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 primary findings warranting correction are: (1) the ANIFTY 'acquired' characterization conflicts with evidence that the service shut down in June 2025; (2) the 2026 round is described as 'led by SBI Ven Capital' but the primary PR Newswire source does not name a lead investor; (3) the Unified Smart Contracts timeline entry is dated 2024-01-01 but the actual announcement was December 20-21, 2023; and (4) the 'patented auto-routing' claim is repeated without a verifiable patent number. Currency denomination (USD vs CAD) is ambiguous across cited sources but not materially inaccurate.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
