We&#39;re talking&#xA;about an increase now that scales into the future at a rate that is&#xA;consistent with technological progress.&#xA;&#xA;Peter himself said &#34;So, I think the block size should follow technological&#xA;evolution...&#34;.&#xA;&#xA;The blocksize increase proposals have been modeled around this very thing.&#xA;It&#39;s reasonable to increase the blocksize to a point that a reasonable&#xA;person, with reasonable equipment and internet access can run a node or&#xA;even a miner with acceptable orphan rates.  Most miners are spv mining&#xA;anyways.  The 8 or even 20 MB limits are within those parameters.&#xA;&#xA;These are not mutually exclusive.  We can design an increase to blocksize&#xA;that addresses both demand exceeding the available space AND follow&#xA;technological evolution.  Peter&#39;s latest proposal is way too conservative&#xA;on that front.&#xA;On Aug 7, 2015 1:25 PM, &#34;Mark Friedenbach&#34; &lt;mark at friedenbach.org&gt; wrote:&#xA;&#xA;&gt; Please don&#39;t put words into Pieter&#39;s mouth. I guarantee you everyone&#xA;&gt; working on Bitcoin in their heart of hearts would prefer everyone in the&#xA;&gt; world being able to use the Bitcoin ledger for whatever purpose, if there&#xA;&gt; were no cost.&#xA;&gt;&#xA;&gt; But like any real world engineering issue, this is a matter of tradeoffs.&#xA;&gt; At the extreme it is simply impossible to scale Bitcoin to the terrabyte&#xA;&gt; sized blocks that would be necessary to service the entire world&#39;s&#xA;&gt; financial transactions. Not without sacrificing entirely the protection of&#xA;&gt; policy neutrality achieved through decentralization. And as that is&#xA;&gt; Bitcoin&#39;s only advantage over traditional consensus systems, you would have&#xA;&gt; to wonder what the point of such an endeavor would be.&#xA;&gt;&#xA;&gt; So *somewhere* you have to draw the line, and transactions below that&#xA;&gt; level are simply pushed into higher level or off-chain protocols.&#xA;&gt;&#xA;&gt; The issue, as Pieter and Jorge have been pointing out, is that technical&#xA;&gt; discussion over where that line should be has been missing from this debate.&#xA;&gt;&#xA;&gt; On Fri, Aug 7, 2015 at 10:47 AM, Ryan Butler via bitcoin-dev &lt;&#xA;&gt; bitcoin-dev at lists.linuxfoundation.org&gt; wrote:&#xA;&gt;&#xA;&gt;&gt; Interesting position there Peter...you fear more people actually using&#xA;&gt;&gt; bitcoin.  The less on chain transactions the lower the velocity and the&#xA;&gt;&gt; lower the value of the network.  I would be careful what you ask for&#xA;&gt;&gt; because you end up having nothing left to even root the security of these&#xA;&gt;&gt; off chain transactions with and then neither will exist.&#xA;&gt;&gt;&#xA;&gt;&gt; Nobody ever said you wouldn&#39;t run out of capacity at any size.  It&#39;s&#xA;&gt;&gt; quite the fallacy to draw the conclusion from that statement that block&#xA;&gt;&gt; size should remain far below a capacity it can easily maintain which would&#xA;&gt;&gt; bring more users/velocity/value to the system.  The outcomes of both of&#xA;&gt;&gt; those scenarios are asymmetric.  A higher block size can support more users&#xA;&gt;&gt; and volume.&#xA;&gt;&gt;&#xA;&gt;&gt; Raising the blocksize isn&#39;t out of fear.  It&#39;s the realization that we&#xA;&gt;&gt; are at a point where we can raise it and support more users and&#xA;&gt;&gt; transactions while keeping the downsides to a minimum (centralization etc).