To ensure forward compatibility with optional fields, we need to define how a client handles fields that it doesn't know about. When should it display an error message, and when should it silently accept and ignore the extraneous fields? (For example, if something that restricts the validity, suc

I think that the "send to private address" field will require more effort to implement than the simpler "expires" and "message" fields and should be deferred to a later BIP. There is a pressing need for expires and the only point of contention I see is the inclusion of a dual representation (block

I also wonder whether the "send to private address" should be part of this BIP, or a future one. IMO (but your mileage may vary) this BIP should only define the bare-bones URL scheme, AND provide room for future extensions such as send-to-private-address, send-multiple-signers, and so on. These sh

Generally I prefer BIP 21 over BIP 20. I'm neutral on the 'send' parameter - present in both BIPs - which I don't understand. I think a practical usecase should be given in the BIP. Also, the 'version' parameter is unclear. What does it mean? Is an oder defined on versions (1.0b > 1.0)? Why is it

Having closely read the BIP20 proposal, I can see your point. As I see it, BIP 20 vs BIP 21 is about standardising on a representation of the "amount" field. BIP 20 proposes that "amount" can contain alternative representations, clearly defined, whereas BIP 21 requires the use of a single represent

Hi all, Speaking on behalf of the MultiBit team (Jim's currently on holiday), we will not be supporting Tonal Bitcoins anytime soon. Therefore we back the BIP 21 proposal. At present MultiBit does not support the "message" or "send" fields but we would be happy to add this functionality as requir

I too support BIP21 over BIP20. However, I do not understand the "Sending money via private key" feature; in which situation would such a URI be useful? Also, I posted a proposal in the forum, to extend the URI syntax with signatures. The goal would be to provide a proof of identity of the recip
