Vitalik proposed three methods to simplify the Ethereum POS mechanism

ChainCatcher news, Ethereum co-founder Vitalik Buterin published an article proposing three methods to simplify Ethereum's proof-of-stake design.

The first solution focuses on decentralized staking pools. This would expand the minimum deposit required to run a validating node to 4096 ETH and facilitate the reorganization of validating node resources.

The second method is two-tiered staking, where the heavy layer requires a stake of 4096 ETH and participates in finality, while the light layer has no minimum stake requirement (nor deposit and withdrawal delays). These two layers will be treated differently in the block finalization process.

The third method is alternating participation (i.e., committees with accountability), which means selecting a random set of validators for each slot. This would distribute the workload and reduce the total number of signatures, but this approach increases protocol complexity. The advantage is that it retains individual staking in a recognizable form, maintains a first-level system, and even allows the minimum deposit size to be lowered to very low levels (e.g., 1 ETH).
