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