DoubleZero: A Faster Future for Blockchains?

Austin Federa, formerly of the Solana Foundation, is launching DoubleZero, a protocol aiming to dramatically improve blockchain communication and scalability. In a recent interview, Federa shared his vision for a high-performance networking layer that could underpin the next generation of decentralized systems.

What is DoubleZero?

DoubleZero aims to be faster than the internet, providing a crucial edge for crypto trading. Federa likens it to "crypto’s version of Flash Boys," emphasizing the importance of rapid data transfer between market participants. By allowing multiple contributors to contribute their fiber networks, DoubleZero builds a high-performance fiber mesh network connecting people globally.

Why Solana?

While DoubleZero isn't built on Solana, it supports Solana first due to its unique ratio of transactions per second to node count. Solana's high performance and large node count make it particularly susceptible to communication bottlenecks. DoubleZero aims to alleviate these bottlenecks without sacrificing decentralization.

Staking and Mainnet Launch

Currently, a small percentage of SOL is staked on the DoubleZero testnet to subsidize validator costs. The mainnet launch is scheduled for September and will feature numerous fiber links, significantly faster than current connections. This enhanced capacity could enable Solana to increase its transaction limits.

Addressing Concerns about Inequality

A key concern is whether DoubleZero creates a performance inequality among validators. Federa argues that the public internet is already a centralizing force. DoubleZero is designed with redundancy. If the DoubleZero network experiences issues, the public internet serves as a fallback, ensuring censorship resistance, albeit with reduced transaction speeds.

What's Next?

The focus leading up to the September mainnet launch is rigorous testing and preparation for a token launch.

Key Takeaways:

• DoubleZero aims to provide a faster, more efficient communication layer for blockchains.
• It focuses on Solana first due to its high performance and node count, which create communication bottlenecks.
• The protocol is designed with redundancy to ensure censorship resistance and a fallback to the public internet.
