A co-founder of a major crypto mixing service has been sentenced to five years in prison for his role in laundering millions through anonymous blockchain transactions. Prosecutors said the platform was used by cybercriminals to conceal the origins of illicit funds tied to ransomware, hacking, and darknet markets. The court ruled that the service knowingly enabled money laundering by obscuring transaction trails, violating financial transparency laws. The defendant’s conviction follows global crackdowns on crypto privacy tools accused of aiding criminal activity. Authorities say the case sets a strong precedent for stricter regulation and accountability in crypto transaction anonymization.
