Ethereum announced successful implementation of Bellatrix upgrade on Beacon Chain
The Bellatrix upgrade is seen as one of the last necessary steps prior to the official Merge, which will see Ethereum transition to a proof-of-stake (PoS) consensus mechanism between Sept. 10-20.
After Bellatrix, the Merge is scheduled to take place in the so-called “Paris” upgrade. This is expected to take place between Sept 13th-15th.
