  The Problems of Consensus: An Ethical Inquiry into Democratic and Decentralized Principles.
  SpringerBriefs in Philosophy 2025 [Flyer, Book]

  A philosophical investigation that begins with a fundamental questions: "What does reaching agreement entail?" or "Why Vote?" In this project, I delve into the concept of consensus beyond computation, weaving together moral, ethical, epistemological, theological, societal, and technical perspectives into a unified dialogue. This book serves as a genuine call for reflection aimed at a two-fold audience of technologists and philosophers interested in technological-emerging ethical and social issues.

• [November 8, 2025] Our journey to rethink the design of consensus protocols began by entertaining the idea of speculative execution. We thought it would be an easy extension of known concurrency techniques in DB! Years later, we are excited to share our theoretical model to formally reason about speculation broadly.

  The proliferation of different BFT protocols has made it difficult to navigate the BFT landscape, let alone determine the protocol that best meets application needs. To this end, we propose Bedrock as a unified platform for BFT protocol analysis, implementation, and experimentation. Bedrock explores a design space consisting of a set of dimensions and explores several design choices that capture the trade-offs between different design space dimensions. Within Bedrock, a wide range of BFT protocols can be implemented and uniformly evaluated under a unified deployment environment.

  SpotLess (formerly known as PVP) is a practical concurrent rotational consensus protocol that entails (1) a chained rotational design that eliminates the traditional complex, error-prone view-change protocol; (2) a Rapid View Synchronization protocol that operates in general network conditions not limited to GST assumptions that recover earlier views without relying on the primary; (3) a high-performance concurrent consensus architecture over independent chained instances; (4) SpotLess outperforms state-of-the-art protocols, e.g., PBFT (by up to 430%), Narwhal-HS (by up to 137%), and HotStuff (by up to 3803%).
