According to Techub News, the Stacks Foundation tweeted that the code writing for the Nakamoto upgrade has been completed ahead of schedule (originally scheduled to be completed on July 15), and is currently undergoing internal and external audits, testing, and bug fixes.

Stacks said that the Nakamoto upgrade will shorten the time required to complete transactions to 5 to 10 seconds, making the transaction completion speed about 100 times faster than the current speed.
