Odaily News Bitcoin L2 network Stacks has started an upgrade called "Nakamoto" at Bitcoin block height 840,360, which aims to solve network congestion. 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.
