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.
Bitcoin
Bitcoin (abbreviation: BTC or XBT; sign: ₿) is a decentralized digital currency. 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.
Cryptocurrency wallet
A cryptocurrency wallet is a device, physical medium, program or a service which stores the public and/or private keys for cryptocurrency transactions. In addition to this basic function of storing the keys, a cryptocurrency wallet more often offers the functionality of encrypting and/or signing information. Signing can for example result in executing a smart contract, a cryptocurrency transaction (see "bitcoin transaction" image), identification or legally signing a 'document' (see "application form" image).
Digital currency
Digital currency (digital money, electronic money or electronic currency) is any currency, money, or money-like asset that is primarily managed, stored or exchanged on digital computer systems, especially over the internet. Types of digital currencies include cryptocurrency, virtual currency and central bank digital currency. Digital currency may be recorded on a distributed database on the internet, a centralized electronic computer database owned by a company or bank, within or even on a stored-value card.
Blockchain
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). Since each block contains information about the previous block, they effectively form a chain (compare linked list data structure), with each additional block linking to the ones before it.
Tether (cryptocurrency)
Tether (often referred to by its currency codes, USD₮ and USDT, among others) is a cryptocurrency stablecoin, launched by the company Tether Limited Inc. in 2014. As of July 2022, Tether Limited has minted the USDT stablecoin on ten protocols and blockchains. Tether is described as a stablecoin because it was originally designed to be valued at US1 of asset reserves for each USD₮ 1 issued.
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, .
Blockchain analysis
Blockchain analysis is the process of inspecting, identifying, clustering, modeling and visually representing data on a cryptographic distributed-ledger known as a blockchain. The goal of blockchain analysis is to discover useful information about different actors transacting in cryptocurrency. Analysis of public blockchains such as Bitcoin and Ethereum is typically conducted by private companies like Chainalysis, TRM Labs, Elliptic, Nansen, CipherTrace, Elementus, Dune Analytics, CryptoQuant.
Decentralized finance
Decentralized finance (often stylized as DeFi) offers financial instruments without relying on intermediaries such as brokerages, exchanges, or banks by using smart contracts on a blockchain, mainly Ethereum. DeFi platforms allow people to lend or borrow funds from others, speculate on price movements on assets using derivatives, trade cryptocurrencies, insure against risks, and earn interest in savings-like accounts. DeFi uses a layered architecture and highly composable building blocks.
Chainalysis
Chainalysis is an American blockchain analysis firm headquartered in New York City. The company was co-founded by Michael Gronager, Jan Moller and Jonathan Levin in 2014, and is the first start-up company dedicated to the business of Bitcoin tracing. It offers compliance and investigation software to analyze the blockchain public ledger, which is primarily used to track virtual currencies. Its customers have included the United States Federal Bureau of Investigation, Drug Enforcement Administration, and the Internal Revenue Service Criminal Investigation, as well as the United Kingdom's National Crime Agency.
