Expand description

CertificateProof is a proof that a transaction certs existed at a given epoch and hence can be executed. There are two types of proofs: one that is proven by inclusion in a checkpoint and one that is proven by quorum signature.

Variants§

§

Checkpoint(EpochId, CheckpointSequenceNumber)

Validity was proven by inclusion in the given checkpoint

§

Certified(AuthorityStrongQuorumSignInfo)

Validity was proven by transaction certificate signature

§

QuorumExecuted(EpochId)

At least f+1 validators have executed this transaction. In practice, we will always get 2f+1 (effects cert), but theoretically f+1 is enough to prove that the transaction is valid.

§

SystemTransaction(EpochId)

Transaction generated by the system, for example Clock update transaction
