OFN — the receipt rail
Status: pre-launch. This page describes target design; this document does not establish a deployed service.
Current owner boundary — 13 October 2026: OFN is the separately accountable issuer of economic receipts. It is not LIQUID, which owns commerce, exchange, liquidity, and payment terms, and it is not an eighth Skyzai product owner. Its standard and integration are design/proof work; these pages do not establish a live issuing service. See OFN Receipt Protocol.
What it is
The Open Finance Network (OFN) intends to issue a receipt that binds a specific economic event to its source, participants, applicable authority evidence, execution evidence, time, and result. A participating product can submit or reference the event; OFN has the separate issuance responsibility, and verifiers check the resulting receipt. A receipt records what the available evidence supports. It does not itself authorize the act, settle a payment, establish tax treatment, or prove a lawful outcome.
Status
The receipt standard and bounded adapter tests are design and local evidence, not proof of a deployed OFN issuer, anchoring network, or external settlement. Issuance needs a defined event schema, signed or otherwise attributable source evidence, valid authority for the exact consequence where required, execution evidence, issuer controls, and replayable/exportable output. Integration with LIQUID or another product must pass those gates for each event type.
Historical universal receipt-rail and substrate framing
The July package model described OFN as Noosphere infrastructure funded by other products, with a universal receipt for every material act. That model is retained as a design ambition, not a live issuance or product-owner claim.
Proof · Noosphere infrastructure — never sold. Every material act becomes an exportable, anchored receipt. The nervous system.
Substrate law. Funded by the products above it; rentable by none; η=0 is the copyleft.
Receipt discipline is practiced commercially (a separate Phase-1 venture); the anchoring rail itself is being built. G4 invariant: every deliverable ends in a dated receipt.
