We’re back from ETHCC 2025 in Cannes and ready to share highlights from the trip! Danny returns to host alongside community mods Myz Julz and Josiah, diving into how Linera’s hyper-modular architecture enables unlimited blockspace—and what that means for builders and users alike. As always, we’ll cover the latest meme challenge, tournaments, and community updates ⛓️

This week’s Community Hour POAP was again claimable live via secret word! We shared updates on the Games on Microchains builder challenge, other active game tournaments, and the latest meme challenge. We also celebrated major momentum from our Drops campaign, including an all-time high in Twitter followers (+46K!) and over 152,000 submissions. Huge welcome to all our new Linerans joining the real-time blockchain revolution ⛓️

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.
