[Feature Request]: Make it optional to use genesis hash and p2p network #4485
Description
Implementation ideas
Consensus nodes are expected to be run alongside bridge nodes by the same node operator and can thus be trusted by default. To make it simpler to get started, a bridge node should only need to specify the core ip that it's connected to. It should use the status endpoint to get the earliest height, latest height and chain-id. It should then start syncing from the estimated pruning height to the latest off the consensus node.
Node operators may optionally provide a trusted block hash (renamed from genesis hash) and chain ID, that the bridge node will use to start syncing from a specific block and will verify the block hash from the consensus node.
