SustainBlock is a blockchain-based project to demonstrate the presence of artisanal and small-scale mining (ASM) mine sites in the supply chain of mineral and metal end-users, and in turn provide downstream companies with access to information on the provenance of minerals contained in their products.

The goal of this project is to create a blockchain-enabled system for tracking the provenance of certain raw materials produced in conflict-affected and high-risk areas – e.g. Conflict Minerals (3TG) – across the entire supply chain via verified, cryptographically secured transactions. With support from the European Partnership for Responsible Minerals (EPRM), the project will be piloted in 2019 along a mineral supply chain originating from Rwanda.
