[Vitalik discusses how Ethereum can speed up transaction confirmation time] Ethereum co-founder Vitalik Buterin recently published an article to explore in depth how to provide Ethereum users with faster transaction confirmation time. He pointed out that although Ethereum's transaction confirmation time has been shortened to 5-20 seconds, further reducing delays is still of great value. In the article, Vitalik introduced practical options that Ethereum is exploring, including single-slot finality (SSF). SSF uses a mechanism similar to Tendermint to terminate blocks before the next block is generated, ensuring the stable operation and recovery of the chain. Although SSF will bring a large load to the chain, new proposals such as Orbit SSF are working to solve this problem. Vitalik emphasized that the design space needs to be explored more comprehensively to reduce transaction confirmation time and improve user experience.
