Ethereum 2, also known as ETH2 or Ethereum 2.0, is a proposed upgrade to the Ethereum network.
ETH2 is a proof-of-stake (PoS) system that is intended to address some of the key issues with the current proof-of-work (PoW) system, including scalability, security, and energy efficiency.
The PoW system used by Ethereum today is the same system that is used by Bitcoin. It is a resource-intensive system that relies on miners to validate transactions and add blocks to the blockchain.
This has led to concerns about centralization, as a small number of miners control a large portion of the network’s hash power.
ETH2 is designed to address these concerns by moving to a PoS system. Under this system,validators will stake their ETH on the network in order to validate transactions and add blocks to the blockchain.
This will require much less energy than the PoW system, as there will be no need for miners to run expensive hardware.
The move to ETH2 is not a simple one, and it will require a significant upgrade to the Ethereum network. This upgrade will be implemented in two phases.
The first phase, which is expected to launch in 2020, will focus on scaling the network. The second phase, which has no set launch date yet, will focus on adding sharding and other features that will further improve scalability.
ETH2 is an ambitious project that has the potential to improve upon the existing Ethereum network in a number of ways. However, it remains to be seen if it can live up to its promises.
Only time will tell if ETH2 is a new coin or simply an evolutionary step for Ethereum.
