The digest for a transaction (its transaction ID, or tid) is computed once upon constructed when the STTx is deserialized. Subsequent calls to retrieve the digest use the cached value. Any code which modifies the STTx and then attempts to retrieve the digest will terminate the process with a logic error contract violation. * Nested types removed * All STTx are contained as const (Except in transaction sign, which must modify) * tid in STTx is computed once on deserialization
