And on Wednesday, it got some.Ethereum, the most popular crypto platform, appears to have successfully upgraded its software architecture from a type of blockchain known as “proof of work,” which it has run since its inception in 2015, to a type of blockchain known as “proof of stake.”This upgrade, which came to be called, simply, “the Merge,” is already being heralded as a watershed moment in the history of crypto.
