This book constitutes the thoroughly refereed workshop proceedings of the 8th International Workshop on Structured Object-Oriented Formal Language and
Method, SOFL+MSVL 2018, held in Gold Coast, QLD, Australia, in November 2018.
The 11 revised full papers included in the volume were carefully reviewed and selected from 21 submissions. They are organized in the following topical sections: programming and testing; verification and validation; semantics; and blockchain.
We have been longing for a process of software construction that can timely indi-

the possible future contents of the software towards its error-free completion,
simply because it can significantly improve software quality, reduce construction
cost, and enhance software productivity.
