This paper outlines key design principles of Scilla—an intermediatelevel language for verified smart contracts. Scilla provides a clean separation between the communication aspect of smart contracts on a blockchain, allowing for the rich interaction patterns, and a programming component, which enjoys principled semantics and is amenable to formal verification. Scilla is not meant to be a high-l...

This paper addresses the problem of development productivity on reconfigurable platforms. Due to the availability of generic low level tools and powerful logic synthesis tools, it becomes possible to define portable components that have both a high level behavior and attributes for physical synthesis. The behavior of a component can be fixed at compile time using concise specifications that wil...
