Now even if all of them are using Taproot outputs&#xA;you&#39;re still leaking what protocol/tooling you&#39;re using to an external&#xA;observer&#xA;due to discrepancies in transaction fields. So we should obfuscate or using&#xA;standard values as much as protocol semantics let us doing it to break chain&#xA;analysis heuristics.&#xA;&#xA;Le mer. 29 janv. 2020 à 21:00, lisa neigut &lt;niftynei at gmail.com&gt; a écrit :&#xA;&#xA;&gt; hi max — great question. PSBT is a great protocol for wallet interop but a&#xA;&gt; bit overweight for tx collaboration between two peers&#xA;&gt;&#xA;&gt; On Wed, Jan 29, 2020 at 17:29 Max Dignan &lt;maxdignan at gmail.com&gt; wrote:&#xA;&gt;&#xA;&gt;&gt; Hey Antoine,&#xA;&gt;&gt;&#xA;&gt;&gt; Would PSBT (BIP 174 -&#xA;&gt;&gt; https://github.com/bitcoin/bips/blob/master/bip-0174.mediawiki) be a&#xA;&gt;&gt; good solution to this?&#xA;&gt;&gt;&#xA;&gt;&gt; -Max&#xA;&gt;&gt; _______________________________________________&#xA;&gt;&gt; Lightning-dev mailing list&#xA;&gt;&gt; Lightning-dev at lists.linuxfoundation.org&#xA;&gt;&gt; https://lists.linuxfoundation.org/mailman/listinfo/lightning-dev&#xA;&gt;&gt;&#xA;&gt;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/lightning-dev/attachments/20200129/9921c64a/attachment.html&gt;</html></oembed>
