The DoubleZero protocol is an innovative decentralized framework designed to enhance the performance of distributed systems by optimizing data flow and increasing bandwidth to reduce latency. By integrating fiber optic links to build a synchronized network, it effectively filters spam, boosts bandwidth, lowers latency, and eliminates instability in communication. This article explores DoubleZero's network architecture, its operational mechanisms, and how it offers significant performance improvements for blockchain systems and other distributed networks, while also discussing its potential as a new economic model in the bandwidth and communication sectors.
