In this episode I sit down with Grigore Roșu (Grigore Rosu), former NASA researcher and computer‑science professor, now building the Pi Squared Network. We dive into what Web3 really means (hint: it isn’t just blockchains). Grigore explains why the conventional blockchain model is inefficient, how his team is creating a parallel settlement network that scales, and what this could mean for everything from payments to gaming to AI‑agent economies. Whether you’re a founder, developer, or curious about the next wave of crypto infrastructure—you’ll get fresh insights plus a roadmap of what’s coming next.
Key Learnings
[00:00:00] The common idea that Web3 = blockchain is flawed — blockchains are one implementation, not the only way.
[00:05:00] How good academic ideas at university can migrate into startup innovations (Rosu’s lab → Runtime Verification → Pi Squared).
[00:06:00] The core scalability problem in Web3: transaction throughput and cost. Why traditional chains struggle.
[00:08:00] The paradigm shift: dropping “total order” of transactions across the network and moving to parallel, independent settlement.
[00:09:00] How the original blockchain design (chain + blocks + ordering) addressed double‑spending, but introduces a scalability ceiling.
[00:12:00] The potential: with massive parallelism, transaction cost could fall to “a hundredth of a cent” and throughput could reach millions per second.
[00:15:00] What this means for layers: If the infrastructure supports massive parallelism, the whole stack changes (Layer 1, Layer 2, app chains).
[00:21:00] Why the language ecosystem matters: restrictive smart‑contract languages (e.g., Solidity) limit developer adoption.
[00:30:00] Why it’s taken a decade for this to shift: new scientific results, protocol research, and building the infrastructure take time.
[00:36:00] Pi Squared’s roadmap: upcoming network launch, opening to validators, then expanding languages, reaching decentralization at scale.
[00:40:00] The “north star” metric: 1 million organic transactions per second. Makes everything else fall into place.
[00:43:00] Real use‑cases unlocked: Web3 gaming, AI agents interacting at speed, truly low‑cost settlement for mass‑market.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
