Interest and energy has been pouring into the Hyperledger Project which was launched in 2016 by the Linux Foundation to provide blockchain technologies for the enterprise. Blockchain technology is the underpinning of Bitcoin, but its application goes far beyond alternate currencies. Blockchain can be used to address information-management problems in a decentralized manner. This is valuable not only to the financial industry, but also in healthcare, environmental monitoring, emerging-market credit, supply chains, even education. This presentation covers how this community of open source communities is organized, the different projects they focus on, and provides an introduction to Fabric, the blockchain framework IBM has contributed.
