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.

Primary regulatory claims — the May 20, 2026 OFAC action date, six Ethereum addresses and their attributions, 11 designated individuals, entity names, executive order citations, FTO designation date, and the 'eighth designation' count — are all confirmed by multiple credible sources including TRM Labs, Scorechain, Chainalysis, DEA press releases, and archived Treasury documents. The most significant inaccuracy is in the description of Jimenez Castro's 2023 wallet activity: the page states '$740,000 over a two-month period beginning January 2023,' but other sources indicate the period ran approximately March 2022 to February 2023 (~11 months); the $740,000 amount itself is confirmed. A secondary inaccuracy is describing the Gonzalez Penuelas reward as a 'DEA reward' when it is formally a State Department Narcotics Rewards Program offer. One financial typology claim (Chinese money laundering fees of 0.5-5%) could not be independently corroborated beyond the Scorechain source.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
