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.

However, two factual errors appear: Roman Semenov was individually added to OFAC's SDN List on August 23, 2023 (claim_findings[7]), not November 2022 as stated in the Founders section and timeline entry (claim_findings[23]). Additionally, Storm's trial began July 14, 2025, not 'late July' (claim_findings[19]). These are clear departures from Tier 1 Treasury and court sources, and the Semenov date error recurs. The disputed/partially-supported percentage is 17%, placing this in the minor-issues band. No coverage gaps rise to priority-high status.","score_delta":-12,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
