Initialize the validation process: The first step is to initialize the validation process, which involves loading the latest blockchain data into the validator's system. This data includes the current block height, the list of active nodes, and the transaction records in the latest blocks.\n\n2. Verify the block header: The validator checks the block header of the current block, including the timestamp, previous block hash, merkle root hash, and difficulty target. The validator uses these values to determine if the block is valid according to the blockchain's consensus algorithm.\n\n3. Verify the transactions: The validator reviews the transactions included in the current block. This involves checking the transaction inputs and outputs, ensuring that they are valid and compliant with the blockchain's rules. The validator also verifies the digital signatures associated with the transactions to ensure their authenticity.","a":"Validate the hash value of the previous block: The blockchain is composed of multiple blocks linked in chronological order, with each block containing the hash value of the previous block. In the validate invariant  process, the first step is to verify whether the hash value of the current block matches the hash value of the previous block, ensuring the sequence and connection between blocks are correct."}]}],"pr":"13bd2dddd6030cfdcf4aaedd84440c94eba668a93945c0c98aceeb72c6e02597"}
