# Distributed validators: how several machines share Ethereum signing

Distributed validator technology, or DVT, lets several machines coordinate one Ethereum validator using shares of its signing key. A required threshold of participants signs duties together, so some individual failures can be tolerated. It adds coordination software and operational costs, and it does not change who controls the validator’s withdrawal address.

## Key facts

- **One validator:** Several operators can jointly perform duties for one validator identity. ([Distributed validator technology](https://ethereum.org/en/staking/dvt/))
- **Threshold:** Only a sufficient number of participating key shares can complete signing. ([Distributed validator technology](https://ethereum.org/en/staking/dvt/))
- **Separate custody:** DVT distributes validator signing, not withdrawal-address ownership. ([Distributed validator technology](https://ethereum.org/en/staking/dvt/))

## Coordinate signatures rather than duplicate a full key

Ordinary independent copies of a validator key can sign conflicting messages. DVT instead coordinates participants and combines partial signatures according to a shared protocol. Distributed key generation can create shares without placing the complete key on one machine.

Other setups may split an existing key. The key-generation and custody model should therefore be checked for the particular deployment.

## A three-of-four cluster has a defined limit

In a hypothetical cluster requiring three of four operators, one offline operator leaves three available to sign. Two offline operators leave only two, below the threshold. The example assumes the remaining operators and coordination work correctly.

This tolerance is not an unlimited uptime guarantee. Shared infrastructure, a common software bug or communication failure can affect several participants at once.

## More resilience also means more machinery

DVT introduces middleware, inter-operator coordination and additional machines. It can add latency, cost and software dependencies. Check cluster management, supported clients and recovery procedures before treating it as a simple backup switch.

A staking pool can use DVT, and an individual operator can use it too. Pooling contributions and distributing signing are different choices.

## Questions

### Does DVT reduce the protocol’s validator stake minimum?

DVT changes how signing is operated. It does not itself change Ethereum’s activation requirements or create a pool of financial contributions.

### Does every DVT cluster require three of four operators?

No. That is one threshold example. Cluster size and required participation are deployment choices with different failure tolerance.
