I saw your update on that earlier, nice :) it's also getting into NDK as well I worked out a simple client implementation previous week on with the blossom-client-sdk here https://nuxstr.nostrver.se/blossom with a blossom-server to test things out. And today I set up a new mediaserver here https://nosto.re/ and getting my head around for a discovery relay for just 10063 kind events for now (just like the 10002 kind events but then for your blobs) on relay.nosto.re
