Netting Process

Obligations are recorded throughout the settlement window, compressed through four layers of netting, priced at oracle-determined FX rates, and settled as consolidated net positions.

Settle

Net positions only

Sub-threshold net positions (<$100K default) carry forward to the next window (max 3 windows) using a CHIPS-model approach, expanding the netting pool across windows for additional compression.

Capabilities

01

Multilateral Netting

Per-corridor multilateral netting with O(n) complexity. Configurable settlement windows with oracle-priced FX at window close. ISO 20022 CBPR+ native obligation recording.

02

Cross-Corridor Netting

Second layer of netting across corridors sharing the same currency. Additional savings on residual net positions after per-corridor netting. Effect scales with every new corridor per currency.

03

Bilateral Pre-Netting

Per-pair bilateral position tracking via recordBilateralObligation. Single transaction records sender debit + receiver credit + bilateral flow data. Foundation for SWIFT pacs.008 settlement instruction generation.

04

Residual Carry-Forward

CHIPS-model carry-forward. Sub-threshold net positions carry to the next window (max 3), expanding the netting pool across windows. Configurable per corridor.

05

Cryptographic Privacy

Pedersen commitments (BN254) for homomorphic netting on encrypted values. AES-256-SIV metadata encryption. Bulletproofs range proofs (70ms proving, no trusted setup). Shamir's Secret Sharing for key distribution.

06

Post-Quantum Authentication

ML-DSA (FIPS 204) deployed via cloudflare/circl. Modes 44/65/87 supported. Hybrid Dilithium+ECDSA available. Batch verification and on-chain key registry.

Multi-Tenancy

Per-corridor isolation on a shared chain. All Settlement Computer products coexist with independent configurations.

Access Control

6-level role hierarchy with per-corridor RBAC:

  • GOVERNANCE — master key, full visibility
  • ADMIN — corridor-level administration
  • OPERATOR — netting window management
  • PARTICIPANT — obligation recording
  • DELEGATE — scoped, time-limited access
  • OBSERVER — aggregate statistics only

Corridor Isolation

  • Idempotent corridor creation
  • Per-corridor configuration limits
  • Per-corridor privacy levels (0/1/2)
  • Independent settlement windows
  • Jurisdiction-specific compliance rules
  • Failure isolation between corridors

Participant-Sovereign Data Delegation

Participants control who sees their data. Delegation is granular, time-limited, revocable, and produces an immutable on-chain audit trail.

Delegation Model

  • grantViewAccess — granular scope, expiry, revocable
  • revokeViewAccess — instant, on-chain
  • Scopes: ALL, CORRIDOR, COUNTERPARTY, TIME_RANGE
  • On-chain audit trail (DelegateDataAccessed event)
  • canGenerateProofs flag for proof delegation

Designed For

  • Regulators and central bank supervisors
  • External auditors and compliance officers
  • Correspondent banking partners
  • Insurers and credit assessors
  • Legal and dispute resolution
