Draft BIP: Well-Known Bitcoin Identity Endpoint

Hi all,
I'd like to propose a new BIP titled "Well-Known Bitcoin Identity Endpoint." The goal is to improve the user experience for sending on-chain Bitcoin payments by allowing wallets to resolve a Lightning Address into associated on-chain addresses and additional metadata.
The idea is to define a simple, HTTPS-based standard for retrieving payment and contact information via a .well-known endpoint, generalizing the approach used by Lightning Address to support more payment types and identity metadata.
You can find the draft BIP here: https://github.com/aviv57/paysats/blob/main/bip/BIPXXX.MD
I’d appreciate any feedback or suggestions.
Thanks, AvivB
Hi AvivB,
Something similar has been discussed here in BIP 353: https://github.com/bitcoin/bips/blob/master/bip-0353.mediawiki#dns-rather-than-http-based-solutions
Cheers, Hodlinator

(Reading further down in your proposal I see you do acknowledge BIP 353 and the arguments laid out there, sorry for the noise).

Hi Aviv,
Thanks for posting about your BIP idea. I must admit that I have lost track of the finer details of Lightning Addresses, LNURL, and other similar schemes, so I’m not in a position to comment on a comparison of your idea to those. One of the criticisms that I remember from when Lightning Address was first introduced was that it would have been better to avoid the email format. After glancing at your draft, I would like to suggest that you clarify how you propose that the paysats would be communicated. I would suggest staying clear of the email format, not only, because senders sometimes mistake it for an email address, but also because there are now other similar schemes that use email formatting already and it would not be clear which resolution to use when encountering it. Otherwise, this seems like a decent start of a BIP, although it would help if you lay out more clearly how your idea compares with similar schemes in the Rationale, in addition to what you already wrote about BIP 353.
Cheers,
Murch
