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
- 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. - 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.
- 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.

All core claims — SEC enforcement action, civil judgment amounts, DOJ criminal prosecution timeline, Chen's sentence, his death in custody, and the scheme's mechanics — are confirmed by primary government sources (DOJ press releases) and multiple reputable secondary sources. The most notable finding is a one-day date discrepancy on Chen's sentencing: the page consistently states January 10, 2021, but multiple independent sources including contemporaneous news reporting cite January 11, 2021. Five claims are partially supported due to minor characterization issues: the four-country mine location list (SEC complaint named only two countries; four countries appears in DOJ criminal proceedings), the $15 billion vs $5 billion backing claim figure (different promotional phases cited different numbers), the class action filing date (October 5 vs the CoinDesk article date of October 8), and the plea agreement framing (agreement announced February 2020, formal plea may have been June 2020). No claims are disputed, unverifiable, or link-rotted; the primary government URLs return 403 errors to automated fetchers but the URLs are structurally valid and all content is corroborated by accessible secondary sources.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
