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.

Verdict: over-penalized. Page content is treated as accurate; the trust_score band is miscalibrated. Deribit is a 9-year-old legitimate derivatives exchange that was acquired by Coinbase for $2.9 billion in August 2025 — the largest M&A deal in crypto history. Every incident driving its WARNING-band score was suffered by the entity, not caused by it: the November 2022 $28M hack was attributed to North Korea's Lazarus Group (a state-sponsored actor), Deribit covered all losses from its own reserves within 24 hours, no client funds were at risk, and the US government subsequently filed forfeiture complaints against the Lazarus Group for this very theft. The 3AC connection was as a creditor owed ~$80M, not as a co-conspirator — Deribit forced 3AC's liquidation. The exchange obtained a conditional VARA license in April 2024 (the first derivatives exchange to do so) and completed its Dubai migration on January 1, 2025. A score of 47 in the WARNING band implies 'elevated fraud/loss risk or unresolved severe incidents'; all identified incidents are fully resolved and externally attributed. The correct band under the post-policy semantics is VERIFIED (70-100), with a score around 72 reflecting minor deductions for: residual geographic restrictions (US/UK/Canada users excluded), the single unrecovered hack loss, and the historical Panama incorporation strategy. An outside skeptic can verify the Coinbase acquisition via SEC 8-K filings, the VARA license on VARA's public register, and the Lazarus Group attribution via US DOJ forfeiture filings.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
