DoubleZero Raises $28M to Build High-Speed Blockchain Infrastructure

DoubleZero CEO Austin Federa has highlighted the public internet as a significant bottleneck for high-throughput blockchain networks. According to Federa, the public internet's architecture, designed for one big server communicating with one little server, is inadequate for the demands of blockchain networks. These networks require validators distributed globally, with frequent leader rotations, and the ability to handle massive data consumption and broadcasting.

Federa emphasized that the public internet's limitations are now the primary constraint on blockchain performance, surpassing issues related to compute power or software development. He noted that the current infrastructure struggles to support the high data throughput and low latency required by modern blockchain applications. This constraint is particularly evident in decentralized finance (DeFi) trades, where high-speed communication is crucial for minimizing spreads and transaction fees.

DoubleZero, co-founded by Federa in 2024, aims to address these challenges by developing high-speed fiber optic communication rails specifically designed for blockchain networks. The project's goal is to reduce latency and increase bandwidth, making blockchains faster and more efficient. By providing dedicated, high-performance communication infrastructure, DoubleZero aims to open up new use cases for blockchain networks that were previously unavailable due to communication constraints.

In April 2025, DoubleZero conducted a validator token sale, offering token purchase agreements to accredited investors and active validators on high-throughput blockchain networks. The project successfully raised $28 million in capital and is planning to launch its public mainnet in the second half of 2025. Federa believes that the increasing throughput of blockchain networks and the overall development of the industry necessitate the construction of dedicated, high-performance communication infrastructure to meet the demands of increasingly sophisticated projects.
