Decrypted TXID: The unique identification behind each transaction.

The Footprints Left by Transactions on-chain

In the world of blockchain, every transaction needs an ID - this is the transaction ID, also known as transaction identifier or transaction hash. Simply put, it is a unique sequence of characters, just like your identification number, used to uniquely identify a transaction across the entire blockchain network.

When you send cryptocurrency assets, the system automatically generates a TXID for the transaction. This ID is generated by applying a cryptographic hash function to the transaction details (including the sending address, receiving address, and transfer amount). Different blockchains use different hashing algorithms, but the principle is the same – ensuring that each transaction has a unique label.

Why You Need to Track Your Transactions

The most practical benefit of having a TXID is verifiability and troubleshooting. If your transfer has not arrived for a long time, or if you accidentally sent it to the wrong address, the TXID becomes your lifeline. Through the block explorer, you can enter this ID to view the complete information of the transaction — whether it was successful, the number of confirmations, transaction fees, and so on.

When withdrawing cryptocurrency from a centralized exchange platform, the withdrawal page will immediately display your TXID. If the funds were sent to the wrong blockchain or address, this ID can help you trace the whereabouts of the funds and provide evidence for subsequent requests for manual assistance.

Classic Case of Bitcoin

Bitcoin uses SHA-256 (256-bit Secure Hash Algorithm) to generate TXID, ultimately outputting a 64-character hexadecimal number. Two Bitcoin transactions are the most famous in history:

The first transaction was sent by Satoshi Nakamoto to Hal Finney: F4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16

Another transaction is the legendary “Pizza transaction”: Cca7507897abc89628f450e8b1e0c6fca4ec3f7b34cccf55f3f531c659ff4d79

You can copy these TXIDs to blockchain.com or blockchair.com and view the full details.

How to find your transaction ID

All transaction IDs can be publicly queried through block explorer, which means anyone can see the direction, amount, and timestamp of the transaction. While this provides complete transparency, the wallet address itself does not directly expose the real identity—though it can theoretically be traced through on-chain data analysis.

When withdrawing from a centralized exchange platform, the system will display the TXID in your withdrawal record. Click on this ID, and the platform will automatically redirect to the corresponding blockchain explorer page. If there is a problem with the transfer, this ID is essential information for contacting customer service – with it, the technical team can accurately locate the funds and assess whether recovery is possible.

Tips

Remember: Identifying and understanding your transaction ID is the foundation of safely using crypto assets. Before every large transfer, you should first confirm that the TXID indeed appears on the block explorer, so you can be at ease.
