Covalidation

Covalidation

1. Overview

The Covalidation Service (CVS) is a managed infrastructure solution for the Canton Network designed to eliminate single points of failure for Wallets and Applications. By multi-hosting parties and distributing party validation responsibilities across a redundant, high-availability network, CVS ensures services remain online, secure, and performant.

Core benefits include:

  • Unrivaled Resilience: 2/3 confirmation threshold protects operations against node compromises.

  • Continuous Availability: High availability infrastructure ensures near-zero downtime.

  • Operational Simplicity: Digital Asset and another partner manage the dedicated validator node, while you retain control over topology and DAR vetting.

  • Business Continuity: 30-day historic data retention facilitates rapid disaster recovery.

2. Getting Started

Contact Digital Asset Sales to join the covalidation network.

Onboarding

Once registered, a high-level overview of the onboarding process is below:

  1. Third node operator: Choose a third party node operator to host parties on a third validator.

  2. Config: Validator operators inform each other of their validator IDs so that the covalidators can be configured accordingly.

  3. Dars: A central repository where dars are pulled from is created.

  4. Topology: Each time a topology transaction is created to multi-host a party, the covalidating nodes automatically approve it if it meets the pre-agreed structure.

  5. Transaction: When a multi-hosted party initiates a transaction, the confirmation nodes validate the transaction against the hosted dars.

  6. Config Changes: New dars and topology changes can be requested.

3. Architecture & Security

  • 2/3 Confirmation Threshold: Transactions require multi-party validation, preventing any single node from independently validating transactions.

  • Node Redundancy: Multi-cloud/multi-infrastructure setup.

  • Data Retention: Historic ledger data is retained for 30 days to aid node recovery.

  • KMS Integration: All node keys are managed via KMS for enhanced security.

4. Node Operators
