Here is the main discussion about the current (hopefully very temporary on the scale of the currency), but it is… in French:
What @cgeek is saying is basically:
-right now, people who use the main cesium node on duniter.fr are all blocked because they are all trying to register on the same node, which is already full and won’t accept any new identities,
-one solution is to set up your own node, and register from there, since a node always accepts its own documents,
-from there the node can propagate the identity to other nodes.
This is an interesting proposal, that is somehow similar to another recent proposal to give a “trust level” during certifications (again, a thread in French, sorry!), which was rejected since “a percentage of trust” would totally be relative from one person to the other. Another problem is that it would make the system more complex while not really bringing much additional value, and one additional drawback I see with your proposal is that it would make a de facto hierarchy in the WOT, which I believe is not wanted in the philosophy of the project. Everyone can be a member (as soon as they get enough certifications) and every member is equal in the system.
