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.

The principal factual errors are: (1) the Tornado Cash OFAC delisting is dated April 2025 but occurred March 21, 2025 per official Treasury records; (2) timeline[3] incorrectly attributes 10,000 BNB to Tornado Cash when CoinDesk confirms only 2,500 BNB ($686K) went there; (3) the Fifth Circuit ruling is placed in December 2024 but occurred November 26, 2024; and (4) ZachXBT is twice credited with flagging the protocol but no reviewed source supports this — PeckShield is the credited detector in all coverage.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
