Though some general things were thrown out, they were not&#xA;&gt; extensively discussed nor agreed to. I personally think 2-4 is &#34;in&#xA;&gt; range&#34;, though 8 maybe not so much. Of course it depends on exactly how&#xA;&gt; the non-blocksize limit accounting/adjusting is done.&#xA;&gt;&#xA;&gt; Still, the &#34;greatest common denominator&#34; agreement did not seem to be&#xA;&gt; agreeing to an increase which continues over time, but which instead&#xA;&gt; limits itself to a set, smooth increase for X time and then requires a&#xA;&gt; second hardfork if there is agreement on a need for more blocksize at&#xA;&gt; that point.&#xA;&gt;&#xA;&#xA;Perhaps it is accurate to say that there wasn&#39;t consensus at all except&#xA;that (1) we think we can work together on resolving this impasse (yay!),&#xA;and (2) it is conceivable that changing from block size to some other&#xA;metric might provide the basis for a compromise on near-term numbers.&#xA;&#xA;As an example, I do not think the net-UTXO metric provides any benefit with&#xA;respect to scalability, and in some ways makes the situation worse (even&#xA;though it helpfully solves an unrelated problem of spammy dust outputs).&#xA;But there are other possible metrics and I maintain hope that data will&#xA;show the benefit of another metric or other metrics combined with net-UTXO&#xA;in a way that will allow us to reach consensus.&#xA;&#xA;As a further example, I also am quite concerned about 2-4-8MB with either&#xA;block size or net-UTXO as the base metric. As you say, it depends on how&#xA;the non-blocksize limit accounting/adjusting is done... But if a metric&#xA;were chosen that addressed my concerns (worst case propagation and&#xA;validation time), then I could be in favor of an initial bump that allowed&#xA;a larger number of typical transactions in a block.&#xA;&#xA;But where I really need to disagree is on the requirement for a 2nd hard&#xA;fork. I will go on record as being definitively against this. While being&#xA;conservative with respect to exponentials, I would very much like to make&#xA;sure that there is a long-term growth curve as part of any proposal. I am&#xA;willing to accept a hard-fork if the adopted plan is too conservative, but&#xA;I do not want to be kicking the can down the road to a scheduled 2nd hard&#xA;fork that absolutely must occur. That, I feel, could be a more dangerous&#xA;outcome than an exponential that outlasts conservative historical trends.&#xA;&#xA;I commend Jeff for writing a Chatham-rules summary of the outcome of some&#xA;hallway conversations that occurred. On the whole I think his summary does&#xA;represent the majority view of the opinions expressed by core developers at&#xA;the workshop. I will caution though that on nearly every issue there were&#xA;those expressed disagreement but did not fight the issue, and those who&#xA;said nothing and left unpolled opinions. Nevertheless this summary is&#xA;informative as it feeds forwards into the design of proposals that will be&#xA;made prior to the Hong Kong workshop in December, in order that they have a&#xA;higher likelihood of success.&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150918/ddd28331/attachment.html&gt;</html></oembed>
