Teku:Nethermind on gnosis: Nethermind returned twice the block for the same slot #7356

Open galaxy-mario opened 3 weeks ago

galaxy-mario commented 3 weeks ago

Description Nethermind returned a block from the same slot twice, with a 3s delay. Teku clearly knows/shows in logs the block is empty.

We are not sure if this is an issue on Teku or Nethermind, we'd like to understand what happened and whether there is anything that can be done to improve it.

Desktop (please complete the following information): Please provide the following information regarding your setup:

Additional context This is on the gnosis chain, where the time to get a block in is 1.66s max.
