This should bring us close to break even with the current fee size, but we should really get some empirical data for interconnected large pools. However - important note - if you are a 1% miner - don't include transactions! > > Q=0 -> f = 0.000042 BTC/kB Q=0.1 -> f = 0.000034 BTC/kB Q=0.25 > -> f = 0.000023 BTC/kB Q=0.40 -> f = 0.000015 BTC/kB > > > This problem is inherent to the fundemental design of Bitcoin: > regardless of what the blocksize is, or how fast the network is, > the current Bitcoin consensus protocol rewards larger mining pools > with lower costs per KB to include transactions. I don't see a problem of rewarding economy of scale, as long as the effect is not too grave (raising the min fee would actually make it more profitable for smaller miners).
