Bitcoin Price Analysis: Potential Bearish Continuation Sets Up Lower Lows

Bitcoin Price Analysis

Shortly after a sharp drop from the mid $14,000 to the lower $9,000s, bitcoin saw a strong bounce to the upper $11,000s. At the time of this article, bitcoin appears to be consolidating and is ready to make its next move:

fig1

Figure 1: BTC-USD, 1 Day Candles, Macro View

In the previous BTC market analysis, we discussed the distribution trading range the market fell out of as it reached for lower support boundaries. Ultimately, it found support on the macro 50% retracement values near $10,000. Once it broke south of the trading range, the price fell sharply and with high volume:
fig2

Figure 2: BTC-USD, 15 Minute Candles, Current Support and Resistance Levels

After bouncing off the macro 50% values, the market rallied and ultimately tested the linear trendline shown in Figure 1. Now, after several failed attempts to break the linear trendline’s resistance, the market finds itself in a consolidation pattern where it decides where it will move next.

fig3

Figure 3: BTC-USD, 60 Minute Candles, Potential Bear Flag

One possibility to keep a close eye on is this potential, strong bear flag. After finding support on the macro 50%, the subsequent rally saw decreasing volume throughout the length of the movement. This sort of price action could potentially lead to a bearish continuation with a measure move between $4000 and $5000 — a price target of approximately $6,000 – $7,000. If a drop of this magnitude continues the downtrend, we can expect to find support on the 61% macro Fibonacci retracement values shown in Figure 1.

It’s important to note that bitcoin has a penchant for breaking upwards when all signs say “down,” so tread lightly and wait for confirmation of the move. Confirmation of the bear flag breakout would show a pretty obvious outlier in volume, combined with wide price spread.

Summary:

  1. Bitcoin recently saw a steep drop in price where it ultimately found a local bottom in the low $9,000s.
  2. Since it bottomed out, it has seen a rally on decreasing volume which leaves the door open for a bearish continuation.
  3. If the bearish continuation continues, expect support on the 61% macro retracement values.

Two New Services Could Help Investors Rate Cryptocurrencies

Cryptocurrency Rating Services Launched

Increasing interest in cryptocurrencies has led to an influx of new investors. Unlike traditional markets, there are few tools that can help people make informed decisions, a situation that has already begun to claim victims in a particularly volatile environment.

In separate announcements, Weiss Ratings and Intercontinental Exchange (NYSE: ICE) have announced the introduction of new financial tools to help investors navigate the cryptocurrency market and make smarter investments.

Weiss Ratings, an established independent rating agency of financial institutions, says they will begin issuing ratings for cryptocurrencies on January 24, 2018, to help investors make informed decisions.

ICE, an operator of a network of global futures, equity and equity options exchanges, is partnering with blockchain technology provider Blockstream to launch the Cryptocurrency Data Feed (CDF).

Weiss Ratings Takes On Cryptocurrencies

Founded in 1971, Weiss is an independent rating agency of financial institutions. They will begin issuing letter grades for cryptocurrencies including Bitcoin, Ethereum, Ripple, Bitcoin Cash, Cardano, NEM, Litecoin, Stellar, EOS, IOTA, Dash, NEO, TRON, Monero, Bitcoin Gold and many others.

According to Weiss Ratings founder Martin Weiss, the data they are using is a combination of purchased data and data collected through other sources. It is updated on a daily basis, covering a sliding 12-month window.

Regressive testing to verify past data that the company uses to confirm predictions is still ongoing, but results have been accurate thus far, Weiss told Bitcoin Magazine.

“We have built an analytical technology over the years using intelligent models to replicate the real world and we are applying [these] to cryptocurrenc[ies]. These have been very accurate for many years.”

Ratings are built up across multiple indexes. The company built new models to reflect cryptocurrency data and developed an overall grading system that is broken down into four separate sub-models:

  1. Risk Index — The level of risk involved in the investment, based on factors like price activity and volatility.
  2. Reward Index — The potential reward outcome, based on historical patterns of buying and selling.
  3. Technology Index — A primarily manual process, where company analysts review the source code and white papers, analyze price movement and make ratings in a Query Tree (their internal software) to generate a quantitative result.
  4. Adoption Index — A measurement of adoption along two dimensions: how broadly it is adopted, transaction speed, settlement times, etc.

