The term Smart Contracts refers to a set of technologies that – broadly
speaking – enable execution of code on blockchains. Many business
processes have already been mapped on such contracts, with Ethereum
being a popular platform. But since smart contracts are code, we have to
ask ourselves about ensuring code quality. Testing is certainly a useful
tool for that, but given that smart contracts handle millions of
dollars, is it enough? This talk will give an introduction into formal
verification and present an overview over the state of the art in the
blockchain space.
