Linera enables real‑time coordination for decentralized physical infrastructure networks (DePIN) and IoT systems. Traditional chains cannot handle the microtransactions and responsiveness these networks require. With Linera, each device or component runs on its own microchain, processing data, verifying outputs and settling payments independently. This supports real‑time energy tracking, usage‑based pricing and automated rewards for bandwidth, compute or power contributions. Parallel microchains provide local autonomy with global composability, giving DePIN builders scalable infrastructure with built‑in responsiveness and instant settlement.