“A weighted average of those 4 indices is used to get the final grade,” said Weiss. “The goal at Weiss is to empower the investor to make prudent decisions.”

ICE Data Services: Real-Time Trading Data

The Cryptocurrency Data Feed (CDF) is a multi-asset and multi-venue data feed, capturing nearly 80 percent of cryptocurrency exchange trading volume over more than 15 exchanges around the world. It measures leading cryptocurrencies against the U.S. dollar and other major currency pairs.

The captured data is normalized to create a unique number sequence to identify the transaction, details of where the trade took place, quantity, price, currency, timestamp and other relevant order book data. This is designed to enable ICE Data Services’ customers to receive global market–representative trading data in a real-time feed with high-quality information.

“With the broad array of cryptocurrencies and exchanges, and given the price variances between exchanges, it’s critical that investors have a comprehensive source of pricing information,” said ICE Data Services President and COO Lynn Martin in a statement.

According to Blockstream SVP of Business Affairs Alex Fowler, the initial exchange partners set up through cooperative agreements include Bitbank, Bitfinex, BitMEX, Bitso, Bitstamp, BtcBox, BTCC, CEX, Coinfloor, Coincheck, itBit, GOPAX, OKEx, SurBTC, The Rock Trading, Unocoin, Vaultoro and Zaif, with more coming soon.

The data is collected using the exchanges’ APIs and, in some cases, by setting up dedicated connections with them. The current feeds lack standardized formatting and information: part of what ICE is providing is a single source that consolidates and standardizes the data, which will average out the information from the multiple sources into a more accurate overall view.

Historically, the data currently only goes back to the initial integration; however, Blockstream is working with the exchanges to try and incorporate older data as well.

Fowler told Bitcoin Magazine, “We believe that a consolidated data source, resulting from the combined participation of a strong and growing list of exchange partners globally, will enable us to address these gaps and thereby promote better liquidity, price stability, and public confidence in cryptocurrency as asset class.”

CDF will include bitcoin and a wide range of cryptocurrencies and currency pairings on launch; the final list will be on their website. ICE will develop and publish a selection of criteria for decisions on the addition and/or removal of assets in the feed. This will be an ongoing process as the market evolves. Access to the real-time CDF will be available to subscribers of ICE Data Services’ Consolidated Feed in March 2018.

What is Ripple?

ripple101.jpg

By Shawn Gordon

What is Ripple? Technically speaking, is Ripple a cryptocurrency in the mold of Bitcoin? The short answer is probably “no,” but that doesn’t stop it from often being lumped into that same category.

What is Ripple?

Originally released in 2012 as a subsequent iteration of Ripplepay, Ripple is a real-time gross settlement system (RTGS), currency exchange and remittance network. Using a common ledger that is managed by a network of independently validating servers that constantly compare transaction records, Ripple doesn't rely on the energy and computing intensive proof-of-work used by Bitcoin. Ripple is based on a shared public database that makes use of a consensus process between those validating servers to ensure integrity. Those validating servers can belong to anyone, from individuals to banks.

The Ripple protocol (token represented as XRP) is meant to enable the near instant and direct transfer of money between two parties. Any type of currency can be exchanged, from fiat currency to gold to even airline miles. They claim to avoid the fees and wait times of traditional banking and even cryptocurrency transactions through exchanges.

How Is It Fundamentally Different From Bitcoin?

It is the validating servers and consensus mechanism that tends to lead people to just assume that Ripple is a blockchain-based technology. While it is consensus oriented, Ripple is not a blockchain. Ripple uses a HashTree to summarize the data into a single value that is compared across its validating servers to provide consensus.

Banks seem to like Ripple, and payment providers are coming on board more and more. It is built for enterprise and, while it can be used person to person, that really isn't its primary focus. The main purpose of the Ripple platform is to move lots of money around the world as rapidly as possible.

Thus far, Ripple has been stable since its release with over 35 million transactions processed without issue. It is able to handle 1,500 transactions per second (tps) and has been updated to be able to scale to Visa levels of 50,000 transactions per second. By comparison, Bitcoin can handle 3-6 tps (not including scaling layers) and Ethereum 15 tps.

