What Is TXID? TXID, short for “transaction ID” and also known as TXID, is a hash number that records a transaction on the blockchain. Let's explore more.
What Is TXID?
Blocks that make up a blockchain are composed of numerous transactions. A TXID is required if a user wants to know when a cryptocurrency transaction was made on the blockchain.
Blockchain transactions are immutable, preventing censorship and establishing a system without trust. TXIDs are thus clear evidence that money was spent. The data is permanently recorded on the blockchain and cannot be removed. A public TXID can assist in recovering cash if a crypto exchange need proof of a lost deposit or withdrawal.
TXIDs are absent from several cryptos. These are private, anonymous cryptos like Monero and ZCash that don't keep track of transactions and hide payment information and balances. On Bitcoin and Ethereum, users can easily see all transactions that occurred publicly through block explorers. Block explorers show all transactions on the blockchain in real-time and allow users to view crypto balances. The most used explorer for Bitcoin is Blockchain.com, and for Ethereum it's Etherscan.
The 64-character TXIDs on both Bitcoin and Ethereum can contain any random combination of letters and digits. Despite sharing a similar encoding style with wallet addresses, the TXID is just a record of a specific transaction that happened on the blockchain.
How Do TXIDs Benefit Blockchains?
TXIDs include important data about all transactions that took place throughout the chain's history in addition to showing that money was actually spent on the blockchain. The accuracy of the data being transmitted for upcoming block creation and mining may be checked using these 64-character hashes.
A blockchain's main goal is to build a trustworthy, unchangeable ledger for payments. It cannot be changed or undone, hence it is immutable. If a user double-encrypts a transaction, they get a certain hash/TXID that is immutable as long as the blockchain continues. This guarantees censorship resistance and removes the trust aspect, allowing people to spend their money without worrying about it being stolen or frozen like it could in a bank. It also means that TXID's/hashes will be searchable on block one of the blockers listed above even 10 years later.
