Senators Call For Digital Currency Oversight In Anti-money Laundering Bill - Coindesk

Senators Call for Digital Currency Oversight in Anti-Money Laundering Bill A pair of US senators have filed a new anti-money laundering bill aimed at beefing up oversight of digital currency activities. The bill the Combating Money Laundering, Terrorist Financing and Counterfeiting Act of 2017 was filed last week by Senator Chuck Grassley of Iowa and Senator Diane Feinstein of California. Among the changes, according to a draft text of the bill, are additions to definitions for "financial institutions", which, if the bill is passed, would include "any digital currency exchanger or tumbler". Additionally, the bill clarifies that any "issuer, redeemer or cashier" of a "digital currency" is also covered. While not explicitly spelled out as such, the bill moves bitcoin and other digital currencies closer to being defined as a "monetary instrument" under US anti-money laundering statutes, as it targets "funds stored in a digital format", according to a summary published by Grassley's office. Beyond the regulatory adjustment, the bill seeks information from the US Department of Homeland Security's Customs and Border Protection (CBP) agency about its policies on digital currencies. Specifically, it calls for a report "detailing a strategy to detect prepaid access devices and digital currency at border crossings and ports of entry". This report which would be due 18 months after the ostensible passage of the bill is also required to include details about how such a strategy would be implemented. The bill's releasecomes shortly after a member of the US House of Representatives called for a study into virtual currency use for terrorism financing. A full copy of the bill can be found below: Continue reading >>

How Crypto Price Is Controlled By Dark Markets

How Crypto Price Is Controlled By Dark Markets

You hear stories like that all the time someone bought, mined, or get payed in Bitcoins in 2011, dumped old computer, and then bam! the coins are worth 4 000 $ each in 2017. There is no use crying over spilled crypto milk very few saw that coming. But what caused such massive cash influx into Bitcoin? Why it makes USDs the backbone of the fiat financing seem like a worthless peace of paper? Is BTC just a bubble? There is a answer that no one talks about. Dark markets are Tor-powered, anonymous libertarian marketplaces, offering everything you cant buy in Walmart stolen IDs, cards, drugs, guns, pirated content. In general dark markets are ultra secure and anonymous, because the payments in crypto are anonymous thanks to tumblers or mixers, that basically use coinjoin protocol to launder cash. But most of the time FBI manages to find a way to either DDoS or shed a light on one or two markets each year. The first mainstram market Silkroad was founded by a pro-free-economy Ross Ulbricht aka Dread Pirate Roberts. By the way, do you know what blew his cover? He loved his nickname frosty too much. The Silk Road gathered over one million users and USD 1.2 billion in sales. Lets see whether we can connect the dots. Silk Road peak popularity was in 20122013. Here is a scrutiny of Silk Road operations partly courtesy of Ross Ulbricht trial, during which all BTC addresses were uncovered. Here is a chart from 2012 representing Silk Road development: And here is a Bitcoin price chart at that time: Source: Carnegie Mellon University analysis of SilkRoad As you can see, the figures correlate proportionally. Bitcoin derived its worth from utility as a currency in a place where traceable fiat currencies were unusable. But Bitcoin is clumsy now it is slow and expensive to transact.

Zcoin Develops Decentralized Mixer For Ethereum

Zcoin Develops Decentralized Mixer For Ethereum

Zcoin develops decentralized mixer for Ethereum The Zcoin team is in the process of creating a new type of so-called mixers or tumblers, which are servers used to mix the funds of some users with those of others enough times to make it impossible to trace their origin. The big difference is that this mixer will be specially designed for implementation in smart contracts, and does not actually require other users or a centralized server - a third party - to achieve its goal. While in services such as Bitcoin Fog the user must transfer their funds to a hidden server that may not give him the answer he expects, and also depends on the liquidity provided by other users so that their numbers are mixed; With Zcoin's mixer what happens is that the owner of the funds, after depositing them into a contract, receives anonymous tokens that mingle with the ethers in the transfers, thus protecting their true origin within the same decentralized platform of Ethereum. Although for now this idea is under construction, according to its official page, from Zcoin are working together with Vitalik Buterin for a possible implementation in Metropolis, the next hardfork of this blockchain, which plans to update it during the next months to offer much more security, scalability and privacy. On the other hand, this is not the only option considered by the developers of Ethereum to increase the anonymity of their transactions. The first to be considered was the zero knowledge protocol of Zcash, with which they are still collaborating for the same purpose. In fact, this new alternative is surprising, given that Zcoin is well below Zcash in terms of market capitalization and value per unit. Continue reading >>

