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.

Verdict: over-penalized. Page content is treated as accurate; the trust_score band is miscalibrated. Upbit is South Korea's dominant, licensed cryptocurrency exchange operated by Dunamu. All major loss events on the page — the 2019 $50M ETH hack and the 2025 $36M Solana hack — were externally inflicted, with one officially attributed to North Korea's state-sponsored Lazarus Group, and both were fully reimbursed by the exchange using corporate reserves. The 2018 executive fraud indictment ended in a 2021 court acquittal for lack of evidence. The 2025 FIU $25M fine and business suspension, the most recent regulatory negative, was overturned by the Seoul Administrative Court, which found the underlying compliance standards were insufficiently specified — further undermining its use as a persistent negative signal. The exchange continues to operate under full regulatory registration, holds ISMS and ISO certifications, commands 70-80% domestic market share, and as of mid-2026 has attracted an institutional Hana Bank stake of $670M. None of the scored incidents meet the definition of entity-originated fraud. The correct classification under the band policy is CAUTIONARY (50-69): legitimate operator with material caveats (repeated hot-wallet security failures, ongoing AML scrutiny, market concentration concerns). A score of 58 reflects the genuine security and compliance concerns without mislabeling a victim of state-sponsored hacking as a fraud risk.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
