Firstly, when smart contracts are deployed on the blockchain, they can ensure their tamper-proofness once they go online,  making the contract data trustworthy. Secondly, the distributed ledger technology of blockchain stores data on multiple nodes, enhancing the security of the data. Even if some nodes are attacked or fail, the overall network can still maintain stable operation. In addition, blockchain uses encryption algorithms (such as public keys and private keys) to encrypt and decrypt data, ensuring that only authorized users with the correct keys can access and process the data."}]}],"pr":"bb43f95b92a623bb1e46effc803434f2b77ec5093a335f8c32c4aa2d9a86dc34"}
