I was also pointing this out to the people who were asking &#xA;me. A&#xA;commit to a personal repository does not at first seem more than&#xA;experimental. sipa commits weird/neat things to private branches all the&#xA;time, after all.&#xA;&#xA;&gt; to share behavior. In the case of mining, we&#39;re trying to optimize the&#xA;&gt; social good of POW security. (But the analogy applies in other ways &#xA;&gt; too:&#xA;&#xA;About the only argument IMO in favour of block size increases is to &#xA;assume&#xA;that making more room in a block will make it attractive to use for more&#xA;people at some point in the future: increasing transaction velocity,&#xA;increasing economy size, increasing value overall.&#xA;&#xA;&gt; increases to the chain side are largely an externality; miners enjoy &#xA;&gt; the&#xA;&gt; benefits, everyone else takes the costs--either in reduced security or&#xA;&gt; higher node operating else.)&#xA;&#xA;Who else but miners and pool operators will run full nodes when full &#xA;nodes&#xA;are being shut down because they are too large and unwieldy to maintain? &#xA;It&#xA;is already so that casual users refuse to run full nodes. This fact is&#xA;indisputable. The only question remaining is, &#34;Do we care?&#34; Arguments&#xA;against users who feel that the dataset is too large to run a full node,&#xA;full-time, start from a premise that these users are a static and &#xA;irrelevant&#xA;fraction. Is this even true? &#34;Do we care?&#34; I do. I will shortly only be &#xA;able&#xA;to run half the nodes I currently do thanks to the growth of the &#xA;blockchain&#xA;at its current rate.&#xA;&#xA;&gt; One potential argument is that maybe miners would be _regulated_ to&#xA;&gt; behave correctly. But this would require undermining the openness of &#xA;&gt; the&#xA;&gt; system--where anyone can mine anonymously--in order to enforce &#xA;&gt; behavior,&#xA;&gt; and that same enforcement mechanism would leave a political level to&#xA;&gt; impose additional rules that violate the extra properties of the &#xA;&gt; system.&#xA;&#xA;I would refuse to mine under such a regulated regime; moreover, I would&#xA;enjoy forking away from this, and, I suspect, the only miners who remain&#xA;would be those whose ultimate motivations do not coincide with the &#xA;users.&#xA;That is, the set of miners who are users, and the set of users who are&#xA;miners, would be wholly non-intersecting.&#xA;&#xA;&gt; So far the mining ecosystem has become incredibly centralized over &#xA;&gt; time.&#xA;&#xA;This is unfortunate but true.&#xA;&#xA;&gt; of the regular contributors to Bitcoin Core do. Many participants&#xA;&gt; have never mined or only did back in 2010/2011... we&#39;ve basically&#xA;&gt; ignored the mining ecosystem, and this has had devastating effects,&#xA;&gt; causing a latent undermining of the security model: hacking a dozen or&#xA;&gt; so computers--operated under totally unknown and probably not strong&#xA;&gt; security policies--could compromise the network at least at the tip...&#xA;&#xA;The explicit form of the block dictated by the reference client and&#xA;agreed-to by the people who were sold on bitcoin near the beginning &#xA;(myself&#xA;included) was explicitly the notion that the rules were static; that the&#xA;nature of transaction foundations and the subsidies would not be &#xA;altered.&#xA;Here we have a hardfork being contemplated which is not only &#xA;controversial,&#xA;but does not even address some of the highest-utility and most-requested&#xA;features in peoples&#39; hardfork wishlists.&#xA;&#xA;The fact that mining has effectively been centralized directly implies &#xA;that&#xA;destabilizing changes that some well-heeled (and thus theoretically &#xA;capable,&#xA;at least) people have explicitly begun plans to fork the blockchain &#xA;about&#xA;will have an unknown, and completely unforeseen combined effect.