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.

However, the page's account of what happened afterward is stale and, in places, wrong: it states the exchange never resumed operations when it in fact reopened for trading in July 2018 (claim_findings[3], [37], [45]); it says no compensation announcement was made when Coinrail announced a compensation plan in June 2018 and a Seoul court ordered it to pay hacking victims in 2021 (claim_findings[39]); and it frames the case as unattributed when a suspect was arrested and indicted in France in January 2025 (claim_findings[9], [31], marked 'stale' rather than 'disputed' but pointing the same direction). Recovered ETH from a 2021 Korean police operation is also omitted (claim_findings[30]). Using the reviewer's own formula -- (disputed + unverifiable) / total -- the disputed share is 5/49, or 10.2%, which sits just over the 10% line separating a clean approval from a revision requirement. Combined with two high-priority coverage gaps both pointing at the same missing post-2018 timeline, this page needs its aftermath section brought current rather than a pass or a takedown.","score_delta":-15,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
