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.

was a Web3 gambling platform that raised approximately $33 million from over 10,000 investors through a 'Bridge-to-Earn' campaign in early 2024, promising depositors their ETH would be returnable within 30 days. Instead, the platform converted depositor ETH into its native ZKAS tokens and staked the funds on Lido without user consent, prompting Dutch authorities (FIOD) to arrest founder Elham Nourzai in April 2024 and seize over EUR 11 million in assets. A second suspect linked to the WhiteRock token project was arrested in the UAE in July 2025 and faces extradition to the Netherlands, while partial refunds to affected depositors remained incomplete as of late 2025.","timeline":[{"date":"2024-03-17","event":"ZKasino launches Bridge-to-Earn program, inviting users to deposit ETH with promises of full redemption within 30 days.","source":""},{"date":"2024-03-19","event":"ZKasino announces Series A funding at a $350 million valuation, citing MEXC as a backer.","source":""},{"date":"2024-04-04","event":"ZigZag Exchange publicly accuses ZKasino of fraud and misappropriation of approximately $15 million from ZigZag's treasury.","source":""},{"date":"2024-04-18","event":"ZKasino removes the bridge-back guarantee from its user interface without announcement.","source":""},{"date":"2024-04-20","event":"ZKasino announces conversion of all deposited ETH to vested ZKAS tokens; official Telegram group is shut down.
