Firstly, the decentralized feature allows data in the blockchain network to not be dependent on a single central node, thereby improving data security. Secondly, the immutable data in blockchain means that once data is recorded in a block, it cannot be modified or deleted, providing a reliable basis for the execution of smart contracts. Additionally, blockchain adopts encryption algorithms (such as SHA-256) to ensure data security, allowing only users with the correct keys to access  and process the data. Lastly, smart contracts can be trusted to perform as intended due to the tamper-proof nature of the blockchain technology."}]}],"pr":"7576e1566bde2aa4c40f4957e44555579f5b196e057243b41f54c4e96465d2b6"}
