I fail to see how this is even relevant... are they trying to claim a small network making up about 10% of the total BTC hashrate has event he REMOTEST chance to outpace the 90% in block solutions... it is mathematically impossible... the 10% on average would only be able to generate blocks at this difficulty 1/10th as quickly as the main network...
Am I missing something here... or is that just a blatant oversight by the university? 10% of the hashrate cannot generate the same amount of blocks as 90% in the same time period at the same difficulty... paper debunked.
