contenthash has been coded as uvarint(proto) + payload... so shouldn’t this convention be followed?
0xE3 = ipfs
0xE4 = swarm
0xE5 = ipns
I guess defining proto 0x64 (d) as a DataURL would work as-is, but it wouldn’t have a known length so it’s not embeddable without an external wrapper (although I guess that’s not a requirement of multicodec.)
The following would avoid the base64 overhead:
uvarint(0xDD)
+ uvarint(len(mime)) + mime utf8 bytes // eg. "text/html"
+ uvarint(len(payload)) + payload bytes
Although for simplicity, I’m a fan of bypassing the multicodec stuff (as long as the first uvarint decodes correctly) and just embedding raw utf-8 data.
Should it also support URLs for 30X redirection?
uvarint(0xDD) + uvarint(0/*url*/) + uvarint(19) + "https://ens.domains"
