On January 10, according to official news, the Bitcoin Layer2 network Stacks has completed a 500% upgrade to expand network bandwidth and has been launched on the mainnet. Core developers plan to continue several other optimizations in 2025. It was previously reported that on October 29, Stacks' Nakamoto upgrade was successfully launched, introducing "Fast Blocks" and "Bitcoin Finality" mechanisms to increase transaction speed. After the Nakamoto upgrade, Stacks block production will be independent of Bitcoin block production, and user transactions can be confirmed within seconds.
