Each block contains a certain number of transaction records, timestamps, and a hash value pointing to the previous block. When a new block is  created, its hash value is calculated based on the hash value of the previous block, the new transaction block, and a random number. This connection method forms an unchangeable chain structure between blocks, ensuring the security and consistency of blockchain data. Meanwhile, miners can only begin calculating eligible random numbers based on the data of the previous block, which ensures the mining process."}]}],"pr":"377f639f0a22ea390a48862e0f4bf53ee84223c1ad34b4dc44a150355771f443"}
