I cannot believe why Gavin (who seems to have difficulty to spell my name correctly.) insists on his 20MB proposal regardless the community. BIP66 has been introduced for a long time and no one knows when the 95% goal can be met. This change to the block max size must take one year or more to be

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

Ignorant. You seem do not understand the current situation. We suffered from orphans a lot when we started in 2013. It is now your turn. Then please enlighten me. You're unable to download block templates from a trusted node outside of the country because the bandwidth requirements are too

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.

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

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

That orphan rate increase will go to whoever is producing the 20MB blocks, NOT you. This depends on how miners are connected. E.g. suppose there are three miners, A and B have fast connectivity between then, and C has a slow network. Suppose that A miners a block and B receives it in 1
