Elon Musk is rumored to have added a huge stake in Ethereum as Ethereum 2.0 is slated to be released on September 19th. This upgrade is also known as Eth2 and Serenity. This will not just make the blockchain more secure, but the biggest complaint has been the high fees, and energy consumption, which will be dramatically reduced. This upgrade, which Musk has deemed a game-changer, will allow a much-needed shift from the energy-hungry proof-of-work (POW) we currently have to the greener, energy-efficient proof-of-stake mechanism (POS).
