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":"Calculate  the hash value: Based on the prepared data, including the random number, the hash value of the block is calculated.
