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

  1. 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.
  2. 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.
  3. 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.

Verdict: over-penalized. Page content is treated as accurate; the trust_score band is miscalibrated. MEXC is a large, actively operating centralized exchange — ranked #3-4 globally by perpetuals open interest and carrying a 9/10 CoinGecko trust score as of June 2026 — that does not meet the CRITICAL band's threshold of 'evidence of fraud/scam.' The incidents driving the score are: (1) administrative dissolution of its Seychelles holding entity (not an operating entity collapse), (2) unlicensed-operations warnings from six regulators (a WARNING-tier regulatory profile, not a fraud finding), (3) a high-profile $3M account freeze that was resolved with a public apology and fund release, and (4) premarket collateral disputes attributable to third-party sellers on its platform. None of these constitute the exchange itself running a Ponzi, executing an exit scam, or misappropriating customer funds on a systemic basis. A score of 28 and WARNING band accurately reflects the material but unresolved regulatory exposure, the opacity of its current corporate structure after the Seychelles dissolution, and the pattern of account-freeze complaints — without treating a still-operating major exchange as fraudulent.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
