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.
