Private RWA Settlement Layer — Architecture Summary

1. What This System Does

The Private RWA Settlement Layer enables confidential settlement of real-world asset (RWA) contracts while keeping settlement results publicly verifiable.

It uses two layers:

• Midnight (Private Layer)
  • Stores confidential contract terms
  • Executes settlement logic privately
  • Generates zero-knowledge proofs (ZKPs)
• Cardano (Public Layer)
  • Verifies those proofs
  • Publishes settlement results
  • Creates a public audit trail without revealing sensitive details

This allows enterprises to keep business data private while giving regulators and investors cryptographic proof of correctness.

2. Simple Example

Company: GreenChain Logistics

Use Case: $250,000 supply-chain invoice financing

1. GreenChain uploads private contract terms to Midnight:
   • invoice amount
   • due date
   • interest rules
2. Midnight executes the settlement logic privately and generates proofs:
   • payment is on time
   • amount matches contract
   • interest calculation is correct
3. Cardano verifies the proofs and publishes a public result:

Asset: RWA-INV-0421

Status: Settled on Time

Proof Verified: TRUE

Investors and regulators can confirm the settlement outcome without seeing any of the private contract data.
