What is a Bitcoin transaction ID?

A Bitcoin transaction ID is a unique identifier assigned to each transaction on the Bitcoin blockchain. It is also known as a transaction hash or a transaction ID (TXID). It is a string of alphanumeric characters which is used to identify a particular Bitcoin transaction on the blockchain.

A transaction ID is an alphanumeric string of characters which is unique to each individual transaction. It is generated when a transaction is broadcasted to the network and is used to refer to the transaction. It can be found in a Bitcoin wallet that contains the transaction and can be shared with others to prove a transaction has taken place.

A Bitcoin transaction ID can also be used to track a transaction on the blockchain, allowing users to view the details of a transaction, including the sender, recipient, date and amount.
