Doublezero (2Z) is a blockchain infrastructure protocol focused on building a high-performance network layer for distributed systems. Instead of functioning as a Layer-1 blockchain, Doublezero optimizes the data transport layer by deploying dedicated fiber and hardware to enhance routing efficiency and reduce latency for decentralized applications. The protocol enables scalable, low-latency communication across blockchains, supporting faster DeFi, gaming, and cross-chain use cases.
