Tornado Cash
Tornado Cash is a decentralized, non-custodial privacy solution built on the Ethereum blockchain that enables users to enhance their transaction anonymity. It employs zero-knowledge proofs, specifically zk-SNARKs, to allow users to send Ethereum and ERC-20 tokens with increased confidentiality by breaking the on-chain link between the sender and receiver addresses. This project has gained significant attention, especially as privacy in cryptocurrency transactions has become a prominent topic, but it also faces scrutiny and regulatory challenges due to concerns about potential illicit activities.
