On the Performance of Cloud-based ARM SVE for Zero-Knowledge Proving Systems
Dumitrel Loghin, Shuang Liang, Shengwei Liu +3
Zero-knowledge proofs (ZKP) are becoming a gold standard in scaling blockchains and bringing Web3 to life. At the same time, ZKP for transactions running on the Ethereum Virtual Ma…
A Number Representation Systems Library Supporting New Representations Based on Morris Tapered Floating-point with Hidden Exponent Bit
Stefan-Dan Ciocirlan, Dumitrel Loghin
The introduction of posit reopened the debate about the utility of IEEE754 in specific domains. In this context, we propose a high-level language (Scala) library that aims to reduc…
Blockchain Goes Green? Part II: Characterizing the Performance and Cost of Blockchains on the Cloud and at the Edge
Dumitrel Loghin, Tien Tuan Anh Dinh, Aung Maw +3
While state-of-the-art permissioned blockchains can achieve thousands of transactions per second on commodity hardware with x86/64 architecture, their performance when running on d…
The Accuracy and Efficiency of Posit Arithmetic
Stefan Dan Ciocirlan, Dumitrel Loghin, Lavanya Ramapantulu +2
Motivated by the increasing interest in the posit numeric format, in this paper we evaluate the accuracy and efficiency of posit arithmetic in contrast to the traditional IEEE 754…
Understanding the Scalability of Hyperledger Fabric
Minh Quang Nguyen, Dumitrel Loghin, Tien Tuan Anh Dinh
The rapid growth of blockchain systems leads to increasing interest in understanding and comparing blockchain performance at scale. In this paper, we focus on analyzing the perform…
Communication-efficient Decentralized Machine Learning over Heterogeneous Networks
Pan Zhou, Qian Lin, Dumitrel Loghin +3
In the last few years, distributed machine learning has been usually executed over heterogeneous networks such as a local area network within a multi-tenant cluster or a wide area…
A Transactional Perspective on Execute-order-validate Blockchains
Pingcheng Ruan, Dumitrel Loghin, Quang-Trung Ta +3
Smart contracts have enabled blockchain systems to evolve from simple cryptocurrency platforms, such as Bitcoin, to general transactional systems, such as Ethereum. Catering for em…
Blockchains vs. Distributed Databases: Dichotomy and Fusion
Pingcheng Ruan, Tien Tuan Anh Dinh, Dumitrel Loghin +4
Blockchain has come a long way: a system that was initially proposed specifically for cryptocurrencies is now being adapted and adopted as a general-purpose transactional system. A…
5G: Agent for Further Digital Disruptive Transformations
Beng Chin Ooi, Gang Chen, Dumitrel Loghin +2
The fifth-generation (5G) mobile communication technologies are on the way to be adopted as the next standard for mobile networking. It is therefore timely to analyze the impact of…
The Disruptions of 5G on Data-driven Technologies and Applications
Dumitrel Loghin, Shaofeng Cai, Gang Chen +12
With 5G on the verge of being adopted as the next mobile network, there is a need to analyze its impact on the landscape of computing and data management. In this paper, we analyze…
Blockchain Goes Green? An Analysis of Blockchain on Low-Power Nodes
Dumitrel Loghin, Gang Chen, Tien Tuan Anh Dinh +2
Motivated by the massive energy usage of blockchain, on the one hand, and by significant performance improvements in low-power, wimpy systems, on the other hand, we perform an in-d…
