What Are the Latest Changes in Ethereum 2.0?

Ethereum 2.0 is an upgrade to the Ethereum network, expected to be implemented at the end of 2020. Once launched, Ethereum 2.0 will become a testnet for the Proof-of-Stake (PoS) consensus algorithm system. Most economic activities and smart contracts will continue to run on the original Ethereum network, which will continue to be a parallel system to Ethereum 2.0. Developers have implemented the connection bridge for the Eth1 to Eth2 transition, but reverse transfer of tokens is not possible.
