Oh, well, Denmark and sugar beets then :) The paper shows a practical use of secret sharing and secure multiparty computation to discover the market price of a commodity. Not sure how secure it is, but it's interesting. It's not the same thing as securing consensus of a blockchain ledger. In the paper they have over a thousand participants and 3 (or some small number of) servers. In the blockchain problem, each participant runs his own server. The fault tolerance model is different, and also the blockchain requires continuous consensus.
