Ethereum 2.0 developers will run yet another testnet "Zinken" in the coming days as the Spadina testnet didn't go smoothly enough.
Danny Ryan, a core Ethereum developer, said Spadina suffered long waits to block finality and low participation from Ethereum 2.0 clients, or parties that run nodes to validate transactions.
"Even though we expect moderately low participation on a short-lived non-incentivized testnet, small errors in the client release process great[ly] exacerbated this problem, resulting in ~1/3 participation in the first few epochs," said Ryan. "In response to these issues, we'll be hosting -at least- one more dress rehearsal -- Zinken -- prior to genesis."
Prysmatic Labs, one of the Ethereum 2.0 clients, said the issues with the Spadina testnet gave a "bad look for this 'genesis rehearsal.'" However, it wasn't a critical bug or a consensus error, "but rather something due to configuration parameters which can be fixed with a release," said Prysmatic.
The Zinken testnet is expected to run "in a week and a half," said Ryan.
