DoubleZero builds a private fiber network for high-performance blockchains

Blockchains like to talk about decentralization. Most of them still send their data over the same public internet you use to stream cooking videos. DoubleZero wants to change that. The project is building a dedicated network for the high-performance distributed systems that crypto depends on, and it has already signed up a large share of Solana. Approximately 59% of Solana mainnet stake weight is connected to DoubleZero as of mid-2026. For a network whose mainnet-beta went live less than a year earlier, that is a fast climb. What DoubleZero actually does DoubleZero stitches together independently contributed private fiber-optic links into a transport layer designed specifically for distributed systems. The model is permissionless. Anyone with underused private fiber can plug it into the network. Contributors are not paid simply for showing up. Rewards are tied to the performance gains their links actually deliver. The network launched its mainnet-beta on October 2, 2025. The native 2Z token, an SPL token on Solana, debuted publicly the same day. According to the project’s metrics, the network now carries an aggregate capacity of around 10 terabits per second.
