Binance founder Changpeng “CZ” Zhao has reported to a federal prison in California where he will spend the next four months for failing to implement an adequate know-your-customer (KYC) program at the world's largest cryptocurrency exchange.

Zhao, a Canadian national, pleaded guilty to violating the Bank Secrecy Act (BSA) in November. In April, a federal judge sentenced CZ to four months in prison – a much shorter sentence than the three years federal prosecutors requested but more than other crypto executives like former BitMex CEO Arthur Hayes received for the same crime.
