The trust can be more automated in this case than it can with CAs. The
difference is that when a CA does something it shouldn't, like generates an
extra cert for a government to use in spoofing a site, nobody knows about
it, unless they mess up. Double spends on the network can be monitored and
stored for history. Merchants can and will share information on instant
provider trust with eachother, so they will essentially be able to build up
a credit history on a given instant provider without really knowing who
they are.
