HiddenWallet and Samourai Wallet Join Forces to Make Bitcoin Private With ZeroLink

HiddenWallet and Samourai Wallet Join Forces to Make Bitcoin Private With ZeroLink

Ádám “nopara73” Ficsór, HiddenWallet developer and TumbleBit contributor, and “TDevD,” the pseudonymous Samourai wallet developer, are joining forces on a new privacy project: ZeroLink. ZeroLink is set to realize a trustless mixing scheme first proposed by Bitcoin Core contributor Gregory Maxwell years ago — but one that hasn’t been realized thus far.

According Ficsór, the ZeroLink framework, which utilizes a scheme known as “Chaumian CoinJoin,” is actually more straightforward than many of the alternatives that have been proposed.

“Back in 2013, there was this sort of obsession with decentralization. ‘Everything that can be decentralized will be decentralized’ was the slogan,” the developer recalls. “By now we realize that decentralization is actually not always that useful. As long as a mixer cannot steal funds or link transactions, that’s enough.”

CoinJoin

Each Bitcoin transaction essentially sends bitcoins from one or several Bitcoin addresses (really: “inputs”) to one or several Bitcoin addresses (really: “outputs”). That’s how bitcoins “move” over the blockchain.

The problem, from a privacy perspective, is that the blockchain is completely public, which means that anyone can see which addresses are paying which addresses. If these addresses can be linked to real-world identities, it can reveal a lot about who transacted with whom, and perhaps for what.

CoinJoin, the well-known coin-mixing scheme first proposed by Maxwell in 2013, is a potential solution to this problem. A CoinJoin transaction is basically a combination of several transactions merged into one big transaction. In other words, it includes inputs from several different users, and the bitcoins move to outputs controlled by several different users. As such, it’s not clear which bitcoins moved where. All users effectively paid all users.

While that’s great, the next problem is that whomever or whatever combines the different transactions into one CoinJoin transaction can be a central point of failure from a privacy perspective. That person (or that server, or whatever it is) still knows which bitcoins moved where. So if that individual is either corrupt or corruptible, the problem isn’t really solved.

“For CoinJoin to live up to its promise, even the entity that creates the transaction must not learn which addresses are paying which addresses,” Ficsór noted.

ZeroLink

ZeroLink provides a privacy framework for wallets that can be used for different mixing schemes. And it defines its own mixing technique as well: an implementation of CoinJoin referred to as “Chaumian CoinJoin.”

With Chaumian CoinJoin, users both send and receive equal amounts of bitcoin from a CoinJoin transaction, so everyone receives each other's coins. This obfuscates the trails for all of these coins.

In practice, ZeroLink users will require two types of wallets: a pre-mix wallet and a post-mix wallet. As the names suggest, the first type holds coins that are to be mixed, while the latter is where the mixed coins end up.

Users then connect their pre-mix wallets to the ZeroLink tumbler and provide an input (“from” address) and an output (“to” address), which they both control. But importantly, the outputs are disguised (“blinded”) using a mathematical trick. So while the tumbler knows where all bitcoins are sent from, it does not yet know where bitcoins are sent to.

At the heart of the trick, the tumbler then cryptographically signs all blinded outputs, using a type of cryptographic signature introduced by David Chaum: a “blind signature.” This allows data to be cryptographically signed even if it is disguised. And importantly, these signatures can be checked against the original, unblinded data as well to see if the blinded data and the unblinded data match.

Next, all users connect to the tumbler again, but this time through some type of anonymity network, like Tor. They will then provide the tumbler with the unblinded versions of the outputs. Using the cryptographic signatures it just created, the tumbler can check that all revealed outputs match all blinded outputs. If they do match, the tumbler knows that all the outputs it received are legitimate, and thus were provided by the same users that also provided the inputs to send funds.

The tumbler then adds the revealed outputs to the CoinJoin transaction. And it sends this transaction back to all users, for these users to sign with their Bitcoin private keys. Doing so validates the transaction. (The users should of course double check that the amounts and their outputs check out, to be sure they receive as much as they send.)

Finally, the tumbler broadcasts the CoinJoin transaction to be included in a Bitcoin block. As a result, all users end up with different bitcoins than they started with: all bitcoins were mixed, and the blockchain trails broken.

While all this is actually relatively straightforward compared to some alternative schemes, and to a large extent already suggested by Maxwell back in 2013, the process has never been realized. This is probably because it was long thought to be too vulnerable to attacks, Ficsór thinks.

