Motema: The ZKML Geiger Counter

ETH Oxford 2024 WinnerZero-Knowledge MLSocial Impact

Motema (Lingala for "heart") is a revolutionary system that enables direct donations to Congolese cobalt miners by proving their exposure to mining environments through Zero-Knowledge Machine Learning. This technical deep dive explores the intersection of hardware sensors, cryptographic proofs, and blockchain infrastructure.

Technical Deep Dive Available on GitHub

This project represents a comprehensive implementation of Zero-Knowledge Machine Learning for social impact, combining Flipper Zero hardware, Cairo proofs, and Ethereum smart contracts to create direct donation channels for Congolese cobalt miners.
