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.

Twenty claims were fully confirmed by independent sources, three are partially supported due to minor wording imprecision (claim_findings[2] on epoch timing, claim_findings[4] on Formal Land's relationship to Nomadic Labs, claim_findings[3] on USDC vault specifics), and one is unverifiable from available public sources. The disputed_pct of 4.2% falls well within the 0-10% approval band. Three high-priority coverage gaps remain open — on-chain verification of the LAB position, audit PDF scope, and LAB supply concentration — but these call for page expansion rather than correction, and do not undermine the accuracy of what is currently published.","score_delta":0,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
