Firstly, decentralization means that there is no central  node, and data is stored on multiple nodes, ensuring that no single entity can control the data, increasing transparency and creating an environment without trust. Secondly, blockchain adopts advanced cryptographic technologies, such as end-to-end encryption and public key infrastructure, to protect users' sensitive information. In addition, hash functions enable the network to maintain data integrity. Smart contracts run automatically on the blockchain network to handle and validate transactions. These technologies together ensure data privacy, security, and integrity."}]}],"pr":"c3bd4d461cb88f53ab1018f3be006f4a37e172befe588e7de7378a9f962e0f03"}
