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 single material factual error is the assertion that Dr. Chengdiao Fan holds a PhD in Computer Science — her PhD is in Anthropological Sciences per her own official biography and multiple corroborating sources. Minor issues include an imprecise ATH date (February 26-27, not February 28), an overstated causal link between the Bybit CEO controversy and the 60% price drop (the ATH was reached after Zhou's comments), and four CoinPedia/Bitget source URLs that returned 403/410 errors and could not be directly verified at review time. The page's framing of the '60-100 million users' claim spans two different time periods and metrics without noting this distinction.","score_delta":0,"sequence_num":1,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
