Odaily Planet Daily News Bitcoin L2 network Stacks began an upgrade called "Nakamoto", which started at Bitcoin block height 840,360 and aims to solve network congestion problems. Network creator Muneeb Ali said that Stacks' original design produced blocks at the same speed as Bitcoin, which led to congestion problems. This upgrade will separate Stacks' block production schedule from Bitcoin's. "Nakamoto" will introduce a new way of producing Stacks blocks and update its unique proof-of-transfer consensus algorithm. The upgrade will be fully activated in May.
