Also, consider using SI prefixes. They are standard throughout the world (except America). Genjix 08:04, 10 January 2011 (GMT)

  • SI/decimal is the inferior competition/enemy of the superior Tonal system. That is, to be avoided. (Chinese is a standard language throughout most of the world too! And whatever the currency of China is-- should we not use bitcoins??) Luke-jr 15:05, 10 January 2011 (GMT)

Can someone fix the name of the page? It's "Scheme", not "Schema". Luke-jr 15:35, 10 January 2011 (GMT)

maybe even "URI scheme" to be more precise? since there can be many differenct schemes about stuff. :) --Nanotube 05:48, 12 January 2011 (GMT)
Numerical Syntax
  • Wouldn't it be better if we used the more standard "e" to represent the exponent? e.g. 5e8 = 500,000,000. - Weavejester 11:18 PM, 18 April 2011 (GMT)
    • Ah, I see exponents are also allowed for hexadecimals, which would preclude the use of "e". What's the reason for allowing both decimal and hexadecimal value strings? Are there particular use-cases where hex is useful? - Weavejester 12:25 AM, 19 April 2011 (GMT)
Fallback URI

On Android an app can register to open with a normal web URI. This has the advantage of acting as a fallback URI in case there is no app that supports bitcoin:. For example we could propose https://en.bitcoin.it/wiki/Send/<address>[?][amount=<size>][&][label=<label>][&][message=<message>]. If the user had a mobile app that supported bitcoin it would have registered https://en.bitcoin.it/wiki/Send/ and be launched. If the user did not have such an app their browser would launch and be directed to https://en.bitcoin.it/wiki/Send/. This page could then inform the user about various apps that support bitcoin transfers and possibly have a link to MyBitcoin as well. Maybe https://bitcoin.org/Send/ would be more appropriate, though that one might not be updated often enough.

  • iPhone support

There is even a way to have this work on iOS devices. Have the web page redirect to the standard bitcoin: scheme. If an app is present to support this the app will launch, if not the browser the will stay open at the explanation page.

  • Upshot

This fallback proposal will make bitcoin QR codes meaningful regardless of if the user has a bitcoin app installed.--BitMark 16:05, 2 April 2011 (GMT)

Use-cases - buy this link

On the buy-this link, perhaps we should also incorporate an optional transaction id or something which would be passed along to the bitcoin client. Not really transaction but some sort of arbitrary data, only meaningful to the merchant. Something an online merchant can use to verify which transaction it has received is relevant to a purchase.
