  A blockchain node ensures the security of digital currency transactions through a combination of cryptographic algorithms and consensus mechanisms. Each transaction is verified by multiple nodes in the network, and once consensus is reached, it is added to the blockchain. This decentralized nature of the blockchain makes it extremely difficult for any single entity to manipulate or tamper with the transaction history. Additionally, the use of cryptographic signatures ensures that only the rightful owner of the digital currency can initiate a transaction, preventing unauthorized access and fraud.

  Blockchain nodes ensure the security of digital currency transactions by maintaining a copy of the entire blockchain and participating in the consensus process. They validate transactions by checking the digital signatures and ensuring that the transaction follows the predefined rules and protocols. By continuously verifying and validating transactions, nodes help maintain the integrity of the blockchain and prevent double-spending or other fraudulent activities. In case of any discrepancies or attempts to tamper with the transaction history, the consensus mechanism ensures that the majority of nodes agree on the correct version of the blockchain, effectively rejecting any malicious changes.
