The power of Tornado Cash lies in its use of advanced cryptography called zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge). This technology enables the network to verify the validity of a transaction without revealing any sensitive information about it, such as the sender, receiver, or amount. This ensures that your financial activities remain confidential. The Tornado Cash site offers a deeper dive into how this complex technology works to protect your on-chain data from prying eyes and chain analysis.
