Or to make my question more precise : would the gossip model be used only for data distribution and we would still have to register on a node, or would it allow to keep and reuse our data and identity should our usual node disappear?
the idea is to move the key that AP uses to sign JSON-LD objects to the client and do all of the crypto operations there.
a server in this model is an always-on relay for replicating data. you can submit a message to any relay and expect to have it show up on all interested servers.
unfortunately, this will also break compat with HTTP/DNS-based AP servers, but hopefully this is something that the maintainers will be open to supporting.
