🗒️ Summary of this message: Proposal for a way for merchants to translate a human-readable address into a bitcoin address, using HTTP(S) requests to a merchant-specified URL. Allows for per-transaction or fixed addresses.
📝 Original message:I think the scope of this BIP is not so well defined right now. We need a
way for merchants to translate a human readable, and more importantly
human-writeable, address into a bitcoin address. I agree with Mike that a
fixed address is not the way to go, because addresses should be used once
for a single transaction to be able to track payments.
While firstbits sounds attractive at first, I think we can all agree that
it just isn't feasible and would not allow per-transaction addresses. DNS
sounds interesting for fixed addresses, but caching and propagation make it
difficult to use for per-transaction addresses that are to be generated
ad-hoc.
HTTP(S) is the best option I think, merchants are probably using HTTP
anyway for their shops. So something like
http://merchant.com/btc/transaction/1234 sounds reasonable. But I think it
should not be over-engineered, it should be a simple HTTP(S) request to a
merchant specified URL that returns an ASCII document containing either a
bitcoin: URI or simply the bitcoin address or even a 301 redirect. It's no
use to start defining URL schemes, it should be left to the merchants to
define how to structure them.
This would allow a merchant to decide if he prefers per-transaction
addresses, per-user transactions, fixed addresses or any combination.