Ripple’s token, XRP, isn't mined like Bitcoin, Ethereum, Litecoin and many other cryptocurrencies. Instead, it was issued at its inception, similar in fashion to the way a company issues stocks when it incorporates: It essentially just picked a number (100 billion) and issued that many XRP coins.

What is XRP and What’s It Used For?

As a technology, the Ripple platform may have real value and real history that validate the claims they make for its efficacy. The XRP token itself, however, seems to have negligible use cases. In fact, Ripple had planned to phase it out — at least, until fevered interest in cryptocurrencies began to take off in 2016. Nevertheless, as CNBC noted today, if Ripple hits $6.57, its market capitalization will be bigger than Bitcoin’s.

There are 100 billion XRP tokens that were issued by the Ripple company. At the moment, the company promises that this is the total number of XRP that there will ever be (though, technically, there is nothing to stop them from issuing more tokens in the future). Ripple’s hub-and-spoke design positions XRP in the middle as a tool that is fungible with any currency or digital asset, such as frequent flyer miles. Ripple can settle a payment in 3.5 seconds through XRP and have it available and spendable. The use of XRP is totally independent of the Ripple network in general; that is, banks don't actually need XRP to transfer dollars, euros, etcetera which is what many small investors might be missing when they are buying the token.

What Is Ripple’s Value Proposition?

The value here is the Ripple network itself and its ability to move assets around the world quickly, rather than in the XRP token.

Banks are able to use the Ripple software to shift money between different foreign currencies. Currently, this is typically accomplished using SWIFT, a system that is cumbersome and relies on the banks having separate accounts in every country they work in. Ripple says it has signed up more than 100 banks (compared to SWIFTs 11,000 financial institutions) including American Express.

So Why All the Hype?

While Bitcoin has seen a dramatic rise in price over the course of 2017, the end of the year saw the cryptocurrency almost breaking $20,000. As the price drove higher, we saw a massive increase in price for a large number of altcoins, with Litecoin jumping from $50 to nearly $400, Ethereum doubling, NEM and EOS going up by a factor of five, and the list goes on and on. The fear of missing out has driven many investors wild and “lower-priced” currencies are attractive to new investors who mistakenly think that the high price of an entire BTC puts the currency out of their reach.

Add to all the hype the rumors that had been swirling on social media through December 2017, that Coinbase was going to list Ripple, which caused the price to surge, which in turn prompted Coinbase to address the rumors in a more generic fashion in this blog post on January 4, 2018:

“As of the date of this statement, we have made no decision to add additional assets to either GDAX or Coinbase. Any statement to the contrary is untrue and not authorized by the company.”

ripple chart jan19

The Coinbase announcement caused a big drop in Ripple, back to around the same levels as before the rumors began. SInce then, Ripple has both dipped dramatically and recovered, as have many other volatile cryptocurrencies. While Coinbase doesn’t support Ripple, there are a number of ways for people to acquire Ripple, should they still want to.

Words of Caution

There has been a lot of ink used on criticizing Ripple as well. The complaint from Bitcoin and other blockchain enthusiasts is that Ripple’s centralized control is in direct contrast to the ideals and advantages of decentralized blockchains like Bitcoin.

Ripple also maintains a trusted Unique Node List (UNL) that is meant to protect against potentially malicious or insecure validating servers. It is the UNL that controls the network rules, presenting a conundrum: On the one hand, it protects against problematic validators, but, in theory, a regulating body or government could come in and force a change that isn't necessarily desirable or is downright invasive. Furthermore, because of a FinCEN violation and fine in 2013, Ripple has updated its policies and will only recognize and recommend gateways that are in compliance with financial regulations.

New York Times reporter Nathaniel Popper commented on Twitter that he has yet to find a bank that anticipates using the XRP token in any meaningful way. Ripple’s CEO, Brad Garlinghouse, has denied Popper’s claims stating, “Over the last few months I’ve spoken with ACTUAL banks and payment providers. They are indeed planning to use xRapid (our XRP liquidity product) in a serious way.” However, as Popper points out, even the banks that he contacted at Ripple’s suggestion were non-committal in their plans to implement Ripple anytime soon.

According to the Financial Times, of the 18 banks and financial services companies publicly linked to Ripple, most of them stated that they “had not yet gone beyond testing” while a few had moved on to using Ripple’s systems “for moving real money.” However,  not one of the 16 companies that responded had used the XRP token.

