What is transaction ID (Hash):

It is like a fingerprint of data, and the form of expression can be expressed by a string of letters, numbers or other symbols. It can also be understood as: the transaction hash on the blockchain is the transaction number. For example, if we transfer 10 tokens from address A to address B, we will use the address A for private key signature to get a SIGN (signature). Then this signature is combined with the transaction, and finally the hash value operation is performed to get TxHash (hash value). And then broadcast to the network, if the transaction is successful (focus), you can query the transaction number on the blockchain network, which is TxHash. If it is a failed transaction, the data will not be uploaded to the chain and the hash value will naturally be invalid.
