A blockchain is a type of distributed ledger that is useful for recording the transactions and balances of different participants. All transactions are stored in blocks, which are generated periodically and linked together with cryptographic methods https://sonia-primerano.com/. Once a block is added to the blockchain, data contained within it cannot be changed, unless all subsequent blocks are changed as well.

The miner that provides the correct solution to the problem first gets to add the new block of transactions to the blockchain and receives a reward in return for their work. Bitcoin miners are rewarded with BTC, Ethereum miners are rewarded with ETH, and so forth.

The term DeFi (decentralized finance) is used to refer to a wide variety of decentralized applications that enable financial services such as lending, borrowing and trading.

According to the UK 2020 national risk assessment—a comprehensive assessment of money laundering and terrorist financing risk in the UK—the risk of using cryptoassets such as bitcoin for money laundering and terrorism financing is assessed as “medium” (from “low” in the previous 2017 report). Legal scholars suggested that the money laundering opportunities may be more perceived than real. Blockchain analysis company Chainalysis concluded that illicit activities like cybercrime, money laundering and terrorism financing made up only 0.15% of all crypto transactions conducted in 2021, representing a total of $14 billion.

In 2021, 17 states in the US passed laws and resolutions concerning cryptocurrency regulation. This led the Securities and Exchange Commission to start considering what steps to take. On 8 July 2021, Senator Elizabeth Warren, part of the Senate Banking Committee, wrote to the chairman of the SEC and demanded answers on cryptocurrency regulation due to the increase in cryptocurrency exchange use and the danger this posed to consumers. On 5 August 2021, the chairman, Gary Gensler, responded to Warren’s letter and called for legislation focused on “crypto trading, lending and DeFi platforms,” because of how vulnerable investors could be when they traded on crypto trading platforms without a broker. He also argued that many tokens in the crypto market may be unregistered securities without required disclosures or market oversight. Additionally, Gensler did not hold back in his criticism of stablecoins. These tokens, which are pegged to the value of fiat currencies, may allow individuals to bypass important public policy goals related to traditional banking and financial systems, such as anti-money laundering, tax compliance, and sanctions.
