Ethereum Medall Testnet Launch Hits Block Finality Issue


Ethereum Medella Testnet launched, but has not yet achieved the required participation.

The launch of the Ethereum Medalla testnet, which was scheduled for 13:00 UTC, did not go as smoothly as expected.

While the network launched successfully and proposed a sufficient number of blocks at the supposed genesis time, the participation rate was only 57%; much lower than the expected 80%.

This means that only 57% of the shares are used to validate the network. This presents a significant problem because the finality block cannot be reached until the network begins to bypass validators that are offline. Finality means that the block history is set in stone, which is equivalent to the block confirmation threshold at Et 1.0.

According to the developer, this may be because many validators who register by depositing 32 ETH are not running the validator software.

However, issues with Nimbus and Lodestar clients may account for about 10% of the participation gap, said Danny Ryan of the Ethereum Foundation.

The network is expected to resolve the issue on its own as the inactive validator is issued, but it may take at least a few hours to restore finality.

Meanwhile, the developer is investigating the issue with the client.
