e-PN: The Sovereign Promissory Note
An electronic promissory note (e-PN) issued by ISET.finance is secured against a PPSR-registered payment intangible. It satisfies UNCITRAL MLETR 2017 uniqueness and control requirements through the SHA3-256 Consent Ledger.
Unlike a traditional promissory note — which is a claim on a borrower's future income — an ISET e-PN is a claim on a registered asset that already exists on a government registry with prior interest from its timestamp.
The instrument answers three foundational questions before credit is extended or risk is accepted: does the collateral exist, is it encumbered, and has it been pledged elsewhere? The PPSR registry, Trust Deed, and Consent Ledger answer all three.
- ✓ Collateral exists — PPSR registry, verifiable
- ✓ Not encumbered — priority from registration timestamp
- ✓ Not pledged elsewhere — Consent Ledger records every disposition