Cornell IC3 Researchers Propose Solution to Bitcoin’s Multisig “Paralysis” Problem

Cornell IC3 Researchers Propose Solution to Bitcoin’s Multisig “Paralysis” Problem

Owning cryptocurrency comes with its own set of challenges. One of the biggest of those challenges is managing the private keys that enable you to spend funds. Lose your private keys, and your money is gone.

In a business environment, a common way to manage funds owned by multiple people is via what’s called a multisignature (multisig) address, a type of smart contract requiring two or more parties to sign off on a transaction to move the funds. 

This can be problematic, however. Let’s say you have a three-of-three multisig that requires you and two business partners to sign off on a transaction. If one person dies, disappears or becomes incapacitated, those assets become frozen — a risk some might feel uncomfortable with when dealing with tens of thousands of dollars or more.   

One way to ameliorate that risk might be to opt for a two-of-three multisig, where only two instead of all three individuals need to sign off on a transaction. But that’s not a complete solution either. Two players could conspire against the other one and run off with the money.

What now? If your funds are on the Ethereum blockchain, you could write a smart contract that would allow you to free the funds if one person in your trio disappeared.

However, Bitcoin with its limited scripting language makes things more difficult. “This seems like an unsolvable problem if you think about the traditional tools,” said Ari Juels, a professor at Cornell Tech and co-director of the Cornell Initiative for Cryptocurrencies and Contracts (IC3).

Paralysis Proofs

In a paper titled “Paralysis Proofs: How to Prevent Your Bitcoin from Vanishing,” researchers Fan Zhang, Phil Daian, Iddo Bentov and Ari Juels from the IC3 outline how to deal with what happens when a party is unable, or unwilling, to sign off on a multisig transaction in Bitcoin. The solution involves a combination of blockchain technology and trusted hardware — Intel SGX, in this case.   

Trusted hardware allows you to run code inside a protected enclave. Even a computer’s own operating system is unable to access data inside an enclave, so if your computer were to be hacked, the code in the enclave would remain secure.

IC3’s solution proposes replacing a trusted third party, such as a lawyer or a bank, who would put money in an escrow, with a trusted hardware solution that retains control of a master key to the funds.  

If one of the three people in the contract dies, the other two initiate a “paralysis proof.” That proof is based on a challenge sent to the missing third person. If the missing person responds to the challenge, the money stays put. If the missing person does not respond, the trusted hardware releases the funds to the remaining two players.  

Trusted hardware is only part of the solution, however. If the third person were to try and respond to the challenge request with an indication she is still alive, conceivably, the other players could intercept that message. To ensure that does not happen, the second half of IC3’s solution involves sending the message via the blockchain, which provides a tamper-proof and censorship-resistant medium.    

“By combining these two [methods], we can achieve the exact properties we’re after,” Juels explained to Bitcoin Magazine. “We can enable trusted hardware to determine whether or not somebody is alive, and there is no way to prevent a relevant message from getting transmitted if it is coming through the blockchain.”   

How It Works

Put simply, this is how to achieve a paralysis proof as outlined by the IC3 researchers:

  • Two players suspect a third is dead, so they post a challenge on the blockchain. The challenge consists of a tiny “dust” UTXO that the third person must spend within a certain period of time, say 24 hours, to prove she is alive.
  • The two players also get a “seize” transaction they may post to the blockchain later to collect the funds, if the third person does not respond to the challenge.
  • If the third person sends back a response by spending the UTXO, the game is over; the two others are not able to take control of the funds.  
  • Alternatively, if the third person does not return an “alive” signal by spending the UTXO before the time-out, then the two others can use the “seize” transaction to take control of the funds.  

This not the only use case for a paralysis-proof system. Juels thinks the solution would work well in any situation that called for a controlled access to private keys that could not otherwise be maintained on a blockchain. “It is actually a very general scheme you could use for lots of other purposes,” he said.   

For instance, a paralysis-proof system could be used as a dead man’s switch for control over the release (or decryption) of leaked information or a journalist’s raw materials. It could also be used in numerous ways to control daily spending limits from a common pool of money or as a conditioned expenditure based on an outside event (as reported by an oracle), like a student getting good grades or a salesperson meeting a sales quota.   

“Basically, you can a rich set of conditions around the expenditure of money using the fact that a trusted hardware kind of acts like a trusted third party,” said Juels.

