RAILGUN Under Scrutiny Over Money Laundering Concerns
The cryptocurrency privacy protocol RAILGUN has come under scrutiny after users in federal prison in Miami mentioned it as a tool for concealing transactions. The protocol's zero-knowledge cryptography makes it difficult to track wallet addresses, transfer amounts, and types of cryptocurrencies involved in a transaction.
This feature has raised concerns that the service may be used for money laundering and other illicit activities. According to Chainalysis experts, criminals received at least $82 billion in digital assets in 2025, with any services complicating blockchain transaction analysis under close scrutiny from analysts and law enforcement agencies.
The case of Andrew Tate, a blogger currently in custody facing charges including serious crimes and money laundering, has highlighted the growing interest in illicit cryptocurrency operations. Tate promoted a meme token based on Solana, which is often used for speculative purposes rather than practical use.
