STX Stacks

• Developer tools – Comprehensive programming libraries are available for a wide range of environments such as web, iOS, and Android. Our libraries are designed to require no additional language or protocol knowledge — any Javascript developer can build a Blockstack app in one hour.
• Stacks blockchain – Designed with security, scalability, and speed in mind. We use tunable proof-of-work to allow developers to strike the right balance between speed and reliability. For app builders, we abstract all blockchain complexity into simple Javascript APIs.
• Authentication – Easily include user registration and authentication with Blockstack IDs. Profile security is enforced by the Stacks Blockchain and Blockstack Naming Service (BNS), leaving credentials and identity management in user’s hands.
• Data storage – Users assume responsibility of their data — it’s stored in a location of their choice and not on your servers. As a developer, you do not need to pay for database maintenance costs, so you can focus on what you do best: improving the functionality of your app.
• Clarity Smart contracts – Clarity is a decidable, interpreted smart contract language that optimizes for predictability and security. It empowers you to be certain of how your code behaves prior to pushing it into production, so you don’t have to worry about security issues, side effects, or unexpected fees.
• Build an app and get paid instantly with App Mining – Every month we pay out $200,000 to the best apps built on Blockstack. The better your app, the more you earn.

Blockstack for Dapp builders

Blockstack for users

• User-owned identity – With the old internet, big companies own your login. With Blockstack, you own your login. Under the hood, Blockstack uses blockchain to keep everything secure and private.
• True data ownership – With the old internet, big companies own your data. With Blockstack, relax knowing your data is 100% private, and only you can grant access to apps or other users. Never worry about privacy breaches again.
• One ID, 100s of apps – Discover a universe of new apps where your digital rights are respected. Share, swap, and connect data between apps however you want.
