How it works

Cross Chain Messaging Protocol consists of 3 steps:

1. Emit event on the SRC chain

2. Verify the event and get proof from the Signer

3. Receive the event on the DEST chain

The key part of the protocol is proof of the event.

Signer Service is responsible for producing proofs, whereas Signers Registry smart contract is responsible for validation if proof was made by the correct Signer.
