BlockBeats news, ethereum founder Vitalik Buterin also Shared on Twitter the latest news on Topaz, the first test site with an Eth2.0 master configuration. Vitalik says that the test network "may not be a multi-client test network yet," because it will probably be a reboot or two soon to give you more opportunities to test the creation mechanism.
According to Unitimes, two years ago, Prysmatic Labs began a journey to implement Eth2.0 with three milestones: Ruby, Sapphire, and Diamond (1). Now the final restart plan for the test network for Eth2.0 phase 0: Topaz test network.

Ruby, Sapphire, Topaz and Diamond milestones
The Topaz test network is unique because it represents the complete master network configuration for phase Eth2.0 0. The goal in the previous Sapphire test network was to reach the primary network size, but to use the smaller 3.2 ETH as collateral for deposits. As for & have spent Topaz test network, verifier will have to test online mortgage 32 ETH at Goerli Eth1 to participate & NBSP; & have spent Note: mortgage ETH is Goerli test net token.
Topaz test is now accepting genesis mortgage deposits. Tomorrow, Prysmatic Labs will begin shutting down Sapphire verifiers and sending new genesis deposits. If you want to be a genesis validator, send your mortgage deposit before April 16, 2020 at UTC 00:00, when Prysmatic will start sending deposits in large Numbers to launch the Topaz test network.
