Approved: Running Linera Microchains on the Acurast Edge Fleet
In a recent proof-of-concept, Linera’s team demonstrated that a Linera client can be deployed and run on Acurast’s decentralized edge network with no modifications to the existing code. The demo proceeded as follows:
Wasm bundle streaming: A JavaScript bundle which embeds Linera’s WebAssembly module was pushed to an attested Acurast device.
Runtime initialization: The device executed the Linera runtime, connected to the Linera Babbage testnet faucet, and created a new wallet.
Microchain instantiation: Using that wallet, the client claimed a fresh microchain and logged its chain ID to the console, successfully completing the entire flow.
Under the hood, the Linera client is itself a Wasm module that dynamically loads and runs other Wasm modules, and it uses Web Worker APIs to spawn background threads and share memory between them. All of this executes unchanged in Acurast’s secure, sandboxed runtime. Moreover, the client runs a full, sparse Linera node on-device, including local state management and on-chain contract execution, instead of merely proxying RPC calls to an external service.
For Linera’s founder, Mathieu Baudet, this work confirms Linera’s edge readiness and Acurast’s versatility:
“This opens many possibilities such as running Linera block producers and (later) Linera auditors in Acurast.”
We’re pleased to share this demonstration of seamless integration between Linera’s microchain architecture and Acurast’s secure, sandboxed edge fleet. This demonstrates the versatility of Acurast and its perfect fit for Web3 applications. The GitHub repository of the demo can be found here: https://github.com/linera-io/acurast-demo. Further updates will follow as we continue to explore and document this collaboration.
About Linera
Linera was founded with the vision of empowering users through globally accessible, decentralized infrastructure that facilitates real-time interactions between clients, chains, and services. Its novel architecture lets users interact directly with small chains of blocks, called microchains, allowing applications to read and write on-chain data with strong guarantees of performance and security. Founder and CEO, Mathieu Baudet, PhD, was an early research engineer on the Meta Libra/Novi project and is a coauthor of the FastPay protocol.
