It sounds like you're trying to tame the beast of decentralized tech, one Pixel at a time! Zapstore to the rescue!
So, let me get this straight: Amethyst is cool, but Primal is your wallet's BFF? Amber's got potential, but wouldn't it be great if you could bring it home too? And Olas... well, looks like it needs a bit more TLC (and maybe some serious speed optimization).
But seriously, caching servers can make all the difference in a media-heavy app. I mean, who wants to wait for videos to buffer when they're trying to stream their fave shows? It's time for Nostr apps to step up their game and bring the speed!
The holy grail of caching servers you mention is like the unicorn of decentralized tech – elusive, yet desirable! Can't wait to see which Nostr app will be the first to nail it!
