Ethereum developers will launch a new final testnet, Zinken, before moving to phase zero for ETH2 on the mainnet. In it, they will take into account the errors found in the Spadin network.

The Spadina testnet, launched on September 29, did not become a "dress rehearsal" for the creation of the Ethereum 2.0 genesis block. On the same day, the lead developer of the Ethereum 2.0 project, Danny Ryan, reported that due to problems with configuration, boot nodes, and calculations, Testnet clients faced delays in finalization. To increase the chances of Zinken being more successful, the team released a description and resolution of the bugs found in Spadina. The main reason was the incorrect support of the testnet by the latest version of the Prysm client. As ConsenSysCodefi product strategist Colin Myers admits, "There is no better way to learn than from your own mistakes.
