What is a cryptocurrency transaction ID (TXID) or transaction hash?
A cryptocurrency transaction ID, also known as a transaction hash or TXID, is a unique identifier generated to recognize each transaction on the blockchain.
Every time a transaction occurs in a cryptocurrency network, whether it's Bitcoin, Ethereum, or another type of crypto, the details of the transaction such as the sender's address, the receiver's address, the amount sent, the time, and other relevant information are recorded and encrypted into a unique string of alphanumeric characters. This string, or hash, is the transaction ID.
You can think of a transaction ID as the equivalent of a bank transaction receipt. It allows users, as well as the broader network, to track and verify the status of transactions on the blockchain.
You can use this transaction ID on a blockchain explorer, a kind of search engine for blockchain transactions, to look up the transaction details and confirmations. This is an essential feature for troubleshooting transaction issues, ensuring transparency, and maintaining trust within the network.
