Blockstack uses the lower layers of the traditional internet and focuses on decentralizing the application layer. Blockstack provides key tools and infrastructure to developers enabling decentralized storage and decentralized authentication & identity. Developers build single-page applications in JavaScript then plug into user-run APIs, which eliminates centralized points of control. Users run decentralized apps through the Blockstack browser and give explicit read/write permissions to their data. Information is encrypted and stored on users’ personal devices. There are no middlemen, no passwords, and no massive data silos to breach.

I'd encourage everyone to take a look at blockstack.org and feel free to review Graphite's repo (it's 100% open source): https://github.com/jehunter5811/graphite-blockstack
