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

Yes, if you are on a slow network then you are at a (slight) disadvantage. So? Chun mentioned that his pool is on a slow network, and thus bigger blocks give it an disadvantage. (Orphan rate is proportional to block size.) You said that no, on contrary those who make big blocks have a

Aren't you calculating bandwidth for a singly-connected node? A highly connected miner could have 30-100 node connections so you probably need to increase your traffic estimates by that factor. I.e. For 100MB blocks, 30-100 Mbps and $60-$100 per day data costs. You should be able to handle

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

I will abstain on this wrangle of when, Instead I'd like to address some of the network topology health issues that's been brought up in this debate. Due to how blocks are being broadcast by miners at the moment, it is not difficult to find the origin node of these blocks. These more influential

Whatever...let's use the current subsidies, the same argument applies, it's just 20 + 25 = 45 btc per block for miner B vs 27 btc for miner B. Miner B would still go out of business, bigger blocks still mean more mining and validation centralization. The question is how far I we willing to go with
