Podcast Summary: CRYPTO 101 - Ep. 649 A New and Faster Internet with DoubleZero

Release Date: April 8, 2025

Hosts: Bryce Paul & Brendan Viehman
Guest: Austin Federa, Co-founder of Double Zero

1. Introduction

In Episode 649 of CRYPTO 101, host Bryce Paul welcomes Austin Federa, the co-founder of Double Zero, to discuss the groundbreaking advancements Double Zero is bringing to the blockchain and internet infrastructure. Despite Brendan Viehman's absence, Austin and Bryce dive deep into the intricacies of rebuilding the internet to better support blockchain technologies.

2. Understanding Double Zero

Austin Federa begins by outlining the core mission of Double Zero:

Austin (01:27): "Double Zero is set out to solve what I think we'd call like a fundamental problem facing blockchain today... we're building the physical cables that the Internet runs on."

Double Zero's primary goal is to overhaul the existing internet infrastructure, which has been patched together over four decades, to better accommodate the high demands of modern blockchain networks. Unlike typical new internet services that focus on platforms like Facebook or Google, Double Zero targets the very backbone—the fiber optic cables that form the global internet.

3. The Current Internet and Its Limitations for Blockchain

Austin elaborates on the inefficiencies of the current public internet system:

Austin (08:04): "Most of the public Internet runs on fiber cables... it's built on 40 years of cobbled together different types of systems."

He compares the public internet to specialized private networks used in high-frequency trading (HFT), where speed and efficiency are paramount:

Austin (09:57): "...most large public companies aren't using the public Internet as much as specialized private lines because they need that speed and reliability."

In the context of blockchain, this reliance on the public internet leads to significant inefficiencies:

Austin (10:14): "If you're a Solana validator or an Ethereum validator, you are sending out copies of your block to every single other node... it's a very inefficient system."

These inefficiencies limit the scalability and speed of blockchain networks, making it challenging to achieve high transaction throughput.

4. How Double Zero Addresses These Limitations

Double Zero seeks to introduce multicast technology to the public internet, a method commonly used in home networks for streaming to multiple devices simultaneously:

Austin (10:57): "Multicast allows the server to send the packet once and the network gets it where it needs to go. This is not how things exist today."

By implementing multicast, Double Zero aims to reduce the redundant data transfers that plague current blockchain networks, thereby enhancing speed and reducing bandwidth usage.

Additionally, Austin highlights the importance of dependable connections:

Austin (13:25): "Just as with video conferencing, where packet loss can degrade the experience, blockchain transactions require 100% reliability to maintain integrity."

5. The Technology Behind Double Zero

Double Zero employs several advanced technologies to achieve its goals:

• Hardware-Accelerated Filtration: Utilizes FPGAs for tasks like signature verification and transaction deduplication to filter out malicious or redundant data before it affects the network.

  Austin (25:00): "We use Shapley values to determine the incremental value that each link produces in the network and compensate them as such."

• Decentralized Infrastructure: By partnering with multiple independent contributors, Double Zero ensures resilience and avoids central points of failure.

  Austin (30:44): "By building this with multiple independent contributors, the network is much more resilient."

• Revenue Share Model: Contributors are rewarded with a percentage of the economic activity passing through their provided bandwidth, aligning incentives across participants.

  Austin (38:20): "People will actually be paid as a percentage of the economic activity going over it."

6. Integration with Blockchain Networks

Double Zero is designed to be network-agnostic, allowing seamless integration with various blockchain platforms:

Austin (32:48): "With RPCs and MEV systems as primary users of the network, users may not even know their transactions are going through Double Zero."

For Layer 1 (L1) and Layer 2 (L2) solutions, Double Zero offers flexibility:

• L1 Networks (e.g., Solana, Ethereum): By adopting Double Zero, validators can significantly reduce the time and bandwidth required to propagate blocks across the network.
• L2 Solutions: Centralized sequencers can leverage Double Zero for enhanced security and performance without major protocol overhauls.

7. Incentive Mechanisms and Tokenomics

To foster participation and growth, Double Zero integrates a robust token-based incentive structure:

Austin (38:20): "Tokens work best for incentive alignment... contributors are rewarded based on the value they add to the network."

This model ensures that bandwidth providers are compensated fairly based on the actual utility and demand of their contributions, promoting a healthy and scalable ecosystem.

8. Navigating the Political and Regulatory Landscape

Austin addresses the evolving political climate surrounding cryptocurrency and blockchain:

Austin (41:22): "The change in tone of the SEC... has been really, really interesting to watch."

He emphasizes the importance of crypto foundation repatriation—encouraging crypto businesses to re-establish operations within the United States for greater stability and legal protection.

Austin (44:14): "The United States is the best country in the world to build a business in... crypto foundations are able to move back to the United States."

This strategic positioning aims to align Double Zero with supportive regulatory environments, ensuring long-term sustainability and growth.

9. Future Plans and Mainnet Launch

Double Zero is currently in the testnet phase but is on track for a mainnet launch within the year:

Austin (39:46): "We are aiming to go live this year with mainnet."

Post-launch, Double Zero envisions a highly scalable network capable of handling millions of transactions per second, positioning itself as a pivotal infrastructure layer for the next generation of blockchain applications.
