Please note that there should be no period at the end of the translation. Here is the translated content:
In his paper, Buterin introduced practical options explored by Ethereum to accelerate transaction confirmation speed, with a particular focus on single-slot finality (SSF) within existing technologies. Currently, Ethereum’s Gasper consensus mechanism utilizes a slot-and-epoch architecture, which is complex and has a long finality confirmation time (12.8 minutes). SSF, similar to the Tendermint consensus mechanism, terminates blocks before the next block is generated, while retaining the “inactive leakage” mechanism to ensure the stable operation and recovery capability of the chain when more than one-third of validators go offline. The main challenge of SSF is the significant load it imposes on the chain, but new proposals like Orbit SSF are dedicated to mitigating this issue. Additionally, the paper explores rollup pre-confirmation and pre-confirmation-based mechanisms.
