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

[Bitcoin-development] Max Block Size: Simple Voting Procedure

This is likely very similar to other proposals, but I want to bring voting procedures back into the discussion. The goal here is to create a voting procedure that is as simple as possible to increase the block size limit. Votes are aggregated over each 2016 block period. Each coinbase transaction

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

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 influentia

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 2
