This can be solved by the market.&#xA;&#xA;What is needed is a simple method for each individual user to mark&#xA;certain merchant as trusted. For example, if your device gets an&#xA;untrusted payment request, it&#39;ll make a small sound, light up the screen&#xA;and ask the user to authorize the payment. The user then has the choice&#xA;of adding the merchant to trust list, authorizing just a single&#xA;transaction or not paying (and perhaps adding to the user&#39;s publicly&#xA;shared untrusted list?).&#xA;&#xA;This way, even lacking a trust architecture, only the first payment to a&#xA;merchant needs to take several seconds. If trust is granted, the next&#xA;payments will be swift.&#xA;&#xA;The lack of chargebacks presents a clear risk to the customer, though,&#xA;so a need for a third party that can keep the merchants honest exists.&#xA;This opens up markets for transaction insurance companies. Even though&#xA;bitcoin transactions are final, if a transaction insurance company&#xA;offers to cover your losses in the event of fraudulent charge, the risk&#xA;is practically eliminated.&#xA;&#xA;Such an insurance company would have a strong incentive to make sure the&#xA;merchants they insure for behave. Otherwise they&#39;ll suffer the losses. I&#xA;think this would result in an equally trustworthy but more decentralized&#xA;system than with credit cards.&#xA;&#xA;- Joel&#xA;&#xA;On 06.03.2014 16:20, Brooks Boyd wrote:&#xA;&gt;&#xA;&gt;&#xA;&gt; On Mar 6, 2014 3:47 AM, &#34;Mike Hearn&#34; &lt;mike at plan99.net&#xA;&gt; &lt;mailto:mike at plan99.net&gt;&gt; wrote:&#xA;&gt; &gt;&#xA;&gt; &gt; I just did my first contactless nfc payment with a MasterCard. It&#xA;&gt; worked very well and was quite delightful - definitely want to be&#xA;&gt; doing more of these in future. I think people will come to expect this&#xA;&gt; kind of no-friction payment experience and Bitcoin will need to match&#xA;&gt; it, so here are some notes on what&#39;s involved.&#xA;&gt; &gt;&#xA;&gt; &gt; 3) Have some kind of decentralised reputation network. I spent some&#xA;&gt; time thinking about this, but it rapidly became very complicated and&#xA;&gt; feels like an entirely separate project that should stand alone from&#xA;&gt; Bitcoin itself. Perhaps rather than try to make a global system,&#xA;&gt; social data could be exchanged (using some fancy privacy preserving&#xA;&gt; protocols?) so if your friends have decided to trust seller X, your&#xA;&gt; phone automatically trusts them too.&#xA;&gt;&#xA;&gt; A reputation network might be an interesting idea, or several&#xA;&gt; different networks with different curators (to prevent complete&#xA;&gt; centralization), like how the US credit score system has three main&#xA;&gt; companies who track your score. Something like a GPG ring of trust,&#xA;&gt; with addresses signing other addresses would work well, if some sort&#xA;&gt; of Stealth address or HD wallet root was the identity gaining the&#xA;&gt; reputation, then address re-use wouldn&#39;t have to be mandatory.&#xA;&gt;&#xA;&gt;&#xA;&gt;&#xA;&gt; ------------------------------------------------------------------------------&#xA;&gt; Subversion Kills Productivity.
