my relay #orly has a blossom server built into it now. the library has the fastest event codecs for both the database binary version and the json, i just finished adding a feature where it can now load the libsecp256k1 library as a dynamic linkable without the cgo complications (you just need a version of the library with schnorrsig extension on). it doesn't have negentropy but i have built a sync protocol that lets you build a cluster that stays in sync, and using the new policy engine you can specialise nodes to only replicate some specific criteria of events. i probably should put negentropy in there. easy enough to copy it out of khatru.
