If the received block is found to be valid and its predecessor is in the longest chain, the node will append the received block to the longest chain and start the process of validating the next block. This process ensures that the blockchain maintains a consistent and tamper-proof ledger of transactions."}]}],"pr":"9a1decae893118147d6428bd0890ac4a6cb49b2a7fe73fdff9ba402887027b48"}
