Pre-processing: Before creating a new block, the miner needs to calculate the hash of the previous block and create a hash of the transaction data in the new block. ↵↵2. Generate candidate signature: The miner generates a candidate signature by combining the hash of the previous block, the hash of the transaction data in the new block, and the nonce (Number used once) used in the transaction.↵↵3. Solve the cryptographic puzzle: The miner needs to solve the cryptographic puzzle associated with the candidate signature. This puzzle is designed to be very difficult to solve, and the miner must consume a large amount of computing power to find the correct solution.↵↵4. Check the validity of the signature: The miner sends the candidate block to the blockchain network for verification. The network nodes will check the validity of the signature, ensuring that the miner has met","a":"Prepare data: First, the data to be signed, including the block header (Block Header) and block body (Block Body), needs to be prepared. The block  header contains information such as the hash value of the previous block, the difficulty target of the current block, and the timestamp. The block body contains multiple transaction records."}]}],"pr":"35e725fe6e7ed56661e2d5c9303153d6add282a7debfb651b34b5ef39a48d5ae"}
