Supporting distributed data management applications among a set of mutually distrustful collaborative enterprises has emerged as a key requirement for today’s large-scale data management systems. While Blockchain was originally devised for Bitcoin cryptocurrency, recent systems focus on its unique features such as provenance, fault tolerance, verifiability, and authenticity to support a wide range of applications.
The goal of this project is to address different challenges regarding the confidentiality, verifiability, performance, and scalability requirements of distributed applications to make permissioned blockchain systems practical in real-life settings.
The project itself consists of several sub-projects to address different challenges.
- Saguaro: a hierarchical permissioned blockchain system designed specifically for wide area networks, optimized to take advantage of edge computing infrastructures and support edge devices’ mobility.
- Qanaat: a scalable multi-enterprise permissioned blockchain system that guarantees the confidentiality of enterprises within and across collaboration workflows.
- TetrisChains: a novel disaggregated blockchain service that leverages recent innovations in disaggregated data centers (DDC)
- PVL: a framework to support privacy-preserving data provenance using zero-knowledge proofs over hybrid permissioned ledgers.
- GBFT: A unified platform for Byzantine fault-tolerant protocols design exploration
