Ethereum 2.0 will be launched on July 30, 2020, but that's not for sure ...
Because so far we have only the confidence of Vitalik Buterin, but there is still no finished product.
At the moment, it is known that the deposit contract for the Ethereum blockchain has been audited and now it will be at least six weeks at the public testing stage. After its completion, the contract can be launched and this will be the official start of the migration of ether to the platform version two point zero. This contract will allow you to block funds on the air in the current network and transfer their counterpart to the new blockchain using the Proof-of-Stake algorithm.
In addition, Vitalik Buterin and other Ethereum developers are confident that this year they will officially launch the zero phase of the updated platform. We are talking about the so-called Beacon Chain, which is already 99% ready and now they want to finally run it in the test version for at least 8 weeks and provided all three of Ethereum's main clients work.
Beacon Chain hides the most important element of the future platform, because it will be responsible for coordinating the work between the current and new blockchains, as well as appoint validators, determine the creator of the next block and ensure that all network participants act within the rules.
The Beacon Chain launch event is likely to be timed to July 30, 2020, when Ethereum will celebrate its fifth birthday. If this is so, then the holiday can be grandiose and ether coins will please us with an increase in value. As usual, I’ll insert my five cents that switching to the POS algorithm will not solve the problem of the lack of a product for the mass consumer. But at least it will remove questions about cheaper and faster transactions, like EOS or TRON, and there is also Cardano on the way.
