ETH 2.0 is THE big, very big and major evolution expected by the entire cryptocurrency ecosystem. The Ethereum teams, led by Vitalik Buterin, the founder, have been working on improving their blockchain for several years.
Today, the ERC20 blockchain (therefore ether) is widely used but it is still expensive in terms of fees, energy-intensive and limited in number of transactions.
For example, the Visa bank card network performs 1736 transactions per second, the Bitcoin network will perform 4 per second. The update with the release of ETH 2.0 will literally revolutionize all of this: 90% less costs, 10 times faster and 90% less polluting and energy-consuming. In short, paradise.
Although we do not yet know precisely when the release of ETH 2.0 is planned, we do know that the first update of ETH 2.0 should take place during the spring of 2022 and phase 2, heralding the final release of the evolution is expected at the end of 2022, provided that they do not experience further delays.
It should also be noted that to date the Ethereum blockchain hosts a large part of the smart contracts (or smart contracts) which represents one of the most important functionalities of Ethereum and whose applications are infinite. An example of a smart contract project: imagine that you do without an intermediary (such as AirBnB) to make seasonal rentals and that all exchanges are done from person to person. This may be possible one day thanks to a smart contract.
