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 material errors were found: (1) the FATF grey list removal date is stated as June 2022 but the correct date is June 28, 2024, confirmed by FATF's own publications and CNBC; (2) a timeline entry is dated April 1, 2021 — clearly a data entry error for late April 2021. The page also omits a significant January 2025 legal development in which the organized crime portion of Özer's conviction was overturned on appeal, reducing the effective sentence before his November 2025 death. The Chainalysis figure is consistently cited at $2.52 billion but the page rounds it to $2.6 billion throughout.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
