Icon LinkTransaction ID

The transaction ID (also called transaction hash) of a transaction is computed as the hash of CHAIN_ID and the serialized transaction with fields zeroed out for signing (see different inputs and outputs for which fields are set to zero), and without witness data. In other words, only all non-witness data is hashed.

sha256(CHAIN_ID ++ serialized_tx(tx))
