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
- 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. - 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.
- 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.

All six claim_findings (indices 0-5) are supported, and disputed_pct is 0%. The review finds Deribit is a 9-year-old legitimate derivatives exchange acquired by Coinbase for $2.9 billion in August 2025 (claim_findings[0]). Every incident driving the current WARNING-band score of 47 was suffered by the entity: the November 2022 $28M hack was attributed by US government forfeiture filings to North Korea's Lazarus Group, all losses were covered from company reserves within 24 hours (claim_findings[1]); the 3AC exposure was as a creditor owed ~$80M, not a co-conspirator (claim_findings[2]); and Deribit obtained a conditional VARA license in April 2024 and completed its Dubai migration on January 1, 2025 (claim_findings[3]). The page's own content confirms the hack was fully resolved (claim_findings[4]) and the Panama relocation was a documented regulatory response, not a fraud-enabling strategy (claim_findings[5]). A score of 47 in the WARNING band implies unresolved severe incidents or elevated fraud risk — neither condition holds. The page content is accurate and stands as published. The appropriate band is VERIFIED (70-100), and a score of 72 reflects reasonable minor deductions for geographic restrictions, the single unrecovered hack loss, and the historical Panama incorporation. A +25 score_modifier_delta moves the score from 47 to 72.","score_delta":25,"sequence_num":5,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
