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.

The most significant problems found: the On-Chain Reserve Concerns section misattributes a wallet-balance analysis to Nansen when independent reporting consistently attributes it to Arkham, and gives a $69 million post-announcement balance that several independent outlets report as $71 million (this same error is repeated in the timeline); the Industry Context section misattributes an 'over 30 crypto projects folded' figure to CoinDesk, when CoinDesk's own reported 2026 figure is over 100 and the '30' figure traces to a different analyst tracker; the claim that BitMart 'lost' FCA authorization in the UK as of October 2023 overstates what is actually an unauthorized-firm designation with no confirmed prior-authorization status; a 2025 data-breach timeline entry conflates two separate forum posts (exploit listing vs. database leak) under a single incorrect date; and the regulatory section's narrow true statement about no SEC/CFTC action omits a confirmed 2022 FTC investigation. The page is also noticeably stale on the fast-moving reserve story: independent reporting shows continued wallet depletion past the page's July 27 snapshot and a public denial from founder Sheldon Xia, neither reflected here.
