Good point. As I understand it, the computations required for a blockchain
are significant, and there is a non-negligible cost (e.g. electricity). For
Bitcoin and other e-currencies, the folks who do the computations are
rewarded by getting Bitcoins (or other e-currencies).  So they are
compensated financially for the cost of the computations. But if the
blockchain is not used for a currency, how do you compensate the people that
perform the computations? That is, who pays for all the computing and all
the electricity?
