Though some general things were thrown out, they were not\n\u003e\u003e\u003e extensively discussed nor agreed to. I personally think 2-4 is \"in\n\u003e\u003e\u003e range\", though 8 maybe not so much. Of course it depends on exactly\n\u003ehow\n\u003e\u003e\u003e the non-blocksize limit accounting/adjusting is done.\n\u003e\u003e\u003e\n\u003e\u003e\u003e Still, the \"greatest common denominator\" agreement did not seem to\n\u003ebe\n\u003e\u003e\u003e agreeing to an increase which continues over time, but which instead\n\u003e\u003e\u003e limits itself to a set, smooth increase for X time and then requires\n\u003ea\n\u003e\u003e\u003e second hardfork if there is agreement on a need for more blocksize\n\u003eat\n\u003e\u003e\u003e that point.\n\u003e\u003e\u003e\n\u003e\u003e\n\u003e\u003e Perhaps it is accurate to say that there wasn't consensus at all\n\u003eexcept\n\u003e\u003e that (1) we think we can work together on resolving this impasse\n\u003e(yay!),\n\u003e\u003e and (2) it is conceivable that changing from block size to some other\n\u003e\u003e metric might provide the basis for a compromise on near-term numbers.\n\u003e\u003e\n\u003e\u003e As an example, I do not think the net-UTXO metric provides any\n\u003ebenefit\n\u003e\u003e with respect to scalability, and in some ways makes the situation\n\u003eworse\n\u003e\u003e (even though it helpfully solves an unrelated problem of spammy dust\n\u003e\u003e outputs). But there are other possible metrics and I maintain hope\n\u003ethat\n\u003e\u003e data will show the benefit of another metric or other metrics\n\u003ecombined with\n\u003e\u003e net-UTXO in a way that will allow us to reach consensus.\n\u003e\u003e\n\u003e\u003e As a further example, I also am quite concerned about 2-4-8MB with\n\u003eeither\n\u003e\u003e block size or net-UTXO as the base metric. As you say, it depends on\n\u003ehow\n\u003e\u003e the non-blocksize limit accounting/adjusting is done... But if a\n\u003emetric\n\u003e\u003e were chosen that addressed my concerns (worst case propagation and\n\u003e\u003e validation time), then I could be in favor of an initial bump that\n\u003eallowed\n\u003e\u003e a larger number of typical transactions in a block.\n\u003e\u003e\n\u003e\u003e But where I really need to disagree is on the requirement for a 2nd\n\u003ehard\n\u003e\u003e fork. I will go on record as being definitively against this. While\n\u003ebeing\n\u003e\u003e conservative with respect to exponentials, I would very much like to\n\u003emake\n\u003e\u003e sure that there is a long-term growth curve as part of any proposal.\n\u003eI am\n\u003e\u003e willing to accept a hard-fork if the adopted plan is too\n\u003econservative, but\n\u003e\u003e I do not want to be kicking the can down the road to a scheduled 2nd\n\u003ehard\n\u003e\u003e fork that absolutely must occur. That, I feel, could be a more\n\u003edangerous\n\u003e\u003e outcome than an exponential that outlasts conservative historical\n\u003etrends.\n\u003e\u003e\n\u003e\u003e I commend Jeff for writing a Chatham-rules summary of the outcome of\n\u003esome\n\u003e\u003e hallway conversations that occurred. On the whole I think his summary\n\u003edoes\n\u003e\u003e represent the majority view of the opinions expressed by core\n\u003edevelopers at\n\u003e\u003e the workshop. I will caution though that on nearly every issue there\n\u003ewere\n\u003e\u003e those expressed disagreement but did not fight the issue, and those\n\u003ewho\n\u003e\u003e said nothing and left unpolled opinions. Nevertheless this summary is\n\u003e\u003e informative as it feeds forwards into the design of proposals that\n\u003ewill be\n\u003e\u003e made prior to the Hong Kong workshop in December, in order that they\n\u003ehave a\n\u003e\u003e higher likelihood of success.\n\u003e\u003e\n\u003e\u003e _______________________________________________\n\u003e\u003e bitcoin-dev mailing list\n\u003e\u003e bitcoin-dev at lists.linuxfoundation.org\n\u003e\u003e https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev\n\u003e\u003e\n\u003e\u003e\n\u003e\n\u003e\n\u003e-- \n\u003eI like to provide some work at no charge to prove my value.
