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.
