Firstly, it employs cryptographic methods, including public-private key encryption algorithms, to ensure the security of the data. Each participant has their own public-private key pair, using the private key to sign the data, and other participants can verify the effectiveness of the signature via the public key. This ensures that only those with the correct private key can modify the data, thus securing its safety. Secondly, blockchain adopts distributed storage and consensus mechanisms to enhance security. Data is stored in a distributed manner within the blockchain network, rather than being centralized in one location. This means that even if a node is attacked or goes offline, other nodes can continue to validate and maintain  the integrity of the data."}]}],"pr":"a3c669d932408923e357884d340fef5abe77c92c8c41b82488fd23088dac4af8"}
