Network layer consists of a regular P2P network (does it?). Should we use membership/gossip for this too?

On top, data is distributed through a GOSSIP protocol like SWIM:

  • As soon as a new key (or new version) is pushed to a peer, the peer will gossip this key to the rest of the network.

  • As soon as a key should be removed, the delete action is pushed to a peer and will gossip to the network.

  • When a node does not have a certain key, it will ask the network for the key (also gossip?).

  • Could we fetch a subset of keys, like all keys starting with AF.+ for instance? (should be send in an archive, instead of single keys)

  • When a new node enters the network, how are the key distributed?

  • What if there are two keys with different data (which MAY happen when 2 users upload the same address). Does one "win", if so, which one?

  • Do all nodes have all keys? Is it possible to have nodes with a small subset of keys?
