As the blockchain generates and updates data through a distributed node consensus algorithm, the validator set (also known as nodes) is responsible for verifying and recording new transactions. Once a transaction is added to the blockchain, it cannot be changed, ensuring the high  security and transparency of the blockchain. If the security of the nodes in the validator set is threatened, attackers may tamper with blockchain data or prevent transaction verification, thereby undermining the security and trustworthiness of the entire blockchain.\n\nTo improve the security of blockchain validation nodes, measures such as installing SSHGuard to protect SSH can be taken."}]}],"pr":"7c72be4193971accb6b5d6a02dc381e654437d83fc2757a2b48af8f55a918555"}
