I can sincerely intend to do a lot of things, but this doesn&#39;t mean I&#39;ll ever actually do them.&#xA;&#xA;I am in favor of more zero-confirmation transactions being reversed / double-spent. Bitcoin users largely still believe that accepting zero-conf transactions is safe, and evidently it&#39;s going to take some harsh lessons in reality to correct this belief.&#xA;&#xA;&#xA;On Friday, 19 June 2015, at 9:42 am, Eric Lombrozo wrote:&#xA;&gt; If we want a non-repudiation mechanism in the protocol, we should explicitly define one rather than relying on “prima facie” assumptions. Otherwise, I would recommend not relying on the existence of a signed transaction as proof of intent to pay…&#xA;&gt; &#xA;&gt; &#xA;&gt; &gt; On Jun 19, 2015, at 9:36 AM, Matt Whitlock &lt;bip at mattwhitlock.name&gt; wrote:&#xA;&gt; &gt; &#xA;&gt; &gt; On Friday, 19 June 2015, at 3:53 pm, justusranvier at riseup.net wrote:&#xA;&gt; &gt;&gt; I&#39;d also like to note that &#34;prima facie&#34; doesn&#39;t mean &#34;always&#34;, it means&#xA;&gt; &gt;&gt; that &#34;the default assumption, unless proven otherwise.&#34;&#xA;&gt; &gt; &#xA;&gt; &gt; Why would you automatically assume fraud by default? Shouldn&#39;t the null hypothesis be the default? Without any information one way or another, you ought to make *no assumption* about the fraudulence or non-fraudulence of any given double-spend.&#xA;&gt;</html></oembed>
