Please note: this post originally appeared on the Well-Typed blog.

TL;DR: A combination of formal modelling and testing using QuickCheck is a powerful tool in the design and implementation of high assurance software. Consistency of the model can be checked by testing invariants, and the real implementation can be tested by comparing it against the model.

As part of our consulting work for IOHK, Well-Typed have been working with IOHK on the design and implementation of the new version of the Cardano cryptocurrency wallet. As a crucial component of this process, we have written a semi-formal specification of the wallet: a mathematical model of the wallet along with…

In our previous blog post Cryptocurrencies need a safeguard to prevent another DAO disaster we discussed the need for high assurance development of cryptocurrencies and their underlying blockchain protocols. We also sketched one way in which one might go about this, but we did not give much detail. In this follow-up blog post we delve into computer science theory a bit more…
