I fully agree with sipa and his reasoning that this proposal is not solving any particular problem, but making it actually a bit worse. Also, do you know what I hate more than copy&pasting bitcoin addresses? Copy pasting zillion random fields for SEPA/wire transfers. And I believe that a single co

Hi ZmnSCPxj, Thank you for your helpful response. We're on the same page concerning privacy so I'll focus on that. I understand from your mail that privacy would be reduced by this proposal because: * It requires the introduction of a new type of transaction that is different from a "standard" tr

[bitcoin-dev] Proposal for a few IANA mime-types related to Bitcoin

2021-08-31 Thread Peter D. Gray via bitcoin-dev
Hi list! I am proposing to register the following MIME (RFC 2046) media types with the IANA: bitcoin/psbt - aka. a BIP-174 file, in binary - does not make any claims about signed/unsigned status; lets leave that to the file bitcoin/txn - aka. wire-ready fully-signed transaction

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 learne

Note that a number of wallet companies are now supporting the UR encoded version of PSBTs, allowing for better QR & Airgap solutions, and also leverage CBOR which is an IETF standard. We have a community of Airgap wallet developers at https://github.com/BlockchainCommons/Airgapped-Wallet-Community

QR Codes do not use IANA mime-types. If anyone wanted to use UR encoding for PSBT data in a web context (http), NFC, or email, it would probably be best to discourage them. While I can understand the need for UR encoding in animated QR codes, I don't think any other use-case could justify introdu
