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 specific errors were identified: the timeline dates the Wembley Stadium event to July 2016 when it occurred June 11, 2016, and states the internal marketplace first closed in January 2016 when it actually closed March 1, 2016. Four claims were partially supported due to minor imprecisions (the Vietnam regulatory action, the Konstantin Ignatov arrest date precision, the Wembley section text vs. timeline, and the raid attribution to Europol alone). One claim — that company insiders called tokens 'fake coins' — could not be independently verified in primary sources. No link rot was detected on the DOJ, FBI, Wikipedia, or ICIJ sources that were directly checked. The trust score as extremely low (fraud, no real blockchain, $4B+ scheme, multiple convictions, fugitive founder) is appropriately calibrated.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
