Ethereum 2.0 Developers to Launch Zinken Testnet After Spadina ‘Dress Rehearsal’ Fails


After five years of waiting for Ethereum 2.0, developers may have to wait longer for its launch after a failed launch of the Spadina Network. The ETH 2.0 developers plan a third testnet, Zinken, which is expected to solve bugs and fix problems found in the previous two testnets – Spadina and Medalla.

ETH 2.0 is expected to introduce sharding protocols to increase Ethereum’s scalability and reduce blockchain gas costs. The main upgrade on ETH 2.0, however, is the proof-of-stake (PoS) consensus mechanism that is expected to replace the energy-intensive proof-of-work (PoW) currently available.

ETH 2.0 Phase 0, or the Beacon Chain, is expected to launch later in the year with the full implementation of the upgrade set to take over two years. According to original plans, Spadina was set to be one of the final testnets, or a “dress rehearsal, before the launch of Phase 0, but bugs and finality problems were discovered.”

One ETH 2.0 developer, Danny Ryan, wrote on Twitter that despite ETH 2.0 clients becoming more robust, the high latency times for finality raised several issues on the Spadina network, including “cli options, testnet config, bootnodes, and genesis calculation bugs.” Ryan further wrote,

“Even though we expect moderately low participation on a short-lived non-incentivized testnet, small errors in the client release process greatly exacerbated this problem, resulting in ~1/3 participation in the first few epochs.”

To respond to the issues stated above, the developers will run the Zinken testnet as a “dress rehearsal.”

The bugs, however, are not critical, Prysmatic Labs developer, Raul Jordan, stated. Comparing the failures in Spadina to Medalla’s earlier failures, Jordan believes the failures will be a “learning experience” for ETH 2.0 developers.

Ryan confirmed the Zinken testnet dress rehearsal would be launched in the coming two weeks.
