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.

The disputed_pct of 7.7% falls within the 0-10% approval band. The single disputed claim (claim_findings[24]) concerns a relisting date — the page states 'early 2025' but the event occurred November 2024 — which is a peripheral timing error, not a dispute of any core regulatory or financial allegation. The partially_supported claim (claim_findings[25]) reflects an internal inconsistency where the summary's '$170 million' figure predates two 2025 settlements now documented in the body, making the summary stat stale but technically accurate. No link rot was found, reviewer confidence is high at 0.88, and all coverage gaps are rated medium or low priority. The two issues should be corrected in the next revision but do not warrant withholding approval.","score_delta":0,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
