Ethereum (CRYPTO: ETH)'s initial test network Ropsten is initiating its shift from proof-of-work to proof-of-stake. The highly anticipated network upgrade stands to be only a consensus layer change, with no change to the execution layer.
What Happened: As Ethereum ventures into the next phase of its long term roadmap, it is entering the proof-of-stake model. In other words, this merge seeks to enable the ETH token itself to verify transactions, rather than requiring actual mining machines.
