Scaling the Consensus Layer - Distributed Validator Technology

Distributed validator technology (DVT) is presented as a way to remove single points of failure from Ethereum validators by splitting the validator signing key and running the validator across redundant, geographically spread operators. The article describes the design as DKG plus threshold signatures plus a consensus layer, with IBFT chosen for the middleware because it tolerates one-third failure and allows fast leader changes. It profiles three DVT projects: Obol Network, whose Charon middleware runs across operators, and SSV Network, which reports 224 validators across 24 operators and 7,168 ETH staked as of August 2023. Diva Labs splits keys into 16 shares and plans a mainnet launch in Q4 2023.
