Script to run Nimbus-eth1 syncing to any of the networks that Geth supports
by name, connecting to a single dedicated peer for that network.
All protocols are disabled other than the minimum we need for block sync.
This is very helpful for debugging and improving pipelined sync, and for
improving the database and other processing, even though p2p sync is the
endgame.
- Discovery protocols are turned off
- NAT hole punching protocols are turned off
- Whisper protocol is turned off (`--protocols:eth`)
- The only connection is to a single, active Geth for that network.
- Each network's data is stored in a different location to avoid conflicts.
- Each network is accessed by binding to a different port locally,
so we can run several at the same time.
- Log level is set to `TRACE` because we can read them when we're not
swamped with discovery messages. Sync isn't fast enough yet.