The Origin Protocol is a set of open-source blockchain protocols for buyers and sellers of services like car-sharing or home-sharing to transact on a decentralized, open web platform.

The protocol’s applications will store transactional data such as pricing and availability directly on the blockchain.

Leveraging the Ethereum blockchain and the Interplanetary File System (IPFS), the Origin platform will create and book services and goods in a decentralized way, without traditional intermediaries.

Recently, Origin launched its functional, completely decentralized prototype Origin Protocol Demo DApp, live on the Ethereum test network. It also announced that several companies have committed to developing further applications on the Origin platform.

“Our vision for Origin is to create protocols that allow marketplaces to be governed by a set of rules instead of corporate rulers. We want to eliminate the rent-seeking middlemen, maximize personal liberty, reduce censorship and redistribute value to the early participants in the network,” Origin co-founder Josh Fraser said in conversation with Bitcoin Magazine. “Partners are building on Origin because they realize they can get to market sooner and we can share network effects by working together.”

Tackling the Problems of the Centralized Marketplace

Uber and Airbnb, the hugely popular marketplaces for ride-sharing and home-sharing, are usually considered the leading players in the emerging “sharing economy.” Another buzz phrase, “people as a service,” describes the business models of these two companies, both of which attracted funding that values them in the tens of billions of dollars.

Consumers perceive that Uber and Airbnb are faster, cheaper and better alternatives to traditional services like taxis and hotels, delivered via sophisticated yet easy to use apps. But, while the consumer has the impression that they are buying services directly from individual providers in decentralized, P2P networks, Uber and Airbnb are centralized systems where transactions between individual consumers and providers are routed through infrastructure, hubs and software that belong to the companies that own the platform.

Centralization makes Uber and Airbnb vulnerable to regulatory actions, and there is the possibility that both services could be shut down by the government at any time. In the meantime, besides taking a fee, the platform owners are in complete control of the networks and the individual providers and are often accused of predatory behavior.

“Look at Uber and Airbnb as examples,” said Fraser. “Both companies have been banned or heavily regulated in cities all around the world. Likewise, those companies have a history of banning certain individuals for life from ever using their marketplaces.”

Uber and Airbnb (the Services) without Uber and Airbnb (the Companies)

According to data provided by Origin, Uber, Airbnb and other centralized sharing marketplaces are expected to earn $40 billion in platform fees annually by 2022, and the sharing economy as a whole is expected to top $335 billion by 2025. Some centralized sharing services charge upwards of 30 percent fees for hosting transactions.

Origin wants to cut out these middlemen with new standards based on blockchain technology.

The Origin platform “enables people to freely transact on the blockchain in decentralized marketplaces without rent-seeking middlemen,” says Coleman Maher. who recently joined Origin as its first business development hire. “We aim to eliminate excessive transaction fees, reduce censorship and redistribute value back to the community.”

“We imagine a broad collection of vertical use cases (e.g short-term vacation rentals, freelance software engineering, tutoring for hire) that are built on top of Origin standards and shared data,” reads the Origin product brief. Origin applications will be able to share users, creating a “shared network effect” that could benefit all application providers, as well as the consumers.

Bee Token, SnagRide, JOLYY, Acquaint, Aworker, BlockFood, Edgecoin and ODEM have committed to building on the Origin platform. More partners will be announced in the coming months.

The first two projects are in Airbnb and Uber territory. The Bee Token team, a group of former employees from Google, Facebook, Uber and Civic, is building a middleman-free, peer-to-peer network of hosts and guests on the decentralized web, with the stated goal of “reinventing the home sharing economy.” SnagRide is a ride-sharing application for mid– to long-distance rides, which leverages artificial intelligence and blockchain-powered smart contract technologies to smartly manage drivers and passengers willing to travel together between cities and share the cost of the trip.

The Origin ecosystem will offer incentives based on the Origin token, an ERC20 utility token on the Ethereum blockchain, described in the Origin white paper. The Origin token, to be distributed later in 2018, is the currency used for transactions on the Origin platform. However, the Origin team plans to implement on-the-fly conversions of fiat currencies and Ethereum to the Origin token in future releases.

