Sajida Zouarhi, PM at Ethereum development studio ConsenSys, shared the details of the most eccentric Ethereum 2.0 testnet experiment so far. It is supported by seven Ethereum implementations!
When ETH1 meets ETH2: Introducing Steklo
According to Ms. Zouarhi, Ethereum (ETH) developers run a testnet environment that involves three Ethereum 1.0 clients (Besu, Geth and Nethermind) and four Ethereum 2.0 clients (Teku, Prysm, Lighthouse and Nimbus). This development testnet is dubbed "Steklo," which is Russian for "glass."
Seasoned Ethereum (ETH) researcher Diederik Loerakker (@protolambda) added that "new" Ethereum (ETH) clients will serve to ensure network consensus while "old" implementations should be referred to as "execution" implementations.
Developers will experiment with all 12 possible combinations between these implementations. One more specific of this testnet is its ultra-short lifespan. Steklo testnet will be alive for one day only, but developers have scheduled the next iterations.
The next "PoS testnets" will simulate the operations of proof of stake Ethereum (ETH) for much longer periods. Development efforts are coordinated in the "Rayonism" chat of Ethereum's R&D Discord room.
Ethereum (ETH) mining is on borrowed time
Also, the team working on Teku implementation by ConsenSys is working on bringing sharding to the Rayonism experiment.
As covered by U.Today previously, Ethereum (ETH) researchers indicated the most likely timeframe for the last days of Ethereum (ETH) proof of work (PoW) mining to come.
Tim Beiko and Trenton van Epps claim that miners should brace themselves for the "end of 2021" as a conservative date for the breaking even of mining profitability.
