MicroSui lightweight, open-source C framework brings the Sui Network to microcontrollers

MicroSui (Sui Embedded Framework) is a lightweight, modular, open-source C framework that brings the Sui Network to microcontrollers from low-end 8-bit MCUs like AVR to more powerful 32-bit SoCs like the ESP32. Wait… What’s the Sui Network / Protocol exactly? It’s a blockchain platform designed for high-speed, scalable, and low-cost decentralized applications, which was introduced in May 2023 by Mysten Labs, a company founded by former Meta engineers. It competes with networks like Solana and Ethereum but with better performance. So far, the Sui Network works with web and mobile applications, but MicroSui aims to expand its usage to resource-constrained embedded devices. We’re told MicroSui provides support for all core operations such as key management, transaction construction, signing, and broadcast. It is a pure-C library with no OS dependency or dynamic memory usage, so it can be deployed on a wide range of microcontrollers. Higher-end microcontrollers with Internet access, such […]
