DoubleZero is a new internet optimized for distributed systems, like blockchain. Backed by Multicoin, Dragonfly, and other leading VCs, it’s a global physical fiber network leveraging existing subsea and terrestrial links. Now, its native token, 2Z, is being offered to validators — the first token sale open to U.S. accredited investors since 2019.
The DoubleZero (2Z) sale is open to core builders—specifically, it’s designed for validators across Solana, Aptos, Avalanche, Celestia, and Sui. Here’s how it works:
The bottleneck for blockchain today isn't compute—it's communication. Network bandwidth and latency constrain blockchain performance, validator efficiency, and limit scalability. Yet today's internet has a fundamental flaw: it was built for resilience, not performance.
DoubleZero is building a new internet optimized for distributed systems, with the goal of being fully permissionless, capable of filtering spam, and routing traffic with efficiency not possible on the public internet. Imagine blockchains, validators, RPCs, MEV systems, and many more components being able to communicate at speeds previously difficult to reach, unlocking a new era of blockchain performance, scalability, and decentralized applications. Powered by specialized FPGA hardware and dedicated fiber links, DoubleZero seeks to revolutionize blockchain infrastructure and the way data moves between validators across the globe. This is the missing foundation beneath modern distributed systems—and as a validator operator you can be part of it.
DoubleZero aims to remove the constraints the public internet has imposed on protocol designers and validator operators. We aim to accelerate decentralised and distributed systems by a decade, unlocking new use cases for blockchain systems.
Built on principles of permissionless networks and high-performance infrastructure, DoubleZero’s core contributors include Malbec Labs and Jump Crypto, networking experts, blockchain infrastructure specialists, and performance optimization engineers who all share the common goal of establishing the most efficient network protocol for distributed systems communication.

The DoubleZero (2Z) token isn’t being sold through an ordinary sale. It is being offered specifically to eligible validators across the Solana, Aptos, Avalanche, Celestia, and Sui ecosystems through a multi-step process.
DoubleZero is a physical fiber network spanning the globe - using existing subsea and terrestrial fiber links contributed by a diverse set of network contributors. This physical fiber layer provides an alternative pathway for distributed systems to communicate over, one that is far more stable and predictable than the public internet.
Validators on high-performance blockchains such as Solana can be inundated with a flood of inbound transactions when building a block, reducing block-building efficiency and reducing rewards. One the validator has produced a block, it has to transmit that block out to thousands of other validators so consensus can be reached before the network can advance – and DoubleZero provides a faster, more efficient base layer for that communication.
DoubleZero enables validators to operate at maximum efficiency without massive infrastructure investments—a paradigm shift for blockchain networks where communication, not computation, has become the real bottleneck.
The 2Z token is designed to underpin the utility, efficiency, and security of the DoubleZero protocol by aligning incentives between users, contributors, and community members. Once the protocol is fully operational, the 2Z token is expected to serve the following key functions:
The below diagram shows the general flow for the 2Z token. Please see a longer description of these core concepts at: https://economics.doublezero.xyz/overview
DoubleZero creates a new internet optimized for distributed systems. Its architecture combines specialized filtering hardware at network edges with dedicated fiber connections between validators, forming a high-performance mesh network. The Two-Ring Architecture separates functions: an outer ring filters spam and verifies signatures using FPGA devices, while an inner ring provides low-latency paths for consensus traffic. DZXs (DoubleZero Exchange points) serve as critical interconnection hubs where contributed fiber links converge, creating a global network that dramatically increases bandwidth and reduces latency for blockchain systems worldwide.
Leveraging dedicated fiber infrastructure and specialized hardware like FPGAs, DoubleZero enables high-bandwidth, low-latency communication for blockchain networks without relying on the public internet's congested pathways.
Introducing the DoubleZero Roadmap: The highway to accelerating high-performance distributed systems
After just 90 days post launch and 30 days of testnet operations, DoubleZero has seen remarkable interest — with 2,298+ applications to our permissioned testnet pushing capacity across 7 global data centers to 86%.
Private Testnet – Q1 2025 - Q2 2025
Our private testnet has deployed across 7 strategic global locations, giving early builders exclusive access to this new network infrastructure. During this phase, we've onboarded nearly 35 teams spanning both Solana testnet and mainnet validator environments, all exploring what's possible beyond public internet constraints.
Public Testnet – Q2 2025
The network expands in two months — DoubleZero's public testnet goes live. Validators will run nodes permissionlessly, while qualified contributors can provide bandwidth to strengthen the growing network.
Each phase will methodically introduce new capabilities as we advance toward our full mainnet launch.
Mainnet and TGE – Q3 2025
The moment arrives. DoubleZero's mainnet launch and TGE marks our full deployment. Users will experience the network's full potential, while node operators and contributors begin earning rewards for securing and expanding this new infrastructure.
Multitenancy Expansion — Q1 2026
After proving our technology on Solana, DoubleZero will expand to support multiple chains and networks. We're reimagining infrastructure for every distributed system, aiming to deliver optimal performance at every step of the way.
