- Public internet infrastructure limits blockchain network speed and performance, according to DoubleZero CEO Austin Federa.
- DoubleZero is developing dedicated, high-speed fiber optic rails for blockchains to address these constraints.
- The project aims to reduce data travel times and increase bandwidth for global blockchain validators.
- DoubleZero raised $28 million for its mainnet launch, targeting the second half of 2025.
- A validator token sale in April 2025 invited accredited investors and current validators from major blockchains.
Austin Federa, co-founder and CEO of DoubleZero, says that slow public internet infrastructure is blocking the speed and growth of high-throughput blockchain networks. He outlined the company’s solution at Consensus 2025 in Toronto, where DoubleZero is working to introduce high-speed, fiber optic communications for blockchain projects.
DoubleZero seeks to fix problems like high latency—the delay before data moves across a network—and bandwidth limits, or the amount of information a network can handle at once. In June 2025, the project completed a $28 million capital raise, which will help towards its public mainnet launch later this year.
Federa explained that current internet systems were not designed for large-scale, high-speed data sharing. He noted that blockchain validators, who check and confirm transactions, have unique demands. “We have validators all around the world. Rotating leader schedules all the time. And then they switch from having to be massive consumers of data to extremely massive broadcasters of data. So that means that they need huge amounts of resources both on ingress and egress,” he said.
Federa added that the bottleneck for blockchain networks is now in communications infrastructure, not computer power or software. Networks with dedicated, faster communications—like those DoubleZero is developing—may help make blockchains quicker, reduce decentralized finance trading fees, and enable new applications.
Founded in December 2024 after Federa left the Solana Foundation, DoubleZero aims to serve high-speed blockchain networks such as Solana, Celestia, Sui, Aptos, and Avalanche. In April 2025, the company conducted a validator token sale for accredited investors and active validators from these chains.
DoubleZero has released a technical whitepaper available at this link for further details about its infrastructure plans. The team is planning an official mainnet launch in the second half of 2025.
