Railgun, a crypto privacy protocol gaining recognition as a key Tornado Cash alternative, has recently refuted claims that it's being used by North Korea and other entities under U.S. sanctions to launder cryptocurrency.

The protocol's developers pointed out that their use of zero-knowledge (ZK) technology inherently prevents such misuse, emphasising the lack of evidence backing these accusations.

This clarification comes at a time when Railgun's transaction volume is approaching the $1 billion milestone, a surge partly attributed to support from Ethereum co-founder Vitalik Buterin, who publicly endorsed the platform's privacy features.

Founded in January 2021, Railgun leverages ZK cryptography to protect users' privacy, allowing them to engage with decentralised apps (DApps) on Ethereum and other supported blockchains discreetly.

By masking wallet balances, transaction history, and details, it ensures that users can interact with the blockchain ecosystem without exposing their financial activities.

This technology underscores Railgun's commitment to privacy and security in the rapidly evolving crypto landscape.
