hard to say with conclusive certainty, the proposal seems to have broad support within the Bitcoin ecosystem. Many wallets, exchanges and other companies in the space have indicated they are ready for it, while an overwhelming share of reachable nodes on the network have implemented the solution, too.

As per BIP 9, the current implementation of SegWit activates if about 95 percent of hash power signals support within a two-week difficulty period before November. However, hash power support has so far stagnated at around 30 percent.

This apparent mismatch between the ecosystem and hash power support is why some — like BIP 9 co-author Rusty Russell — are increasingly thinking the activation method was a mistake.

And Shaolinfry does, too.

“The main issue with BIP 9 is that it has a veto of only about 5 percent of hash power,” Shaolinfry explained. “That veto could be intentionally or unintentionally triggered. Intentionally, like how miners are currently blocking SegWit activation. Or unintentionally due to upgrade apathy.

“Miner activation also draws attention to mining pool operators politically. The whole world is paying attention to who is and isn’t signaling. That is undesirable. And what if the soft fork is for something that could make governments angry? We know this is the case in China for anonymity features, and increasingly in the United States as well.”

As such, Shaolinfry proposed activating SegWit through a UASF.

The idea behind any UASF, in short, is that users simply activate the soft fork at an agreed-upon point in time. If these users represent a majority of the Bitcoin economy — exchanges, merchants, users — miners are financially incentivized to follow the new soft fork rules. If they don’t, they could mine invalid blocks (according to the majority of the Bitcoin economy), and the “bitcoins” they earn would be worth less — or worth nothing at all.

Once a majority of hash power does follow these financial incentives and enforces the new rules, the rest of the Bitcoin ecosystem should automatically follow, just like with any other soft fork.

BIP 148

The first UASF proposal drafted by Shaolinfry is BIP 148.

BIP 148 is an interesting take on a UASF because it is actually designed to trigger the existing BIP 9 SegWit-activation threshold.

“If you want to redeploy SegWit, you must wait for the current deployment to expire by November of this year because many Bitcoin nodes won’t accept it otherwise,” Shaolinfry explained. “BIP 148 is a way to make the current BIP 141 deployment activate before November. That’s faster, and has the advantage that more than 70 percent of nodes has already upgraded.”

Specifically, starting on August 1, BIP 148 nodes will reject any Bitcoin blocks that do not signal support for Segregated Witness via BIP 9. So, if the majority of the Bitcoin economy enforces BIP 148, miners will have to signal support for SegWit in order not to have their blocks rejected.

Once these miners do signal support for SegWit, this signaling would also trigger all the “normal” SegWit nodes on the network. All these nodes would then enforce SegWit, even if they didn’t participate in the BIP 148 activation themselves.

And, from a game theory perspective, it may even be viable for a relatively small minority of the Bitcoin economy to get BIP 148 activated. Miners should have little to lose by signaling support for SegWit, but something to lose from not signaling: a smaller total number of users to sell their bitcoins to. As such, even a modest but committed BIP 148 user base could potentially be enough.

Finally, echoing his Medium post on Litecoin’s SegWit activation, Shaolinfry noted that even the possibility of such a UASF could be enough to make miners signal support — without even needing nodes to actually enforce it.

BIP 148: Risks and Incentives

There are, however, some risks. These are why some prominent Bitcoin Core developers — like Blockstream CTO Gregory Maxwell and Chaincode Labs Co-Founder Suhas Daftuar — consider BIP 148 too disruptive.

Per BIP 148, otherwise valid blocks would be rejected merely because they don’t include a signal. The rejection of these blocks would waste miners’ resources and detrimentally affect Bitcoin’s security.

Moreover, if only a minority of hash power enforces the new rules — either because they ignore financial incentives or because only a small minority of the economy enforces the new rules in the first place — the Bitcoin blockchain could split in two. There would be a “SegWit chain” and a “non-SegWit chain.” That would open up a new can of worms, where the risks for users on both ends of the chain are not the same.

“The incentives are clearly there for miners to follow the economy,” said Shaolinfry in response to this criticism. “But indeed, there is a chain split risk if less than 51 percent [of] miners comply and run BIP 148. However, even in this circumstance, the non-BIP 148 chain is asymmetrically disadvantaged, and will almost certainly be completely wiped out. The SegWit chain will always be more valuable, and once a majority of miners switches to that chain, the non-SegWit chain will disappear altogether.”

Furthermore, from a certain threshold on, the risk of a chain split become smaller as it gathers more support. This is why another prominent Bitcoin Core developer, Luke Dashjr, is throwing his weight behind the proposal.

And to avoid these kinds of risks, there could be another twist to BIP 148 as well, Shaolinfry pointed out:

“The interesting thing about BIP 148 is that any majority of miners can trigger it — it doesn’t have to be 95 percent. If 75 or even just 51 percent of hash power starts rejecting non-signaling blocks per August 1, they will always claim the longest chain. So really, all miners will from then on have to signal support and activate SegWit — or have all their blocks orphaned by the network.”

Finally, Shaolinfry may also release code — “Segsignal” — to allow miners to signal whether they will deploy BIP 148 and under what condition. Using this, miners could, for example, agree to activate SegWit through BIP 148 if, and only if, 51 percent indicates that they are willing to.

“This should remove any risk of a chain-split, even a short-lived one,” Shaolinfry said.

BIP 149 (and BIP 8)

Shaolinfry’s alternative UASF proposal is BIP 149.