&#xA;&#xA;We can pretend that, &#34;If merchants and miners and exchanges go along, &#xA;then&#xA;who else matters,&#34; but the reality is that the value in bitcoin exists&#xA;because *people* use it for real transactions: Not miners, whose profits &#xA;are&#xA;parasitically fractionally based on the quality and strength of the &#xA;bitcoin&#xA;economy as a whole; not exchanges who lubricate transactions in service &#xA;to&#xA;the economy; not even today&#39;s merchants whose primary means of accepting&#xA;bitcoin seems to be to convert them instantly to fiat and not &#xA;participate&#xA;meaningfully in the economy at all; not enriched felons; but actual &#xA;users&#xA;themselves.&#xA;&#xA;&gt; Rightfully we should be regarding this an an emergency, and probably&#xA;&gt; should have been have since 2011.&#xA;&#xA;There are two ways to look at it, assuming that the blocksize change&#xA;increases bitcoin&#39;s value to people after all: mining centralization &#xA;will be&#xA;corrected; or, mining centralization will not be corrected.&#xA;&#xA;I would argue that rapidly increasing profitability at this point will&#xA;exacerbate the mining centralization problem, and in much the same way &#xA;as&#xA;when people were throwing money and unknowingly funding the massive &#xA;frauds&#xA;of the current cabals when bitcoin&#39;s exchange-driven rise to $1200 was &#xA;first&#xA;realized.&#xA;&#xA;Thus, even if the premise were true, what will a blocksize increase &#xA;achieve&#xA;given mining centralization itself is a bigger systemic risk?&#xA;&#xA;&gt; Hardfork changes should only be made if they&#39;re almost completely&#xA;&gt; uncontroversial--where virtually everyone can look at the available &#xA;&gt; data&#xA;&gt; and say &#34;yea, that isn&#39;t undermining my property rights or future use&#xA;&gt; of Bitcoin; it&#39;s no big deal&#34;.&#xA;&#xA;The recent &#34;revelation&#34; that there are masses of paid trolls on popular&#xA;forum sites like reddit who supposedly don&#39;t even know who is hiring &#xA;them,&#xA;and the anger of more vociferous commenters in general, does not &#xA;invalidate&#xA;the relevance of every non-&#34;industry&#34; voice.  I think elevating the&#xA;discussion away from the users does the system and the development &#xA;process&#xA;as a whole quite an injustice.&#xA;&#xA;&gt; I&#39;m curious as to what discussions people have seen; e.g., are people&#xA;&gt; even here aware of these concerns? Are you aware of things like the&#xA;&gt; hashcash mediated dynamic blocksize limiting?&#xA;&#xA;I have seen most of these; or the ideas seem obvious based on their &#xA;names.&#xA;&#xA;&gt; About proposals like lightning network (instant transactions and &#xA;&gt; massive&#xA;&gt; scale, in exchange for some short term DOS risk if a counterparty opts&#xA;&gt; out)? Do people (other than Mike Hearn; I guess) think a future where&#xA;&gt; everyone depends on a small number of &#34;Google scale&#34; node operations &#xA;&gt; for&#xA;&gt; the system is actually okay? (I think not, and if so we&#39;re never going &#xA;&gt; to&#xA;&gt; agree--but it can be helpful to understand when a disagreement is&#xA;&gt; ideological).&#xA;&#xA;It is not okay. If the current mining cabals continue to exist, and&#xA;flourish, and the developers make major changes that ignore this glaring&#xA;elephant, then the decentralized promise of bitcoin will be put more at&#xA;risk.&#xA;&#xA;signmessage 1DdcrjT9Yqb6U58wVMA2e7untFbz2rmZd4 &#xA;&#34;49786791f4d0a260689867ccdfb2cc5b8460984e335504444ade113d2768505c&#34;&#xA;G6NPl7Wklo9lcdgeVI2H2pexzgqD0KPHhI/wAe32DBm8m59Qf31j5d4tsx5drcql/8wPeIb0QGarr/o4VIOLLGE=&#xA;&#xA;--[remove this line and below]--&#xA;HHsTfiZ/S7+GNYRwws+QyAr+6/MgDz0Jyntl7CAvjhdfzbnwPorybQUXxRw3CE4DgYgAy1zLanE8H/5NK+l3UlE=</html></oembed>
