Detecting Roles of Money Laundering in Bitcoin Mixing Transactions: a Goal Modeling and Mining Framework
ORIGINAL RESEARCH published: 06 July 2021 doi: 10.3389/fphy.2021.665399 Detecting Roles of Money Laundering in Bitcoin Mixing Transactions: A Goal Modeling and Mining Framework Mingdong Liu 1, Hu Chen 2 and Jiaqi Yan 3* 1School of Economics and Management, Southeast University, Nanjing, China, 2School of Software Engineering, South China University of Technology, Guangzhou, China, 3School of Information Management, Nanjing University, Nanjing, China Cryptocurrency has become a new venue for money laundering. Bitcoin mixing services deliberately obfuscate the relationship between senders and recipients, making it difficult to trace suspicious money flow. We believe that the key to demystifying the bitcoin mixing services is to discover agents’ roles in the money laundering process. We propose a goal- oriented approach to modeling, discovering, and analyzing different types of roles in the agent-based business process of the bitcoin mixing scenario using historical bitcoin transaction data. It adopts the agents’ goal perspective to study the roles in the bitcoin money laundering process. Moreover, it provides a foundation to discover real- world agents’ roles in bitcoin money laundering scenarios.

Bitcoin Tumbles As Miners Face Crackdown - the Buttonwood Tree Bitcoin Tumbles As Miners Face Crackdown
6/8/2021 Bitcoin Tumbles as Miners Face Crackdown - The Buttonwood Tree Bitcoin Tumbles as Miners Face Crackdown By Haley Cafarella - June 1, 2021 Bitcoin tumbles as Crypto miners face crackdown from China. Cryptocurrency miners, including HashCow and BTC.TOP, have halted all or part of their China operations. This comes after Beijing intensified a crackdown on bitcoin mining and trading. Beijing intends to hammer digital currencies amid heightened global regulatory scrutiny. This marks the first time China’s cabinet has targeted virtual currency mining, which is a sizable business in the world’s second-biggest economy. Some estimates say China accounts for as much as 70 percent of the world’s crypto supply. Cryptocurrency exchange Huobi suspended both crypto-mining and some trading services to new clients from China. The plan is that China will instead focus on overseas businesses. BTC.TOP, a crypto mining pool, also announced the suspension of its China business citing regulatory risks. On top of that, crypto miner HashCow said it would halt buying new bitcoin mining rigs. Crypto miners use specially-designed computer equipment, or rigs, to verify virtual coin transactions.

Additionally, he said this is part of China’s goal of curbing speculative crypto trading. As result, bitcoin has taken a beating in the stock market. -

Bypassing Non-Outsourceable Proof-Of-Work Schemes Using Collateralized Smart Contracts
Bypassing Non-Outsourceable Proof-of-Work Schemes Using Collateralized Smart Contracts Alexander Chepurnoy1;2, Amitabh Saxena1 1 Ergo Platform [email protected], [email protected] 2 IOHK Research [email protected] Abstract. Centralized pools and renting of mining power are considered as sources of possible censorship threats and even 51% attacks for de- centralized cryptocurrencies. Non-outsourceable Proof-of-Work schemes have been proposed to tackle these issues. However, tenets in the folk- lore say that such schemes could potentially be bypassed by using es- crow mechanisms. In this work, we propose a concrete example of such a mechanism which is using collateralized smart contracts. Our approach allows miners to bypass non-outsourceable Proof-of-Work schemes if the underlying blockchain platform supports smart contracts in a sufficiently advanced language. In particular, the language should allow access to the PoW solution. At a high level, our approach requires the miner to lock collateral covering the reward amount and protected by a smart contract that acts as an escrow. The smart contract has logic that allows the pool to collect the collateral as soon as the miner collects any block reward. We propose two variants of the approach depending on when the collat- eral is bound to the block solution. Using this, we show how to bypass previously proposed non-outsourceable Proof-of-Work schemes (with the notable exception for strong non-outsourceable schemes) and show how to build mining pools for such schemes. 1 Introduction Security of Bitcoin and many other cryptocurrencies relies on so called Proof-of- Work (PoW) schemes (also known as scratch-off puzzles), which are mechanisms to reach fast consensus and guarantee immutability of the ledger. -

Coinbase Explores Crypto ETF (9/6) Coinbase Spoke to Asset Manager Blackrock About Creating a Crypto ETF, Business Insider Reports
Crypto Week in Review (9/1-9/7) Goldman Sachs CFO Denies Crypto Strategy Shift (9/6) GS CFO Marty Chavez addressed claims from an unsubstantiated report earlier this week that the firm may be delaying previous plans to open a crypto trading desk, calling the report “fake news”. Coinbase Explores Crypto ETF (9/6) Coinbase spoke to asset manager BlackRock about creating a crypto ETF, Business Insider reports. While the current status of the discussions is unclear, BlackRock is said to have “no interest in being a crypto fund issuer,” and SEC approval in the near term remains uncertain. Looking ahead, the Wednesday confirmation of Trump nominee Elad Roisman has the potential to tip the scales towards a more favorable cryptoasset approach. Twitter CEO Comments on Blockchain (9/5) Twitter CEO Jack Dorsey, speaking in a congressional hearing, indicated that blockchain technology could prove useful for “distributed trust and distributed enforcement.” The platform, given its struggles with how best to address fraud, harassment, and other misuse, could be a prime testing ground for decentralized identity solutions. Ripio Facilitates Peer-to-Peer Loans (9/5) Ripio began to facilitate blockchain powered peer-to-peer loans, available to wallet users in Argentina, Mexico, and Brazil. The loans, which utilize the Ripple Credit Network (RCN) token, are funded in RCN and dispensed to users in fiat through a network of local partners. Since all details of the loan and payments are recorded on the Ethereum blockchain, the solution could contribute to wider access to credit for the unbanked.

Liquidity Or Leakage Plumbing Problems with Cryptocurrencies
Liquidity Or Leakage Plumbing Problems With Cryptocurrencies March 2018 Liquidity Or Leakage - Plumbing Problems With Cryptocurrencies Liquidity Or Leakage Plumbing Problems With Cryptocurrencies Rodney Greene Quantitative Risk Professional Advisor to Z/Yen Group Bob McDowall Advisor to Cardano Foundation Distributed Futures 1/60 © Z/Yen Group, 2018 Liquidity Or Leakage - Plumbing Problems With Cryptocurrencies Foreword Liquidity is the probability that an asset can be converted into an expected amount of value within an expected amount of time. Any token claiming to be ‘money’ should be very liquid. Cryptocurrencies often exhibit high price volatility and wide spreads between their buy and sell prices into fiat currencies. In other markets, such high volatility and wide spreads might indicate low liquidity, i.e. it is difficult to turn an asset into cash. Normal price falls do not increase the number of sellers but should increase the number of buyers. A liquidity hole is where price falls do not bring out buyers, but rather generate even more sellers. If cryptocurrencies fail to provide easy liquidity, then they fail as mediums of exchange, one of the principal roles of money. However, there are a number of ways of assembling a cryptocurrency and a number of parameters, such as the timing of trades, the money supply algorithm, and the assembling of blocks, that might be done in better ways to improve liquidity. This research should help policy makers look critically at what’s needed to provide good liquidity with these exciting systems.
