Danny Ryan, one of the most influential contributors to the Ethereum (ETH) 2.0 progress, has written a longread to outline all of the milestones achieved by ETH2 so far - and all points of its further agenda.
Ethereum 2.0 is still Ethereum
The text covers all of the aspects of the development progress made by Ethereum 2.0 and all of the challenges it faces. First of all, Mr. Ryan emphasized that Ethereum (ETH) 2.0 is built on Ethereum, thus, traces its history back to 2014.

Mr. Ryan highlighted the nature of every stage of the Ethereum (ETH) 2.0 roll-out. Phase 0 or Beacon Chain will build the infrastructure for numerous validators. Phase 1 will be responsible for sharding design. The whole ETH1 network will be integrated into it as a single shard during Phase 1.5. Phase 2 will finalize the update of the Ethereum state. However, Mr.Ryan admitted that at the moment it is still a 'hot bed of research and prototyping'.
Each stage of ETH2 creation brings a plethora of opportunities to Ethereum (ETH) enthusiasts. Mr. Ryan is inviting all of them to participate in the staking process and to test the network performance in stages 1 and 1.5.
A large number of validators and shards, as well as a broad diversity of clients, reveal big challenges for ETH2 development, but this sophisticated environment guarantees technical advance and an unmatched level of decentralization.
Where are we now?
Mr. Ryan has also reviewed all of the active infrastructure associated with Ethereum (ETH) 2.0 right now. Firstly, it is a wide range of clients, namely cortex, lighthouse, lodestar, nimbus, pryzm, teku, and trinity. Mr. Ryan strongly recommended trying multiple clients, especially - the minor implementations.
Regarding the topic of testnets, Mr. Ryan mentioned the operations of the Witti multi-client testnet running v0.11 specifications. As U.Today Crypto News previously reported, this testnet was launched by Afri Shoedon shortly after the previous Schlesi testnet environment forked.
Furthermore, Mr. Ryan revealed the rest of the Ethereum (ETH) 2.0 instruments released so far: network tools, API schemes, keystores, wallets and slashing detectors.
In conclusion, he emphasized the huge progress behind the ETH2 team and community. According to Mr. Ryan:
The path we’ve chosen is difficult, but immense progress has and continues to be made.The core of this new mechanism is just around the corner.
