  The transaction hash plays a crucial role in ensuring the security of digital currency transactions. It acts as a digital signature that verifies the authenticity and integrity of the transaction. When a transaction is created, it is assigned a unique hash value based on its content. This hash value is then included in the transaction data and stored on the blockchain. Whenever someone wants to verify the transaction, they can calculate the hash of the transaction data and compare it with the stored hash. If the two hashes match, it means that the transaction has not been tampered with and is therefore secure. This prevents any unauthorized changes to the transaction data and ensures the security of digital currency transactions.
