An Algebraic-Topological Approach to Processing Cross-Blockchain Transactions
Dongfang Zhao
The state-of-the-art techniques for processing cross-blockchain transactions take a simple centralized approach: when the assets on blockchain , say -coins, are exchanged wit…
Trustworthy Edge Computing through Blockchains
Abdullah Al-Mamun, Dongfang Zhao
Edge computing draws a lot of recent research interests because of the performance improvement by offloading many workloads from the remote data center to nearby edge nodes. Noneth…
Fork-Resilient Cross-Blockchain Transactions through Algebraic Topology
Dongfang Zhao
The cross-blockchain transaction (CBT) serves as a cornerstone for the next-generation, blockchain-based data management systems. However, state-of-the-art CBT models do not addres…
Toward Equilibria and Solvability of Blockchain Pooling Strategies: A Topological Approach
Dongfang Zhao
In 2015, Eyal proposed the first game-theoretical model for analyzing the equilibrium of blockchain pooling: when the blockchain pools are abstracted as a non-cooperative game, two…
Topological Properties of Multi-Party Blockchain Transactions
Dongfang Zhao
The cross-blockchain transaction remains one of the most challenging problems in blockchains. The root cause of the challenge lies in the nondeterministic nature of blockchains: A…
Distributed Cross-Blockchain Transactions
Dongfang Zhao, Tonglin Li
The interoperability across multiple or many blockchains would play a critical role in the forthcoming blockchain-based data management paradigm. In particular, how to ensure the A…
SciChain: Trustworthy Scientific Data Provenance
Abdullah Al-Mamun, Dongfang Zhao
The state-of-the-art for auditing and reproducing scientific applications on high-performance computing (HPC) systems is through a data provenance subsystem. While recent advances…
BAASH: Enabling Blockchain-as-a-Service on High-Performance Computing Systems
Abdullah Al-Mamun, Dongfang Zhao
The state-of-the-art approach to manage blockchains is to process blocks of transactions in a shared-nothing environment. Although blockchains have the potential to provide various…
Distributed Nonblocking Commit Protocols for Many-Party Cross-Blockchain Transactions
Xinying Wang, Olamide Timothy Tawose, Feng Yan +1
The interoperability across multiple blockchains would play a critical role in future blockchain-based data management paradigm. Existing techniques either work only for two blockc…
The Blockchain Game: Synthesis of Byzantine Systems and Nash Equilibria
Dongfang Zhao
This position paper presents a synthesis viewpoint of blockchains from two orthogonal perspectives: fault-tolerant distributed systems and game theory. Specifically, we formulate a…
BlockLite: A Lightweight Emulator for Public Blockchains
Xinying Wang, Abdullah Al-Mamun, Feng Yan +2
Blockchain is an enabler of many emerging decentralized applications in areas of cryptocurrency, Internet of Things, smart healthcare, among many others. Although various open-sour…
Comparative Evaluation of Big-Data Systems on Scientific Image Analytics Workloads
Parmita Mehta, Sven Dorkenwald, Dongfang Zhao +7
Scientific discoveries are increasingly driven by analyzing large volumes of image data. Many new libraries and specialized database management systems (DBMSs) have emerged to supp…
