Profile Cycle

Lingxiao Yang 杨凌霄

I am now working on blockchain technology, data security, and cryptography research at the School of Artificial Intelligence and Computer Science, Shaanxi Normal University . 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 Prof. Yulong Shen (沈玉龙) and Prof. Xuewen Dong (董学文). I also collaborate with Prof. Yong Yu (禹勇) from Shaanxi Normal University, Prof. Xiaojiang Du (杜小江) from Stevens Institute of Technology and Prof. 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, TSC, ICDCS.

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.

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.

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.

​AsyncSC​​'s 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.

HiCoCS: High Concurrency Cross-Sharding on Permissioned Blockchains

Lingxiao Yang, Xuewen Dong, Zhiguo Wan, Di Lu, Yushu Zhang, Yulong Shen.

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.
