The bridge

The bridge is a lightweight, distributed cross-chain notary. Read the the protocol spec first.

  • Leaderless. There is no synchrony/consensus or proposers - the bridge merely observes finalized transactions on one chain, signs them using its piece of the joint key, and pushes its signature to an off-chain peer-to-peer network. Once 2/3+ of the guardian set agree, the threshold signature is valid and this jointly signed proof (which we call a Verifiable Action Approval or VAA) can be posted to the other chain to release or mint funds that were locked/burned on the first.

  • Stateless. Nodes do not keep persistent state about transactions they observed.
