The vision of peer-to-peer electronic cash represents a fundamental shift in how we think about digital currency and financial transactions. Bitcoin introduced this groundbreaking concept, showcasing how decentralized networks could enable direct value transfer without intermediaries. Litecoin subsequently refined and executed this vision, demonstrating the practical viability of blockchain-based P2P transactions at scale. Both projects exemplify the core principle: empowering users with control over their own digital assets while maintaining transaction security and transparency through distributed ledger technology.
