Ethereum’s Gasper consensus protocol typically requires 64 to 95 slots-the units of time during which a new chain extending the previous one by one block is proposed and voted-to finalize, even under ideal conditions with synchrony and honest validators. This exposes a significant portion of the blockchain to potential reorganizations during changes in network conditions, such as periods of asynchrony.

In this talk, I will introduce 3SF, a novel consensus protocol that addresses these limitations. With 3SF, finality is achieved within just three slots after a proposal, drastically reducing the exposure to reorganizations. This presentation will explore the motivation, design, and implications of 3SF, offering a new perspective on the future of Ethereum’s consensus protocol.