“When Maxwell first published the proposal, Bitcoin transaction fees were practically non-existent. Because of this, it would be relatively easy and cheap to launch denial of service attacks against a CoinJoin mixing system. An attacker can just keep providing valid inputs, but refuse to sign when he should. That invalidates the whole transaction, and wastes everyone’s time.”

Interestingly, this attack vector is now to some extent resolved simply because it would be too expensive to keep it going. In order to maintain the attack in a way that it’s not easily countered, an attacker must provide new inputs for each round, meaning he must be able to keep moving bitcoins to new addresses to do so. “Assuming $1 transaction fees, that could cost up to $1,000 a day,” Ficsór pointed out. “In this particular context, high fees are a blessing in disguise.”

Development

Ficsór is currently about to help wrap up the development of another highly anticipated privacy tool, TumbleBit, for Stratis’s Breeze Wallet. This is expected to take another three months.

After that, he plans to focus on realizing ZeroLink, while TDevD may even start working on the framework sooner. Concretely, three new codebases need to be developed: the pre-mix wallet, the tumbler and the post-mix wallet.

“The tumbler needs to be developed from scratch. But it should be relatively easy to add the pre-mix wallets to any existing open source wallet. The same is true for the post-mix wallet implementations, though for privacy reasons not all wallets are a good fit,” Ficsór said.

His own HiddenWallet as well as Samourai Wallet are “fully committed” to implementing and deploying ZeroLink into production, Ficsór said, while Breeze Wallet may be interested as well.

Optimistically, an initial implementation of ZeroLink could be live before the end of this year.

For more information on ZeroLink, see Ficsór's blog post on the project (which also includes a donation address) or ZeroLink’s specification.

Bitcoin Price Analysis: Long and Short Squeezes Shape a Weakening All-Time High

Bitcoin Price Analysis

This morning, BTC-USD pushed a new all-time high on several exchanges. However, this time, the momentum to continue higher seems to be waning. Shortly after establishing the new all-time high, there was a $150 flash crash that sprang a series of account liquidations across several exchanges in a move that would ultimately “long squeeze” the market. A long squeeze is a term used to describe the sudden cascade of long positions getting stopped out of their positions, causing market orders to propel the price even lower:

Figure_1 (1).JPGFigure 1: BTC-USD, 5-Minute Candles, Bitfinex, Long Squeeze

The figure above shows the price movement correlated to the volume during the $150 drop. Halfway through the drop we see a sudden spike in sell volume. This spike in volume is the beginning of the “long squeeze” that initiated the cascade of market sell orders caused by traders in long positions being forced out of their positions via their stop-loss market orders.

Figure_2 (1).JPGFigure 2: BTC-USD, 15-Minute Candles, Bitfinex, Short Squeeze

Yesterday, at around 12 pm EST, the exact opposite thing happened in a market event known as a “short squeeze.” You can think of a short squeeze as literally the opposite of a long squeeze: People who are anticipating a great short entry are suddenly forced out of their positions via their stop-loss orders, and market buy orders propel the market higher, thus triggering more stop-loss orders until the market equalizes.

Today the BTC-USD market has begun a series of long squeezes that pulled the price down by $300 in a matter of hours, and it doesn’t show much sign of letting up at the moment. Let’s take a look at the macro trend and see where the market is likely heading:

Figure_3 (1).JPGFigure 3: BTC-USD, 3-Day Candles, Bitfinex

For the fifth candle in a row, the 3-day candles have managed to puncture the Bollinger Bands in a move that indicates an overbought market. We have yet to see an attempt to move within the Bollinger Bands and provide some relief for the high price range.

Zooming in a little closer, we can see that clear signs of bullish exhaustion formed as we began to push the most recent set of all-time highs:

Figure_4.jpg
Figure 4: BTC-USD, 2-Hour Candles, Bitfinex, Bullish Exhaustion

The first thing that pops out about this trend is the decrease in volume (shown in pink) leading into this morning’s all-time high. Upon reaching that high, sell volume began to pick up considerably (labeled in blue) and has continued to remain strong during the push into the $4300 and $4200 prices. The previous all-time highs (labeled in yellow) are currently paired with a decreasing MACD moving average/signal line trend that indicates the market is losing bullish momentum across the macro trend.