Blockstream Releases Lightning Charge, Launches Test E-Commerce Store

Blockstream Releases Lightning Charge, Launches Test E-Commerce Store

Following the release of the first Bitcoin Lightning Network white paper, published in February 2015, developers have been working on Lightning Network implementations to enhance the throughput and usability of the Bitcoin network. For an overview, see this three-part series on “Understanding the Lightning Network.”

In December 2017, lightning developers ACINQ, Blockstream and Lightning Labs, announced the 1.0 release of the Lightning protocol and the world’s first Lightning test payments on the Bitcoin mainnet across all three implementations. The standardization and deployment of the Lightning Network’s second-level, off-chain payment layer is expected to result in instant bitcoin transactions, improved scalability and lower fees, enabling fast and cheap micropayments.

Blockstream’s implementation of the Lightning spec, c-lightning, is a low-level technology designed to implement the Lightning spec without added complexity. At the same time, Blockstream realizes that developer tools are needed to unlock the power of Lightning for advanced applications, such as those that integrate with credit card companies and with existing online payment systems.

Blockstream is releasing the Lightning Charge complementary package for c-lightning to make it simpler to build sophisticated applications on top of c-lightning.

“Web developers will be able to work with c-lightning through their normal programming techniques, and they’ll also get expanded functionality such as currency conversion, invoice metadata, streaming payment updates and webhooks,” reads the Blockstream announcement. “Together, these additions make it easy for developers to use c-lightning to create their own, independent web-payment infrastructures.”

Lightning Charge is a micropayment processing system written in node.js. It exposes the functionality of c-lightning through its REST API, which can be accessed through JavaScript and PHP libraries, both of which have also been released through the Elements Project.

"Lightning Charge makes integration with the Lightning Network much simpler, since it bridges the needs of application developers and the underlying infrastructure, to provide a simple and extensible way to accept Lightning payments," Blockstream developer Christian Decker said in conversation with Bitcoin Magazine.

“Since the introduction of Lightning Charge, less than 48 hours ago, we have seen a dramatic interest in the Lightning Network, both on the user as well as the developer side,” Decker added. “We have gotten a lot of feedback, and the mainnet network has doubled in the number of participants."

The desired effect of the Lightning Charge launch was to reach a wider audience, get early feedback from future users and to showcase what will be possible in a not-so-distant future, and I think we have achieved that goal.

Israeli entrepreneur Nadav Ivgi, founder of Bitrated, worked with Blockstream developers to create Lightning Charge. “Together with him we built this new code, or this immediate piece of software that provides this nicer to use interface,” said Decker.

“So far the development for Lightning has been mostly on the network side of things. It’s been very much this close-knit group of people that are building it and are trying to build the infrastructure. Infrastructure is nice to have. But if nobody can actually use it then it’s not worth much, right?”

To test Lightning Charge, Blockstream is launching the Blockstream Store, a working e-commerce site that allows users to make small purchases of stickers and t-shirts. “By offering an early demonstration of this cutting-edge technology, we hope to bring Lightning to life with real-world functionality, providing a way for you to test Lightning and become a part of the micropayment revolution,” states the Blockstream announcement.

The Blockstream Store, built on WordPress and WooCommerce, connects with Lightning Charge and c-lightning through a WooCommerce Lightning Gateway, which Blockstream also released as part of the Elements Project.

The only way to purchase the items in the Blockstream store is with a Lightning payment. A disclaimer warns that, although the products sold in the store are real, this store is for testing and demonstration purposes only.

“Lightning is still very new and contains known and unknown bugs,” reads the disclaimer, adding that users may lose funds.

"We believe this is an important step towards a full rollout of the network as a whole, however we’d like to remind users that the Lightning Network is still experimental and that testnet is to be preferred for testing before making the jump to mainnet," Decker told Bitcoin Magazine.

Hyperledger’s Behlendorf: 2018 Will Bring Breakthrough Blockchain Developments

hyperledger_behlendorf.png

Brian Behlendorf is confident that 2018 will be a peak year, not only for Hyperledger — the international consortium of companies and organizations developing open source, permissioned blockchain technology — but also for blockchain technology in general as businesses and governments recognize the potential power of distributed ledgers and smart contracts.

“2018 will be the year that Hyperledger and blockchain come into their own. Projects demonstrating real world solutions, like Change Healthcare, that will enable healthcare systems to better and more efficiently process claims and payments, will launch this year.”

