PANews reported on October 18 that Stacks announced that it would conduct a major upgrade at Bitcoin block height 867867 (about October 29), called the Nakamoto upgrade. This upgrade will introduce "Fast Blocks" and "Bitcoin Finality" mechanisms, aiming to significantly increase transaction speeds and make Stacks the preferred platform for building a scalable Bitcoin ecosystem.

After the Nakamoto upgrade, Stacks block production will be independent of Bitcoin block production, and user transactions can be confirmed within seconds. At the same time, through Bitcoin finality, the security of Stacks transactions will be consistent with Bitcoin and will no longer be independently forked. In addition, the core development team will launch sBTC this year. This decentralized solution will support the seamless transfer of Bitcoin between L1 and Stacks L2, further promoting the expansion of the Bitcoin ecosystem and the development of decentralized applications.
