These nodes store the transaction information in a memory pool, waiting for miners to package. Then, miners pick up the transactions from the memory pool, attempting to solve a random puzzle related to the transaction (proof of work). After solving the puzzle, the miner packages  the transaction information into a new block and broadcasts the block to the entire Bitcoin network. Other nodes receive the new block and verify it to confirm the validity of the transaction. Once the verification is passed, the transaction is considered complete."}]}],"pr":"5c5bb896b1c56aa3c42497b07c514317d9eee62824b721b2c70b7c1626292819"}