Hyperledger, founded in 2015, incubates and promotes blockchain technologies for business, including distributed ledgers, client libraries, graphical interfaces and smart contract engines.

Their 200 members include leading companies in finance, banking, Internet of Things, supply chains, manufacturing and technology development.  

“2017 was a milestone year for Hyperledger both for new members and for new technical breakthroughs. In 2017 we doubled our membership, gaining companies like American Express, Cisco, Daimler and Baidu, and we’re expecting more companies and organizations to join in 2018,” said Behlendorf.

“On the technical side, 30 companies and more than 100 developers contributed to the launch of the first production ready Hyperledger blockchain framework called Hyperledger Fabric,” he added.

According to Behlendorf, an important part of Hyperledger’s mandate is to also help educate and train the workforce for the many new blockchain opportunities coming in 2018.

“We’re happy to have launched our new Resource Center, and our online blockchain course is a great success with more than 45,000 enrolled and an average of 2,500 new enrollments per week.”

Hyperledger Blockchain Frameworks

In 2018, Hyperledger will start launching a number of frameworks and platforms that are currently in incubation.

“Interoperability in a multi-blockchain world will be the major focus in 2018. A number of Hyperledger projects are exploring integrations among one another including Hyperledger Sawtooth and Burrow and Indy, Composer and Quilt.”

Behlendorf expects that 2018 will also see some experimentation with different levels of permissioned access to blockchain networks.

He noted that permissioned and permissionless is more of a spectrum than a binary notion, and an important question is what the cost to join a node to a network is in any blockchain platform.

By reducing the cost of joining a networked ledger, Hyperledger hopes to enable new use cases and ways to solve problems.

“Hyperledger was started by a set of developers very focused on modest-sized permissioned ledgers, so that’s where the initial work has been, but there’s no hard limit to that. So we’re happy to look at options that make it easier, perhaps even to full permissionless frameworks,” said Behlendorf.

“I should note that our projects including Hyperledger Indy (for identity), Hyperledger Burrow (for smart contracts), Hyperledger Quilt (for interoperability) and Hyperledger Composer and Cello (developer tools) are agnostic about consensus mechanisms and would work fine with permissionless approaches,” he added.

Expect to see the following Hyperledger launches in 2018:

Quilt will offer interoperability between ledger systems by implementing ILP, which is a payments protocol designed to transfer value across distributed and non-distributed ledgers.

Sawtooth is a blockchain platform for creating and managing distributed ledgers. Sawtooth includes Proof of Elapsed Time (PoET) and a new consensus algorithm that is maintained without a central authority. It was originally proposed by Intel.

Iroha is a business blockchain framework for infrastructure projects that require the use of distributed ledger technology. It includes a chain-based Byzantine Fault Tolerant consensus algorithm. Soramitsu, Hitachi, NTT DATA and Colu originally proposed this framework.

Burrow is a smart-contract creator with a permissioned smart-contract interpreter included.

Indy is a distributed ledger with a decentralized identity designed to create independent digital identities between blockchains.

Composer is an open development tool set designed to make it easier to integrate existing business systems with the blockchain.

Cryptocurrency’s Red Tuesday Firesale Leaves Everyone Speculating

cryptomarket_sell-off.png

The cryptocurrency sky fell yesterday as 49 of the top 50 coins (by Market Cap) were down with only Tether (USDT) posting a gain. In fact, only two coins, KuCoin Shares and VeChain, showed losses less than 10 percent and only 12 of the top 50 have lost less than 20 percent of their value.

The effects of the market-wide shock are clear, but explanations vary based on where you get your news. In an effort to make sense of the situation, here are the stories and rationales explaining the systemic drop.

South Korea

Korean leadership this week has been fragmented on the subject of cryptocurrencies, causing a public backlash in a country that has enthusiastically embraced the new asset class.

On January 16, 2018, Yonhap News reported that the Prime Minister Lee Nak-yon stated, “What the justice ministry is going to do is not immediately shut down (exchanges) ... As this is a legislative issue, it is not possible to shut them down without going through the National Assembly.”

This seemingly contradicts a radio interview given earlier in the day by Korea’s finance minister, Kim Dong-yeon, who stated in a radio interview with TBS Radio, “The government stance is that it needs to regulate cryptocurrency investment as it is a largely speculative investment … The shutdown of virtual currency exchanges is still one of the options (that the government has).”

