Millions of Blockchains. One Protocol. Meet Linera.

In this episode of the TEACHMEDEFI podcast, we speak with Mathieu
Baudet, founder of Linera and former cryptographic researcher at
Facebook’s blockchain division. Mathieu shares his journey from
academia to building next-generation blockchain infrastructure
and introduces Linera—a novel protocol focused on horizontal
scalability through microchains, or “personal chains.”


We dive into the design philosophy behind Linera, including how
it differs from traditional monolithic and sharded chains by
offering each user their own blockchain environment. Mathieu
explains how this model enables real-time interactions and
efficient computation while avoiding competition for block space.


The conversation also covers validator dynamics, centralization
trade-offs, and Linera’s approach to block delegation. We discuss
the recent launch of their testnet, how AI agents could interact
with their own microchains, and the types of Web3 applications
Linera is best positioned to support. Whether you're building
next-gen infrastructure or exploring the limits of blockchain
scalability, this episode offers valuable insight into what the
future could look like.


About Mathieu Baudet & Linera


Mathieu Baudet holds a PhD in cryptographic protocols and
previously worked at Facebook on the Diem blockchain. As the
founder of Linera, he’s now building a scalable Layer 1 designed
for real-time applications through its unique microchain
architecture. Linera aims to support millions of chains running
in parallel while preserving decentralization and performance.
