Blockstack is a new decentralized internet where you own your data and your apps run locally without remote servers.
Blockstack provides decentralized services for naming/DNS, identity, authentication and storage. Developers can use JavaScript libraries to build serverless apps and they don't need to worry about managing infrastructure. Blockstack replaces the current client/server model; users control their data, apps run client-side, and the open Blockstack network replaces server-side functionality.
