A transaction ID (TXID), or transaction hash, is an immutable record of a digital transaction that's been recorded onto a blockchain ledger. Users are able to look up any past transactions using its corresponding transaction ID, typically with the help of a blockchain explorer. In some instances, a cryptocurrency recipient may request the transaction ID from the alleged sender in order to verify the transaction's origination point.