The BTC-USD market seems to be running on fumes at the moment, but I would not  be surprised at all to see an all-time high squeezed out of this market. However, I would be VERY surprised if that all time had any notable follow-through. The market volume on the macro levels has steadily declined, and there are key market indicators that hint toward the need for sustained sideways consolidation. Alternatively, a strong market pullback might be in the cards for BTC-USD. Each push toward the new highs has been greeted by strong sell volume. In the event of a market retracement, your key support levels on the macro exist along the Fibonacci Retracements shown below:

Figure_5.JPGFigure 5: BTC-USD, 4-Hour Candles, Bitfinex, Key Support Levels

When the market begins to struggle to push new all-time highs, it is important to keep a close eye on the volume and see how it interacts with the price movement. Consistent price growth on decreasing buy volume is a signal that the bears, although losing the battle in price currently, are gathering as the market nears its final top before ultimately correcting or consolidating. And given the price growth over the past 30 days, I would be inclined to lean toward the former rather than the latter.

Summary:

  1. Short squeezes and long squeezes have begun to shape the current market trend.

  2. On the macro and micro scale, the market is showing a highly overbought market and is beginning to lose upward steam.

  3. Key support levels lie on the Fibonacci Retracements shown in Figure 5.

Presearch Uses Ethereum Blockchain and AI to Challenge Google on Its Own Turf

Presearch Uses Ethereum Blockchain and AI to Challenge Google on Its Own Turf

Presearch, a software development startup specializing in information search engines, is challenging Google on its own turf with a double-barreled approach, using both blockchain technology and AI.

Presearch’s search engine, already in use internally since 2013, is launching in beta this September. Blockchain technology and AI will be supplemented with curation by subject matter experts.

Founder and project lead Colin Pape, who previously launched the e-commerce site ShopCity.com, said:

“While Google is generally thought of as a neutral entity for search, the company answers to Wall Street and operates very secretively.

“They’ve become known for promoting themselves at the expense of alternatives and appropriating others’ information, blaming it on ‘the algorithm.’ The reality is that they manipulate results and justify changes as being best for the user.”

Pape wants to provide a community-driven, decentralized, open and transparent alternative to Google, in contrast to what he calls the “manipulated algorithm-driven methods standard among today’s industry giants.”

Pape told Bitcoin Magazine:

“Presearch will use a combination of human curation by subject matter experts who are rewarded with tokens, and machine learning technology and APIs from other search providers (particularly for long-tail searches).”

Pape told us they will be using the Ethereum Blockchain ERC20 standard to start but may build their own blockchain technology at some point down the road.

Openness, Accountability and Community Participation

The company’s white paper emphasizes that never in the history of the world has so much information been concentrated in so few hands. It also points out that Google makes $100 billion in annual revenue from search engine searches.

Presearch estimates that 77 percent of global desktop searches and 96 percent of mobile searches, more than 5 billion queries per day, go to Google.

The white paper states that Google has built up an unprecedented degree of trust with users with “their simple interfaces, lightning-fast response times and utter reliability, combined with what appear to be amazingly accurate results.”

A Search Engine Wikipedia

Presearch believes that a decentralized, community-based decision-making process ensures everyone’s interests are considered. By rewarding members for using, promoting and contributing to the Presearch platform, the company wants to create a scalable “Wikipedia for search” to allow members to curate the best content for each inquiry.

The Presearch community can also vote on and fund new development projects, continually upgrading the platform.

Pape added: “With Presearch, I wanted to flip that business model on its head and put power over information back into the hands of all internet users.”

Search is the gateway to the web. The world deserves an alternative search engine that is open, transparent, and that involves the community in product development, consensus and quality control.

Funding

Presearch’s curation and overall development of the platform is incentivized with the Presearch Token (PST).

Presearch has run three separate crowd sales for $1 million, $1.5 million and $3 million in token revenue. There are three more sales to go that are targeted to generate more than $30 million in total revenue.

The startup is headquartered in Midland, north of Toronto, Canada. A “distributed” team is located in Silicon Valley, Boulder, Colorado and the Atlanta area, and the company is planning to expand internationally.

Advisors to Presearch include internet innovator, Rich Skrenta, who sold his search engine Blekko to IBM Watson; open-source search innovator Trey Grainger, SVP of Engineering at Lucidworks; and technology lawyer Addison Cameron-Huff, whose experience includes working with Ethereum’s founding team.

Bitcoin Magazine contacted Google for comment but has not yet received a response.

Blockchain and Bitstamp Customers Can Now Use Ether

Bitstamp and Blockchain add ether

Ethereum fans got a bit of a boost today from two different companies in the crypto space. UK-based cryptocurrency firm Blockchain and Luxembourg-based cryptocurrency exchange Bitstamp have each added ether to their platforms for the first time.

