P2P: validator mode #865
Description
- no incoming connections - only via VPN.
- Is this just done by setting p2p.laddr in config?
- This can be modeled and tested using AWS or GCP VPC functionality.
- some sentry manager that determines connectivity to sentries.
- for instance slowly shuffle so we're connected to a random 4 of 7 or so at a time
- should this be a separate process? we can have a default that just dials all the addresses given in a config, but allow specifying the address of a sentry-manager-proxy that ensures there's a cluster of sentries available and tells you which ones to connect to
