Definition

A validator is an operator that participates in proof-of-stake consensus. Validators help secure a network by signing, proposing or validating blocks, maintaining uptime, and participating in governance.

Why it matters

Validators are not interchangeable reward endpoints. They are part of the network’s operating surface. Their security posture and reliability affect delegators, governance outcomes, and the credibility of the chain.

Validatus view

Validatus treats validation as critical infrastructure: secure first, observable by design, and accountable before delegation is requested.
