These blocks are connected in the DAG structure via directed edges, representing the dependency relationships between transactions. Each block contains a set of transactions, which are arranged in a specific order within the block. In the DAG structure, nodes determine the dependency relationships between transactions by observing the edges between adjacent blocks. Typically, transactions in a block will refer to transactions in the previous block, forming a Directed Acyclic Graph structure. This structure helps to improve the throughput and processing  speed of the blockchain system while ensuring the integrity of the data."}]}],"pr":"0d6af73ac298d30c663b9b1bd4dbb2ff975fafd11fe37733b85f022277504750"}
