Specifically, data records in a blockchain system are organized in blocks, each  containing a certain number of transaction records. When a new block is added to the blockchain, it contains the hash value of the previous block, forming a chain-like structure. This chain structure gives blockchain the characteristic of being difficult to tamper with.↵↵In addition, blockchain employs encryption algorithms (such as SHA-256) to ensure the security of the data. Each block header contains a temporary random number (non-ceremonial random number), which is used together with the hash value of the previous block to create a unique identifier for the block. This unique identifier makes it difficult for anyone to tamper with the block without being detected."}]}],"pr":"73d367306c8c4169627a4a28db0db73f9638765a243b153901095ee2b07e3a9a"}
