To prevent duplicates and ensure the lifecycle, transactions go through the following processes:\\n\\n1. Transaction Creation: The transaction is initiated by participants, containing information  such as the sender, receiver, and transaction amount.↵↵\\n\\n2. Signature Encryption: After the transaction is created, the sender encrypts the transaction information with a signature to ensure the authenticity and integrity of the transaction. The signature is used to prove that the flow of funds in the transaction is authorized by the owner of the funds.↵↵\\n\\n3. Broadcasting the Transaction: The encrypted transaction is sent to the Bitcoin network, and the neighboring nodes are the first to receive the broadcast. These nodes validate the transaction and propagate it further throughout the network."}]}],"pr":"8a87120696d5763c4ec4ac2f20788912bf19d14d914be7b8d5cceb9c8ff2dcdf"}
