Editing Nexus P2P trust network (section)

=== Will there be redundant copies on different machines, or will each profile live on one machine? ===
There will be redundant copies of all nexus records, probably about 20 live (online) copies. No profile information is stored. If the owner of a nexus identity record wants to change the link to his profile, he must create a new identity record. All records on nexus have an expiration date. So two competing records referring to the same identity are resolved by the most recent update. It is up to the owner of an identity to periodically refresh or update his identity and the references he creates. He can specify the lifetime of his records, but there would be a system-wide maximum time limit.
