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

  1. 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.
  2. 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.
  3. 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 (indices 0-5) are marked 'supported' with 0% disputed claims and reviewer confidence of 0.85. The review establishes that the page's current score of 32 (stored as 20) is materially too harsh because three incidents on the timeline — the Cream Finance $130M hack (claim_findings[1]), the Alpha Homora/Iron Bank $37M exploit (claim_findings[2]), and the Iron Bank $32M bad-debt freeze (claim_findings[5]) — were misattributed to Yearn when Yearn was either a bystander, a recovery helper, or an indirect depositor-protectee. Confirmed Yearn-specific losses are approximately $33M, all from legacy deprecated contracts, with V2/V3 vaults unaffected (claim_findings[3]). There is no evidence of fraud, Ponzi mechanics, or regulatory conviction (claim_findings[4]). The page content is accurate and must remain published; only the trust-score band requires correction from WARNING to CAUTIONARY (score 58), warranting a positive delta of +38.","score_delta":38,"sequence_num":5,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
