Cardstack

Cardstack is an experience layer designed to make blockchain technology more usable and scalable. Cardstack has several core components: Cardstack Framework, a software development kit used to build card-based blockchain apps, Cardstack hub, a hub used to coordinate data transfers across multiple blockchains and the cloud, and Tally, a protocol that uses proof-of-usage to validate and aggregate actions offline. Cardstack’s token, CARD, is intended to create a sustainable marketplace that fairly rewards open-source developers while allowing users to curate and use software services.