Blockchain says its customers can simply toggle between bitcoin (BTC) and ether (ETH) to manage and transact funds quickly and easily. Additionally, Blockchain has also integrated ShapeShift’s API so trading bitcoin to ether and vice versa can happen all from one place.

In an earlier, separate announcement to its customers, Bitstamp said it will allow full trading functionalities of ether today. Ether deposits and withdrawals opened at 9 am (UTC) and began to allow full trading functionalities at 1 pm (UTC).

Nejc Kodrič, CEO of Bitstamp, said: "We've been encouraged by ether's potential and the demand shown for its inclusion among our trading pairs.”

Ether now joins USD, EUR, bitcoin, litecoin and Ripple among the coins for which Bitstamp allows deposits and withdrawals. In July the company announced a strategic partnership with Swissquote, the Swiss leader in online banking. Swissquote launched BTC/EUR and BTC/USD trading on its platform, with Bitstamp providing full-stack services for their two new BTC trading pairs.

Kodrič added: ”Since starting out in 2011, Bitstamp's mission has been to be the safest and most reliable digital currency exchange on the market. Our careful approach has created a market reputation for prudence which has served us well as we continue to expand and give our customers the trading options they desire."

Peter Smith, CEO of Blockchain, said in a statement that the popularity of Ethereum has grown and so has the desire from Blockchain customers to have the option to manage multiple digital assets within their Blockchain wallets. Smith said: “We are thrilled to introduce this new functionality to our community and will continue to find ways to make interacting with digital assets even easier.”

One of the earliest bitcoin companies, Blockchain was founded in 2011 and provides a non-custodial consumer wallet for digital assets, with over 16 million wallets created across 140 countries. The company has focused on creating products that make storing, transacting and hedging digital currency a frictionless experience.

Smith was recently quoted saying: “I predict that by 2037 a complete global computer fabric will make interacting with goods, services and people easier than ever. Citizens of the world will be more closely connected through technology, communication and networks."

Second in market cap, ether has seen its price soar as much as tenfold since the end of April, while its number of transactions quadrupled. Ether has since settled at about $300 at the time of publication.

Crypto Exchange Shapeshift Acquires KeepKey Hardware Wallets

ShapeShift Acquires KeepKey

Today, Shapeshift.io announced its acquisition of hardware wallet manufacturer KeepKey. According to the cryptocurrency exchange, by pairing the KeepKey hardware wallet with ShapeShift, users will be allowed to safely store their coins on a secure physical device while trading their assets directly over the ShapeShift API, which can be reached from KeepKey’s interface.

“Security is of critical importance when it comes to holding and trading digital assets. One of our priorities has always been to make the exchange experience as safe and easy for users as possible, and our pairing with KeepKey enables us to provide an unmatched customer experience. Users can hold their coins on the hardware device and exchange them on demand within the wallet, without even visiting a website. When you pair the KeepKey hardware wallet with ShapeShift’s exchange, the experience is magical,” Erik Voorhees, CEO of ShapeShift, said.

KeepKey already had integrated ShapeShift’s API a year ago, allowing it to supporting the most popular cryptocurrencies. The firm’s objective is to support all leading digital assets providing the users with the “most secure storage wallet available.”

“This partnership will not only guarantee the future success of the KeepKey brand and product line, but joining the ShapeShift team will enable us to focus on continuing to work on developing better technology and security for crypto-holders,“ said Ken Hodler, Chief Technology Officer at KeepKey.

ShapeShift confirmed that the company will preserve KeepKey’s brand and product line. Furthermore, the acquisition of KeepKey will allows ShapeShift to “provide increased capital for inventory and security expertise.”

“Amid heightened interest in the concept of digital currencies, a simple, user-friendly cold storage wallet with native exchange functionality is one key to wider adoption,” said Voorhees.

The combination of ShapeShift and KeepKey reflects both companies’ commitment to security and privacy. ShapeShift does not collect any personal information on its users. Furthermore, customer funds are not collected on the company accounts and users maintain control of their keys at all times.

The KeepKey drive is physical hardware device that protects users’ funds from “hackers and thieves.” It uses wallet software located on the user’s computer. The device takes over the management of private key generation and storage along with the signing of transactions. The hardware has a built-in random number generator for private keys, which works in combination with the “randomness” provided by the user’s computer. After the private key is generated, the user is given a twelve-word recovery sentence, which can be used to recover the device without compromising its private keys.

Weber, research consultant at Bank of Canada who is also a visiting scholar at the Federal Reserve Bank of Atlanta and adjunct professor at the University of South Carolina, speculated about a financial system where bitcoin would be the standard currency (referred as the “Bitcoin standard”) instead of fiat currencies.

