Typing Fallback Functions: A Semantic Approach to Type Safe Smart Contracts
Stian Lybech, Daniele Gorla, Luca Aceto
This paper develops semantic typing in a smart-contract setting to ensure type safety of code that uses statically untypable language constructs, such as the fallback function. The…
A Sound Type System for Secure Currency Flow
Luca Aceto, Daniele Gorla, Stian Lybech
In this paper we focus on TinySol, a minimal calculus for Solidity smart contracts, introduced by Bartoletti et al. We start by rephrasing its syntax (to emphasise its object-orien…
Monitorability for the Modal mu-Calculus over Systems with Data: From Practice to Theory
Luca Aceto, Antonis Achilleos, Duncan Paul Attard +4
Runtime verification, also known as runtime monitoring, consists of checking whether a system satisfies a given specification by observing the trace it produces during its executio…
Centralized vs Decentralized Monitors for Hyperproperties
Luca Aceto, Antonis Achilleos, Elli Anastasiadi +3
This paper focuses on the runtime verification of hyperproperties expressed in Hyper-recHML, an expressive yet simple logic for describing properties of sets of traces. To this end…
