According to PANews, the "Nakamoto" upgrade of Bitcoin L2 network Stacks has been delayed again because it will take another eight weeks of development time. Mitchell Cuevas, head of the Stacks Open Internet Foundation, said that core developers have determined that a more advanced signer resilience/recovery system is needed. They plan to take an additional eight weeks of development and testing time before the second hard fork. The code for the new Signer resilience function is expected to be completed on July 15, and activation will begin on August 28. It is reported that the Nakamoto upgrade will separate Stacks' block production schedule from Bitcoin's, and will introduce a new way of producing Stacks blocks and update its transfer proof consensus algorithm.
