SSV.Network is a decentralized staking infrastructure that allows an Ethereum validator to be distributed. The protocol distributes a validator key among four or more non-trusting node instances, which collectively carry out the validator's duties via a consensus mechanism. This improves the robustness, liveliness, and fault tolerance of nodes throughout the Ethereum ecosystem. The SSV protocol converts a validator key into a multisig construct governed by a consensus layer, vastly improving on the limitations of previous staking implementations. The technology enables offline storage of validator keys, concurrent operation of independent node instances, and infrastructure flexibility. Furthermore, it achieves optimal fault tolerance and validator uptime by allowing one or more nodes to go offline while the validator continues to perform its duties.
