In DAG blockchain technology, each user can submit a data unit, which can contain various information, such as transactions, messages, etc. The data units  are linked together through reference relationships, forming a DAG structure with a semi-ordered relationship. The characteristic of this structure is to asynchronize the write operation of data units, allowing a large number of wallet clients to autonomously asynchronously write transaction data into DAG, thus supporting high concurrency and fast processing. Meanwhile, DAG blockchain technology can also combine dual-layer consensus mechanisms and utilization."}]}],"pr":"b12a27799ad1ff98a92440828759dc35539b52ec08381363e8e8823bf0d80a76"}
