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 factual error—claiming Alameda was co-founded 'alongside Caroline Ellison' when the actual co-founder was Tara Mac Aulay—appears twice (claim_findings[4] and [23]) but does not alter the fraud narrative. A stale claim about SBF's pending motions (claim_findings[21]) requires updating: the new trial motion was denied April 2026; only the Second Circuit appeal remains active. Minor timeline discrepancies (Series C date, Ellison release date) and an understatement of recovered assets ($15B vs. $16.5B) are correctable without material impact. High-priority coverage gaps in on-chain forensics and third-party litigation suggest expansion opportunities, not denial.","score_delta":-8,"sequence_num":5,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
