The Ethereum network has been working for years to transition from its energy-intensive proof-of-work blockchain to a more efficient proof-of-stake system, and its developers have now proposed a timetable for the transition. It’s not final yet, but during a call broadcast on the Ethereum Foundation’s YouTube page, they agreed to submit this pull request proposing to make the change when the network hits a certain difficulty level, which should happen on September 15th or 16th.
Terminal Total Difficulty (TTD) indicates the mining of a certain block at 58750000000000000000000 where the old network finishes and the new one starts.
