The recipient needs to understand that what&#xA;he received is nothing more than an IOU that can be revoked at any time. If&#xA;the UI makes it clear and the user trusts the sender, no problem. BIP70&#xA;would work as before.&#xA;&#xA;&#xA;On Sat, Mar 22, 2014 at 6:24 PM, Jeff Garzik &lt;jgarzik at bitpay.com&gt; wrote:&#xA;&#xA;&gt; One participant, yes.  Two participants lacking net would require a&#xA;&gt; serious revisit of BIP 70&#39;s security assumptions and some design, at a&#xA;&gt; minimum.&#xA;&gt;&#xA;&gt; On Sat, Mar 22, 2014 at 12:55 PM, Mark Friedenbach &lt;mark at monetize.io&gt;&#xA;&gt; wrote:&#xA;&gt; &gt; Jeff, there are *plenty* of places that lack local Internet access for&#xA;&gt; &gt; one or both participants.&#xA;&gt; &gt;&#xA;&gt; &gt; Obviously making the case where both participants lack access to the&#xA;&gt; &gt; bitcoin network is difficult to secure, but not impossible (e.g. use a&#xA;&gt; &gt; telephany-based system to connect to a centralized double-spend&#xA;&gt; &gt; database, as VISA does).&#xA;&gt; &gt;&#xA;&gt; &gt; I expect the case where one participant has Internet access (the&#xA;&gt; &gt; merchant) and the other does not to be very, very common. The majority&#xA;&gt; &gt; of transactions I do on a daily basis are like this, and I live in&#xA;&gt; &gt; Silicon Valley!&#xA;&gt; &gt;&#xA;&gt; &gt; On 03/22/2014 09:35 AM, Jeff Garzik wrote:&#xA;&gt; &gt;&gt; Let&#39;s not pull out silly examples.
