Hi I made these comments elsewhere, but I think really we should be having these kind of conversations here rather than scattered around.
These are about Jeff Garzik's outline draft BIP 100 I guess this is the latest draft: (One good thing about getting off SF would be finally JGarzik's emails actually not getting blocked!). http://gtf.org/garzik/bitcoin/BIP100-blocksizechangeproposal.pdf may have changed since the original [1] Over the original proposal: 1. there should be a hard cap, not indefinitely growing. 2. there should be a growth limiter (no more than X%/year) 3. I think the miners should not be given a vote that has no costs to cast, because their interests are not necessarily aligned with users or businesses. I think Greg Maxwell's difficulty adjust [2] is better here for that reason. It puts quadratic cost via higher difficulty for miners to vote to increase block-size, which miners can profitably do if there are transactions with fees available to justify it. There is also the growth limiter as part of Greg's proposal. [3] I think bitcoin will have to involve layering models that uplift security to higher layers, but preserve security assurances, and smart-contracts even, with protocols that improve the algorithmic complexity beyond O(n^2) in users, like lightning, and there are multiple other candidates with useful tradeoffs for various use-cases. One thing that is concerning is that few in industry seem inclined to take any development initiatives or even integrate a library. I suppose eventually that problem would self-correct as new startups would make a more scalable wallet and services that are layer2 aware and eat the lunch of the laggards. But it will be helpful if we expose companies to the back-pressure actually implied by an O(n^2) scaling protocol and don't just immediately increase the block-size to levels that are dangerous for decentralisation security, as an interventionist subsidy to save them having to do basic integration work. Otherwise I think whichever any kind of kick the can some 2-5 years down the road we consider, we risk the whole saga repeating in a few years, when no algorithmic progress has been made and even more protocol inertia has set in.
