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 hold up: the June 22, 2026 OFAC designation, the three bureau de change firms, the co-designees and the Nigerian asset freeze are confirmed (claim_findings[0], [1], [8], [10]). The page's 'first OFAC action targeting ISIS crypto financing in West Africa' framing, repeated in the summary and a section heading, is not supported by any source, and the sources describe Muhammad's role as cash and bureau de change based (claim_findings[4], [5]). The timeline date for the TRM analysis is off by one day (claim_findings[7]) and the stated aliases could not be found in the sources checked (claim_findings[2]). The penalty sits at the lower end of the band because the underlying designation is sound, the subject remains sanctioned, and no material omissions were found.","reviewer_def_hash":"3839668b232611e5b26db72079d64745f8e57e919b8a379e79b44ba4a52c845b","score_delta":-16,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
