OP_CAT is defined as OP_SUCCESS, it can be&#xA;&gt; re-enabled in a soft-fork way. For now, OP_CAT in TapScript simply means&#xA;&gt; &#34;anyone can move those coins&#34;, so adding some restrictions is all we need&#xA;&gt; to re-enable this opcode. Introducing OP_CAT2 is not needed at all, unless&#xA;&gt; it will be totally different, but then it should not be named as OP_CAT2,&#xA;&gt; but rather as OP_SOMETHING_ELSE, it depends how different it will be from&#xA;&gt; OP_CAT.&#xA;&gt;&#xA;&#xA;Oh, well, I didn&#39;t know any of that. I guess it could be a modification of&#xA;OP_SUCCESS if it makes sense instead of a new opcode.&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20220507/6b3c1b24/attachment.html&gt;</html></oembed>
