Blossom is a vastly inferior product to Arweave.

They both store files, like images, in a decentralized way.

The issue is images cost money to replicate and store.  Arweave solves this by programming the funds to only pay out after service.  While Blossom uses Nostr key pairs and expects users to use Bitcoin.

But bitcoin has no binding contract.  Therefore, Blossom is:

---Not trustless
You trust the relay won't just steal your bitcoin.

---Not as decentralized
If you can't trust the server you're paying, people will naturally gravitate to trusted nodes

---Blossom is more censored.
With Arweave you get the whole network instantly and trustlessly, but with Blossom you only get the few relays you trust to pay or host on.

---Less end-user freedom
The viewer of Blossom content is forced to pick from the poster's relays.  While on Arweave, the end user picks from the entire network and can even self-host where they get content.

---Arweave is far more private.
Blossom forces you to tell many servers your IP and npub.  With Arweave, the single gateway you choose or self-host knows your IP.  In fact, similar to Tor, your VPN doesn't even know what content you're looking at because ALL content shares the same gateway IP.

---Arweave does entire websites
Blossom isn't designed for whole sites, it's for a jpeg meme on Nostr.  While Arweave not only does whole websites, but even it's own DNS system that already works without new software.  Arweave + a Nostr client would be a game-changer for images, podcasts, and even video.  

My point:
You can use Blossom if you want, I'd even subscribe if my client supports it.  I'm happy to see development, and I want you guys to succeed.  Just don't be closed off to other solutions... because ironically that's the very censorship you wish to defeat.
