The Lightning Network is a second-layer protocol built on Bitcoin that enables near-instant, low-cost transactions. By utilizing off-chain payment channels, multi-signature wallets, and advanced cryptography like Hashed Timelock Contracts, it overcomes Bitcoin’s scalability and congestion challenges. This network allows seamless micropayments, cross-border transfers, and real-time transactions while maintaining security and decentralization. Widely adopted by exchanges, merchants, and fintech platforms, the Lightning Network is transforming Bitcoin into a practical, efficient payment system for global commerce and everyday use.
