Public internet is a bottleneck for blockchain, according to the CEO of DoubleZero

The blockchain sector has matured and now requires physical communication infrastructure, according to Austin Federa, co-founder of DoubleZero.

Public internet infrastructure is the critical speed and performance constraint in high-performance blockchain networks, according to Austin Federa, co-founder and CEO of DoubleZero, a project that develops high-speed fiber optic communication rails for blockchains.

"The downside of public internet is that it was never built for high-performance systems. It was always designed for a relationship of one large server talking to one small server," Federa told Cointelegraph in an interview at Consensus 2025. The executive explained:

"We have validators all over the world. Rotating leadership schedules all the time. And then they go from having to be large consumers of data to being extremely large data emitters. This means they need huge amounts of resources both in input and output."
