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.

Two concrete errors were found: the maximum price quoted for OneCoin's 'educational packages' (225,500 euros) contradicts the page's own cited Wikipedia source, which states 118,000 euros; and the timeline records Mark Scott's sentencing as April 4, 2023, when both the cited Record article and the DOJ/IRS-CI release place it on January 25, 2024 -- a nine-month error sourced from the page's own citation. A third, lower-severity issue is that the June 2022 timeline entry folds in a $250,000 reward increase that actually occurred in May 2023, implying it happened nearly a year earlier than it did. Coverage gaps include other prosecuted associates, broader regulatory history, and the scheme's post-2017 continuation.","score_delta":0,"sequence_num":6,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