&#xA;&gt;&gt; On Aug 7, 2015 11:28 AM, &#34;Pieter Wuille via bitcoin-dev&#34; &lt;&#xA;&gt;&gt; bitcoin-dev at lists.linuxfoundation.org&gt; wrote:&#xA;&gt;&gt;&#xA;&gt;&gt;&gt; On Fri, Aug 7, 2015 at 5:55 PM, Gavin Andresen &lt;gavinandresen at gmail.com&gt;&#xA;&gt;&gt;&gt; wrote:&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt; On Fri, Aug 7, 2015 at 11:16 AM, Pieter Wuille &lt;pieter.wuille at gmail.com&#xA;&gt;&gt;&gt;&gt; &gt; wrote:&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt;&gt; I guess my question (and perhaps that&#39;s what Jorge is after): do you&#xA;&gt;&gt;&gt;&gt;&gt; feel that blocks should be increased in response to (or for fear of) such a&#xA;&gt;&gt;&gt;&gt;&gt; scenario.&#xA;&gt;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt; I think there are multiple reasons to raise the maximum block size, and&#xA;&gt;&gt;&gt;&gt; yes, fear of Bad Things Happening as we run up against the 1MB limit is one&#xA;&gt;&gt;&gt;&gt; of the reasons.&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt; I take the opinion of smart engineers who actually do resource planning&#xA;&gt;&gt;&gt;&gt; and have seen what happens when networks run out of capacity very seriously.&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt; This is a fundamental disagreement then. I believe that the demand is&#xA;&gt;&gt;&gt; infinite if you don&#39;t set a fee minimum (and I don&#39;t think we should), and&#xA;&gt;&gt;&gt; it just takes time for the market to find a way to fill whatever is&#xA;&gt;&gt;&gt; available - the rest goes into off-chain systems anyway. You will run out&#xA;&gt;&gt;&gt; of capacity at any size, and acting out of fear of that reality does not&#xA;&gt;&gt;&gt; improve the system. Whatever size blocks are actually produced, I believe&#xA;&gt;&gt;&gt; the result will either be something people consider too small to be&#xA;&gt;&gt;&gt; competitive (&#34;you mean Bitcoin can only do 24 transactions per second?&#34;&#xA;&gt;&gt;&gt; sounds almost the same as &#34;you mean Bitcoin can only do 3 transactions per&#xA;&gt;&gt;&gt; second?&#34;), or something that is very centralized in practice, and likely&#xA;&gt;&gt;&gt; both.&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt; And if so, if that is a reason for increase now, won&#39;t it be a reason&#xA;&gt;&gt;&gt;&gt;&gt; for an increase later as well? It is my impression that your answer is yes,&#xA;&gt;&gt;&gt;&gt;&gt; that this is why you want to increase the block size quickly and&#xA;&gt;&gt;&gt;&gt;&gt; significantly, but correct me if I&#39;m wrong.&#xA;&gt;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt; Sure, it might be a reason for an increase later. Here&#39;s my message to&#xA;&gt;&gt;&gt;&gt; in-the-future Bitcoin engineers:  you should consider raising the maximum&#xA;&gt;&gt;&gt;&gt; block size if needed and you think the benefits of doing so (like increased&#xA;&gt;&gt;&gt;&gt; adoption or lower transaction fees or increased reliability) outweigh the&#xA;&gt;&gt;&gt;&gt; costs (like higher operating costs for full-nodes or the disruption caused&#xA;&gt;&gt;&gt;&gt; by ANY consensus rule change).&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt; In general that sounds reasonable, but it&#39;s a dangerous precedent to&#xA;&gt;&gt;&gt; make technical decisions based on a fear of change of economics...&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt; --&#xA;&gt;&gt;&gt; Pieter&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt; _______________________________________________&#xA;&gt;&gt;&gt; bitcoin-dev mailing list&#xA;&gt;&gt;&gt; bitcoin-dev at lists.linuxfoundation.org&#xA;&gt;&gt;&gt; https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&#xA;&gt;&gt; _______________________________________________&#xA;&gt;&gt; bitcoin-dev mailing list&#xA;&gt;&gt; bitcoin-dev at lists.linuxfoundation.org&#xA;&gt;&gt; https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev&#xA;&gt;&gt;&#xA;&gt;&gt;&#xA;&gt;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150807/33b2af03/attachment-0001.html&gt;</html></oembed>
