Wormhole VAA technology
Overview
Wormhole VAA (Verifiable Action Approval) is a cryptographic message format used by the Wormhole cross-chain bridge protocol to attest and authorize cross-chain transactions. It is emitted by a guardian network after observing an event on a source blockchain, and contains the signed approval needed to execute the corresponding action on a destination chain. VAAs serve as the core trust mechanism enabling secure interoperability between disparate blockchains.
