Hi,
[I sent this email 2 days ago prior my registration to the mailing list; please
forgive me if this is a duplicate]
I would like to propose an extension to the Payment Protocol (bip-0070) to
address the case of recurring payments in Bitcoin -- new bip or modification of
bip-0070.
There has been a lot of growth in the last few years in the 'subscription
economy' with many new companies embracing that model -- online video, gaming,
groceries, newspapers,... In parallel, Bitcoin is growing into a mainstream
currency (hence bip-0070), and so the next logical step would be to define a
protocol to address that need.
We have been working in the past few years on an open-source billing platform
(http://kill-bill.org/), and recently came with a prototype to do recurring
billing in Bitcoin (see
http://thekillbillstory.wordpress.com/2014/01/20/bitcoin-plugin/ and
http://thekillbillstory.wordpress.com/2014/01/11/coinbase-integration-experiment/).
The work flow would look similar to the one from bip-0070. There would need to
be some additions; the flow could be summarized as follow:
0. Click: 'Subscribe Now'
1. Wallet would get a RecurringPaymentRequestAuth which describes the nature
of the future recurring payments
2. The Customer would get prompted from the wallet to authorize it.
3. The wallet would then poll the Merchant server (startup time, and/or well
defined frequency) and potentially merchant would start issuing a
PaymentRequest); the role of the wallet is to ensure that PaymentRequest is
within the bounds of what was accepted by the customer-- amount, frequency,..
If it is, then it would make the Payment the same way it works for bip-0070
Is that something that the community would be interested in? We could provide
more details about the protocol we have in mind (messages and flow), and also
provide an implementation with bitcoinj as a wallet and Kill Bill as a merchant
server.
Le me know what you think.
