ChainCatcher news, Vitalik published a long article on Warpcast titled "Possible futures of the Ethereum protocol, part 1: The Merge," in which he emphasized the exploration of "what improvements can be made to the technical design of proof of stake, and what are the pathways to achieve this goal?"Vitalik stated that the three goals of Ethereum staking are to maximize the number of validators that can participate in staking (which directly means minimizing the minimum ETH required for staking); to minimize the time for finality; and to minimize the overhead of running a node. Ideally, he hopes to maintain economic finality while improving the status quo in two areas: completing blocks within a time slot (ideally, maintaining or even reducing the current length of 12 seconds), rather than 15 minutes; and allowing validators to stake with 1 ETH (below the 32 ETH requirement).

ChainCatcher message, Ethereum co-founder Vitalik Buterin explained the limitations of ZK-VM (Zero-Knowledge Virtual Machine) in privacy use cases. Some users pointed out that ZK-VM is superior in almost every aspect, but ironically, the only use case it fails to cover is privacy.In response, Vitalik said: "The explanation is simple: privacy use cases require client-side proofs, and currently, client-side provers are not fast enough to handle anything beyond Merkle branches."
