Transaction ID (TXID)

    A Transaction ID (TXID) is an identification number assigned to every verified transaction on a blockchain. On blockchains that support TXIDs (or equivalent), every transaction that has ever occurred on the blockchain will have a TXID assigned. The TXID is generated by the blockchain and assigned when new transactions are added to the chain. The TXID verifies that the transaction took place and facilitates the user’s ability to directly reference the transaction as needed (i.e., in a communication). Tools such as block explorers use the TXID. In a block explorer, the user can search for a transaction using the transaction ID. Block explorers provide basic transaction information such as: amount sent; date of transfer; sending and receiving addresses; and the number of network confirmations the transaction has received.
