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.

The core facts (charges, ages, penalties, date, token list, employment dates) were confirmed by The Block and Cointelegraph (claim_findings[0], [2], [3]). The unverified items are the judge and residences, the defense statement attributed to Xiang's lawyer (not in the cited source), the Kaiko wallet analysis and the Comer letters, and the last two were not fetched. The page also relies only on trade press, with no SDNY press release or complaint cited. Because the review found no contradictions and its confidence was moderate, the penalty is at the mild end of the band.","reviewer_def_hash":"3839668b232611e5b26db72079d64745f8e57e919b8a379e79b44ba4a52c845b","score_delta":0,"sequence_num":6,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