In the study, Weber explored the similarity between the Bitcoin standard and the gold standard. The research consultant chose to compare bitcoin to gold since the two have many similarities. The two most prominent resemblances include the lack of control of central banks or monetary authorities and the limit in the supply: Bitcoin’s algorithm only allows the circulation of 21 million BTC while gold can be found in finite quantities on the planet. If the Bitcoin standard becomes real, there will be three distinct media of exchanges, just as there was under the gold standard. Bitcoin will serve as the main currency while there will be fiduciary currencies issued by countries’ central banks, and fiduciary currencies (banknotes or deposits) issued by commercial banks.

Issuing fiduciary currencies will be one of the very few abilities central banks can do as part of a monetary policy where banks will act as lenders of last resort. Bitcoin’s “virtually costless arbitrage” on an international scope will deprive the central banks of their ability to impose interest rate policies to affect their domestic economies, Weber detailed.

Should Bitcoin serve as the standard medium of exchange, there would be a moderate increase in deflation; however, according to Weber, once a certain level is reached, the rate of deflation will be minimal. Price levels will become highly or perfectly correlated under Bitcoin’s dominance in various countries, just as they did for those countries that adopted the gold standard. Despite the fact that the cryptocurrency would become the standard, Weber believes that economic crises could still happen since “they can occur under any fractional reserve financial system.”

According to Weber, the Bitcoin standard will benefit the economy in two ways. Due to the “known, deterministic rate” at which new BTC is created, people would be able to predict the price level of the cryptocurrency more easily. The second benefit would be that investment resources which are currently devoted to hedging against fluctuations in the currency exchange rates would free up and could be used in “more productive ways.”

On the other hand, Weber thinks that the Bitcoin standard will never come into existence since there will be heavy opposition by central banks and governments. If the Bitcoin standard becomes real, neither the governments nor the central banks will be able to implement interest rates to affect their economies, neither could they generate seigniorage revenues obtained from their ability to “almost costlessly create money,” the Bank of Canada research consultant explained. Since the governments don’t want to lose these powers, they will do anything to prevent Bitcoin from becoming the standard medium of exchange.

Weber is also skeptical about the longevity of the Bitcoin standard. According to him, the financial system is advancing so rapidly that there would likely be another (crypto)currency that can provide the same or greater benefits as Bitcoin, possibly at lower costs. Furthermore, if a financial crisis occurs, an opposition is likely to emerge that would seek to replace the “old” financial system, rather like the way that Bitcoin is challenging today’s status quo.

Blockstack Partners with VCs to Launch $25 Million Blockstack Signature Fund

New York-based decentralized internet and developer platform Blockstack has partnered with a number of venture capital groups to launch the $25 million Blockstack Signature fund.

The Blockstack Signature fund is backed by Lux, OpenOcean, VersionOne, RisingTide, and Compound, and funding will go toward apps being built in the Blockstack ecosystem.

Patrick Stanley, growth partner at Blockstack, explained to Bitcoin Magazine that “Blockstack is not launching the VC fund but facilitating.” That is, the company’s role in the fund has been to gather the venture capital groups, attract the developers and facilitate the partnerships that will result in quality app development on the Blockstack platform.

According to Blockstack, the VC fund will dedicated to “rapidly accelerating startups building decentralized applications on the platform, and tools for developers to bootstrap their apps, with tokens on the Blockstack network — just like you see with Ethereum.”

Muneeb Ali, co-founder at Blockstack, told Bitcoin Magazine: “We are at a stage where some of the developers are incredibly excited about building apps and usually get in touch with us. If developers get in touch with us with an app that they are excited about, this is one funding channel we can point them to.”

Ali added: “The VCs involved in the fund will take a look at that application and make a independent decision to fund that company or now. Our intention here is to bring together sophisticated investors, people who have been thinking a lot about decentralization and can do their due diligence.”

VC investing is a type of private equity, a form of financing that is provided by firms or funds to small, early-stage, emerging firms that are deemed to have high-growth potential, or which have demonstrated high growth in terms of number of employees, annual revenue or both.

Ali explains: “If you look at this space in general we feel that there are a lot of low quality apps which are raising an insane amount of capital from token sales, for example. We want to bring some quality and sanity to the picture. We feel that VCs can still have a seat at the table … we want to open up that channel as well.”

Blockstack was formerly known as Onename and passed through its young company status in the summer of 2014 as a startup looking to streamline bitcoin transactions.
