According to an “Eth 2.0 Research Team AMA” that took place on Reddit last Thursday (February 6), which involved Ethereum Foundation’s Danny Ryan and Justin Drake, the team says that it is “unlikely” that ETH 2.0 will launch in Q1 or Q2 of 2020, but is “hoping” for launch by 30 July 2020, and extremely confident of the launch happening before the end of the year.
When asked about the expected launch date for phase 0 of ETH 2.0, Drake said:
I'm hoping we can launch by July 30, 2020 (the 5th anniversary of Ethereum 1.0). I think it's unlikely we will launch in Q1 or Q2 2020 especially if we want three clients to be production ready for launch.
He was then asked if he would consider it a failure if the launch of phase 0 did not happen in 2020:
“Yes, it would be a failure. I have 95% confidence we will launch in 2020 :)”
Ryan seemed even more confident about the launch of phase 0 in 2020:
“Phase 0 will certainly launch in 2020. Audits are out and testnets are getting stronger every week. Estimates depend on both the spec and clients getting (relatively) clean bills of health in 3rd party audits. The rest depends engineering concerns and stablizing/optimizing in this last mile of work.
“I don’t see a reality in which Phase 0 does not launch in 2020.”
