One question that has been lurking on my mind is - are these consensus
algorithms inherently unfair for nodes that are on high latency links? E.g.
if we have bitcoin mining nodes also in Chad - and most bitcoin
transactions happen in Russia, China and other parts in Europe - would
there be fairness in terms of earning mining revenue?
