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.

Four claims are partially supported: Jump Crypto is incorrectly listed as a Series A investor (it participated in the 2022 Coral round only); the FTX EU acquisition date framing understates that the underlying deal closed in June 2024; the Backpack EU launch is dated 'mid-2025' when it actually launched September 8, 2025; and the 'only regulated perpetual futures provider in Europe' claim was contradicted by Ferrante himself citing Kraken as a co-provider. The BP token ATH figure of '$0.45' is consistent with CoinGecko data but disputed by other aggregators. No claims were directly contradicted by a more credible source, and no link rot was detected among checked URLs.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
