Why build on Stacks
The best of both worlds
On Stacks you get the security of Bitcoin and the speed and flexibility of Stacks. All Stacks transactions on the Bitcoin blockchain, making your apps as secure as a Bitcoin transaction.
Secure smart contracts
Security is critical for smart contracts—Clarity is optimized for security, eliminating many common smart contract bugs.  Perfect for high-stakes code where bugs are not an option.
Innovate on Bitcoin
On Stacks, you can build Bitcoin-based logic into your smart contracts. Clarity has visibility into Bitcoin state and has built-in SPV proofs. This makes innovating on Bitcoin much easier.
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.
