That way the popup isn&#39;t only shown for&#xA;addresses that are reused after updating.&#xA;&#xA;&#xA;On 09/27/2017 12:35 PM, Chris Priest via bitcoin-dev wrote:&#xA;&gt; A better solution is to just have the sending wallet check to see if&#xA;&gt; the address you are about to send to has been used before. If it&#39;s a&#xA;&gt; fresh address, it sends it through without any popup alert. If the&#xA;&gt; address has history going back a certain amount of time, then a popup&#xA;&gt; comes up and notifies the sender that they are sending to a non-fresh&#xA;&gt; address that may no longer be controlled by the receiver anymore.&#xA;&gt;&#xA;&gt; Also, an even better idea is to set up an &#34;address expiration&#xA;&gt; service&#34;. When you delete a wallet, you first send off an &#34;expiration&#xA;&gt; notice&#34; which is just a message (signed with the private key) saying&#xA;&gt; &#34;I am about to delete this address, here is my new address&#34;. When&#xA;&gt; someone tries to send to that address, they first consult the address&#xA;&gt; expiration service, and the service will either tell them &#34;this&#xA;&gt; address is not expired, proceed&#34;, or &#34;this address has been expired,&#xA;&gt; please send to this other address instead...&#34;. Basically like a 301&#xA;&gt; redirect, but for addresses. I don&#39;t think address expiration should&#xA;&gt; be part of the protocol.&#xA;&gt;&#xA;...&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20170927/305de41f/attachment-0001.html&gt;</html></oembed>
