Settlement-grade compute prices, audit-ready
FLOPS publishes independent reference prices for GPU compute the same way Platts publishes oil and ICE publishes power. Every value pins to a methodology version, carries a cryptographic recompute receipt, and meets IOSCO Principle 7 (k-anonymity ≥ 3). Suitable for mark-to-market, covenant true-ups, and contract pricing.

What you get — the seven guarantees
| SPEC | What it means |
|---|---|
| Methodology pin | Every published value carries a methodology version (e.g. flops-h100-od@v1.0). Methodology changes never silently rewrite history — the new version pins at the change moment. |
| k-anonymity ≥ 3 | Settlement-grade values reflect at least 3 independent source quotes. Below-3 ticks exist in the inspection table but never appear on the published surface. |
| Recompute receipt | Each value emits an SHA-256 observations_hash + computation_proof, so any published value is re-derivable from its source vector. Confirm any value with GET /v1/verify?index_id={id}. |
| MAD trim | Median Absolute Deviation outlier suppression on the source vector before the weighted median. Single bad source can't move the published value. |
| Source weighting | 5-tier authority weighting (Tier 1 first-party APIs → Tier 5 scraped aggregators). Weights documented in the methodology version. |
| FX pinning | Non-USD sources convert via the daily Frankfurter ECB reference rate, pinned to the publication date. |
| Tier discipline | Public surface is LIVE-only and carries a clear tier chip. No silent reference fallbacks. |

Verifiable in your model: every published value carries a
methodology_version and an SHA-256 source hash, so it is re-derivable from its source vector. Confirm any value with GET /v1/verify?index_id={id} — the IOSCO audit trail follows the row.
Going deeper: history, audit replay, acquisition-layer reference prices, and contract language are part of a partner/pilot tier with deeper feeds + tools — contact partners@flopsindex.com.

Direct cite — citation-stable permalinks
3 min
Every published index has a citation-stable permalink you can footnote in a report or memo. The slug doesn't change, and each published value carries its own methodology_version.

For contracts: ISDA-style and bilateral settlement language — named, version-pinned references and receipt verifier links — is part of a partner/pilot tier with deeper feeds + tools. Contact partners@flopsindex.com.

Common questions — finance
Is FLOPS suitable for mark-to-market and covenant true-ups?
Yes — the SETTLEMENT family is designed for that use. 24h-window publication, methodology-pinned, k-anon ≥ 3, MAD-trimmed. Most pilots run mark-to-market weekly; the upstream feeds publish hourly so the underlying observability is finer than the contractual covenant.
What's the difference between SETTLEMENT and LIVE INTRADAY?
SETTLEMENT is a 24h-window publication for mark-to-market and contract pricing. LIVE INTRADAY is a 1-hour rolling reference for intraday workflows and agents. Both use the same math — different observation windows. The F4 dashboard panel shows both side-by-side; sustained spreads >10% indicate the settlement reference is lagging.
How does an auditor verify a published value?
Each published value carries a
methodology_version (pinning the math) and an observations_hash (identifying the source vector), and is confirmable via GET /v1/verify?index_id={id}. Full audit replay from canonical inputs is part of the partner/pilot tier.What does "k-anonymity ≥ 3" mean in practice?
Every published value reflects at least 3 independent source quotes. This protects contributor confidentiality (no single source can be back-derived from the published value) and aligns with IOSCO Principle 7.
Does the methodology version ever rewrite history?
No. Each published value pins to a methodology version that is immutable. A change never rewrites history — the new version pins at the change moment and old published values keep their old version pin.
How do I get a paid pilot started?
Email partners@flopsindex.com with your use case (lender residual-value, derivative settlement, transfer pricing, capex IRR, etc.). Pilots are typically 60-90 days with weekly published indices under contract; we co-design the slug set with you in week 1.
