DoubleZero Mainnet-Alpha Beats Public Internet—Get Ready for the Powerful Mainnet-Beta Launch on October 2

Source: DoubleZero Mainnet-Alpha Performance and What to Expect at Mainnet-Beta
DoubleZero has been steadily advancing its dedicated global network for Solana validators, moving from its limited-access Mainnet-Alpha phase toward a full public launch with Mainnet-Beta on October 2, 2025. Here's a clear look at the current network status and what to expect next.
What is Mainnet-Alpha?
Started on September 15, Mainnet-Alpha is a restricted live network where validators are integrated in small groups (cohorts) to test the system under real-world conditions. This phased rollout helps:
- Collect detailed network data
- Verify that recent improvements work smoothly beyond testnet
- Incorporate validator feedback
- Prepare for a reliable and high-performance public launch
Mainnet-Alpha combines infrastructure from various independent WAN providers, ensuring geographic diversity and strong network resilience.
Mainnet-Alpha Performance Snapshot (Epoch 24)
- 48 active high-performance WAN links outperform regular public internet connectivity.
- 77% of links and 82% of tested city-to-city routes show better latency than public internet alternatives.
- Notable improvements are seen on long-haul routes like São Paulo, Frankfurt–Warsaw, and Dallas–Washington.
However, some routes like Chicago–New York and inbound Singapore connections currently lag behind public internet and are priority targets for further optimizations ahead of Mainnet-Beta.
Expanding Global Reach With City-to-City Routing
Mainnet-Alpha now connects 20 major cities worldwide, creating 210 evaluated city pairs. In epoch 24:
- About 82% of routes delivered lower latency than public internet routes.
- Strongest gains appear on long-distance corridors, with Mumbai frequently achieving significant reductions.
- Key hubs in Europe and North America also demonstrate consistent performance advantages.
This lays a robust foundation for an ultra-low-latency backbone that supports Solana validators globally.
From Testnet to Mainnet-Beta: Growth & Resiliency
Since March 2025, the testnet phase validated the network over 6 months by:
- Deploying 9 DoubleZero Devices (DZDs) across 8 sites
- Connecting over 386 validators (covering ~16% of Solana stake)
- Handling real-world network disruptions smoothly with automatic failover to the public internet (IBRL mode)
A notable incident was a fiber cut on the Frankfurt–Prague route, where validators seamlessly switched to backup internet routes without downtime - a strong proof of the network’s resilience.

What to Expect on October 2, Mainnet-Beta Launch
Mainnet-Beta will bring major upgrades:
- 24+ global locations with over 59 high-capacity long-haul links
- Many routes upgraded to 100 Gbps and beyond
- Deployment of 57+ DZDs providing broad coverage and fault tolerance
- Network spans key cities including Amsterdam, Chicago, Dallas, Hong Kong, Mumbai, São Paulo, Tokyo, and more - with further expansions planned
- Collaboration with 11 independent infrastructure providers such as Jump, Rockaway X, Galaxy, and Jito
The broader network and increased validator participation will amplify performance gains and establish a reliable, fast, and resilient transport layer for Solana.

In summary: DoubleZero’s Mainnet-Alpha has successfully demonstrated meaningful speed improvements and reliable failover in a real-world environment. The upcoming Mainnet-Beta launch will significantly expand global reach and boost network capacity, enabling a new era of low-latency, high-performance blockchain infrastructure.
Stay tuned for October 2 for the next step in optimizing Solana validator connectivity.