The perceived discord from top Korean officials is a carry over from January 11, 2018, reports where Justice Minister Park Sang-ki stated regulators were preparing legislation to halt cryptocurrency trading. Those statements were walked back by the presidential office (The Blue House) later in the day, when a spokesperson relayed that the government has not yet decided on shutting down cryptocurrency exchanges. This statement came a mere seven hours after the Justice Minister’s statements and after a petition to the presidential office gained viral support. This communicative disharmony doesn’t even address the raids on Korean exchanges Coinone and Bithump last week.

Bloomberg (which also cites China as a causal factor), New York Post, MarketWatch, and others have cited the latest actions today by South Korea as an inciting reason for the digital currency market-wide bloodbath.

China Threatens More Bans

Korean Leadership may not be the only source of consternation for the cryptocurrency market. Some media outlets, such as Quartz have pointed towards Korea’s much larger neighbor to the West, China.

China has had a tumultuous history with cryptocurrencies. In the past few months alone, the Central Bank of China banned ICOs in September 2017, followed by a January 2, 2018, leaked memo where the leading internet-finance regulator in the country, the Leading Group of Internet Financial Risks Remediation, called for an orderly exit of crypto-mining operations. The forced exodus of crypto-mining operations, according to TechCrunch, will slowly extinguish a group that is estimated to produce three-quarters of the world’s supply of bitcoin.

The final straw for the China thesis were reports on Monday, January 15, 2018, that the Chinese government is escalating its crackdown to include domestic cryptocurrency trading by planning to block access to online platforms, exchanges, market-makers and mobile application platforms that cater to Chinese citizens.

While Chinese citizens have in the past used VPNs to work around similar blocks to sites such as Google and Facebook, China has been determined to stem capital outflows from the country (and the government has ordered a crackdown of VPN usage starting next month).

Cryptocurrencies have provided the potential for unregulated outflows of capital from the mainland, so it seems that the cryptocurrency facilitators in China may face a different fate than their internet counterparts.

The U.S., Brazilian, Indian, French, German Regulator Effect

Regulation is the name of 2018. If the regulatory issues out of South Korea and China were standalone examples, that may be enough to explain the sell-off. But other regulatory fears may have been increased by a flurry of announcements over the past week:

On January 12, 2018, U.S. Treasury Secretary Steven Mnuchin mentioned a working group comprised of multiple federal agencies had been formed to look into how to regulate cryptocurrencies.

That same day, Brazilian regulator CVM banned funds from buying cryptocurrencies.

On January 14, 2018, The Hindustan Times reported the Indian government has formed a committee to fast-track the country toward regulating the domestic cryptocurrency marketplace. In line with previous efforts by Indian Prime Minister Narendra Modi to demonetize lower denominated rupees last year, the committee was formed, according to The Financial Express, based on Indian authorities’ apprehension of illicit money being used to trade cryptocurrencies (colloquially referred to as “black money”).

On January 15, 2018, French Minister of the Economy Bruno Le Maire announced the creation of a working group with the purpose of regulating cryptocurrencies and appointed Jean-Pierre Landau, the former deputy governor of the Banque de France, to lead the group. Landau wrote an editorial piece for the Financial Times in 2014 titled “Beware the mania for Bitcoin, the tulip of the 21st century.”

Also on January 15, 2018, a board member for Germany’s Central Bank (Bundesbank), Joachim Wuermeling, called for effective regulation of virtual currencies on a global scale.

The Post-FOMO FUD Factor

The cause for the market wide plummet yesterday in cryptocurrencies could simply be a case of FUD (“Fear, Uncertainty, Doubt”) among new investors panic selling in the face of all of these regulatory actions or initiations by major world economies. Or perhaps it is entrenched investors taking regulatory actions as their signal to sell before regulations negatively impact their unrealized profits.

It may be a combination of events and speculation. The news reports differ on what events are emphasized depending on what coverage you look at (and if you look to John McAfee for causation, you’ll note the market drop was all because of J.P. Morgan spiking fears about potential government bans).

Regardless of the cause, the effects are clear. It now remains to be seen whether there will be a rebound or whether the sell-off will gain momentum as we look ahead to a future where regulatory impacts potentially curtail the bull-run the industry blossomed under in 2017.
