The rest clicks pretty well in my mind.
The answer to that, that comes to mind, is that "crowd" conveys that the ledger is public, out there, and collectively maintained by everybody. When you say "peer", I think of two people of the same approximate age and social status. When you say "relay", I am thinking of relay races, or delivering messages or things.
Exactly. ;p But in my mind, 'crowd' makes me visualize random people, maybe ones I don't trust. Where as 'peer', as you say makes you think of people of the same age, social status, in my mind, people 'like me'. It makes it seem mroe trustworthy. And with relay, thats exactly what we are doing, delivering messages to the ledger. =)
