  Two of the most important technological advancements currently underway are
the advent of quantum technologies, and the transitioning of global financial
systems towards cryptographic assets, notably blockchain-based cryptocurrencies
and smart contracts. There is, however, an important interplay between the two,
given that, in due course, quantum technology will have the ability to directly
compromise the cryptographic foundations of blockchain. We explore this complex
interplay by building financial models for quantum failure in various
scenarios, including pricing quantum risk premiums. We call this quantum
crypto-economics.
