Firstly, blockchain adopts a decentralized architecture, distributing data storage and validation across multiple nodes in the network, ensuring data security and transparency. Secondly, encryption algorithms such as the SHA-256 algorithm used in Bitcoin are applied in data transmission and transaction processes to encrypt and protect transaction information. Additionally, nodes in the blockchain network need to solve complex mathematical problems (such as proof of work) to obtain accounting rights, thereby ensuring data security and consistency.\n\nDuring the validation process, the blockchain system will automatically"}]}],"pr":"f0df77e43a2ad0b44b5c577d2b219997f7a07a9ae7a34071d64af9b13b1a0c06"}
