Decentralized Systems Group at Yale
Decentralized Systems enabled by Internet-scale consensus and cryptography can enable transformative applications with strong security, privacy, resiliency, and fairness guarantees. We work on fundamental technical problems to advance this vision.
Research
Our research aims to address the security, scalability, and incentive compatibility challenges of decentralized systems.
Select recent projects are:
- Prooφ: a transaction fee mechanism for ZK Rollups
- zkBridge: trustless cross-chain interoperability using SNARKs.
- Mempool Guru: an open public service that persists Ethereum mempool data for research.
- DECO: proving TLS data provenance while protecting privacy.
