Ethereum’s developers have officially confirmed September 6 as the date for Ethereum’s long-anticipated transition from proof of work to proof of stake, known as The Merge.

“Following years of hard work, Ethereum’s proof-of-stake upgrade is finally here!” the Ethereum Foundation wrote in a blog post on Wednesday. “The successful upgrade of all public testnets is now complete, and The Merge has been scheduled for the Ethereum mainnet.”

The Merge will be split into two upgrades, called Bellatrix and Paris. Bellatrix is timed to occur at 11:34 AM UTC on September 6 and Paris will be triggered sometime between September 10 and September 20, according to the blog post, which provided the image below.
