Tornado Cash is a decentralised, non-custodial privacy solution built on the Ethereum blockchain, introduced to enhance transaction anonymity. It uses advanced cryptographic techniques such as zero-knowledge proofs to obfuscate the link between sender and receiver addresses. This allows users to send and receive Ether and other ERC-20 tokens without divulging their identities, fostering an environment of secure and private transactions. Tornado Cash was created to address the inherent transparency of blockchain transactions, providing users with the ability to transact without leaving a traceable history. By focusing on privacy, Tornado Cash aims to bolster privacy rights in the digital landscape, offering users greater control over their financial activities.
