Muneeb Ali, the co-creator of the Stacks blockchain and CEO of Trust Machines, recently hinted at an exciting development for the Stacks network: its next major upgrade is on the way. Stacks, a blockchain that aims to bring scalability and programmability to Bitcoin, has set its sights on releasing a new asset, sBTC, potentially as soon as early December. Ali shared the update in a recent post on X (formerly Twitter), where he confirmed that sBTC v1 is on track for launch, with further enhancements expected to roll out in January and beyond. $STX
The introduction of sBTC marks a significant step forward for Bitcoin’s decentralized finance (DeFi) capabilities, addressing a key limitation often referred to as Bitcoin’s “write problem.” Writing data directly to Bitcoin’s main chain—the core ledger that records all transactions—is a challenging task, especially for decentralized applications (dApps) and smart contracts that need to operate seamlessly within the Bitcoin ecosystem. By introducing sBTC, Stacks aims to overcome this challenge, enabling programmable Bitcoin transactions that can be used within dApps without compromising the core principles of Bitcoin’s decentralized design.
Stacks’ vision for sBTC is to create an alternative to the existing forms of wrapped Bitcoin, such as wBTC and cbBTC, which allow Bitcoin to be utilized in decentralized applications by essentially "wrapping" BTC into a form that can be transferred and traded on other blockchains. These existing options, however, rely on centralized custodians—third parties that hold and manage the underlying BTC on behalf of users. In contrast, sBTC introduces a decentralized approach, featuring a unique two-way peg mechanism that allows users to send and redeem sBTC on the Bitcoin network in a manner that remains aligned with Bitcoin's decentralized philosophy.
The team behind Stacks has taken pains to ensure that sBTC’s two-way peg system is as decentralized as possible. According to the project’s whitepaper, wBTC is “entrusted to a single custodian and hence antithetical to Bitcoin’s ethos.” While wBTC’s custodianship structure has evolved since the whitepaper’s publication, the contrast between a single custodian and Stacks’ decentralized model remains clear. Instead of relying on a single entity, sBTC will be maintained by a permissionless, decentralized network of participants, each with an economic incentive to uphold the integrity of the peg and operate it correctly.
Ali sees sBTC as just one example of how Bitcoin’s functionality can be expanded through Layer-2 solutions—blockchains built on top of the Bitcoin network that enhance its capabilities without altering its core structure. In an interview earlier this year, he commented, “Bitcoin rails can be upgraded through Layer-2s... There can be all sorts of use cases deployed there, and the capital can be more productive—it will make Bitcoin more valuable.”