Bitcoin Tumbling: How Zerolink Will Hide Your Coins

Bitcoin Tumbling: How Zerolink Will Hide Your Coins

Bitcoin is often viewed as an anonymous currency. People are often of the view that their transactions could never be traced nor their identities confirmed. Although Bitcoin addresses are anonymous, all transactions on the blockchain can effectively be traced using blockchain audits . There are companies such as Chainalysis which specialise in tracking the flow of Bitcoin funds. Therefore, the moment that someone tries to take the coins onto an exchange in their name, they have effectively de-anonymised themselves. This is exactly how the hacker who stole coins from Mt Gox was identified. You may then be wondering how you can effectively anonymise your coins and break a link in the chain? That is where transaction mixers come in. The Bitcoin protocol was developed such that all transactions are placed on a public and immutable ledger called the blockchain . Unlike privacy conscious coins such as Monero and Zcash , your public address and the funds that flow to it are recorded on this public blockchain. However, if you are able to mix the coins that you have with a number of other addresses, you are effectively obfuscating the origin of the coins. Think of it as one large pool where everyone will insert their coins. The tumbler will mix the coins through a number of runs and then send the coins back to the owner. Given that the coins were mixed with a whole bunch of other coins, it would be nearly impossible for someone to trace your coins once they have come out of the tumbler. ZeroLink is a CoinJoin tumble service that was developed by Adam Ficsor and is about to launch in a few days. As part of the introductory offer, the developers are holding a live test on the Bitcoin network with beta testing subjects. In order to make the most of the tumbling test, they need bet Continue reading >>

[ann] Privcoin.io Mixing Service For Ethereum, Litecoin, And Bitcoin Cash

Sorry to come late to the party! I have never needed to consider any other mixing service since I started using one recently, as I chiefly only need to add privacy to my Bitcoins. However, with considerable amounts of my crypto portfolio will now almost permanently in alts, including Litecoin and Ethereum, I am looking to a mixer that supports these too. I will probably not start mixing until next year, if at all, depending a lot on what happens with the market, but better to start preparations early. Question for Privcoin: you say you are the most advanced. Can you explain how? P.S. Let us compare to one of the best out there that has now closed down (bitmixer).

Bitcoin Privacy For All: Breeze Wallet Is About To Bring Tumblebit To Life

Bitcoin Privacy For All: Breeze Wallet Is About To Bring Tumblebit To Life

TumbleBit, one of the most promising privacy advancements built on top of Bitcoin, will be implemented in the upcoming Breeze Wallet. The Breeze Wallet is a bitcoin wallet in development by blockchain startup Stratis , scheduled for release in one or two months. It will serve as a typical bitcoin wallet for desktop computers, but with an added tumbling option. Connected through a TumbleBit tumbler, Breeze Wallet users can mix their coins without needing to trust each other or the tumbler with their coins or their privacy. We are integrating TumbleBit because its a trustless and secure solution that works with Bitcoin without any forks, Stratis Founder and CEO Chris Trew told Bitcoin Magazine. Stratis is a U.K.-based startup that offers end-to-end solutions for development, testing and deployment of blockchain applications. The company will maintain its own blockchain (the Stratis blockchain), which includes a native token (the Stratis token). Additionally, the company builds tools for existing blockchains, including Bitcoin, Ethereum and BitShares. Stratis projects include a Bitcoin full node in the programming language C#, a Bitcoin software development kit and, indeed, the Breeze wallet, which will hold both bitcoins and the Stratis tokens. TumbleBit was first proposed by academic researchers Ethan Heilman, Leen AlShenibr, Foteini Baldimtsi, Alessandra Scafuro and Sharon Goldberg. Inspired by its potential, Programming The Blockchain in C# author and Stratis team member Nicolas Dorier started working on an implementation of TumbleBit in C#. He was joined by the co-author of his book, Ficsr dm, who focused on Tor integration. Now, with the help of dm, Stratis is making the solution available in a convenient and easy-to-use wallet. It is a natural match not only becaus Continue reading >>

