Firstly, blockchain adopts a decentralized architecture, distributing data storage  and verification across multiple nodes in the network, without relying on a single central authority, thus improving data security and stability. Secondly, blockchain technology utilizes encryption algorithms (such as SHA-256) to protect the privacy and security of data. Each participant has a private key and a public key, with the private key used for signing transaction records and the public key used for verifying signatures. This encryption technology can effectively prevent fraud and tampering. In addition, blockchain also adopts high redundancy, meaning that a certain number of nodes in the network must confirm a transaction before it is considered valid, further enhancing data security.↵↵Blockchain technology ensures data security through various means such as decentralized architecture, encryption algorithms, and permission management.
