The emerging Eth2 virtual currency is making news with its coming upgrades that improve the scalability, security, and sustainability of Ethereum. Those upgrades include moving the consensus mechanism from proof-of-work (PoW). to proof-of-stake (PoS). PoS will drastically reduce the amount of energy necessary for mining blocks.
Ethereum’s smart contract capabilities combined with the ease of validation and reduced energy requirements make it the prime candidate to take the role of World Reserve Currency.
