Verify a decision
Every moderation decision on AVOID.NET is anchored to the Solana blockchain. You don't have to trust us — you can verify cryptographically that we committed to a verdict at a specific moment and have not rewritten it.
How verification works
- We commit. When a moderator accepts/rejects a submission, we serialize the decision into deterministic UTF-8 bytes (
payload_canonical_string), hash it with SHA-256, encode the digest as base58, and write it to Solana inside an SPL Memo v2 transaction. - We store the bytes. The exact bytes we hashed are stored alongside the decision in our database. Anyone can read them and recompute the hash in any language.
- You compare three values. Database hash, your independently-recomputed hash, and the hash inside the on-chain memo. If all three match, the decision is authentic and timestamped.
The on-chain memo format is
AVOID.NET|v1|h:<b58-sha256>|d:<id>|t:<iso>Find a signature on any investigation page's decision log, or run python -m src.verify_decision --signature <sig> for a CLI check.

All six claim findings (claim_findings[0] through claim_findings[5]) are supported, and disputed_pct is 0% — the page content is accurate and stands. The current score of 32 (WARNING band) is demonstrably too harsh: every one of the 12 timeline entries documents third-party actors exploiting Cardano's brand and user base; none are attributable to Cardano itself (claim_findings[4]). The page's own language frames Cardano as a victim target, not a perpetrator (claim_findings[0]). Meanwhile the score omits material legitimacy counterweights — Swiss non-profit governance, CME futures launched February 2026, multiple spot ETF filings, and inclusion in the U.S. national digital asset reserve (claim_findings[3]) — that a properly calibrated score must weigh. A delta of +40 corrects the score to 72 (VERIFIED), consistent with the reviewer's recommendation and supported at 0.91 confidence.","score_delta":5,"sequence_num":7,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
