ProtoLedger Money Standard
Evaluating money and the systems that issue it
v4.0 · June 2026 · Apache 2.0 · Open for Community Review
ProtoLedger is an open standard for evaluating money and the systems that issue it. It reports two objects on two scales that are never summed — Monetary Fitness (M, Layer A) and System Soundness (S, Layer B) — plus a disclosure layer (Layer C) for contested values and mechanism facts that are recorded but never scored.
Each property carries a Today score (Achieved-tier evidence only) and a Ceiling score. Scoring is outcome-based, evidence-graded, and tail-aware. Published under the Apache 2.0 licence — fork it, build on it, or challenge a score with evidence.
Money Standard v4.0
The full specification: subject-instance rule, 5 archetypes with gates, 17 scored properties, 8 disclosure axes, the scoring model, and the challenge process.

Every major subject-instance assessed on the two axes, with the interactive Terminal for archetype weighting and Layer C filtering.
Open the Index →Layer A — Monetary Fitness
Seven properties for whether it works as money. The unweighted mean of an asset's Layer A Today scores is its M value.
Layer B — System Soundness
Ten properties for whether the system behind the money is sound. The unweighted mean of an asset's Layer B Today scores is its S value.
Layer C — Disclosed, Not Scored
Eight axes — four contested values, four mechanism facts — recorded and disclosed, never scored. Used as filters in the Terminal.
Gates
Each archetype names conjunctive gates; a gate failure caps the verdict and must be stated. Universal gates apply to all archetypes:
- A1 < 7 Today — not "money in use" / "ready today".
- B1 < 7 or B2 < 7 Today — not a "sound system".
- Ceiling scores never satisfy a "ready today" gate — only a verdict explicitly labelled ceiling.
Full per-archetype gates (A–E) are in the whitepaper.
