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.

Core regulatory facts — the UK FCDO designation, the FCA civil enforcement, the TRM Labs on-chain flow figures, the SEC settlement, the 2023 security incidents, and the founding history — are all confirmed by primary or high-tier secondary sources. The primary factual problem is a disputed claim about '2.9 billion WLFI tokens' frozen, which is not supported by the cited source or any other source identified. Secondary issues include a dropped qualifier in an Elliptic quote ('suspected of providing services' rendered as 'provided services') and a minor overstatement of Chainalysis's characterization of HTX as 'primary' trading hub. The page contains no link rot among the sources verified.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
