Node Operations 2 - Canton Participant Nodes

The Canton Participant Node serves as the institutional gateway to the settlement layer. While Rapid Chain manages high-speed execution, the Participant Node functions as the "Legal Memory" and the ultimate system of record for the network.

13.1. System of Record and Legal Finality

The primary role of the Canton Participant Node is to provide an authoritative environment where asset ownership is recorded with legal rigor.

• Legal Sovereignty: This node ensures that ownership changes are finalized according to institutional identity frameworks and regulatory requirements.

• Asset Custody Recording: The Participant Node maintains the official record of asset custody, ensuring that no execution-level state change becomes final until it is committed to this layer.

• Regulatory Compliance Ledger: It acts as a dedicated ledger for compliance, where all state transitions are auditable and deterministic.

13.2. Privacy and Data Sovereignty

In alignment with the "Need-to-Know" privacy model, the Participant Node ensures that institutional data remains protected.

• Localized Data Segregation: Unlike public validators, a Participant Node only stores data and transaction history relevant to the specific parties involved.

• Confidential State Updates: It ensures that while the Global Synchronizer coordinates the transaction, the actual sensitive business logic remains encrypted and isolated within the node.

• Sovereign Control: Operators have full technical control over their own ledger, preventing third parties from unilaterally forking or altering their specific state.

13.3. Technical Synchronization and Deployment

The Canton Participant Node connects to the Global Synchronizer to enable bridgeless, atomic interactions with Rapid Chain.

Deployment Configuration: Linking Execution to Settlement The following command structure is used to register an institution on the network and bind the Rapid Chain execution logic to the Canton settlement layer.

# Registering the Institution on the Canton Network
canton-participant register-party --moniker "Institutional-Entity-01"

# Binding the Rapid Chain Execution Result to Canton Settlement
# Ensures all 'Financial Intents' are translated into deterministic instructions
canton-participant bind-adapter \
  --rapid-rpc "https://rpc.rapidchain.io" \
  --sync-mode "atomic-commit" \
  --privacy-standard "institutional-grade"

13.4. Hosting Models for Institutions

To meet varying security and infrastructure needs, the Canton Participant Node supports multiple hosting paradigms:

• On-Premise Deployment: For maximum security, allowing institutions to maintain physical control over their hardware and encryption keys.

• Managed Cloud Instances: Utilizing vetted cloud providers to ensure high availability while respecting jurisdictional data residency rules.

• Global Synchronizer Alignment: All hosting models require a direct connection to the Canton Foundation’s Global Synchronizer for cross-domain composability.
