Of course, it only works when&#xA;transactions are actually in a block.&#xA;&#xA;This issue is about double-spending preventing before they&#39;re&#xA;confirmed. This is (and has always been) just a best-effort mechanism&#xA;in the network.&#xA;&#xA;&gt; 2.  Is it possible to &#34;scan&#34; for double-spending and correct it?&#xA;&#xA;That is what is being proposed here, by introducing a mechanism where&#xA;miners can vote to penalize other miners if they seem to allow (too&#xA;many?) double spends.&#xA;&#xA;&gt; 3.  Is the network at large not secure enough?&#xA;&#xA;Not very relevant.&#xA;&#xA;-- &#xA;Pieter</html></oembed>
