Time Is Money: Incentivized Causal Transaction Ordering
Hongyin Chen, Xu Zheng, Jichen Li +1
Front-running is a subtle and persistent problem for blockchains. A blockchain is a stateful virtual machine executing instructions called transactions. Users earn rewards by publi…
Incentivizing Data Trading via Profit Reallocation
Yunxuan Ma, Wu Xin, Jichen Li +5
Data trading is a central approach to data circulation, yet data markets remain far less active than expected. A primary bottleneck is the lack of effective economic incentives. Ex…
Survey on Strategic Mining in Blockchain: A Reinforcement Learning Approach
Jichen Li, Lijia Xie, Hanting Huang +5
Strategic mining attacks, such as selfish mining, exploit blockchain consensus protocols by deviating from honest behavior to maximize rewards. Markov Decision Process (MDP) analys…
Sealed-bid Auctions on Blockchain with Timed Commitment Outsourcing
Jichen Li, Yuanchen Tang, Jing Chen +2
Sealed-bid auctions play a crucial role in blockchain ecosystems. Previous works introduced viable blockchain sealed-bid auction protocols, leveraging timed commitments for bid enc…
MEV Makes Everyone Happy under Greedy Sequencing Rule
Yuhao Li, Mengqian Zhang, Jichen Li +3
Trading through decentralized exchanges (DEXs) has become crucial in today's blockchain ecosystem, enabling users to swap tokens efficiently and automatically. However, the capacit…
Budget-Constrained Auctions with Unassured Priors: Strategic Equivalence and Structural Properties
Zhaohua Chen, Mingwei Yang, Chang Wang +5
In today's online advertising markets, it is common for advertisers to set long-term budgets. Correspondingly, advertising platforms adopt budget control methods to ensure that adv…
Insightful Mining Equilibria
Mengqian Zhang, Yuhao Li, Jichen Li +2
The selfish mining attack, arguably the most famous game-theoretic attack in blockchain, indicates that the Bitcoin protocol is not incentive-compatible. Most subsequent works main…
An Efficient and Robust Committee Structure for Sharding Blockchain
Mengqian Zhang, Jichen Li, Zhaohua Chen +2
Nowadays, sharding is deemed as a promising way to save traditional blockchain protocols from their low scalability. However, such technique also brings several potential risks and…
An Efficient Permissioned Blockchain with Provable Reputation Mechanism
Hongyin Chen, Zhaohua Chen, Yukun Cheng +5
The design of permissioned blockchains places an access control requirement for members to read, access, and write information over the blockchains. In this paper, we study a hiera…
CycLedger: A Scalable and Secure Parallel Protocol for Distributed Ledger via Sharding
Mengqian Zhang, Jichen Li, Zhaohua Chen +2
Traditional public distributed ledgers have not been able to scale-out well and work efficiently. Sharding is deemed as a promising way to solve this problem. By partitioning all n…
