NON-CUSTODIAL // FINCEN EXEMPT

$0.00 Principal Funds Custody

Exempt under 31 CFR § 1010.100(ff)(5). Zero bank wire, ACH debit, or escrow accounts exist to be compromised.

FORMAL METHODS // MICROSOFT Z3

5/5 SMT-LIB2 Theorems Proved UNSAT

64-bit exact integer solver proves Net Equity (AR − AP) invariance and zero over-clearing before any ERP writeback.

CRYPTOGRAPHIC PRIVACY // RFC 9497

OPRF + 2-Edge SHA-256 Merkle Proofs

256-bit salted Tax ID blinding and local boundary proofs ensure 0 non-adjacent counterparty identities are ever disclosed.

PROPRIETARY IP // PATENT PENDING

U.S. Patent Pending (USPTO App. No. 64/194,062 · Docket GAUSSBOOK-PROV-001)

Ed25519-signed ASC 405-20-40-1 certificates and SHA-256 idempotency-key writebacks prevent any duplicate ledger deduction.
