Ahead of the upcoming Bellatrix upgrade for Ethereum scheduled today, over 73.5% of Ethereum nodes are now marked as “Merge ready.” This upgrade is the most critical step before the official Merge, that will see Ethereum network transition to a proof-of-stake consensus mechanism between Sept. 10-20. Moreover, node operators that don’t make the update before the Bellatrix upgrade will cause the Ethereum clients to “sync to the pre-fork blockchain.”
