Tx Hash means Transaction Hash and is also known as Transaction ID (TxID). It consist of alphanumeric characters and is basically an identification number given for a Bitcoin transaction. Each and every single transaction that is conducted on the Bitcoin blockchain has this unique identifier. Similarly transactions on Ethereum blockchain will have a unique Tx hash and every transaction on Litecoin blockchain will also have a TxID.
For example a Bitcoin transaction ID looks like this:
A transaction hash of Ethereum looks like this:
This unique identifier is a long string of letters and numbers that is used to identify a specific transaction on the blockchain.
Use of TxHash and TxID
All transactions on blockchain are publicly available. Once you make a payment or transfer coins to another address the transaction gets broadcasted and a Tx Hash ID will also get generated. Using the transaction ID one can easily track and trace the status of a transaction. They will get to know the whole details of the transfer such as: sender address, receiver address, total amount send, the date of transfer, block height, fees paid and the number of confirmations.
Transaction Hash and IDs contain no personal information so it is completely safe to share. But how are these transaction hash and IDs useful? As we said it is useful in many ways: For example you can share this information to the service provider to let them know the status of the transfer. You can share your transaction ID to the merchant to confirm the transaction is successful and there are many other scenarios in which you may require this.
