Topaz, the first testnet with Eth2.0 Phase 0 mainnet configuration, has been released

Just two years ago, Prysmatic Labs began its journey to achieve Eth2.0, which has three milestones: Ruby, Sapphire and Diamond (1). These milestones reflect our vision of how to extend Ethereum to the global scale. We are proud to announce the final restart plan of the testnet for Eth2.0 stage 0: Topaz testnet .

Ruby, Sapphire, Topaz and Diamond milestones

The Topaz testnet is unique because it represents the complete Eth2.0 stage 0 mainnet configuration. In the previous Sapphire testnet, our goal was to reach the scale of the mainnet, but use a smaller 3.2 ETH as a collateral deposit. For the Topaz testnet, the verifier will have to mortgage 32 ETH on the Goerli Eth1 testnet to participate [Remark: The mortgaged ETH is the Goerli testnet token].

• The central bank's digital currency is ready: the wallet is undergoing internal testing, and related concept stocks have risen collectively
• The central bank's DC / EP beta is out, and we guessed about these functions …
• Observation | A picture to understand the Ministry of Industry and Information Technology's blockchain standard commission

Topaz testnet is now accepting Genesis mortgage deposits. Tomorrow (April 16), Prysmatic Labs will begin to close our Sapphire validators and start sending new genesis deposits. If you want to become a genesis validator, please send your mortgage deposit before UTC 00:00 on April 16, 2020 , because Prysmatic will start sending deposits on a large scale to start the Topaz test network. Now visit the testnet link (2) to learn more about becoming a Topaz verifier, please join us on the Discord channel!

Ethereum founder Vitalik Buterin also shared news about the Topaz testnet on Twitter and said that the testnet "may not be a 'multi-client testnet ' because we may restart one or two soon, so as to have More opportunities to test the genesis mechanism. But Prysmatic Labs still brought significant progress and great work. "
