Beyond the hype of blockchain, a look at its reality

Cryptocurrencies do make valid use cases for blockchains, though the political decentralisation of the participants involved is questionable.

Blockchain is a fascinating data structure that generates great curiosity in computer science, the social and political sciences, and public policy. However, there is a lot of hype around the concept and its adoption in diverse fields seems to be faith-based, driven by unsubstantiated vendor and consultant claims. This is both bewildering and risky and stems, perhaps, from an inadequate understanding of the blockchain properties as well as imprecise articulations of their application requirements.
