Atsuki Momose

I am a Research Engineer at Acompany, a privacy-tech startup based in Japan. We are building a secure, regulation-compliant enterprise data collaboration platform leveraging confidential computing techniques.

I am also working as an independent researcher (affiliated with my own firm, Quitee LLC) primarily on developing MPC for blockchains. Previously, I was a visiting research scholar and a PhD student in Computer Science at the University of Illinois Urbana-Champaign.

I sincerely appreciate the generous grant from the Ethereum Foundation for my ongoing research in asynchronous MPC. I am honored to have received the Tsujii Shigeo Security Paper Award (2022) and the Illinois Distinguished Fellowship.

I am selected as a program committee member for ACM CCS 2024.

Research.

I am generally interested in distributed computing and cryptography.

Blockchain Consensus.

Distributed consensus is an underlying technology of Bitcoin, often referred to as blockchain. Consensus is a decade-old problem, and Bitcoin is often considered just another solution to the classical problem. However, Bitcoin’s consensus mechanism takes a completely different approach from classic solutions, and it comes with several unique features, such as support for dynamic participation, higher fault tolerance under asynchronous clocks, and efficient communication through the use of sparse gossip networks. My interest is exploring the intersection of Bitcoin and classic solutions aiming to achieve the best of both worlds. Here are some of my recent works.

Distributed Cryptography.

I am recently expanding my research interest to cryptography for distributed computing.
