# 6.2 The Inter-Chain Handshake Mechanism

When an asset moves across chains, the protocol requires an Inter-Chain Handshake. This is a two-step cryptographic process:

1. Departure Proof: The origin chain emits a "Lineage Export" event, freezing the local registry state for that asset.
2. Arrival Validation: The destination chain’s Provenance module verifies the Export Proof before minting a "Lineage-Verified Wrapped Asset."\
   This ensures that the "Chain of Custody" is never broken, even when crossing the vast expanse of the multi-chain ecosystem. In the Provenance Network, truth is a fluid, global commodity that flows across bridges with the same cryptographic rigor as a native Ethereum transaction.
