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 page incorrectly states Ethereum was 'not explicitly named' in the March 17, 2026 SEC/CFTC digital commodity release — multiple credible legal sources confirm ETH was explicitly listed among the 16 named commodities; (2) the DeFi TVL figure of '$99 billion' appears to reflect a late-2025 peak rather than the May 2026 state, with current data indicating a decline to approximately $45-57 billion. The DAO hard fork block number (192,000 vs. the correct 1,920,000) also appears to be a transcription error. All cited sources that could be checked were accessible and broadly support the claims attributed to them.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
