First, decentralization means that there is no single central node, and transaction information spreads throughout the network, reducing the risk of tampering and attack. Secondly, blockchain adopts encryption algorithms (such as SHA-256) to encrypt transaction information, ensuring the security of the data. In addition, consensus mechanisms in blockchain  (such as proof of work, proof of stake, etc.) ensure trust between network participants, avoiding security risks such as double-spending attacks.↵↵At the same time, blockchain technology can also achieve accuracy in value transfer, security in data storage, and transaction information."}]}],"pr":"a4eff979823dfe00de68bf3583d01468af069c3dbe99feef62bdcda656242f9e"}
