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.

However, three issues warrant revision: claim_findings[11] states Earn investors received full recovery 'by late 2025' when multiple Tier 2 sources confirm the recovery was announced in May 2024 — a 16-month factual error in a high-severity section; claim_findings[32] characterizes the Winklevoss Capital Bitcoin payment as '2.5x the prevailing Bitcoin market price' when the 2.5x premium actually refers to the price per GEMI share versus its trading price, not an above-market Bitcoin valuation; and a high-priority coverage gap exists for the June 2024 New York Attorney General $50 million settlement — a significant enforcement action omitted entirely from the regulatory section. These corrections are factual and bounded; the page's regulatory timeline, IPO financials, and enforcement narrative are otherwise well-sourced.","score_delta":-8,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
