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.

But the review also flagged, at high priority, that the page itself contains no actual written content -- all seven sections are empty and cite no supporting sources (coverage_gaps[0]) -- and that it omits a materially relevant fact from a source it lists: Hyperdrive's contracts had passed multiple audits before the exploit that later drained the protocol, and the page never says so (coverage_gaps[1]). A page can have a perfect factual record and still fail to inform readers of the most decision-relevant thing its own cited source contains. That gap, not any false statement, is why this page does not clear a clean approval.","score_delta":-10,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
