Adam Back&#39;s extension blocks proposal would, in fact,&#xA;&gt; allow for a soft forking change that creates more subsidy than is valid (or&#xA;&gt; does anything else) by hiding one block inside another.&#xA;&gt;&#xA;&#xA;Maybe I&#39;m missing something, but wouldn&#39;t this turn into a hard fork the&#xA;moment you try to spend an output created in one of these extension blocks?&#xA;So sure, the block that contains the extension would be considered valid,&#xA;but unupgraded validators will not update the UTXO set accordingly, meaning&#xA;that those new TXOs can&#39;t be spent because, according to their rules, they&#xA;don&#39;t exist.&#xA;&#xA;&gt;&#xA;&gt;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20151007/a86d8d32/attachment-0001.html&gt;</html></oembed>
