DoubleZero, a project spearheaded by Austin Federa, addresses the critical bottleneck hindering high-throughput blockchain networks: public internet infrastructure. Federa, in a Cointelegraph interview at Consensus 2025, highlighted the inherent limitations of the public internet, designed for a “one big server to one little server” model, rather than the complex, high-bandwidth demands of modern blockchains.
Validators on global blockchain networks experience constant shifts between massive data consumption and broadcasting, requiring substantial ingress and egress resources. This public internet constraint, according to Federa, now surpasses compute power and software development as the primary limitation on blockchain performance.
DoubleZero aims to alleviate these limitations by constructing dedicated, high-speed fiber optic communication rails for blockchains. This specialized infrastructure promises to significantly improve network speed, reduce spreads in decentralized finance (DeFi) trades, lower transaction fees, and unlock previously inaccessible use cases.
Founded in 2024 after Federa’s departure from the Solana Foundation, DoubleZero focuses on reducing latency and increasing bandwidth. An April 2025 validator token sale, exclusively for accredited investors and existing validators on high-throughput networks like Solana, Celestia, Sui, Aptos, and Avalanche, successfully raised capital to support the project.
Following a $28 million funding round, DoubleZero plans a public mainnet launch in the second half of 2025. The project’s necessity stems from the escalating throughput demands of increasingly sophisticated blockchain projects, demonstrating the need for dedicated, high-performance communication infrastructure to support the industry’s growth. The company’s whitepaper offers additional information on their technical approach.
