The recent evens (see the thread titled&#xA;&gt; &#34;OpenSSL 1.0.0p / 1.0.1k incompatible, causes blockchain rejection.&#34;&#xA;&gt; on this mailing list) have made it clear that the problem is very&#xA;&gt; real, however, and I would prefer to have a fundamental solution for&#xA;&gt; it sooner rather than later.&#xA;&gt; &#xA;&gt; I therefore propose a softfork to make non-DER signatures illegal&#xA;&gt; (they&#39;ve been non-standard since v0.8.0). A draft BIP text can be&#xA;&gt; found on:&#xA;&gt; &#xA;&gt;     https://gist.github.com/sipa/5d12c343746dad376c80&#xA;&gt; &#xA;&gt; The document includes motivation and specification. In addition, an&#xA;&gt; implementation (including unit tests derived from the BIP text) can be&#xA;&gt; found on:&#xA;&gt; &#xA;&gt;     https://github.com/sipa/bitcoin/commit/bipstrictder&#xA;&gt; &#xA;&gt; Comments/criticisms are very welcome, but I&#39;d prefer keeping the&#xA;&gt; discussion here on the mailinglist (which is more accessible than on&#xA;&gt; the gist).&#xA;&#xA;-- &#xA;&#39;peter&#39;[:-1]@petertodd.org&#xA;00000000000000001a5e1dc75b28e8445c6e8a5c35c76637e33a3e96d487b74c&#xA;-------------- next part --------------&#xA;A non-text attachment was scrubbed...&#xA;Name: signature.asc&#xA;Type: application/pgp-signature&#xA;Size: 650 bytes&#xA;Desc: Digital signature&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150121/39547316/attachment.sig&gt;</html></oembed>
