## Overview

The **Covalidation Service (CVS)** is a managed infrastructure solution for the Canton Network that eliminates single points of failure for wallets and applications. By multi-hosting parties and distributing validation responsibilities across a redundant, high-availability network, CVS helps ensure services remain secure, available, and resilient without requiring organizations to operate every aspect of the infrastructure themselves.
