"This important release focuses on integrating the IETF BLS standard into the eth2 specification."
"This release also includes a profound and urgent reorganization of files / directories …
The remaining changes are some minor optimizations and cleanups. Most of these are usually backward compatible and all integrations should be very simple.
The v0.10.0 release aims to determine a stable target for multi-client testnet and phase 0 of the security review. We expect some revisions in February / March based on the results of each phase. "
Ben Edgington, developer of PegaSys, one of the Ethereum 2.0 clients, clarified that the version "plans as a frozen version as the basis for testnet and audit work."
In addition to the review of the Beacon chain code, the review of the Ethereum 2.0 deposit contract is in progress. Before planning to launch a multi-client test network, the Ethereum 2.0 client has been waiting for the release of this version.
Although the changes announced in this final specification release are about the signing standard, the Beacon chain design itself announced some changes at the end of last year and it is now complete.
However, for these changes, it is unclear how much the Ethereum 2.0 client has been merged, and some major changes must be restarted on their client-specific testnet to complete.
However, the final version of the Ethereum 2.0 specification version 0.1 is a key step towards a full release, and coders and everyone else are now waiting for an audit report, which may require some further changes.
"There are 13,000 validators waiting in line to enter the Prysm test network. The new validators initially entered the network at a maximum of 4 times per period, so according to my calculations, this is two weeks of congestion!"
Some of these testnets have now been upgraded to the mainnet configuration and there are many potential stakers, so all seem to be tested.
It is expected that they will run in this state for a while while waiting for review, and launching a multi-client testnet is a key indicator.
Previously, Justin Drake, an ethics researcher at the Ethereum Foundation, had set the unofficial deadline for the Ethereum 2.0 founding block to be July 30.
This timetable seems to be based on reasonable estimates, as the multi-client testnet requires approximately three months of smooth operation.
If this testnet is released this winter and all goes well, then PoS blockchain may be released in late spring or early summer or after half of Bitcoin.
