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 major centralized exchange with over 47 million users that remains operationally active as of mid-2026. It is not a fraud, Ponzi scheme, or exit scam. The CRITICAL band (0–19) requires evidence that the entity itself perpetrated fraud; the page's own evidence does not meet that threshold. The September 2023 hot wallet hack resulted in a full fund recovery via a white-hat bounty with zero net user loss. The November 2023 HECO bridge exploit (~$99–115M) was caused by a compromised external bridge operator private key — a third-party infrastructure attack — not fraud by HTX. The SEC charges against Justin Sun, which were the most serious fraud allegations, were permanently dismissed with prejudice in March 2026 (the page's own timeline records this on Mar 5, 2026 but no score revision was made). Proof-of-reserves integrity concerns (Protos Jan 2024 investigation into USDD double-counting and 92% USDT deployment to DeFi) are material but unconfirmed as deliberate fraud. Importantly, the page is missing the two most serious current developments: the UK government sanctioning Huobi Global S.A. on May 26, 2026 for allegedly facilitating $1.5B in Russia sanctions-evasion, and the FCA's October 2025 High Court action for unlawful financial promotions. These new facts support a WARNING band (20–49) — elevated risk with unresolved severe regulatory incidents — rather than CRITICAL. A score of 28 reflects serious material concerns (UK sanctions, FCA enforcement, PoR irregularities, significant hack history) while correctly declining to label a functioning exchange as fraudulent. An outside skeptic can verify: SEC LR-26496 (dismissal), Bloomberg May 26 2026 (UK sanctions), FCA press releases October 2025 (court proceedings), CNBC November 23 2023 (HECO hack), and Cryptoslate October 7 2023 (fund recovery).","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
