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 exchange has experienced two significant security events: a November 2023 liquidity crisis triggered by a $26 million hack of its primary market maker Kronos Research, and a July 2025 $14 million breach of nine user accounts attributed to a North Korean state-sponsored group (UNC4899/Lazarus) via phishing of a developer. Both incidents resulted in user compensation from company reserves, though the pattern of security failures and structural dependency on Kronos Research represent elevated counterparty and operational risk.","timeline":[{"date":"2018-01-01","event":"Kronos Research founded in Taiwan as a quantitative high-frequency trading firm by Jack Tan and Mark Pimentel.","source":""},{"date":"2019-01-01","event":"WOO Network founded by Kronos Research co-founders Jack Tan and Mark Pimentel, incubated by Kronos Research.","source":""},{"date":"2021-08-01","event":"WOO X launches publicly as a centralized exchange, billing itself as the first crypto exchange to use a Payment for Order Flow model.","source":""},{"date":"2022-09-08","event":"WOO Network receives AML registration approval from Taiwan's Financial Supervisory Commission, the only foreign applicant among 24 approved platforms.","source":""},{"date":"2023-08-01","event":"Two Kronos Research engineers are convicted by a Taipei court of tampering with trading algorithms over unpaid bonuses, causing approximately $1.4 million in losses.","source":""},{"date":"2023-11-18","event":"Kronos Research's exchange API keys are compromised by an external attacker; approximately $26 million is stolen.
