Re: [Bitcoin-development] Fwd: Block Size Increase Requirements

So lets rephrase that and say instead more correctly it is the job of miners (collectively) to be well connected globally - and indeed there are incentivised to be or they tend to receive blocks at higher latency and so are at increased risk of orphans. And miner groups with good block latency in-

Re: [Bitcoin-development] Fwd: Block Size Increase Requirements

I don't see this as an issue of sensitivity or not. Miners are businesses that sell a service to Bitcoin users - the service of ordering transactions chronologically. They aren't charities. If some miners can't provide the service Bitcoin users need any more, then OK, they should not/cannot mine.

Nielsen's Law of Internet Bandwidth is simply not true, but if you look at data points like http://www.netindex.com/upload/ which will show we are at least on the right track, but this is flawed still. The fact of the matter is these speed tests are done from local origin to local destination wit

Re: [Bitcoin-development] Fwd: Block Size Increase Requirements

I'm OK with a smaller size + a formula that ramps it up over time. We are far from having enough demand to fill 10MB blocks, let alone 20MB today. To put it in perspective, to be feeling squeezed inside 10MB within two years, we would need to double usage five times. I wish I knew a way to make th

That is good. I oppose 20MB because I estimate it may increase the overall orphan rate to an unacceptable level. 5MB, 8MB or probably 10MB should be ok. On Mon, Jun 1, 2015 at 9:59 PM, Gavin Andresen wrote: > On Mon, Jun 1, 2015 at 7:20 AM, Chun Wang <1240...@gmail.com> wrote: >> >> I cannot beli

I cannot believe why Gavin (who seems to have difficulty to spell my name correctly.) insists on his 20MB proposal regardless the community.

He also said that the equation for miners has many variables, as it should. There is no disadvantage if the network speed is the same between the miners. If there is a difference in network speed, the miner is incentivized to invest in their network infrastructure. 2015-05-31 23:55 GMT+01:00 Alex
