optional node certification process / trust scores

[maxtheaxe]

• combine function of vaxport to create some sort of optional verification process for "legit" nodes down the line
• some node (or user?) with some higher level of trust signs off on public keys to sort of "vouch" for that node
• some options (more exploration needed):
• networks of sorts could be run by community leaders
• maybe user clients that successfully exchange messages automatically sign off on the key of each node to build a trust score of sorts
• users could set threshold for minimum trust score
• this verification would have to occur clientside to avoid faking
• would then need to have users check duplication of keys across nodes
• could allow either node key duplication or subkeys to show ownership of nodes, would just track trust score across a given network (though bad actors could potentially drown out poor reputation by gaming the system in any number of ways)
• lots more thought clearly needed, just thinking out loud here
