Proposal: Physical Oracle layer for the Canton Network

Proposal: Zusei Physical Oracle (CPO)

Overview

Zusei is a decentralized Physical Oracle protocol that brings "Ground Truth" location data to the Canton Network via a cryptographic Proof of Presence (PoP) protocol.

Alignment with Canton Priorities

This project aligns with the Critical Infrastructure and Common Good priorities of the Canton Foundation. It provides a shared data layer that enhances the utility of:

1. RWA Protocols: Verified footfall for real-time asset valuation.
2. Insurance: Deterministic data for parametric business-interruption payouts.
3. AI Agents: A reliable location layer for autonomous on-chain execution.

Milestones & Acceptance Criteria

Milestone 1: Canton-Zusei Adapter Development

• Funding: 55,000 CNTN
• Deliverable: A functional middleware bridge and Move-based smart contracts.
• Acceptance Criteria: Successful end-to-end test of a hardware-generated "Proof of Presence" attestation being signed and stored on the Canton Global Synchronizer.

Milestone 2: Singapore CBD Reference Implementation

• Funding: 65,000 CNTN
• Deliverable: Deployment of 20 "Golden Nodes" in the Singapore Central Business District.
• Acceptance Criteria: 30 consecutive days of uptime for all 20 nodes with at least 500 verified unique visitor attestations successfully pushed to the Canton Testnet.

Milestone 3: Verified Visit Derivative (VVD) SDK

• Funding: 50,000 CNTN
• Deliverable: An open-source SDK for Canton developers.
• Acceptance Criteria: Documentation and sample code published on GitHub demonstrating how a third-party Canton app can call the Zusei Oracle to trigger a smart contract event.
