Learn about Blockstack
From the blockchain, to smart contracts, and decentralized apps
idMA (built on Stacks Blockchain) inherits Bitcoin's security through Proof of Transfer, enables you to write secure smart contracts with Clarity, and brings it all together in one decentralized network maintained by developers from all over the world. More than 500 teams are already building on Blockstack.
Data storage and user accounts
With decentralized data storage and accounts, everything your users do will be private and owned by them. It’s powered by the blockchain but integration is easy — all you need is a few lines of JavaScript.
Smart Contracts
Clarity smart contracts are self-executing, public code that run on the Stacks blockchain. Use smart contracts to build new kinds of apps and protocols that operate without a central authority, control digital assets, and enable trustless interactions.
Use cases
With user-owned data and smart contracts, you can build new kinds of apps that couldn’t exist before.
Create alternatives to everyday apps where users’ privacy is guaranteed with encryption.
Build trustless, auditable financial products that run without a central authority.
With smart contracts, players know your game is fair and can take digital assets from game to game.
Enable people to buy, sell, and trade anything without central authorities.
Create your own digital assets with the Bitcoin blockchain as their foundation.
All-in-one platform
The Stacks blockchain inherits the security of the Bitcoin blockchain through its consensus mechanism, Proof of Transfer.
Clarity is Blockstack’s language for writing smart contracts that has been adopted by multiple projects in the space. Clarity is designed by top computer scientists to be secure and reliable.
Build decentralized apps using JavaScript, TypeScript, or any of your preferred frameworks like React, Vue, or Angular.
Users get a blockchain-generated key that unlocks their account and data storage.
Data is stored independently from your app, in a place controlled by the user's key. Your app can scale without any data costs.
Blockstack is built by developers like you from all over the world, and not controlled by anyone.
