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 three security incidents (Nov 2023 CAKE bug, March 2026 Votemarket oracle exploit, May 2026 vsdCRV deployer-key exploit) are all confirmed with figures, dates, and mechanisms matching primary and independent sources closely. The two weakest points are the SDT all-time-high and all-time-low price claims, which do not match the page's own cited CoinGecko source and, in the all-time-low case, are also stale given a new lower low set after the 2026 exploits. Two timeline dates (2022-01-01, 2023-01-01) bear the hallmarks of rounded placeholders rather than sourced exact dates, though the underlying year/quarter is directionally correct.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
