DoubleZero’s Fiber Network Cuts Blockchain Latency 50%, Launching October 2nd Mainnet

DoubleZero Protocol has announced the launch of its mainnet on October 2nd, 2025, alongside the deployment of its native token, 2Z. The project, backed by a $28 million funding round co-led by Multicoin Capital and Dragonfly Capital, aims to address blockchain scalability challenges through a high-performance fiber network designed to reduce latency by up to 50% compared to traditional internet infrastructure DoubleZero Protocol Set for Mainnet Launch in September 2025^[1]. The mainnet will feature over 70 global fiber links, significantly expanding from its testnet’s 8 links, and is expected to support Solana’s ecosystem while remaining compatible with other distributed systems DoubleZero Launches Mainnet to Cut Blockchain Latency^[2].

The protocol’s architecture introduces an “N1” base layer, positioning it as a foundational infrastructure layer for blockchains rather than a traditional Layer 1 or 2 solution. By leveraging specialized fiber optics and hardware like FPGAs, DoubleZero filters spam transactions (accounting for ~70% of blockchain traffic) and optimizes data propagation for validators. This approach addresses critical mismatches between decentralized systems and centralized internet infrastructure, including bandwidth constraints and unpredictable routing A Deep Dive into DoubleZero^[3]. The network’s testnet, operational in seven global cities, has already demonstrated measurable performance gains, with Solana validators participating in early trials DoubleZero Foundation Secures $28 Million for …^[11].

The 2Z token, a Solana SPL token, plays a central role in the ecosystem. It is used to collect user fees and distribute rewards to infrastructure contributors, aligning incentives through a tokenomic model that ties payments to real-time demand. Unlike inflationary models, 2Z ensures contributors are compensated for bandwidth utility rather than speculative volatility. The token sale, exclusive to validators from Solana, Sui, Aptos, Avalanche, and Celestia, allocated 1.5% of the total supply in its initial round, with U.S. accredited investors participating for the first time since 2019 DoubleZero's Funding Rounds & List of Investors - Tracxn^[9].

DoubleZero’s strategic focus on geographic decentralization further strengthens blockchain resilience. The mainnet beta, launched in September, includes over 200 global validators and aims to expand participation in underrepresented regions. This approach aligns with Solana’s vision of global scalability, as noted by co-founder Anatoly Yakovenko, who emphasized the project’s role in advancing the “speed of light” synchronization goal DoubleZero Launches Mainnet to Cut Blockchain Latency^[2].

The project’s funding and partnerships underscore its potential to redefine decentralized infrastructure. With core contributors like Malbec Labs, Jump Crypto, and RockawayX, DoubleZero aims to create a marketplace for underutilized dark fiber, leveraging ~65% of unused U.S. fiber capacity DoubleZero Foundation Secures $28 Million at $400 …^[6]. Investors, including Foundation Capital and Borderless Capital, view the network as a critical enabler for high-performance blockchains, particularly Solana’s ambition to process one million transactions per second DoubleZero's 'New Internet' for Blockchains Nabs …^[12].

DoubleZero’s launch marks a pivotal step in addressing the physical network layer, often overlooked in blockchain scalability solutions. By prioritizing bandwidth and latency reduction, the protocol could enhance validator efficiency, decentralization, and support for demanding applications. As the crypto industry continues to seek infrastructure innovations, DoubleZero’s approach—combining physical fiber networks with decentralized governance—positions it as a potential standard for next-generation distributed systems DoubleZero Launches Mainnet to Cut Blockchain Latency^[2].