Cryptocurrency Tumbler

Cryptocurrency Tumbler

Cryptocurrency tumbler or cryptocurrency mixing service [1] is a service offered to mix potentially identifiable or 'tainted' [2] cryptocurrency funds with others, so as to obscure the trail back to the fund's original source. [3] Tumblers have arisen to improve the anonymity of cryptocurrencies, usually bitcoin (hence Bitcoin mixer), since the currencies provide a public ledger of all transactions. Currently (2015) there is only one service which offers tumbling of multiple cryptocurrencies, PrivCoin. [4] [5] In traditional financial systems, the equivalent would be moving funds through banks located in countries with strict bank-secrecy laws, such the Cayman Islands , the Bahamas , or Panama . Tumblers take a percentage transaction fee of the total coins mixed to turn a profit, typically 1-3%. [6] Mixing helps protect privacy and can also be used for money laundering by mixing illegally obtained funds. Mixing large amounts of money may be illegal, being in violation of anti-structuring laws. Financial crimes author Jeffrey Robinson has suggested tumblers should be criminalized due to their potential use in illegal activities, specifically funding terrorism ; [6] however, a report from the CTC suggests such use in terrorism-related activities is 'relatively limited'. [7] There has been at least one incident where an exchange has blacklisted "tainted" deposits descending from stolen bitcoins. [8] The existence of tumblers has made the anonymous use of darknet markets easier and the job of law enforcement harder. [9] Peer-to-peer tumblers appeared in an attempt to fix the disadvantages of the centralized model of tumbling. These services act as a place of meeting for bitcoin users, instead of taking bitcoins for mixing. Users arrange mixing by themselves. This model sol Continue reading >>

Mitigating Blockchain Analysis: Mixing Cryptocurrency

Mitigating Blockchain Analysis: Mixing Cryptocurrency

Mitigating Blockchain Analysis: Mixing Cryptocurrency Get the latest security news in your inbox. Cryptocurrency is a digital currency, and it comes in many forms, built upon varying Blockchain technologies. Bitcoin is the original cryptocurrency, created in 2009 by cypherpunk Satoshi Nakamoto. Since then, many new alternative cryptocurrencies have been created, popular alternatives are Litecoin, Ethereum, and Monero. when he said that cryptocurrencies are a dream for privacy and freedom lovers because they restore transacting power back to whom it belongs individuals who have a right to control their own money. While cryptocurrency is a great advancement for a cypherpunks dream of privacy, it still comes with its own set of flaws that allow for deanonymization through Blockchain analysis and off-chain analysis. Bitcoin is often thought to be an anonymous solution for digital transactions, but this simply is not true. Every time a transaction is made, the technical details of said transaction becomes a public record on the Blockchain. The Blockchain is a public ledger that holds a history of all transactions ever made, thus leaving the potential for analysis of said transactions. More recently, The Bitfury Group released a whitepaper for their new Blockchain analysis algorithm with the goal of identifying the users behind digital transactions, dubbing their deanonymization solution as a Bitcoin clustering algorithm. Bitcoin address clustering is self-described as a process that exposes bitcoin users by determining which addresses belong to a single user through an analysis of Blockchain data. The act of clustering groups those addresses together, enabling investigators to link them to a single entity.

Anonymity - Is There Any Ether Mixer / Tumbler Available? - Ethereum Stack Exchange

Anonymity - Is There Any Ether Mixer / Tumbler Available? - Ethereum Stack Exchange

Is there any Ether mixer / tumbler available? Quick checking around there are exactly two references to an Ether Mixer - this non functioning and here (r/ethereum) 24 days ago. Unless I am missing something how can I hide the source of an ETH transfer? I have a couple of Genesis block pre sale accounts. I want to send a handful to this new Daemon DAO for the hell of it. What I don't want is anyone to trace and see it all the way back to my mega stack in my pre sale account. Or is there only ETH -> BTC -> Mixing -> ETH and then send it? Would Shapeshift work in this fashion? ETH to them, goes where ever, they convert it on their account, send me the BTC to my virgin account, send back to buy ETH, receive in virgin ETH account, then send to the Daemon DAO? I do think I am missing something somewhere. P.S. I don't have any BTC and don't have money to buy it just for this, I do have lots of ETH. I recently proposed a protocol for decentralized ether mixer. But it has some non-trivial assumptions. Yaron Velner Sep 8 '16 at 8:23 Theoretically you could make an Ethereum mixer but I don't think it would be productive. This stems from 2 major flaws with mixers. Mixers aren't truly anonymous it obfuscates data but with enough computing power it can be decoded. You're spending a lot of Ethereum on transactions when you don't need to. This is true with Bitcoin as well where mixers end up costing 2%-3%. In my opion the best way to 'clean' ethereum or bitcoin if you want to is to use a site like ShapeShift and change your ethereum into Monero (a crypto specializing in anonymity). Move that Monero to a second wallet and then transfer it back out (possibly through a second website to avoid timing attacks). The costs of these transactions are minimal compared to the costs of mixing. Et Continue reading >>

