Opening here for visibility

With optional execution proofs, certain nodes will no longer need an EL. They will instead receive proofs over a subnet and that serves as a replacement for validating the execution payload.

Current hacks

When I refresh Dora, it randomly chooses a node from the kurtosis config. However, since "normal nodes" won't necesarily have proofs, I added a hack to allow me to select a specific node each time Dora is refreshed. In the Kurtosis config, I add a "Index" lets say 3, then while setting up Dora, it only keeps the node at index 3.

Another way would be to pass a beacon chain end point, and have that overwrite the other beacon chain endpoints.

Hack that we use to fix the node we want to always connect to.

Note: The alternative here would be to not put Dora in the kurtosis config and just running it separately connecting to the specific node we care about.
