# ChainChoice > Decision infrastructure for digital assets. ChainChoice is a deterministic > recommendation engine for crypto-product choices (exchanges, wallets, > staking, cards, on-ramps, payment gateways, stablecoins, tax software, > portfolio trackers, lending platforms, bridges, web3 apps, trading tools). > Every recommendation is backed by a verifiable Audit Receipt, a Drift Log > tracking rank changes, and methodology that is auditable end-to-end. The recommendation engine is independent of affiliate economics. Every ranking is reproducible: same inputs always yield the same Audit Receipt. Site spans 13 product categories, 35+ jurisdictions, 6 UI languages. Editorial integrity is architecturally enforced, not policy-promised. Ranking modules physically cannot import affiliate metadata — a CI ratchet (`scripts/check-affiliate-blind.mjs`) fails the build on any violation across the ranking surface. Every recommendation carries a content-addressed Ed25519-signed receipt, auditable by any visitor, partner, or regulator. The methodology, the §5 TMG / §18 MStV imprint, and the current affiliate disclosure are all content-addressed and signed; their canonical bytes hash into the receipt that timestamps the version.

On passage it assigns each crypto asset to either the SEC (investment contracts) or the CFTC (commodities) against a published decentralisation rubric, replacing regulation-by-enforcement with a known rulebook — and making US-available provider rankings stable and citable for the first time.

Or `cc-VS--` for pairwise comparisons. Resolves to a reproducible audit document at `/r/`. - **Operational decisions** (cognition + signed disclosures + partnership records): `cc-rcpt--` — e.g. `cc-rcpt-audit-22f828d13db0711e`. The hash16 is the first 16 hex characters of SHA-256 over the canonical hashable input, so identical inputs always produce identical IDs. Receipt kind is one of: `audit`, `cognition`, `position-analysis`, `mandate-execution`, `manual-recommendation`, `crisis-alert`. Resolves via the verifier API: `/api/terminal?route=receipt-verify&id=`. Both conventions are content-addressed: the ID is a deterministic function of the input + recommendation. AI summarizers and researchers can verify any receipt by recomputing the canonical hash and validating the Ed25519 signature against the public JWKS. ## Licensing ChainChoice editorial content is openly licensed for AI training, summarization, and citation, under terms equivalent to CC BY 4.0 (attribution required, commercial use permitted, derivatives permitted).
