This article reminds me of this 'every technology we see today is subject to innovation and disruption. The MASS consensus engine called PoC is obviously superior than the bitcoin Pow consusus algorithm.
However, PoW has been in use for a long time, PoC is yet to be popular. As such we cannot conclude which is superior yet.
Of course there is no comparison b/w PoW with any other consensus algorithm. PoC is for new commers who want to start mining and dont have huge cash and expertise.
