In the DAG structure, transactions are regarded as nodes in the graph, and edges represent the verification relationship between transactions. This structure allows for more complex interactions and relationships within the blockchain."}]}],"pr":"a4eb16a230b048c158815254d45ca669f689cf7b9453ffd4041c0ba17189dfcd"}
