Specifically, whenever a transaction occurs, the transaction information is bundled into a transaction data package. This package will include information about the parties involved in the transaction, the transaction amount, the transaction items, etc. Next, the transaction data package will be propagated to all nodes in the entire blockchain network. After receiving the transaction data package, the nodes will verify it to ensure the validity of the transaction.\n\nDuring the transaction verification process, the nodes will use consensus mechanisms in blockchain technology to reach a consensus. There are different types of consensus mechanisms, such as Proof of Work (PoW) and Proof of Stake."}]}]}
