Sommario
On May 26th, 2026, at 2:30 pm will we have a new seminar of DEEPSE Forum series titled "No More Surprises: Towards Explainable Blockchain Smart Contracts".Blockchain smart contracts automate and enforce agreements without intermediaries, yet their complexity poses significant challenges for human understanding, trust, and accountability. Despite widespread claims of transparency, users are routinely left without the information they need to understand what a contract does, why it behaves the way it does, or who is responsible when things go wrong. This seminar traces a research journey that builds the case for explainability as a fundamental design concern in smart contracts — one that has been largely overlooked. The journey begins by mapping the landscape of human-centric concerns in smart contracts, identifying explainability as a neglected dimension of trustworthy design. It then systematises existing knowledge on transparency, accountability, and understandability, revealing that smart contracts support visibility at the technical level but fall short where users need it most. Building on these foundations, the research introduces ExplanaSC, a framework that brings human-centred design, contract law principles, and Explainable AI practices together to determine what smart contracts should explain and why. The journey culminates in an empirical evaluation of real deployed contracts, using surprise as an analytical lens — where surprise signals a gap between what users expect and what the contract communicates. The findings show that missing justification, clarification, compliance, and consent information is not accidental; it is structural.
