But at the\n\u003e same time I want to be able to support BIP70. And also I want to avoid\n\u003e using external servers, the concept of my POS is that everything is\n\u003e happening between just payer's phone and payee's POS device. This means\n\u003e that BIP72 HTTP(S) link inside Bitcoin URI is not suitable for me.\n\u003e\n\u003e You're also offering an option to include Base43 encoded PR body right\n\u003e inside the Bitcoin URI, but in a way that is not backwards compatible with\n\u003e BIP21.\n\u003e\n\u003e In the end this all means that there is no way for me to at the same time\n\u003e keep backwards compatibility with all wallets not supporting NFC and BIP70\n\u003e (all other wallets right now), and keep things inside POS without need for\n\u003e external servers.\n\u003e\n\u003e I understand your intention behind base43 encoding and noncompatible URI -\n\u003e you want to make most possible use of QR codes. But I wonder - did you\n\u003e compare this base43 to base64 encoded request in a binary QR code format?\n\u003e How much do we actually win in total bytes capacity at a price of\n\u003e noncompatibility and increased complexity?\n\u003e\n\u003e And also maybe we can extend BIP72 to include encoded payment request in\n\u003e the URL directly in a backwards compatible way?\n\u003e\n\u003e\n\u003e Best regards,\n\u003e Alex Kotenko\n\u003e\n\u003e\n\u003e 2014-03-02 11:50 GMT+00:00 Mike Hearn \u003cmike at plan99.net\u003e:\n\u003e\n\u003e\u003e  Thanks Andreas.\n\u003e\u003e\n\u003e\u003e For BIP standardisation, I think the VIEW intent seems like an obvious\n\u003e\u003e one. Bluetooth support probably should come later if/when we put\n\u003e\u003e encryption/auth on the RFCOMM link (probably SSL).\n\u003e\u003e\n\u003e\u003e\n\u003e\u003e ------------------------------------------------------------------------------\n\u003e\u003e Flow-based real-time traffic analytics software.
