First, the decentralized feature means that there is no single central node that controls  the data, thereby reducing the risk of single-point failure and improving the system's stability. Second, blockchain adopts encryption technology to encrypt and validate data, ensuring the security of the data. On this basis, consensus algorithms (such as proof of work, proof of stake, etc.) are used to confirm and validate transactions, ensuring the consistency of data in the blockchain network.↵↵In addition, blockchain technology also has the advantage of lower storage costs. Because blockchain adopts distributed storage, data is distributed across multiple nodes."}]}],"pr":"3a48116ee4cb53e03ad30f09d2ec950fcb0888bd635f50af634c875640190fd2"}
