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.

The single disputed claim is claim_findings[13]: the FCA legal proceedings date is listed as February 2024 when the FCA filed High Court proceedings in October 2025 and published its press release in February 2026 — a significant date error in the timeline but not a core allegation about Sun's conduct. A modest score penalty is applied for this error and for the structural completeness gap: all ten page sections have empty content fields, meaning the page consists only of a summary and timeline with no section-level analysis. This gap is flagged for expansion but does not dispute any verified fact.","score_delta":-5,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
