cloudflare is decentralised?
1. Best production ready implementation is probably: https://github.com/lovvtide/satellite-cdn
2. Reference implementation by hzrd194: https://github.com/hzrd149/blossom-server
3. My proof of concept that runs on CloudFlare Free tier for personal use: https://git.v0l.io/florian/cf-worker-blossom-server

NO it's very much centralized but it is my personal server.
Having multiple different storage locations makes it decentralized.
And building tools to move / distribute your data.