Europol And Interpol Agree To Take Action Against Digital Currency Mixers/tumblers

Europol And Interpol Agree To Take Action Against Digital Currency Mixers/tumblers

In particular, the participants agreed to : Increase information sharing in the field of money laundering and digital currencies through the use of channels such as Europol, INTERPOL, the Egmont Group and FIU.net. Regulate digital currency exchangers and wallet providers under current anti-money laundering and counter-terrorism financing legislation in line with obligations already pending with the financial sector. Adopt a clear definition of concepts such as cryptocurrencies, digital currency exchanger, wallet provider and mixer for them to be included in the EU legal framework. In addition, the enforcement agencies voiced their intentions to take action against digital currency mixers/tumblers. The latter are designed to anonymise transactions, which burdens the work of law enforcement agencies to detect and trace suspicious transactions. With cryptocurrencies increasingly used to finance criminal activities including terrorism, Europol aims to continue to coordinate across EU Member States and beyond in an effort to effectively respond to this rising threat. In July 2017, two of the largest criminal Darknet marketplaces, AlphaBay and Hansa, which had accepted Bitcoin, Monero, and Ethereum, were shut down with the support of Europol. In addition, Europol has carried out specialised training to assist law enforcement in identifying organised crime networks within the Darknet and their use of cryptocurrencies. Many European countries remain vigilant when it comes to cryptocurrencies. Earlier this week, the Dutch central bank ( DNB ) struck a cautious note with regard to Bitcoin and its likes adding, however, that it sees the technologies behind cryptocurrencies as promising. In a Position Paper, the Dutch regulator said that it does not see cryptocurrencies as posing Continue reading >>

Worlds Largest Bitcoin Tumbling Service Announces Sudden Shutdown

Worlds Largest Bitcoin Tumbling Service Announces Sudden Shutdown

Worlds Largest Bitcoin Tumbling Service Announces Sudden Shutdown Largest mixing service BitMixer shuts down in a matter of days, leaving users both puzzled and curious. Announcements motivated by ethical reasons to stop offering the service despite millions of dollars revenue. The largest mixing service has decided to shut down operations, citing the future of Bitcoin as a catalyst. While no links have been made official, users question possible pressure and dark market shops as a possible cause. One of the largest mixing services announced that it will stop operating just before delivering on that promise. Mixing Bitcoins is mainly touted as service to attempt greater privacy by anonymizing the funds to some extent. A user who forwards their funds to the mixer gets mixed Bitcoins from the pool that the mixing service owns and his own funds then enter the pools reserve, which then may subsequently be delivered to another user of the mixing service. Bitmixer.io made an announcement on the popular Bitcointalk forums stating: When we started this service I was convinced that any Bitcoin user has a natural right to privacy. I was totally wrong. Now I grasped that Bitcoin is transparent non-anonymous system by design. Blockchain is a great open book. I believe that Bitcoin will have a great future without dark market transactions. Privacy, and not aid to criminal activity, was the only service being offered by the mixing service The announcement suggests using other currencies to buy contraband on the dark markets - not Bitcoin. Dash and Zerocoin [now named Zcash] were pointed out, which as many users know have a greater depth of privacy than Bitcoin. Despite mainstream media blaming Bitcoin for the Silk Road during the 2013 bust, better-informed holders understand that Bi Continue reading >>

