No More Traffic Jams: Grigore Roșu on Fixing Blockchain’s Congestion

Tech Snippets Today with Joseph Raczynski

Imagine a world where every street in a city speaks a different language, uses a different currency, and has its own quirky set of toll booths. Welcome to the current state of blockchain—a sprawling metropolis of over 1,000 networks and 16 million cryptocurrencies, most of them abandoned vehicles rusting by the curb. Navigating this chaotic landscape is like weaving through Manhattan traffic before congestion pricing—confusing, slow, and full of unexpected detours.
Now, enter the cross-chain bridges—the overworked translators of this digital city. Some are robust, handling dozens of chains and hundreds of tokens; others, well, let’s just say their “security audits” might have been written in Comic Sans. It’s a mess, and the stakes are high.
But what if there was a better way? What if we could bypass the traffic, break down the barriers, and create a blockchain city where everyone speaks the same language, and trust isn’t just a buzzword?
That’s where today’s guest steps in.
Meet Grigore Roșu: former NASA engineer, professor of computer science at the University of Illinois, and the brilliant mind behind the K Framework—a true “Rosetta Stone” for programming languages. As a day-one contributor to Ethereum and the founder of Runtime Verification, Grigore has spent his career making the digital world safer and smarter. Now, as Founder & CEO of Pi Squared, he’s tackling blockchain’s biggest challenge: interoperability without compromise.
In this episode, we’ll dive into Grigore’s fascinating journey from NASA to Web3, explore how Pi Squared is building the missing trust layer for a truly modular and interoperable blockchain ecosystem, and ask the big questions:
Do we really need all these L2s?
What’s the future of AI agents on-chain?
And can we finally achieve seamless, verifiable cross-chain computation—without bridges or centralized middlemen?
If you’re a developer, crypto enthusiast, or just love a good story about solving impossible problems, you won’t want to miss this conversation. Get ready to rethink what’s possible in Web3—because with Grigore Roșu and Pi Squared, the road ahead just got a whole lot smoother.
