Not sure if the crypto thing makes it still interesting, but the decentralized idea behing IPFS decentralized storage had interest.
They have storage service thing that support HTTP api calls (POST; to store data, GET, to get a stored CID).
We added basic support for ipfs: scheme protocol, and the &ipfs <CID> build pattern could maybe explore:
+ipfs <URL_or_data>
>ipfs <CID>
+ipfs <DATA> | >ipfs <$1> | +qr-code
