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 are supported — the page content is accurate and the page stands. The reviewer (confidence 0.82) finds the current score of 45/WARNING overstates risk because: the 2017 $31M treasury theft (claim_findings[2]) was external fraud suffered by Tether, not operator misconduct; both regulatory settlements (claim_findings[0] and [1]) were civil, paid without fraud convictions, and relate to a documented prior period (2016–2019); and the entity has since engaged KPMG for a full Big Four audit (claim_findings[4]), a material transparency step absent from the page. The page also carries a stale market-cap figure and a minor timeline date error (claim_findings[3] and [4]), but these are content refresh items that do not affect the calibration verdict. Balancing confirmed, now-partially-resolved regulatory violations against the absence of fraud convictions and recent transparency progress, a score of 52 in the CAUTIONARY band is the appropriate calibration. A positive delta of +7 is applied to move the score from 45 to 52.","score_delta":7,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
