The&#xA;only requirement coming from this would be to move your coins about once&#xA;every 10 years or so, which you should be able to do if you have your&#xA;private keys (you should!). You say it may be something to consider when&#xA;computer breakthroughs makes old outputs vulnerable, but I say it&#39;s not&#xA;&#34;if&#34; but &#34;when&#34; it happens, and by telling firsthand people that their&#xA;coins requires moving every once in a long while you ensure they won&#39;t&#xA;do stupid things or come back 50 years from now and complain their&#xA;addresses have been scavenged.&#xA;&#xA;--&#xA;Thomas&#xA;&#xA;On 22/08/17 10:29 AM, Erik Aronesty via bitcoin-dev wrote:&#xA;&gt; I agree, it is only a good idea in the event of a quantum computing&#xA;&gt; threat to the security of Bitcoin.  &#xA;&gt;&#xA;&gt; On Tue, Aug 22, 2017 at 9:45 AM, Chris Riley via bitcoin-dev&#xA;&gt; &lt;bitcoin-dev at lists.linuxfoundation.org&#xA;&gt; &lt;mailto:bitcoin-dev at lists.linuxfoundation.org&gt;&gt; wrote:&#xA;&gt;&#xA;&gt;     This seems to be drifting off into alt-coin discussion.  The idea&#xA;&gt;     that we can change the rules and steal coins at a later date&#xA;&gt;     because they are &#34;stale&#34; or someone is &#34;hoarding&#34; is antithetical&#xA;&gt;     to one of the points of bitcoin in that you can no longer control&#xA;&gt;     your own money (&#34;be your own bank&#34;) because someone can at a later&#xA;&gt;     date take your coins for some reason that is outside your control&#xA;&gt;     and solely based on some rationalization by a third party.  Once&#xA;&gt;     the rule is established that there are valid reasons why someone&#xA;&gt;     should not have control of their own bitcoins, what other reasons&#xA;&gt;     will then be determined to be valid?&#xA;&gt;&#xA;&gt;     I can imagine Hal Finney being revived (he was cryo-preserved at&#xA;&gt;     Alcor if you aren&#39;t aware) after 100 or 200 years expecting his&#xA;&gt;     coins to be there only to find out that his coins were deemed&#xA;&gt;     &#34;stale&#34; so were &#34;reclaimed&#34; (in the current doublespeak - e.g.&#xA;&gt;     stolen or confiscated).  Or perhaps he locked some for his&#xA;&gt;     children and they are found to be &#34;stale&#34; before they are&#xA;&gt;     available.  He said in March 2013, &#34;I think they&#39;re safe enough&#34;&#xA;&gt;     stored in a paper wallet.  Perhaps any remaining coins are no&#xA;&gt;     longer &#34;safe enough.&#34;&#xA;&gt;&#xA;&gt;     Again, this seems (a) more about an alt-coin/bitcoin fork or (b)&#xA;&gt;     better in bitcoin-discuss at best vs bitcoin-dev. I&#39;ve seen it&#xA;&gt;     discussed many times since 2010 and still do not agree with the&#xA;&gt;     rational that embracing allowing someone to steal someone else&#39;s&#xA;&gt;     coins for any reason is a useful change to bitcoin.&#xA;&gt;&#xA;&gt;&#xA;&gt;&#xA;&gt;&#xA;&gt;     On Tue, Aug 22, 2017 at 4:19 AM, Matthew Beton via bitcoin-dev&#xA;&gt;     &lt;bitcoin-dev at lists.linuxfoundation.org&#xA;&gt;     &lt;mailto:bitcoin-dev at lists.linuxfoundation.org&gt;&gt; wrote:&#xA;&gt;&#xA;&gt;         Okay so I quite like this idea. If we start removing at height&#xA;&gt;         630000 or 840000 (gives us 4-8 years to develop this&#xA;&gt;         solution), it stays nice and neat with the halving interval.&#xA;&gt;         We can look at this like so:&#xA;&gt;&#xA;&gt;         B - the current block number&#xA;&gt;         P - how many blocks behind current the coin burning block is.&#xA;&gt;         (630000, 840000, or otherwise.)&#xA;&gt;&#xA;&gt;         Every time we mine a new block, we go to block (B-P), and&#xA;&gt;         check for stale coins. These coins get burnt up and pooled&#xA;&gt;         into block B&#39;s miner fees. This keeps the mining rewards up in&#xA;&gt;         the long term, people are less likely to stop mining due to&#xA;&gt;         too low fees. It also encourages people to keep moving their&#xA;&gt;         money around the enconomy instead of just hording and leaving it.&#xA;&gt;&#xA;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20170822/bc4992c0/attachment.html&gt;</html></oembed>
