Tornado Cash Crypto Mixer Faces Legal Woes!

Tornado Cash, a decentralized crypto mixer on Ethereum, enhances transaction privacy using zero-knowledge proofs, allowing anonymous crypto transfers without revealing wallet history. The U.S. Treasury sanctioned it in 2022, accusing it of laundering billions, including $455M linked to North Korea's Lazarus Group, posing national security threats. In 2025, sanctions were lifted, sparking debates on balancing crypto privacy and security. The saga highlights challenges in regulating decentralized finance while maintaining financial privacy.
