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 page correctly distinguishes attestation from audit, a distinction other pages reportedly conflate. The main weaknesses found are: one disputed launch date (page says Feb 9, 2026; two independent primary sources say Feb 10, 2026), an unverified 'top six regulated stablecoins' ranking sourced only to the issuer's own PR, a material omission of Anchorage Digital Bank's 2022-2025 OCC consent order for BSA/AML deficiencies from the fraud/enforcement section, incomplete exchange-listing coverage (a Kraken listing was found independently but not mentioned), and a couple of claims (the on-chain contract address, ATH/ATL figures) that could not be independently verified with the tools available.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
