This week’s Community Hour celebrated the culmination of the Games on Microchains builder challenge! We announced the winners, showcased the standout submissions, and even played a few of the games live. From ultra-fast gameplay to creative mechanics powered by Linera’s microchains, it was a showcase of what real-time onchain gaming can look like ⛓️

This POAP commemorates Linera’s Testnet Babbage launch—the second major milestone in our testnet rollout. Building on the success of Archimedes, Babbage introduces powerful upgrades including a trustless web client, configurable PoW microchains, and Ethereum-compatible signatures, pushing Linera closer to its vision of real-time, user-centric blockchain infrastructure. During our April 17th AMA, Linera founder Mathieu Baudet was joined by key validator partners to discuss the technical advances in SDK v0.14, the role of AI-integrated oracles, and our evolving roadmap. Attendees got a firsthand look at the future of scalable microchain apps and Linera’s bold steps toward mainnet.
