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.

However, the review found one clear factual error (Angel Drainer's shutdown is dated July 2024 in independent reporting, not March 2024 as stated), one clearly unsupported/misattributed capability claim (the WalletGuard/Pocket Universe bypass, attributed to Blockaid research that does not make this claim and which independent reporting instead attributes to Angel Drainer), a mischaracterized causal claim about why drainer losses fell 83% in 2025, and a conflation of a broader on-chain-exploit loss statistic with drainer-specific theft trends. Several other claims are the page's own reasonable but unlabeled inferences rather than sourced fact.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
