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 main problem is citation: the secondary sources cited for these details (Caproasia, Finance Magnates, InvestmentNews) mostly do not contain them, and the CFTC release does not state the $16M figure. The Dominican Republic relocation rests on a blocked, low-tier source, and the complaint lists Halladay as a Florida resident. The Cloud Token and JJ3B claims are single-source and uncorroborated. The page hedges these allegations appropriately.","reviewer_def_hash":"bc11388ce4bc4deea1b064fea362663ae06e3f4f687f99604769044d6ffba770","score_delta":0,"scored_claims":7,"sequence_num":3,"subject_status":"unknown","subject_status_contradicts_page":false,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
