How does it work?
sBTC enables the Bitcoin economy
Each request requires approval from 70% of signers before it can be processed. As a signer, this work of processing requests is largely automated and handled by the software.
In order to participate, signers are required to lock up STX tokens (the gas token on the Stacks network), and in exchange for their work, signers earn BTC rewards that are generated by Stacks’ consensus mechanism Proof of Transfer.

DepositTo mint sBTC, users deposit an equivalent amount of BTC in a script on the Bitcoin blockchain. This script is controlled by the network of signers, who then mint sBTC and send it to the user’s Stacks address.
WithdrawTo burn sBTC, users submit a peg-out transaction to the network. Signers process those requests and send BTC to the user’s Bitcoin address.

sBTC is an open-membership protocol, meaning anyone can participate in signing by locking their STX in consensus. The minimum amount of STX required to become a signer is dynamically set and currently requires ~90,000 STX.
Signers can choose to operate on their own or delegate STX to a signer pool instead, if they don’t have enough STX to sign on their own or don’t want the overhead of running the software themselves.
