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

  1. 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.
  2. 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.
  3. 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 company was registered in California and Nevada and listed business addresses in Los Angeles and Las Vegas. Investors were charged a minimum of $3,200 per 'mining rig' contract and were promised guaranteed daily returns on their investment across multiple cryptocurrencies. Prosecutors and investigators allege the business functioned as a hybrid pyramid and Ponzi scheme: investors who recruited new participants received referral commissions of approximately $200 per recruit, and the scheme was structured across seven investment tiers, with higher returns promised for larger capital commitments. South Korean prosecutors allege that of the approximately 270 billion won raised, only 75 billion won (approximately $69.6 million USD) was spent on actual mining equipment, and that the generated mining output was insufficient to cover the promised investor returns from the outset. The remainder of investor funds was allegedly diverted to management's personal use, used to reward top recruiters with luxury goods including Mercedes-Benz automobiles, Rolex watches, and gold necklaces, and approximately 100 billion won (approximately $92.8 million USD) is suspected to have been transferred to offshore bank accounts. An investigation by Korean authorities further alleged that MiningMax developed and deployed software designed to simulate cryptocurrency mining activity, deceiving investors into believing returns were being generated when no actual mining was occurring.","heading":"Scheme Structure","severity":"critical","sources":[{"credibility":2,"name":"Prosecutors File Charges in Alleged $250 Million Crypto Mining Fraud — CoinDesk","type":"news_article","url":"https://www.coindesk.com/markets/2017/12/21/prosecutors-file-charges-in-alleged-250-million-crypto-mining-fraud"},{"credibility":2,"name":"Prosecutors Bust Multimillion Dollar Cryptocurrency Scam — The Korea Herald","type":"news_article","url":"https://www.koreaherald.com/article/1536590"},{"credibility":2,"name":"Multimillion Dollar Cryptocurrency Scam By Mining Max Busted In South Korea — IBTimes","type":"news_article","url":"https://www.ibtimes.com/multimillion-dollar-cryptocurrency-scam-mining-max-busted-south-korea-2630744"},{"credibility":3,"name":"Mining Max $250 Million Ponzi Scheme Shut Down, Arrests in Korea — BehindMLM","type":"news_article","url":"https://behindmlm.com/companies/mining-max-250-million-ponzi-scheme-shut-down-arrests-in-korea/"}]},{"content":"South Korean prosecutors estimated total investor losses at approximately 270 billion Korean won, equivalent to roughly $250 million USD at 2017 exchange rates.
