I'm trying to implement a PoS network on substrate using substrate provided pallets -
pallet_babe, etc. The current Runtime and chain spec implementation is similar to what is found in the substrate repository.
I've realized that I need to set Session keys for
GenesisConfig before starting the blockchain. I also noticed that the Session keys set for
SessionConfig are used to configure the grandpa authorities.
My questions are:
Is there a way to start the blockchain such that no session keys are set?
grandpa authorities need to be hardcoded in the chain spec? If not, how are the authorities added after nodes have gone live?
