A presentation at Hyperledger’s Media and Entertainment Special Interest Group on June 1, 2021 with Chris Tse, Founding Director of Cardstack. Cardstack is an open source framework that enables Web 3.0. “Cards” form the building blocks that allow for bringing in data from disparate sources, beautiful UI animations, encapsulated and flexible data schemas, and a quick ramp-up experience. Both JavaScript developers and end-users are empowered to add common application features (CMS, notifications, authentication) using the Card SDK.
