The DAG structure does not have the concept of blocks, but connects data units in a semi-ordered relationship. The characteristic of this technology is to asynchronize the write operation of data units, allowing a large number of wallet clients to autonomously asynchronously write transaction data into the  DAG, thus supporting high concurrency and fast processing. Combining double-layer consensus mechanisms and using proof-of-work consensus algorithm, DAG technology can prevent the double-spending problem. This technology is considered an innovation in the era of Blockchain 3.0, as it significantly transforms the blockchain and solves the problems of traditional blockchain structures."}]}],"pr":"fde501df3c16a2b821e5d7f455ba59d060fc27b486bdc28c1f9c2551f68cd4f5"}
