Tornado Cash is a decentralized mixer that uses smart contracts to break the link between deposited and withdrawn funds. Users deposit tokens into a pool and later withdraw them to a new address, generating a cryptographic proof (zk-SNARK) to verify their eligibility without revealing the original deposit. This process obscures transaction histories, but regulators have targeted it for enabling money laundering, leading to its blacklisting in some jurisdictions.
