I was reading this article "Why Many Smart Contract Use Cases Are Simply Impossible" (here at coindesk.com) about how many ideas for smart contracts are impossible to implement in practice.
The author does not say that smart contracts are not useful for anything at all, but just that many of the ideas are not well suited for smart contracts.
He writes that
The problem with smart contracts isn’t just that people’s expectations are overblown, it's that these expectations are leading many to spend time and money on ideas that cannot possibly be implemented.
Over the past nine months, we've been pitched many smart contract use cases, and have found ourselves responding, time and again, that they simply cannot be done.
This made me think, are there any examples of successful implementations of smart contracts in use by any industry?
(I mean outside of the work smart contracts may do in the standard Ethereum network.)
