Ethereum co-founder Vitalik Buterin in a post on Ethereum Research that he is proposing “native” distributed validator technology by enshrining DVT into the Ethereum protocol, aiming to help stakers reduce dependence on a single node.
Buterin described DVT as splitting a validator key across multiple nodes and using threshold signing so the setup can keep operating as long as a supermajority behaves correctly. He argued that current DVT implementations are operationally complex, require dedicated networking between nodes, and often rely on BLS signature linearity, a property he said does not align with quantum-secure designs.
Under his protocol-level design, a validator with at least n times the minimum balance could register up to n keys and a threshold m, capped at m <= n <= 16. The protocol would group the n “virtual identities” into one unit, credit rewards and participation only when at least m of n signatures back the same action, and require the same threshold to prove slashing conditions. The next step is community review of the coordination, latency, and signature-efficiency trade-offs.
