Hey there! If you’re into blockchain tech or just curious about the latest innovations, you’re in for a treat. On March 6, 2025, DoubleZero Foundation dropped some exciting news on X: they’ve raised $28 million in a token round to build something called IBRL—a high-performance fiber network designed specifically for blockchains and distributed systems. Let’s break it down in simple terms and see why this matters.

What’s DoubleZero Up To?

DoubleZero isn’t your typical blockchain project. Instead of focusing on a Layer 1 (like Ethereum) or Layer 2 (like Arbitrum) solution, they’re introducing something new: an “N1” network. Think of it as a neutral, base-layer infrastructure that’s all about super-fast connectivity for distributed systems—like blockchains, but not limited to them. The idea is to tackle a big problem: the internet we use today wasn’t built for high-performance, decentralized systems like blockchains.

The current internet struggles with things like unpredictable delays (latency), inconsistent bandwidth, and slow packet routing. For blockchains, where thousands of validators (computers that confirm transactions) need to agree across continents, these issues can really slow things down. DoubleZero’s solution? Build a dedicated, high-speed fiber network that prioritizes blockchain traffic, potentially hitting speeds of 1 million to 100 million transactions per second (TPS). That’s mind-blowing compared to what most blockchains can handle today!

Why Now? The Physics Wall

DoubleZero’s thread explains that software tweaks can only go so far. After years of optimizing blockchain code, we’ve hit what they call a “physics wall.” No amount of coding can beat the speed of light or the limitations of public internet networks. So, the real bottleneck isn’t in the software—it’s in the physical infrastructure underneath. That’s where IBRL comes in, acting like a superhighway for blockchain data, letting validators focus on making blocks instead of fighting network lag.

Who’s Behind This?

This isn’t a solo effort. DoubleZero’s token round was co-led by big names like Multicoin Capital and Dragonfly, with support from other heavy hitters like Foundation Capital, Borderless Capital, and Jump Crypto. Core contributors include Malbec Labs, Anza, and Jito Labs, who are helping design this permissionless, global network. It’s a collaborative push to rethink how blockchains connect to the world.

What’s the Big Deal for Blockchains?

For blockchains like Solana, which already boasts impressive speeds, DoubleZero could be a game-changer. The thread mentions that DoubleZero’s network quietly powered Solana’s 1 million TPS demo at last year’s Solana Conference during the Firedancer presentation. Now, they’re rolling out a permissioned testnet beta across seven global hubs (Singapore, Tokyo, Los Angeles, New York, London, Amsterdam, and Frankfurt), giving Solana validators and RPCs (remote procedure calls) a chance to test it out.

But it’s not just for Solana—DoubleZero is blockchain-agnostic, meaning it can benefit any high-performance distributed system. Whether it’s gaming, AI, or other tech needing low latency and high throughput, this network could make a huge difference.

How Does It Work?

DoubleZero’s approach is pretty cool. They’re tapping into underutilized fiber optic bandwidth from network contributors like Jump Crypto and Distributed Global. This bandwidth forms the backbone of IBRL, a permissionless network where anyone can contribute or use it. The network also uses specialized hardware, like Field-Programmable Gate Arrays (FPGAs), to filter out spam and duplicate messages at the edge, making things faster and more efficient for validators.

What’s Next?

Right now, the testnet is live but limited to invited validators, with plans to go permissionless later in 2025. If you’re a validator or just excited about this tech, you can apply through DoubleZero’s website or check out their job openings—they’re hiring globally to build this “alternative to the public internet.” The full press release is available here, if you want to dive deeper.

Why Should You Care?

This isn’t just tech geek stuff—it’s a peek into the future of how blockchains and distributed systems might operate. By addressing the physical limitations of the internet, DoubleZero could unlock new levels of speed and scalability, making decentralized apps faster and more reliable. Plus, with $28 million in funding and support from top crypto investors, it’s clear this project has momentum.

So, whether you’re a crypto enthusiast, a tech nerd, or just curious about the next big thing, DoubleZero’s N1 network is worth keeping an eye on. It’s a bold step toward reimagining the internet for a decentralized world—literally from the ground up!
