Traditional blockchain systems, such as Bitcoin and Ethereum, have relatively low transaction efficiency due to their use of a chain-based structure and the Proof of Work (PoW) consensus mechanism. The block generation speed of  Bitcoin is approximately 10 minutes per block, and the transaction throughput is around 7 transactions per second. Ethereum adopts the Proof of Stake (PoS) consensus mechanism, which improves transaction throughput but is still limited.↵↵To enhance the transaction efficiency of blockchains, researchers and developers have proposed many solutions, one of which is the Directed Acyclic Graph (DAG) structure."}]}],"pr":"9dc80cd800ad07ee5c412c0686219057bf7feaa399210388eecd758e343e1162"}
