Its main features include decentralization, immutability, and anonymity. The decentralized characteristic means that no central institution can control data storage and transactions, thereby reducing the risk of single-point failure. The immutable characteristic ensures the integrity and authenticity of the data, as each block contains the hash value of the previous block. Once the data in a block is altered, it will cause a chain reaction in subsequent blocks, making it almost impossible for the entire blockchain's data to change. The anonymous characteristic ensures the privacy of transaction participants."}]}],"pr":"34dded9cd7d6268be6f3f919e350e656e21cf126992b86a02d7652a79f3d6734"}
