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 disputed_pct of 2.5% falls well within the 0-10% approval band. Ten claims are partially_supported, but none concern the page's core allegations about Madoff's fraud, prosecution, or sentencing; the inaccuracies are limited to peripheral figures (client account count off by ~100, recovery rate understated by ~3 percentage points, Scaramucci's title misdescribed, a verbatim DOJ quote not independently verified verbatim). Two FBI press release URLs returned 403 errors (link rot), but in both cases the underlying facts were independently confirmed by Tier 1 government sources. The one high-priority coverage gap — a deeper structural mapping of Madoff patterns to crypto market risks — is an editorial expansion suggestion, not a factual deficiency warranting denial or revision status.","score_delta":0,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
