Problem description
As Ethereum moves towards a world where historical information over 1 year is purged on nodes that don't really need it, support has been gaining around ERA files
.e2s
to store and redistribute execution, but also beacon chain history and state. We should be able to support integrating this data structure format in Lodestar.Solution description
The solution is not as straight forward, but we can work towards how we can approach supporting these files.
As of today, no specification has been proposed about how to integrate an endpoint for supporting this feature.
