 My research interests lie in distributed systems and security, with a focus on emerging technologies including blockchain systems, confidential computing, and AI agents. My goal is to build trustworthy distributed infrastructures that remain secure, scalable, confidential, and adaptive under increasingly dynamic and heterogeneous environments. Below are several representative research directions.
 
 ### Blockchain Performance and Security Analysis
-This project applies stochastic processes to analyze decentralized incentives and BFT consensus designs. Related analysis include selfish mining in Ethereum ([ICDCS'19](https://arxiv.org/abs/1901.04620)) and Bitcoin-NG ([Performance'20](https://arxiv.org/pdf/2001.05082.pdf)), chained HotStuff ([INFOCOM'21](https://arxiv.org/abs/2107.04947)/[TDSC'25]()),  Crystal (block withholding resilience, [TDSC'22](https://arxiv.org/abs/2312.00741)), Ethereum's private transactions ([ACSAC'24](https://jianyu-niu.github.io/)), chained BFT framework ([ToN'26](https://arxiv.org/pdf/2501.02970)/[TDSC'26](https://www.computer.org/csdl/journal/tq/5555/01/11592485/2hLQR8NLsUE)), Solana's PoH ([Security'26](https://www.usenix.org/conference/usenixsecurity26)).

 ###  Scalable BFT Consensus
 This project aims to design simple and scalable BFT consensus protocols. Related works include Hermes (structured transmission, [TDSC'21](https://ieeexplore.ieee.org/document/9543565)), EBFT (extreme simplicity, [TDSC'26]()/[Homepage](https://ebftalgorithm.github.io/)), Fast-HotStuff (robust chained BFT, [TDSC'23](https://arxiv.org/abs/2010.11454)), Stratus (shared mempool, [ICDE'23](https://github.com/gitferry/bamboo-stratus)), Ladon/Orthrus/Hydra (multi-BFT consensus, [EuroSys'25](https://arxiv.org/abs/2409.10954)/[ICDE'25](https://arxiv.org/abs/2501.14732)/[ICDE'26](https://arxiv.org/abs/2511.05843)), and Manta (asynchronous DAG, [NSDI'27]()).
