Public Internet infrastructure is the constraint of speed and critical performance on high-speed blockchain networks, according to Austin Federa, co-founder and CEO of Doublezero, a project developing fiber optical communication rails for blockchains.
“The disadvantage of the public internet is that it has never been designed for high performance systems. It has always been designed for this type of relationship of a large server speaking to a small server,” said Federa at Cointelegraph in an interview with 2025 consensus. The executive explained:
“We have validators all over the world. Turning leader programs all the time. And then they have to be massive data consumers to extremely massive data diffusers.
The executive added that the constraint posed by public internet infrastructure is now the limiting factor in blockchain performance and not energy or software development.
Networks like DoubleZero will make blockchains more quickly, reduce the deviations from decentralized financial transactions (DEFI), lower transaction costs and open new use cases for blockchain networks which were not previously available due to communication infrastructure constraints.

Doublezero co-founded by Austin Federa in 2024
Austin Federa left the Solana Foundation to establish the Doublezero protocol in December 2024. The goal of the project is to reduce latency, the time required for data to travel in a network and bandwidth – maximum data traffic that a network can manage both.
In April 2025, Doublezero made a sale of validator tokens to sell tokens purchase agreements for interested nodes operators seeking to become validators for the network.
The sale of tokens was only available for accredited investors and validators already active on high speed blockchain networks, notably Solana, Celestia, Suit, Aptos and Avalanche.
The Doublezero team aims to launch its public maintenance in the second half of 2025, following a capital increase of $ 28 million.
Fedea told Cintelegraph that the increasingly high speed of blockchain networks and the overall development of industry required the construction of a dedicated high performance communication infrastructure to meet the demand for increasingly sophisticated projects.
