Microchains are lightweight chains that operate in parallel within a common set of validators.
Altogether, the core innovation of microchains is to put users at the center of the protocol by allowing them to manage the production of blocks in their own chains without trading off security or finality guarantees. This framework not only guarantees optimal performance for transaction latency and fees, but it also ensures that users have direct, local access to their on-chain data, enhancing transparency and accessibility.
The concept of microchains looks at scalability from a new perspective: scaling at the validator level instead of at the blockchain level. The result is a game changer for web3 applications that require quick on-chain interactions between an unlimited number of users.
Microchains are a preferable solution for many web3 use cases due to their flexibility and ability to ensure that applications can consistently and predictably perform at scale, for any number of users. Some important use cases for Linera include:
Real-time coordination and data streams in decentralized physical infrastructure (DePIN)
Version control systems for software, data pipelines, or AI agents
Micro-rewards and low-latency user interactions in web3 gaming
Beyond scalability, the advantages of the microchain approach are also seen in an improved user experience as well as added transparency and data accessibility. One way to look at microchains is to see them as a step away from monolithic blockchains and their layered, modular add-ons, and as a step towards what we could call The Personal Blockchain.

Mathieu Baudet is the founder and CEO of Linera, the first low-latency blockchain designed to scale elastically through the introduction of microchains. During his nine-year tenure as an infrastructure engineer and researcher at Meta (formerly Facebook), Mathieu was instrumental in the development of the Libra/Novi project, where he worked on an academic protocol called FastPay which laid the foundations for the Linera protocol. Mathieu holds a PhD in Computer Science from École Normale Supérieure Paris-Saclay and specializes in BFT consensus protocols, cryptographic protocols, and formal verification.
