Vitalik proposes to introduce a native DVT staking mechanism at the Ethereum protocol layer to enhance security and decentralization BlockBeats News: On January 21st, Ethereum co-founder Vitalik Buterin recently proposed a "native DVT (distributed validator technology)" solution at the Ethereum Research Forum, suggesting that DVT be directly written into the Ethereum staking protocol layer to enhance network security and promote decentralization at the validator level. According to the proposal, validators can register multiple independent keys and operate together in the form of 'group validators'; The block proposal or witness will only be considered valid after reaching the set threshold number of key signatures. This mechanism can significantly reduce the risk of validators going offline due to single point of failure or node breach, while still maintaining existing slash protection under reasonable threshold settings. Vitalik pointed out that unlike current DVT solutions that rely on external coordination layers and deploy complex DVT, native DVT will be directly embedded into the protocol itself. A validator holding multiple times the minimum staking threshold (32 ETH) can set up to 16 keys and specify a signature threshold, equivalent to multiple standard nodes forming a validator identity together. He stated that the design has extremely low additional overhead in terms of performance, only adding one extra delay for block generation without affecting witness delay, and is compatible with any signature scheme, which helps reduce reliance on encryption assumptions that may pose long-term risks. At the level of decentralization, Vitalik believes that native DVT can make it easier for individuals and institutions to directly participate in staking in a "self hosted, fault-tolerant" manner, rather than relying on large staking service providers, thereby improving the decentralization metrics of the Ethereum validator set (such as the Nakamoto coefficient). The proposal is still in the early stages of discussion and will require extensive evaluation and consensus from the Ethereum community in the future.
