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. KuCoin is a real, operating cryptocurrency exchange with 41M+ registered users, proof-of-reserves audits, and SOC2/ISO27001 certifications — not a scam or Ponzi. The incidents driving its CRITICAL score are (1) a $275-285M hack in September 2020 attributed by Chainalysis to North Korea's Lazarus Group (an external state-sponsored actor, suffered by KuCoin), (2) a guilty plea to unlicensed money transmission — an AML/BSA compliance violation — resulting in $297.4M in penalties, (3) a C$19.6M FINTRAC fine in Canada, (4) a permanent CFTC bar from the US market in March 2026, (5) an Austrian FMA ban on new business in February 2026, and (6) ZachXBT allegations in April-May 2026 that KuCoin allowed $13M+ in stolen funds to pass through its deposit addresses while ignoring law enforcement. None of these constitute KuCoin itself running a fraud, exit scam, or Ponzi. The entity has serious and documented compliance failures (deliberately avoiding KYC to attract global users, failing to file SARs) and credible recent allegations of non-cooperation with crime victims, which together justify WARNING band. A score of 28 reflects: severe AML enforcement history across three jurisdictions, ongoing ZachXBT allegations, multi-year US market ban, but also the fact the entity is a legitimate operating exchange that repaid hack victims, maintains proof-of-reserves, and was not convicted of defrauding customers.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
