Stacks

A better internet, built on Bitcoin

Stacks makes Bitcoin programmable, enabling decentralized apps and smart contracts that inherit all of Bitcoin’s powers.

Build apps and smart contracts on Bitcoin

Stacks connects to Bitcoin, enabling you to build apps, smart contracts, and digital assets that are integrated with Bitcoin's security, capital, and network.

Start building

Earn Bitcoin by Stacking

Lock your STX temporarily to support the network’s security and consensus. As a reward, you’ll earn Bitcoin that miners transfer as part of Proof of Transfer.

How much could I earn?

Reimagine our financial system on Bitcoin

Stacks makes Bitcoin's $760B of capital programmable with smart contracts. Build a better financial system on top of Bitcoin that’s open, composable, and without intermediaries.

Mining

Mining is the process of adding new blocks to the Stacks blockchain. With Proof of Transfer, miners spend Bitcoin to mine new blocks — no special hardware is required.
