However, the default must be binary. - although the above are useful for web servers, they are also useful elsewhere and I intend to use them in NFC (NDEF records) where a shorter length is critical. - I have no idea how easily IANA will accept these proposals. - current approved mime types: https://www.iana.org/assignments/media-types/media-types.xhtml Thoughts? --- @DocHEX || Coinkite || PGP: A3A31BAD 5A2A5B10 [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 488 bytes --] ^ permalink raw reply [flat|nested] 7+ messages in thread

It's the best. UR is more than just a QR, it is URL conformant text that is optimized for compression in QRs. In particular, take a look at the explanation of the UR format at the 20m0s mark in this video: https://youtu.be/RYgOFSdUqWY The rest of the video explains why we made the choices we did. We wanted to leverage existing standards, but there were too many compromises expecially give QR requirements. See the section on “Why Another Standard” in our overview at https://github.com/BlockchainCommons/crypto-commons/blob/master/Docs/ur-1-overview.md#why-another-standard Note that the UR specification just is not just being adopted by wallet vendors, but also a number of online services / transaction coordinators that only have access watch-only keys. These services can then do a crypto-request for the airgapped wallet to sign the PSBT. — Christopher Allen > [-- Attachment #2: Type: text/html, Size: 2754 bytes --] ^ permalink raw reply [flat|nested] 7+ messages in thread

Gray 1 sibling, 1 reply; 7+ messages in thread From: Andrew Chow @ 2021-08-31 19:46 UTC (permalink / raw) To: Peter Gray, Bitcoin Protocol Discussion Hi Peter, It would be nice to have mime types registered for Bitcoin things, but I'm not sure that it will be possible, at least not in the way that we would like. I tried doing this with "application/bitcoin-psbt" back in 2019 but it was not accepted. From that attempt, here is what I have learned: There are only a few accepted top level types, so we would not be able to use "bitcoin" as the top level (unless you want to submit an RFC to add a "bitcoin" top level). Of the available top level types, "application" is the most appropriate for Bitcoin. Next is the tree that the mime type should be in. The best would be the Standards tree, but it has some requirements that Bitcoin doesn't really meet. In order to be in the standards tree, the registration must be either associated with an IETF specification (so a RFC) or registered by a recognized standards related organization. Unfortunately the closest thing to a standards organization that Bitcoin has is the BIPs process, and that is not a really a standards organization nor is it recognized by IANA. So in order to register the mimetypes as Standards tree types, we would need to write an RFC, but this could be an independent submission (https://www.rfc-editor.org/about/independent/) rather than IETF-stream submission. I did not continue to pursue this because I didn't have the time. Another alternative would be to use the Vendor tree, but that would prefix the mimetype with "vnd." so it would end up being something like "application/vnd.bitcoin.psbt". I did not think this was an reasonable so I did not continue to pursue this avenue. Andrew Chow On 8/31/21 2:27 PM, Peter D.

Based on your experience, we should probably ignore the IANA then, and just declare a few useful "mime types" (note the quotes) in a new BIP. We can then agree inside the Bitcoin community on their usage and meaning. Anyone want to write that BIP and shepherd it? I can support you but I'd rather write code. --- @DocHEX || Coinkite || PGP: A3A31BAD 5A2A5B10 On Tue, Aug 31, 2021 at 07:46:55PM +0000, Andrew Chow wrote: > Hi Peter, > > It would be nice to have mime types registered for Bitcoin things, but > I'm not sure that it will be possible, at least not in the way that we > would like.
