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 concrete factual error was identified in claim_findings[19] (timeline entry for April 8, 2018): the page states 'approximately 32,000 affected investors organize a protest,' but every cited source (Vice, Vietnam Investment Review, CoinDesk) describes protest attendance as 'dozens' — 32,000 is the total alleged victim count, not the crowd size. This conflation should be corrected before the page is considered final. Four claims are partially supported due to ambiguity about whether the 48% or 40% monthly return figure applied specifically to Pincoin versus iFan; this is a minor precision issue, not a fabrication, and does not materially change the fraud characterization. Two CoinTelegraph URLs have link rot (medium-severity section), and two high-priority coverage gaps remain: post-2018 legal outcomes and on-chain fund tracing for a $660M alleged fraud.","score_delta":-5,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
