Tornado.Cash employs Zero-Knowledge Succinct Non-Interactive Argument of data (also referred to as zk-SNARK) to validate & let transactions.To method a deposit, Tornado.Cash generates a random place of bytes, computes it throughout the Pedersen Hash (as it can be friendlier with zk-SNARKs), then sends the token & the 20 MiMC hash to your wise agreement.

The nullifier is hashed. This nullifier is a public input that is sent on-chain being checked with the wise deal & the Merkle tree data. It avoids double-paying out for instance.
