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.

One clear factual error was identified: the criminal co-defendants are misidentified — the page names 'former Chief Product Officer and former Chief Financial Officer' when the actual co-defendants were Oliver Bellenhaus (former head of the Dubai subsidiary) and Stephan von Erffa (chief accountant/deputy CFO). A significant currency issue also exists: the page presents the September 2024 pari passu ruling on shareholder claims as current, but this was reversed by the Federal Court of Justice in November 2025, fundamentally changing the insolvency recovery picture for ~50,000 shareholders. Minor imprecisions include the FT investigation start date (tip in 2014, not April 2015) and the characterization of six Bulgarians being 'convicted' when three pleaded guilty and three were convicted at trial.","score_delta":0,"sequence_num":1,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
