For me such total interoperability wasn't necessary, but after reading your post it makes sense. The success of any of the cryptocurrencies is good for all cryptocurrency, and making the transition from bitcoin to Litecoin should be easy to do from a users point of view. It's a good idea the interoperability.
Any takers so far?
Look, why are we wanting to have a QR Code payment processor?
To promote Litecoin as a payment solution, and not only as a store of value / exotic alt currency.
So if we are going to develop an app that allows to read and generate LTC QR codes, let's arrange to have it as widely adopted as possible.
If it reads only Litecoin QR codes, it will cater almost exclusively to existing Litecoin users.
Now if it reads both Litecoin and Bitcoin QR codes, it will show in the search results when people search for a Bitcoin QR code processor, and will be used both by Litecoin and Bitcoin users.
In the first case, promotional effect nil.
In the second case, many bitcoin consummers will have a little Litecoin logo on their QR code reader app, and become progressively aware of the existence of Litecoin as a payment solution.
And many bitcoin merchants will have this little Litecoin logo on their QR code generator app, and become progressively aware of the existance of Litecoin bearing potential customers.
Which do you prefer?
That being said, I'd like to precise the requirement for the 1500 BTC bounty as follow :
- The application should be able to both read and generate Bitcoin, Litecoin and Bitcoin+Litecoin QR codes.
- Bitcoin QR codes generated by the application should be readable by existing Bitcoin QR code readers (so exactly same format).
- Bitcoin QR codes generated by other generators should be readable by the application.
- The application should display both a Litecoin and Bitcoin logo in a neutral fashion.
- The application should be able to run on at least one major breed of smartphones (IPhones or Android phones).
crazy_rabbit : can you please update my requirements in post #1?
