Ethereum 2.0, or Ethereum upgrades as it is formerly known, is the initiative to make the world’s second-largest cryptocurrency by market cap more scalable, sustainable, and secure. The Ethereum upgrades will transition the blockchain from a proof of work consensus mechanism to a proof of stake model.
Ethereum 2.0 will consist of a set of upgrades implemented in parallel to make the leading platform for decentralized applications (dApps) far more efficient. ETH2 is the term used to distinguish the new version of Ethereum’s native cryptocurrency from the current ETH1, which operates on the older network.
Ethereum 2 is being developed on The Beacon Chain, an independent network, even as the current Ethereum network continues to function. The next stage, known as The Merge, will fuse the Beacon Chain into the Ethereum mainnet. To distinguish between the Beacon Chain and Ethereum mainnet, developers use the terms ETH2 and ETH1.
The Ethereum team is phasing out the use of ETH2 or Ethereum 2.0 following The Merge. The process will bring together both ecosystems into a single blockchain, instead of having Ethereum 1 (proof of work) function alongside Ethereum 2 (proof of stake).
