Encyclopedia is "general education", referring to its broad scope. Wikipedia added wiki as a reference to the source, so the best one would be {source}pedia.

Fedepedia isn't awful but feels... bland, in my opinion.

Something like consolidate is a good synonym for it, but consolipedia also doesn't feel right to me, so if we're not referring to the federated part, we'd have to refer to the decentralized part. Decentropedia is fairly decent, but I'm fond of Micropedia, because the root word is very common, and I feel it's catchier than decentropedia. Either of those are good though.
