I am now working on blockchain technology, data security, and cryptography research at the School of Artificial Intelligence and Computer Science, Shaanxi Normal University (陕西师范大学人工智能与计算机学院). If you are seeking any form of academic cooperation, please feel free to email me at lxyang@snnu.edu.cn. We are hiring undergraduate interns!

I graduated from School of Computer Science and Technology, Xidian University (西安电子科技大学计算机科学与技术学院) with B.E. and Ph.D. degrees, advised by Yulong Shen (沈玉龙) and Xuewen Dong (董学文). I also collaborate with Yong Yu (禹勇) from Shaanxi Normal University, Xiaojiang Du (杜小江) from Stevens Institute of Technology and Zhiguo Wan (万志国) from Zhejiang Lab closely.

My research interest includes enhancing blockchain scalability while ensuring security, particularly PCN routing optimization for Layer 2, cross-shard transaction conflict resolution, and cross-chain data interaction. I have published 10+ papers at the top international conferences and journals such as IEEE INFOCOM, TC, ICDCS.

🚀 Blockchain Performance Optimization

ICDCS 2023

Optimal Hub Placement and Deadlock-Free Routing for Payment Channel Network Scalability, Lingxiao Yang, Xuewen Dong, Sheng Gao, Qiang Qu, Xiaodong Zhang, Wensheng Tian, Yulong Shen. | PDF | PPT

• This paper proposes a novel solution called ​​Splicer​​ to address key scalability challenges in Payment Channel Networks (PCNs). The core idea is to use multiple Payment Channel Hubs (PCHs), termed ​​smooth nodes​​, to optimize network load balancing and enable high-performance, deadlock-free routing.
• Splicer offers a comprehensive solution that tackles both ​​network scalability​​ (through optimal PCH placement) and ​​performance scalability​​ (through its novel routing protocol).

⛓️ Trusted Data Interaction

INFOCOM 2025

AsyncSC: An Asynchronous Sidechain for Multi-Domain Data Exchange in Internet of Things, Lingxiao Yang, Xuewen Dong, Zhiguo Wan, Sheng Gao, Wei Tong, Di Lu, Yulong Shen, Xiaojiang Du. | PDF | PPT

• This paper proposes ​​AsyncSC​​, a novel asynchronous sidechain framework designed to enable secure and efficient multi-domain data exchange for the Internet of Things (IoT). The key innovation is addressing the limitation of existing sidechain solutions that require synchronous network conditions, which are often impractical for resource-constrained and intermittently connected IoT devices. AsyncSC achieves high performance and security in asynchronous environments through a new cryptographic primitive and a transaction ordering mechanism.

📚 Scaling Blockchain via Sharding

TC 2025

HiCoCS: High Concurrency Cross-Sharding on Permissioned Blockchains, Lingxiao Yang, Xuewen Dong, Wei Wang, Sheng Gao, Qiang Qu, Wensheng Tian, Yulong Shen. | PDF | PPT

• This paper proposes ​​HiCoCS​, a novel scheme designed to handle the challenge of highly concurrent cross-shard transactions (CSTxs) in permissioned blockchains, specifically Hyperledger Fabric.

• HiCoCS is presented as the first solution to effectively solve the problem of highly concurrent CSTxs. It achieves this by cleverly leveraging existing platform features (composite keys) for conflict-free processing, combined with advanced cryptography (FHE) for privacy.
