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 review identified one disputed claim (claim_findings[10]): the page states BFX tokens 'opened trading at roughly $0.30,' but contemporaneous CoinDesk reporting places the opening price at $0.10, rising to $0.40 intraday — the page overstates the initial trading price and mischaracterizes early market confidence in BFX redemption. Two additional claims are partially supported: the page implies Morgan was sentenced on November 14 when she was sentenced on November 18 (claim_findings[19]), and the 'under a minute' drain timing comes solely from a non-public Ledger Labs report and cannot be independently verified (claim_findings[7]). A high-priority coverage gap flags that the Bitcoin transfer status section is materially incomplete — as of April 2026 only 8 BTC of the ~94,000 BTC owed had been moved, and the page's 'mid-2026' hedge does not reflect this granular picture. These are correctable factual errors in an otherwise well-sourced investigation.","score_delta":-7,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
