Deterministic Settlement Confirmation Blocker

We are encountering a network‑level blocker when attempting to activate deterministic settlement logic for our node. Before any transaction submission, the network should confirm (on‑chain) whether our CIP‑0056‑compliant package is valid and whether deterministic settlement should proceed or be rejected.

This confirmation is not occurring, preventing our node from entering the settlement corridor.

Environment

• Node type: Deterministic settlement node (KRO Brokers)
• Architecture: CIP‑0056 splice amulet + deterministic “If X → settle” logic
• SDK: 3.4.11
• Package: canton-network-token-standard-kro-cer-token
• Version: 0.4.0
• Hosting participants: Multiple (requires idempotent vetting)

Expected Behavior

When uploading a CIP‑0056‑compliant DAR package, the network should:

1. Validate the package
2. Confirm CIP‑0056 interface compliance
3. Activate deterministic settlement logic
4. Allow transaction submission
5. Enforce deterministic outcomes:
   • If X is true → settle
   • If X is false → reject

This is the standard deterministic flow for our node using CIP‑0056 splice amulet packages.

Actual Behavior

Upon uploading the DAR package, the network:

• Accepts the upload
• Does not perform the required on‑chain confirmation
• Does not activate deterministic settlement logic
• Blocks transaction submission entirely

This results in a pre‑transaction validation deadlock.

Impact

Network Growth & Expansion

• Deterministic counterparty nodes cannot process our transaction, and the network traffic fee isn’t earned
• Our CIP‑0056‑compliant packages cannot propagate
• Counterparty validators cannot ingest our instrument package
• Settlement corridors cannot expand

Node Security & GRC Posture

• We cannot submit transactions without deterministic validation
• We cannot bypass compliance checks
• We cannot risk non‑deterministic settlement behavior
• This is a hard GRC blocker, not a soft technical issue

Request to DevRel

We request DevRel to

· Confirm the appropriate resolution path. We have our DAR package available and can securely provide it for review if needed.

Requested outcomes:

1. Activate deterministic settlement logic
2. Unblock transaction submission
3. Restore deterministic “If X → settle” behavior

This is required for both network‑level benefit and our node‑level compliance with deterministic posture.

Additional Context

Our node architecture is intentionally built on deterministic settlement standards, where outcomes are binary and rule‑driven:

• If X is true → settle
• If conditions are met → settlement proceeds
• If conditions fail → deterministic rejection

As part of our design policy, we use the CIP‑0056 splice amulet package across all operational flows to ensure:

• deterministic ingestion of instrument packages
• interface‑level validation against canonical CIP‑0056 flows
• seamless counterparty workflow integration for compliant settlement

This package is foundational to our deterministic posture and is required for predictable, rule‑based settlement behavior across hosting participants.

Thank you for your help in resolving this blocker.
