Following the Spadina testnet failure at the end of September, the Ethereum 2.0 Phase 0 rollout looked in serious jeopardy.
Billed as a dress rehearsal for ETH 2.0 genesis, core developer Danny Ryan reported several issues with the Spadina run. The most pressing problem was the long wait times for transactions to become irreversible.
Ryan attributed many of the issues to the low participation rates, which is expected in an uncentivized testnet. He also brought up the poor client distribution, which saw the majority of participants opt for using the Prysm client.
Today we launched, Spadina, a dress rehearsal for eth2 genesis.
Although the eth2 clients have generally become quite robust, the long wait for finality today highlighted issues closer to the edge of the stack — cli options, testnet config, bootnodes, genesis calculation bugs

In response, Ryan announced another dress rehearsal testnet, named Zinken, to reassess the situation.
