Vitalik published an article explaining the PoS simplification proposal, suggesting a design that only requires 8192 signatures for each slot

Vitalik Buterin has published an article outlining a simplified PoS proposal, suggesting the design of a scheme that only requires 8192 signatures per slot (even when using SSF), aiming to make consensus implementation simpler and lighter. Vitalik proposed three methods: all included in decentralized staking pools; two-tier staking; rotating participation (like committees). Vitalik stated that he hopes to stick with 8192 signatures, which will make the work of technical implementers and builders of side infrastructure such as light clients easier. Anyone can run consensus clients more easily, and users, staking enthusiasts, and others will be able to immediately get rid of this assumption. The future load of Ethereum protocol is no longer an unknown: it can be increased through hard forks in the future, but only if developers are confident that technology has improved enough to handle more signature slots with the same efficiency. The remaining work is deciding which one or other method among these three should be adopted.
