Recently a large merchant payment processor has decided to drop
support for BIP21 payment URI's in favor of accepting exclusively
BIP70 payments which has brought to light a number of problems with
BIP70:
1. Many wallets do not support BIP70 and have no near term intention
of doing so.
2. BIP70
Happy New Year all.
This proposal has been further amended with several minor changes and a
few additions.
I believe that all known issues raised so far have been sufficiently
addressed. Either that or, I still have more work to do.
## BIP Proposal: Revised: UTPFOTIB - Use Transaction Priority