BIP 149 utilizes an entirely new soft fork activation mechanism: BIP 8. BIP 8 resembles BIP 9 in that it initially allows miners to activate the soft fork through hash power. However, as opposed to BIP 9, the soft fork proposal doesn’t just time out by the end of the activation period. Instead, it sets an activation deadline. If that deadline is reached, nodes activate the soft fork regardless of hash power support.

There is a particular technical advantage of BIP 149 over BIP 148: it is less intrusive for miners. While BIP 148 effectively forces miners to signal, with BIP 149 miners don’t actually have to do all that much. They can support SegWit if they want to. If not, they may want to run a so-called “border node” to filter invalid transactions and blocks post-activation, but that’s about it.

Shaolinfry plans to implement BIP 149 in dedicated Bitcoin software if BIP 148 doesn’t succeed, and when the current BIP 9 SegWit proposal has expired by mid-November. The activation deadline for BIP 149 is then scheduled for early July 2018.  

Some developers, like Maxwell, are in no rush to activate SegWit and consider BIP 149 preferable. But others, like Dashjr, believe it will take too long.

Shaolinfry himself noted:

“BIP 149 is not too slow from a technical point of view. But, I do think the longer SegWit isn’t activated, the more gremlins and obstacles are going to besiege Bitcoin. So if the ecosystem rallies around BIP 148, that would bring this nightmare to a close.”

Bitcoin & Ether Price Analysis: Bitcoin Still Going Strong While Ether Wearies

BTC ETH Price Analysis

Bitcoin and Ethereum continue to push all-time highs (ATHs) by most available metrics: price, market capitalization, daily traded volume, hash rate, transactions per day, etc.

mrkt cap.png

There appears to be a multifactorial convergence of fundamentals and technicals allowing for this surge to happen:

1. On-ramps

Specifically Coinbase for U.S. citizens, which now allows new users to purchase bitcoin (BTC), ether (ETH) or litecoin. Leading up to and even during the 2013 bubble, purchasing cryptocurrency was difficult for the average user. Know-Your-Customer (KYC) and Anti-Money Laundering (AML) checks cause a slight lag in on-ramping by limiting the total coins a new user can purchase. I expect the fuel for this rally to continue for at least another week.

2. Visibility in mainstream and popular media

At this point, you cannot use any social media or news source without hearing about Bitcoin. Everyone I’ve spoken with outside of the Bitcoinosphere is aware of its existence. Although purely anecdotal, this trend suggests Bitcoin is gaining visibility.  

3. ICOmania

Initial coin offerings (ICOs), similar to IPOs, allow for a company or brand to tokenize its assets through crowdfunding, most of which are done on the Ethereum blockchain. The quantity and rate of new ICOs remind many traders of the dot-com bubble due to large influxes of cash for almost every project.   

4. An agreement on the block size debate

The ongoing block size and scalability debate was stifling innovation surrounding Bitcoin. On Monday, it was announced that Barry Silbert and Bitcoin Unlimited proponents reached an agreement to activate SegWit now and hard fork in four months. Members of the Bitcoin Core community were not involved in the discussion. Shaolinfry, the user-activated soft fork (UASF) dev, had this to say regarding the agreement. UASF nodes continue to increase, despite the agreement.

To be clear, the proposal, as far as I can see, does not activate BIP 141, but is a completely new deployment that would be incompatible with the BIP 141 deployment. I’m not sure how that can be considered “immediate” activation. - Shaolinfry

uasf_nodes_all.png

5. Prices were already pushing ATHs  

Trend since 2015 has been bullish with several periods of extended consolidation. Price continues to break ATHs in large part due to further bullish technicals and market structure with every pullback/correction. Whether or not current price represents a bubble or euphoria is a bit irrelevant. What is more important is to look for signs of exhaustion. One such sign of exhaustion would be a toppy chart pattern such as an M double top or growing bearish divergence on a weekly chart.

Bitcoin

weekly.png

A bear div would consist of a higher high in price and a lower high on RSI, a measure of momentum. This would suggest lack of strength holding up price. In the case of BTC, however, there has been a steady increase in volume since the beginning of the year.

vol.png

As price continues to break ATHs almost daily, we can expect a large increase in volatility and range expansion, especially because there is no previous market structure at these levels. However, there are indicators that help determine support and resistance levels above ATH levels, the most common being Fibonacci extensions. Drawn from previous ATH to low, this would yield a target of ~$2,400.

daily.png

On a low timeframe, you can see yesterday’s $200+ volatility, which quickly rallied 50 percent of the drop.

15min.png

The current immediate target is the local top of $2,248.

Ethereum

Ethereum, on the other hand, is beginning to show signs of exhaustion. The weekly chart is showing a decline in volume since March, with ETH/USD pushing the top limit of RSI, and the ETH/BTC pair showing bear div.

ethusd.png

ethbtc.png

Structure currently has all the makings of an M double top. I would expect another retest of the previous consolidation level before moving higher. if Bitcoin makes a push past $2,400, however, it may drag up Ethereum with it as well.

ethusd 1h.png

The upside target should be between $198 and $217 according to Fibonacci extensions.

upside eth.png

Summary

  1. Bitcoin and Ethereum continue to push the envelope for almost every available metric and show little signs of slowing.

  2. Reliable on-ramping coupled with awareness and popularity continue to fuel demand.

  3. Despite several weeks of large gains, the possibility of continuing to further ATHs for Bitcoin remains high.

  4. With declining volume and a growing bear div on high timeframes, Ethereum is beginning to show signs of slowing.

Bitcoin Trading Bots
