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.

Key claims about founding history, the $28M hack, balance-sheet recovery, VARA licensing, and the Coinbase acquisition are confirmed by credible primary and secondary sources. Two claims are partially supported: the summary omits Sebastian Smyczinski as a third co-founder, and the timeline overstates the April 2024 VARA approval as a 'full market product derivatives license' when it was explicitly conditional and non-operational. One cited source (CoinTelegraph article about 3AC exposure) returned a 404. A structural gap exists in that all five page sections have empty content and headings in the review input, limiting assessment of the full written page.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
