ChainCatcher news, according to The Block, the Cryptocurrency Innovation Council (CCI) plans to collaborate with one of its members, the Proof of Stake Alliance (POSA), to further explore staking issues. CCI stated that the market value of staking has increased from $19 million in 2019 to over $50 billion.U.S. lawmakers have been working on legislation regarding the taxation of staking, and the U.S. Securities and Exchange Commission has also brought charges against several companies' staking programs, including Kraken, Consensys, and Coinbase. The work of POSA will be led by Mangiero, who will collaborate with other members such as Ava Labs, Andreessen Horowitz, and Paradigm.Next year, POSA plans to release new policy documents and continue working with policymakers and regulators to clarify concepts such as re-staking.

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).
