Golden Finance reported that the Stacks Foundation, the foundation of Bitcoin L2 network Stacks, stated on the X platform that the code writing of Nakamoto has been completed ahead of schedule (July 15), and is currently undergoing internal and external audits, testing, and bug fixes. It is reported that the Nakamoto upgrade will separate the block production schedule of Stacks from that of Bitcoin, and will introduce a new Stacks block production method and update its transfer proof consensus algorithm. The Stacks Nakamoto upgrade will be able to achieve a transaction speed of about 5-10 seconds, which is about 100 times faster than the current transaction speed.
