SusChain vs WHIMO

SusChain is a free, open source platform for visualizing, capturing, enriching, and sharing supply-chain information about raw-material sourcing. It creates a verifiable digital trail for tracing materials and presenting supply-chain data to consumers. Transaction records can be matched with regional economic data to help assess whether growers receive a real living income. Users choose which information is public and which remains private, with cryptographic controls securing those choices. Configurable data structures, a localizable interface, and a browser-based front end support adaptation across regions and operations. An open API and plugin universe provide extension options. Progressive block signing is intended to make recorded transactions immutable, externally verifiable, and traceable. SusChain is designed for remote areas with variable connectivity and low-cost, low-power hardware. It can run on local, cloud-based, or hybrid infrastructure, from small businesses through multinational supply operations. The Free plan costs nothing and permits running, modifying, and distributing the platform.

WHIMO captures and shares supply-chain transaction and geolocation data from origin to destination. It is designed for cooperatives, local aggregators, transporters, processors, and exporters, including people working in low-infrastructure contexts. Users can record buying, collecting, selling, and delivery transactions, track traded volumes, document raw materials becoming processed products, and review transaction history. Farm locations can be added by scanning QR codes, recording GPS locations, dropping map pins, or entering geolocation later. WHIMO can display supply chains across direct and indirect suppliers, measure geodata coverage for transactions, and help users request missing location data. Participants can collect traceability information from suppliers, transfer it to customers, view supply-chain diagnostics, and download data for due diligence. The service is available on Android, iOS, and the web, with an option to self-host. The European Forest Institute hosts a ready-to-use version and manages its data under its data policy; companies and institutions can also replicate and adapt the open-access source code for their own system. WHIMO is free and based in Joensuu, Finland.
