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.

However, claim_findings[15] identifies a material factual error: the page states C$53 million was tied up in a CIBC dispute, whereas all credible sources (CBC Tier 1, Norton Rose Tier 2, Wikipedia Tier 2) consistently report C$25-28 million. This figure requires correction. Four claims are only partially supported due to minor details (age of Crohn's diagnosis, Shadowcrew arrest count of 28 vs. 19 confirmed arrests, EY recovery understated vs. final distribution), but these do not rise to the level of clear errors. At 15% disputed weight with high reviewer confidence (0.82) and strong Tier 1 source support for all major allegations, the page warrants revision rather than denial or further investigation.","score_delta":-8,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
