This process includes several stages: transaction creation, signature encryption, broadcasting, validation, and new block generation.↵↵Firstly, the transaction creation stage refers to the process where a user initiates a transaction, specifying the Bitcoin addresses and amounts of both parties involved. Next, in the signature encryption stage, the transaction information is signed to ensure its validity and security. Following that, the transaction is broadcasted to the Bitcoin network, and adjacent nodes receive the broadcast and validate it before re-broadcasting it to the network. This process continues until most nodes have received the information.↵↵In the validation stage, nodes perform a series of checks on the transaction, including verifying the digital signature, ensuring the transaction meets the network's consensus rules, and checking for duplicate  transactions. If the transaction passes these checks, it is considered valid and"}]}],"pr":"c4c8e63ed974ba37fdf1a7e16db4f79758c1e16c0df575b90a265aeda9661696"}
