Efficient Static Analysis of Marlowe ContractsBut it is hard to predict how those ways of describing the properties affect the computational cost of verifying them..In this paper, we discuss what we learned while implementing and optimising the static analysis for Marlowe, a domain specific language for self-enforcing financial smart-contracts

Accurate Smart Contract Verification Through Direct Modellingin standard programming models. Still, the majority of reported smart contract verification projects either reuse off-the-shelf model checking tools resulting in inefficient and even unsound models, or apply generic solutions that typically require highly-trained human intervention. In this paper, w

On-Chain Forwards for Digital Assets collateral and settlement of payouts on expiry. Importantly, our framework also enables forwards to be traded without counterparty risk or reliance on off-chain assets (such as fiat currencies). To achieve this, we build on our previous work on on-chain options and demonstrate how the relevant math

Designing such analyzers, however, proved to be challenging and error-prone. We review the existing approaches to automated, sound, sta

Automated Verification of Embedded Control Softwareion. The development of such software is subject to tight time-to-market requirements, but at the same time also to very high safety requirements posed by various safety standards. To assure the latter, formal methods such as model-based testing and formal verification are increasingly used. However

From the CNL, a complete SysML specification is extracted, leveraging various forms of diagrams, and enabling automated code generation. Several formal verification methods are supported. A complementary p

Hybrid automata, in their various flavours, have been suggested as a formal model accurately capturing CPS dynamics and thus facilitating exhaustive behavioural analysis of interacting CPSes with mathematical rigour..In this a

Social capital is identified as symbolic common goods of a society, which foster the development of social trust and norms of reciprocity, which in turn leads to more

Cultural dilemmas and paradoxes are especially pronounced in organizations that operate in the context of wider social transformations. Such a context can hardly be explained by static cultural dimensions, which do not reflect its inherent complexity and contradictions. Observations a
