Interface ConsensualSignedTransaction

  • All Implemented Interfaces:
    net.corda.v5.ledger.common.transaction.TransactionWithMetadata 
    @DoNotImplement() 
public interface ConsensualSignedTransaction
 implements TransactionWithMetadata

    Defines a consensual signed transaction.

    Comparing with ConsensualLedgerTransaction:

    • It does not have access to the deserialized details.
    • It has direct access to the signatures.
    • It does not require a serializer.

    ConsensualSignedTransaction wraps the wire representation of the transaction, which contains one or more signatures, each one for a public key (including composite keys) that is mentioned inside a transaction state.

    ConsensualSignedTransaction is frequently passed around the network and stored. The identity of a transaction is the hash of Merkle root of the wrapped wire representation. Therefore, if you are storing data keyed by wire representations hash, be aware that multiple different ConsensualSignedTransactions may map to the same key (and they could be different in important ways, like validity).

    The signatures on a ConsensualSignedTransaction might be invalid or missing: the type does not imply validity.

    A transaction ID should be the hash of the wrapped wire representation's Merkle tree root.

    Adding or removing a signature does not change the transaction ID.
