Cryptocurrency Tumbler
A cryptocurrency tumbler or cryptocurrency mixing service is a service that mixes potentially identifiable or "tainted" cryptocurrency funds with others, so as to obscure the trail back to the fund's original source. This is usually done by pooling together source funds from multiple inputs for a large and random period of time, and then spitting them back out to destination addresses. As all the funds are lumped together and then distributed at random times, it is very difficult to trace exact coins. Tumblers have arisen to improve the anonymity of cryptocurrencies, usually bitcoin (hence bitcoin mixer), since the currencies provide a public ledger of all transactions. Due to its goal of anonymity, tumblers have been used to money launder cryptocurrency. Background Tumblers take a percentage transaction fee of the total coins mixed to turn a profit, typically 1–3%. Mixing helps protect privacy and can also be used for money laundering by mixing illegally obtained funds. Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptocurrency
A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. It is a decentralized system for verifying that the parties to a transaction have the money they claim to have, eliminating the need for traditional intermediaries, such as banks, when funds are being transferred between two entities. Individual coin ownership records are stored in a digital ledger, which is a computerized database using strong cryptography to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. Despite their name, cryptocurrencies are not considered to be currencies in the traditional sense, and while varying treatments have been applied to them, including classification as commodities, securities, and currencies, cryptocurrencies are generally viewed as a distinc ...

Privacy And Blockchain
A blockchain is a shared database that records transactions between two parties in an immutable ledger. Blockchain documents and confirms pseudonymous ownership of all transactions in a verifiable and sustainable way. After a transaction is validated and cryptographically verified by other participants or nodes in the network, it is made into a "block" on the blockchain. A block contains information about the time the transaction occurred, previous transactions, and details about the transaction. Once recorded as a block, transactions are ordered chronologically and cannot be altered. This technology rose to popularity after the creation of Bitcoin, the first application of blockchain technology, which has since catalyzed other cryptocurrencies and applications. Due to its nature of decentralization, transactions and data are not verified and owned by one single entity as they are in typical systems. Rather, the validity of transactions are confirmed by the form of majority-rule in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptocurrency And Crime
Cryptocurrency and crime describes notable examples of cybercrime related to theft (or the otherwise illegal acquisition) of cryptocurrencies and some of the methods or security vulnerabilities commonly exploited. Cryptojacking is a form of cybercrime specific to cryptocurrencies that has been used on websites to hijack a victim's resources and use them for hashing and mining cryptocurrencies. According to blockchain analysis company Chainalysis, 15% of cryptocurrency transactions conducted in 2021 were involved in illicit activities like cybercrime, money laundering and terrorism financing, representing a total of $14 billion. Background There are various types of cryptocurrency wallets available, with different layers of security, including devices, software for different operating systems or browsers, and offline wallets. Novel exploits unique to blockchain transactions exist which aim to create unintended outcomes for those on the other end of a transaction. One of the m ...

Anonymity
Anonymity describes situations where the acting person's identity is unknown. Some writers have argued that namelessness, though technically correct, does not capture what is more centrally at stake in contexts of anonymity. The important idea here is that a person be non-identifiable, unreachable, or untrackable. Anonymity is seen as a technique, or a way of realizing, a certain other values, such as privacy, or liberty. Over the past few years, anonymity tools used on the dark web by criminals and malicious users have drastically altered the ability of law enforcement to use conventional surveillance techniques. An important example for anonymity being not only protected, but enforced by law is the vote in free elections. In many other situations (like conversation between strangers, buying some product or service in a shop), anonymity is traditionally accepted as natural. There are also various situations in which a person might choose to withhold their identity. Acts of cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sheep Marketplace
Sheep Marketplace was an anonymous marketplace set up as a Tor hidden service. It launched in March 2013 and was one of the lesser known sites to gain popularity with the well publicized closure of the Silk Road marketplace later that year. It ceased operation in December 2013, when it announced it was shutting down after a vendor stole $6 million worth of users' bitcoins. Bitcoin theft incident In December 2013 Sheep Marketplace announced that one of the site's vendors exploited a vulnerability to steal 5,400 bitcoins, valued at about $6 million at the time. According to ''Forbes'' and ''The Guardian,'' several users reported the site had started to block withdrawals of bitcoins more than a week prior to the theft. Users furthermore suggested the site's administrators held far more than 5,400 bitcoins, pointing to records of a coincidental transfer of almost 40,000. As users in the site's forums began to complain and discuss the possibility of connivance, administrators took th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitcoin
Bitcoin ( abbreviation: BTC; sign: ₿) is a decentralized digital currency that can be transferred on the peer-to-peer bitcoin network. Bitcoin transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. The currency began use in 2009, when its implementation was released as open-source software. The word "''bitcoin''" was defined in a white paper published on October 31, 2008. It is a compound of the words ''bit'' and ''coin''. The legality of bitcoin varies by region. Nine countries have fully banned bitcoin use, while a further fifteen have implicitly banned it. A few governments have used bitcoin in some capacity. El Salvador has adopted Bitcoin as legal tender, although use by merchants remains low. Ukraine has accepted cryptocurrency donations to fund the resistance to the 2022 Russ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
