Ethereum co-founder Vitalik Buterin proposed a "native DVT (Distributed Validator Technology)" concept on the Ethereum Research forum, suggesting that DVT be directly written into the Ethereum staking protocol layer to further promote validator decentralization while improving network security. According to this proposal, a single validator can register multiple independent keys, which together form a validator identity. Key operations such as block proposals and witnessing require a pre-defined threshold of keys to jointly sign before being considered valid, thus reducing the risk of a single point of failure or a compromised node causing a validator to go offline. Under reasonable threshold settings, the existing slashing mechanism can still function normally. Vitalik stated that this design allows validators to participate in staking without completely relying on a single node; as long as more than two-thirds of the nodes remain honest, the validator can continue to operate normally. Unlike current DVT schemes that rely on external coordination layers and complex deployments, this proposal advocates for native support of related mechanisms at the protocol layer. Validators meeting the minimum staking multiple requirement can configure up to 16 keys and set signature thresholds, essentially operating as a single validator with multiple standard nodes collaborating. In terms of performance, Vitalik believes the additional overhead of this scheme is limited, adding only one round of delay to block production, without causing additional delay to the witnessing process, and is compatible with different signature schemes, thereby reducing the risk of long-term reliance on a single cryptographic assumption. He also pointed out that native DVT is not only a tool for technical improvement but also helps improve decentralization metrics. By lowering the operational threshold of fault-tolerant staking, more individuals and institutions can choose to stake themselves rather than rely on large service providers, thereby increasing the diversity of validator distribution, including metrics such as the Nakamoto coefficient. Currently, this idea is still in the proposal stage and requires further extensive discussion and evaluation within the Ethereum community; it has not yet entered the specific implementation process.
