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.

One material factual error was identified: the timeline entry for April 8, 2018 states '32,000 affected investors organize a protest' when every cited English-language source describes attendance as 'dozens' — 32,000 is the total alleged victim count, not protest attendance. Two CoinTelegraph URLs are dead links (link rot). The specific banner text quoted from the protest is not independently verifiable in English-language sources and may originate from untranslated Vietnamese reporting. The PM directive date of April 12 is uncertain (April 12, 2018 was a Thursday; one source implies Wednesday, another implies Friday April 13). The trust score calibration (very low) is appropriate for a well-documented Ponzi exit scam of this scale.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
