 At its core, Wormhole is secured by a network of [Guardian](#){target=\_blank} nodes that validate and sign messages. If a super majority (e.g., 13 out of 19) of Guardians sign the same message, it can be considered valid. A smart contract on the target chain will verify the signatures and format of the message before approving any transaction.

 - Guardians produce signed state attestations (signed VAAs) when requested by a Core Contract integrator
 - Every Guardian runs full nodes (rather than light nodes) of every blockchain in the Wormhole network, so if a blockchain suffers a consensus attack or hard fork, the blockchain will disconnect from the network rather than potentially produce invalid signed VAAs
 - Any Signed VAA can be verified as authentic by the Core Contract of any other chain
