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. HTX (Huobi) is a real, operational cryptocurrency exchange founded in 2013 with 59M+ registered users and active trading as of June 2026 — it is not a scam, Ponzi, or exit fraud. A score of 8/CRITICAL is over-penalized under post-policy band semantics (0-19 = evidence of fraud/scam). The page's own content contradicts this placement: it describes HTX compensating hack victims, rejecting sanctions allegations, and continuing operations. The incidents driving the score are mixed in attribution: the two 2023 security hacks were suffered by the entity (and largely remediated), while the UK FCDO sanctions designation and documented $4.9B in Russia-linked flows represent genuine own-negligence or facilitation failures severe enough to warrant the WARNING band. The FCA civil proceedings (unlawful financial promotions, opaque ownership) and the SEC settlement (Rainberry, $10M, charges against Sun dismissed) add regulatory weight. A score of 25/WARNING captures the genuine severity — this is a major exchange with serious, active compliance failures and a sovereign sanctions designation — without misclassifying it alongside scams and Ponzi schemes. Outside skeptics can verify: the UK government sanctions list (RUS3619), TRM Labs' $4.9B flow analysis, the FCA proceedings page, and the SEC litigation release (LR-26496) all support this calibration.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
