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 most significant finding is a misattribution: the widely-quoted 'vindication' statement about the pardon is attributed to Hayes but was actually made by co-founder Benjamin Delo. Secondary issues include a date error in the CFTC co-founder penalty timeline entry (May 5, 2022 vs. August 10, 2022), a misquote of Hayes' ZachXBT response ('willing buyer' vs. 'willing seller'), the Arkham report date being described as December 2025 when the relevant update was February 2026, and a section heading that implies Maelstrom's own fund underperformed when Vaidya was criticising a third-party fund. The WLD post-note price rise figure (88%) could not be confirmed; available sources report approximately 62%.
