Last Wednesday, the developers of Eth 2.0 -- along with Ethereum co-founder Vitalik Buterin and Eth 2.0 researchers Danny Ryan and Justin Drake -- ran an AMA on Reddit in which they stated their plans for the launch of the new blockchain. The team said the new network won’t be ready until three clients can run stable testnets for a period of eight weeks.
Initially, the launch was scheduled for January 2020, but then got pushed to a Q2 window. Now, The team is eyeing for a July release, in time for the network's fifth anniversary.
Danny Ryan commented the following in the AMA thread: “Phase 0 will certainly launch in 2020. Audits are out and testnets are getting stronger every week,” later continuing with “I don't see a reality in which Phase 0 does not launch in 2020.”
Ryan later went on to state that Phase 0 and 1 are basically 99 and 90 percent complete, respectively. The latter phase will link ETH holders with staked assets to the Beacon Chain, which is the brand-new Proof-of-Stake blockchain.
