The Cardano roadmap is a summary of Cardano development, which has been organized into five eras: Byron, Shelley, Goguen, Basho, and Voltaire. Each era is centered around a set of functionalities that will be delivered across multiple code releases.
While the eras of Cardano will be delivered sequentially, the work for each era happens in parallel, with research, prototyping, and development often in progress all at once across the different development streams.
The work of each era is gathered and presented on its dedicated page, representing years of effort. Here you will find an overview of the goals of the era, as well as descriptions of the core functional components, links to associated academic research, status updates, and even real-time code commits.
