about the technology

Hyperledger Fabric is a free, open source, and enterprise-grade framework for creating industrial blockchain applications. Fabric has been used to create online marketplaces, transparent insurance claims processes, and supply chain management apps for some of the world’s biggest companies. Its flexible SDK simplifies many challenges of blockchain development, letting developers write smart contracts and build client applications in either Java, JavaScript, or Go. The decentralized architecture of Fabric blockchain apps means that all parties must agree before a change is committed to a shared database—while still preserving privacy and data protection with Fabric’s selective sharing features.
