UPDATE: Buterin clarified that the network will not be launched in July. The launch of Ethereum 2.0 is still scheduled on the end of 2020.
Yeah I did not say July. Perhaps the question contained the word July but I did not hear July when it was asked.— vitalik.eth (@VitalikButerin) May 12, 2020
Vitalik Buterin said during CoinDesk’s Consensus: Distributed conference the transition of the Ethereum ecosystem to ETH 2.0 is scheduled for July 30, TheBlock has reported.
The Schlesi network currently has two clients: Lighthouse from Sigma Prime and Prysm from Prysmatic Labs. The Teku and Nimbus clients have also synchronized with Schlesi and will soon launch their own validators on the testnet.
According to the roadmap, with the arrival of Ethereum 2.0 the following aspects will be redefined: gas calculations, principles of customer synchronization and changes in fees. The change to proof-of-stake will increase the bandwidth of the network.
Even though the launch of the Ethereum 2.0 was originally scheduled for January 3, it has been put off several times.
Ethereum 2.0 developers rolled out in late April a testnet with support for multiple customers. According to the description on GitHub:
"Before such a mainnet can be launched, we need testnets that mimic mainnet conditions as good as possible. This requires us to have stable, long-term, and persistent testnets up and running that are supported by not only one client but multiple clients, ideally, all clients. The Schlesi testnet is one of many steps in that direction." Participants in this testnet will not receive real rewards, however, the network is not a simulation, but a complete testnet for the end user with a "slightly modified mainnet configuration."
Anyone can join the network as a validator or node in order to experiment with the mechanisms that will later be launched in the Beacon Chain of the ETH 2.0.
