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.

Two factual errors were identified: (1) the page states OFAC first designated Lazarus Group on April 3, 2018, when the actual first Lazarus Group entity designation was September 13, 2019 (the 2018 action designated Park Jin Hyok and Chosun Expo individually); and (2) the WazirX timeline entry uses July 1, 2024 rather than the correct July 18, 2024. Three claims are partially supported due to minor overstatements (the Bangladesh Bank '~$1 billion' attempt, the UN Panel '40%' figure presented as a direct Panel finding rather than a member-state estimate relayed by the Panel, and the front company name rendering). No link rot or unverifiable core claims were found.","score_delta":0,"sequence_num":1,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
