Blockchains began as shared, decentralized ledgers for cryptocurrencies and now support transactions in finance, healthcare, government and supply chains. In theory they tolerate faults.

What they work on
- Characterize dependencies across blockchain computing, storage and network resources to build a foundation for classifying faults that cause transaction data loss.
- Derive dependency-aware configuration models and prioritization algorithms that guide exploration of critical blockchain transaction states.
- Systematically and automatically test blockchain fault tolerance through principled scheduling and multidimensional complementary metrics, measuring both effectiveness and efficiency.
More about the research
In practice their complexity leaves transactions vulnerable to data loss. This project aims to close the gap between blockchain theory and how real systems behave.
Why it matters
More reliable blockchain transactions could protect against data loss in financial services, healthcare platforms, government records and supply chains that use these systems. Systematic fault-tolerance testing could increase confidence in adopting blockchains and inform the robustness of other large, mission-critical digital infrastructures.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
