The Nakamoto upgrade of Stacks introduces the "Fast Blocks" and "Bitcoin Finality" mechanisms

On October 29th, Muneeb Ali, the co-founder of Bitcoin Layer2 network Stacks, announced on platform X that the Nakamoto upgrade for Stacks has been successfully launched. With this upgrade, the finality of Bitcoin transactions on Stacks Layer2 reaches 100%, and transaction ordering and reversal are protected by all of Bitcoin's hash power; "Fast Blocks" will reduce delay to a few seconds instead of Bitcoin's 10-40 minutes; Stacks will no longer fork with Bitcoin, and the only way to fork Stacks L2 is to reorganize Bitcoin itself; The Nakamoto upgrade lays the foundation for SBTC launch which is expected within 4-6 weeks from now. Core developers have released this version focusing on network security and carried out large-scale upgrades. In the coming weeks, more optimization measures targeting network bandwidth and latency will be rolled out; these upgrades are not consensus critical upgrades but regular node upgrades.
