Firstly, the distributed storage mechanism involves distributing data and ledgers across different nodes in the blockchain network, without a centralized storage server, thereby enhancing the security of the data. Secondly, encryption technology uses public key cryptography to protect data and transactions. User wallets consist of public  keys and private keys, without which funds cannot be transferred, effectively preventing unauthorized use of funds. Additionally, consensus mechanisms (such as PoW or PoS algorithms) are used to validate transactions and reach data consensus, making it difficult for invalid transactions or data to be incorporated into the ledger, ensuring the integrity of the blockchain."}]}],"pr":"86a62629272e6265d9f77806a80e180232f8c86f33a6afc6dd03cb6e9b972531"}