Cryptocurrency Monero Is Skyrocketing Thanks To Darknet Druglords | Wired

Cryptocurrency Monero Is Skyrocketing Thanks To Darknet Druglords | Wired

It's tempting to think of cryptocurrencies in terms of Bitcoinin part because many cryptocurrencies are Bitcoin derivations. Monero's fully its own entity, though. First outlined in an October 2013 whitepaper by the pseudonymous figure Nicolas van Saberhagen and called Cryptonote, another pseudonymous individual known only as "thankful_for_today" later coded those ideas into a currency called Bitmonero. When open-source coders on the Bitcointalk forum disagreed with thankful_for_today's directions for the currency, they forked it in 2014 to create Monero, whose name means simply "coin" in Esperanto. Its structure solves several key privacy vulnerabilities that dog Bitcoin, which despite its reputation for secret transactions has long been stuck in a strange privacy paradox. Unlike commercial services like PayPal, Bitcoin allows anyone to spend money online without providing identifying details. But if someone's Bitcoin address is linked with their real identity, any transaction from that address is entirely visible on the public blockchain, the accounting ledger that prevents fraud and forgery in the Bitcoin economy. Hiding those transactions requires taking extra steps, like routing bitcoins through "tumblers" that mix up coins with those of strangersand occasionally steal themor using techniques like "coinjoin," built into some bitcoin wallet programs, that mix payments to make them harder to trace. "If I pay my rent in Bitcoin, it wouldn't be that hard for the landlord to figure out how much money I earned if I don't take extra precautions," says encryption and cryptocurrency consultant Peter Todd. "Then they can decide whose rent to increase. Youre giving away information you don't want to make public." Monero not only bakes anonymity features into the cryptocurren Continue reading >>

How To Use A Bitcoin Mixer

How To Use A Bitcoin Mixer

Some argue that only hackers or criminals would need to be anonymous when using Bitcoin or any other cryptocurrency, but that's not true. There are many reasons to keep your transactions private, especially when dealing with large amounts. We don't usually display our bank records for everyone to see, mostly because we're afraid someone will alleviate us of our holdings or maybe we just want to surprise someone or avoid embarrassing invoices. Whatever your motives might be, privacy is a right that's ours to protect and take advantage of. Satoshi Nakamoto pointed out that we should use multiple addresses to preserve our privacy, due to the pseudonymous nature of Bitcoin. But even when using Bitcoin the way Satoshi intended, it may not be enough. Experts can trace services used, transaction history and patterns to identify where payments are made from or to, So, what should you do? Mixers will provide you with a certain amount of privacy, by mixing your coins with other coins previously sent or in their reserve and sending different coins to the address you specify. When looking at the blockchain, one will be able to see you sent your coins to a wallet. And that someone sent coins to the wallet you want them sent, there will be no connection between your wallet address and the one where you want your crypto delivered. Today we're going to show you how to use CryptoMixer, which is an established Bitcoin tumbler and has a transparent 2000 BTC reserve that can be followed here, here and here. Cryptomixer has also been improved when compared to older mixers, since it will never mix your new coins with your old ones and it does not require you to register an account. There are also downsides associated with using tumblers, such as fungibility. Since anyone can deposit Bitcoin Continue reading >>

Huge Ethereum Mixer Cyberlog

Huge Ethereum Mixer Cyberlog

68% of total Ethereum transaction value controlled by one system UPDATE: We have released the Jupiter notebook on Github so that anyone can repeat the analysis done. Analyzing the Ethereum transactions, cyberFund has come across a finding that struck us so much that we rushed to dig deeper into this issue. We now wish to share our findings with a community hoping to come up with an explanation together. The clusterization of all Ethereum addresses from the inception of Ethereum until 15.09.2017 revealed a class of addresses that we will call in this paper temporary. These are addresses where funds come and leave within a short time interval no longer than 1 hour, after which the addresses are never used again. The temporary addresses constituted 46% of all active addresses and processed 65% of total transaction value during the analysed period. Analyzing transactions where these addresses were involved, we managed to collect piece by piece a full picture of what was going on: In the centre of the picture above, one can see a core of the Mixer which consists of more than 95% of temporary addresses. This core interacts with a group of shell addresses, or a shell layer, which includes both permanent and temporary addresses. The shell layer in its turn receives ETH from what we will call input addresses and sends ETH to output addresses displayed left- and right-hand on the scheme respectively. We looked up the names of the owners of these addresses in Etherscan. Only a few of these addresses had a name of the owner attached to them on Etherscan . The other names displayed on the picture above are the names mentioned in users commentaries on Etherscan, so we can only assume that they are the real owners of these addresses. In the end, it turned out that the total amount tr Continue reading >>
