Most bridges operate as transparent relays, when you bridge 100 ETH from Ethereum to Solana, observers can easily link your source address to your destination address by analyzing deposit and withdrawal timestamps, amounts, and token types. 1/12

The gateway then verifies the coordinator's signature, checks the nullifier hasn't been used, marks it as spent, and releases tokens from its vault to the recipient address. 12/12

The note gets inserted inZcash's global commitment tree, a Merkle tree with crypto commitments to every shielded note in existence. The user now possess a Zcash note representing their bridged assets, this note's existence is completely disconnected from the initial deposit 11/12

Unlike most bridges that merely facilitate token movement while exposing complete transaction graphs, ZeroBridge leverages Zcash's Orchard shielded pool as a privacy intermediary, severing the on-chain connection between deposits and withdrawals through zero-knowledge proofs.
