COMPLIANCE & EXPLOIT TESTING

Simulate anomalies to trigger contract and circuit rejections

1. Credit Line Exploit Attempt

Attempt to settle an invoice of $120,000 when approved credit limit is $100,000.

Expected: Witness Range-Check Assertion Error

2. Double-Factoring Fraud

Attempt to reuse the same invoice ID (INV-4029) to borrow against or settle a second time.

Expected: On-Chain Nullifier Registry Revert

3. Expired Payment Term Settlement

Submit an invoice with a due date of 1 hour in the past. Ledger rejects terms compliance.

Expected: Ledger Time-Constraint Violation

Core Cryptographic Features

Mathematical Guarantees of Privacy & Security

01

Range-Proof Auditing

Proves invoice amount matches corporate credit line limits (amount ≤ credit_line) without ever exposing the numerical value of either on-chain.

02

Poseidon2 Nullifiers

Locks invoice uniqueness natively. The smart contract ensures a nullifier can only be settled once, mathematically ending double-factoring invoice fraud.

03

Protocol 26 MSM Speed

Utilizes native bn254 multi-scalar multiplication host functions. Lowers proof validation latency and reduces smart contract transaction costs by >75%.

Procurement Security Review

"A competitor scraped our raw payment records off the blockchain, discovered the exact wholesale price we pay our main parts supplier, and used it to underbid us on a multi-million dollar manufacturing contract. Obscura prevents this catastrophe."
