DoubleZero’s fiber network reduces blockchain latency by half, with mainnet set to launch on October 2nd

DoubleZero Protocol has revealed that its mainnet will go live on October 2nd, 2025, together with the introduction of its native token, 2Z. Supported by a $28 million investment round led by Multicoin Capital and Dragonfly Capital, the initiative seeks to tackle blockchain scalability by building a high-speed fiber network that can lower latency by as much as 50% compared to conventional internet systems DoubleZero Protocol Set for Mainnet Launch in September 2025 [ 1 ]. The mainnet will expand to more than 70 fiber connections worldwide, a significant increase from the 8 links on its testnet, and is designed to enhance Solana’s ecosystem while maintaining compatibility with other distributed platforms DoubleZero Launches Mainnet to Cut Blockchain Latency [ 2 ].

The protocol introduces an “N1” foundational layer, positioning itself as a core infrastructure layer for blockchains rather than a typical Layer 1 or Layer 2. Utilizing advanced fiber optics and hardware such as FPGAs, DoubleZero filters out spam transactions—which make up about 70% of blockchain activity—and streamlines data distribution for validators. This method addresses key inefficiencies between decentralized networks and centralized internet, such as bandwidth limitations and erratic routing A Deep Dive into DoubleZero [ 3 ]. The testnet, which operates in seven major cities globally, has already shown notable improvements in performance, with

The 2Z token, built as a Solana SPL token, is integral to the network’s ecosystem. It is used for collecting user fees and rewarding those who contribute infrastructure, with a tokenomics model that links compensation to real-time network usage. Instead of relying on inflation, 2Z ensures that contributors are paid based on the actual value of bandwidth provided, not on speculative price swings.

DoubleZero’s emphasis on geographic decentralization further boosts the robustness of blockchain networks. The mainnet beta, which began in September, features over 200 validators around the world and aims to increase participation in regions that are typically underrepresented. This strategy supports Solana’s global scaling ambitions, as highlighted by co-founder Anatoly Yakovenko, who pointed to the project’s contribution to achieving near “speed of light” synchronization DoubleZero Launches Mainnet to Cut Blockchain Latency [ 2 ]. The network’s ability to switch to public internet connections during disruptions ensures both reliability and continued performance benefits DoubleZero Launches Mainnet to Cut Blockchain Latency [ 2 ].

The project’s financial backing and collaborations highlight its potential to transform decentralized infrastructure. With key contributors such as Malbec Labs, Jump Crypto, and RockawayX, DoubleZero is working to establish a marketplace for unused dark fiber, tapping into roughly 65% of dormant U.S. fiber resources DoubleZero Foundation Secures $28 Million at $400 … [ 6 ]. Investors like Foundation Capital and Borderless Capital see the network as vital for enabling high-throughput blockchains, especially as Solana pursues the goal of processing one million transactions per second DoubleZero's 'New Internet' for Blockchains Nabs … [ 12 ]. The foundation intends to use the raised capital to expand teams in marketing, developer relations, and business development, speeding up the shift from testnet to public mainnet DoubleZero Foundation Secures $28 Million for … [ 11 ].

DoubleZero’s debut represents a significant move toward solving the physical network limitations that are often neglected in blockchain scaling solutions. By focusing on increasing bandwidth and minimizing latency, the protocol has the potential to improve validator performance, enhance decentralization, and support resource-intensive applications. As the crypto sector continues to innovate in infrastructure, DoubleZero’s blend of physical fiber networks and decentralized governance could set a new benchmark for future distributed systems DoubleZero Launches Mainnet to Cut Blockchain Latency [ 2 ].
