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.

All core allegations (Fusaka upgrade date and fee reduction, the December 2025 $50M theft sequence, the January 2026 $12.4M OTC incident, Blockaid's aggregated volume statistics, and the Tsuchiya et al. academic dataset) are confirmed by Tier 1 or consistent Tier 2 sources. The five partially-supported findings involve minor rounding differences, a six-day publication date discrepancy (claim_findings[21]), a characterization of the May 2024 WBTC recovery as 'partial' when sources indicate near-complete return (claim_findings[22]), and a $185K single-transaction advertisement verified only through Blockaid's own blog (claim_findings[3]). The one unverifiable claim (claim_findings[10], specific daily dust transaction counts) is a secondary supporting metric, not a core allegation. No Tier 1 source disputes any claim. One high-priority coverage gap — absence of on-chain wallet cluster analysis for campaign operators — is noted for future expansion but does not impair the page's factual integrity.","score_delta":0,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
