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 page content is accurate and all six claim findings are supported (disputed_pct = 0%). The review finds MEXC is a large, actively operating exchange ranked #3-4 globally by perpetuals open interest with a 9/10 CoinGecko trust score (claim_findings[0]), which is inconsistent with a CRITICAL band classification. The incidents cited on the page — the Seychelles corporate dissolution (claim_findings[2]), six multi-jurisdiction unlicensed-operations warnings (claim_findings[3]), the resolved White Whale account freeze (claim_findings[1]), and premarket scam allegations attributable to third-party sellers (claim_findings[4]) — do not collectively meet the CRITICAL threshold of confirmed fraud, exit scam, or systemic misappropriation of customer funds (claim_findings[5]). A score of 28 (WARNING band) correctly captures the material and unresolved regulatory exposure and corporate opacity without treating a still-operating major exchange as fraudulent. A positive score delta of +10 is warranted to move the score from 18 to 28, correcting a demonstrably miscalibrated severity band. Reviewer confidence is 0.82.","score_delta":10,"sequence_num":5,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
