Alexey Pertsev, the developer of the Tornado Cash protocol, has been denied release by a Dutch court on July 12.
Convicted of money laundering in May and sentenced to over five years in prison, Pertsev remains in custody as he plans to appeal.
The Hertogenbosch Court of Appeal rejected his release, despite his lawyers arguing he was not a flight risk and needed internet access for his appeal.
The court maintained its stance due to the severity of the case, where Pertsev and his colleagues were found guilty of facilitating the laundering of $2.2 billion in stolen cryptocurrency.
This case, following US Treasury sanctions on Tornado Cash, has raised concerns about the liability of developers of privacy-focused open-source software. It highlights the tension between blockchain innovation and regulatory compliance.
Further legal challenges continue, with developer Roman Storm set to face trial in the US on similar charges in September.
The U.S. Department of Justice has sentenced Dwayne Golden, 57, of Pennsylvania to 97 months in prison for orchestrating a fraudulent crypto investment scheme that stole over $40 million from investors.
The first half of 2025 has become the most damaging six-month period in crypto history, with over $2.1 billion stolen across 75+ separate incidents, according to new data.
A new breed of cyber-attack is sweeping through crypto media, exploiting site pop-ups and wallet-connect prompts instead of smart-contract bugs.
CoinMarketCap, one of the most widely used crypto data tracking platforms, is reportedly facing a front-end security breach, with multiple users encountering a suspicious prompt to verify their wallets.
