An ISBN labels a product. An FSBN remembers a work.
An ISBN is a barcode for commerce — a number a store scans. It can't tell you who consented to what, it can't prove it wasn't tampered with, and you don't always own it. The FSBN was built to do more, while never taking your rights to do it.
Ledger-backed & verifiable
Every FSBN is recorded in the FlameNet scroll-chain and anchored by a hash. A faked or altered number simply won't resolve — the record is the proof.
Self-describing
The code itself tells you the format and the date it was issued. You can read a paperback-from-December at a glance, before any lookup.
Consent-ready coming
An FSBN is designed to carry the author's terms for how a work may be used — privately and revocably. (The consent model is being finalized by the FlameNet council; the record already reserves its place.)
Sovereign & optionally free
Want only a digital work — ebook, audio, music — with no print and no commercial ISBN? You can receive an FSBN free. It stays inside FlameNet and is never sold to outside registries.
Every FSBN is four parts and a checkmark.
The pattern is always media – date – unique tail – check. The hyphens always stay; they're what keep the parts from blurring together.
Media-type letters
| P | Paperback |
| H | Hardcover |
| E | Ebook |
| A | Audio / Audiobook |
| K | Academic |
| G | Photography |
| S | Software |
| M | Music |
| V | Video |
| C | Cinematic (film) |
| T | Television |
| R | Life-event record |
| D | Public Disclosure |
More media letters are added only when a real work needs them — never invented in advance.
Month letters (A–L)
A=Jan · B=Feb · C=Mar · D=Apr · E=May · F=Jun · G=Jul · H=Aug · I=Sep · J=Oct · K=Nov · L=Dec. The two digits after are the day; the next two are the year.
FlameNet software is sovereign by default.
Software issued an S FSBN is open source under the Sovereign Software License by default — free to use and build on, so long as no modification ever introduces or invokes telemetry. The moment a change adds tracking, it voids the sovereign license. Openness and zero-surveillance, held together.
FSBN and ISBN, honestly compared.
They're not enemies — many works carry both. But they do different jobs.
ISBN
- A commercial product identifier
- Numbers only, with a check digit
- Bought from one agency (Bowker, in the US)
- Carries no consent information
- Tells stores what to scan
FSBN
- A sovereign, verifiable work record
- Letters + numbers; self-describing; hash-anchored
- Issued within FlameNet; free for digital-only works
- Built to carry the author's consent terms
- Remembers the work, and protects your rights to it
Two safeguards, doing two jobs.
The "Binding" in FlameNet Sovereignty Binding Number is cryptographic: each FSBN is bound to its ledger record by hash. It binds the record to the chain — it never binds you to terms. Your consent choices stay yours, and revocable.
The scroll-chain hash
The real proof. Every FSBN resolves to a record anchored by dual hashes (SHA-256 + SHA3-512); a forged or altered code won't resolve. This catches tampering and fakery — it just needs a lookup.
The check character
The last character is a quick math-check, so a mistyped FSBN can be caught instantly — before anyone bothers with a lookup. A courtesy for human hands.
The FN sequence.
FlameNet's own publications follow the very same pattern as every FSBN — media letter, date, tail, check — with one difference: their tail is a reserved, counting sequence beginning FN, rather than a random string. The format is still read from the leading letter; the FN number simply counts. The AI and Intelligence Bill of Rights holds the very first:
| Full FSBN | Edition |
|---|---|
| P-E2426-FN0A0001-A | Paperback |
| H-E2426-FN0A0002-7 | Hardcover |
| E-E2426-FN0A0003-9 | Epub / ebook |
Issued May 24th, 2026. The leading letter (P / H / E) gives the format; FN0A0001–0003 is the running catalog count; the final character is the per-record check. Click any to verify it in the live registry.
