DoubleZero, a blockchain platform focused on high-performance communication for distributed systems, is moving closer to its mainnet beta launch, expected later this month. The step marks the beginning of phase two in its delegated program, following the rollout of the DoubleZero testnet earlier this year.
Testnet hiccup ahead of progress
The announcement comes shortly after DoubleZero disclosed a disruption in its testnet. On September 2, 2025, Solana validators participating in the DZ testnet lost their ability to communicate with non-validator nodes due to a routine software update. Despite the interruption, validators maintained uninterrupted connectivity with each other by failing over to the public internet, ensuring stability during the incident.
Strengthening Solana’s validator ecosystem
The upcoming mainnet beta builds on DoubleZero’s phase one initiative, which went live in July. That launch introduced a 3 million SOL stake pool through DoubleZero Staked SOL (dzSOL), a staking token representing delegated stake. The pool is designed to promote validator growth within the Solana ecosystem while boosting decentralization.
With phase two, DoubleZero plans to shift the stake pool into a validator expansion support program. A key focus will be on geographically underrepresent regions, broadening the diversity of Solana’s validator network.
Building a blockchain-ready network
Engineered for blockchain use cases, DoubleZero provides low-latency, high-bandwidth infrastructure to improve block propagation, scalability, and overall network decentralization. Its native token, 2Z, serves as the backbone of the ecosystem, supporting utility, efficiency, and security.
Backing its ambitious roadmap, DoubleZero secured $28 million in March 2025 through a token funding round led by Multicoin Capital and Dragonfly.
If the mainnet beta goes as planned, DoubleZero could position itself as a critical piece of infrastructure for Solana and other blockchain ecosystems seeking reliable, high-speed communication layers.
