IEEE Blockchain Technical Briefs - 2023
A collection of short technical articles

Welcome to IEEE Blockchain Technical Briefs 2023 Edition!

Message from Dr. Justin Y. Shi, 2023 Editor in Chief

Blockchain technology is an exciting technology with many controversies. It is commonly accepted that it has the potential to transform existing technologies to a higher ground. Realizing this potential, however, would require overcoming some significant hurdles. The Editorial Board wishes to bring four such challenges for this year’s publication.

A Peek into the Blockchain Technology Developments

By Justin Y. Shi, PhD, Associate Professor of CIS Department, College of Science and Technology, Temple University, USA

Known as Distributed Ledger Technology or DLT, blockchain can store transaction ledgers on networked, geographically dispersed computers securely and reliably in perpetuity. It is best known for its role in cryptocurrency systems, but it is also desirable in a wide range of other applications, such as health records, supply-chain management, elections, and many others. Distributed databases are a type of centralized DLT that have failed to scale. Eliminating database service downtimes and arbitrary transaction losses has been proven to be very difficult if not impossible to accomplish [1].

Blockchain is a new type of decentralized DLT that is also difficult to scale. Blockchain technology enables decentralized ledger processing without central authority using step-locked cryptographic proofs [2]. Since transactions are approved by anonymous computers, authenticating them correctly and processing them securely are the two top priorities while performance is of secondary concern. Indeed, finding a balance between these priorities – decentralization, security, and stability – is inherently difficult and is often referred to as the “Blockchain trilemma”.


Dynamic Bandwidth Adjusting in BlockDAG Networks

This work presents a mechanism for dynamically adapting a decentralized network to fluctuations in transaction flow, based on a directed acyclic graph (DAG) ledger structure. By incorporating this approach, a system can effectively respond to changing network workloads, ensuring a self-sufficient and adaptive environment for processing a transaction throughout its entire lifespan. Although this dynamic adoption mechanism is designed explicitly for the current version of the Waterfall platform, the presented approach possesses the potential to be applied across a wide range of networks built on the blockDAG principle, owing to a set of tuning parameters.

Improving e-Commerce and Electronic Auction Systems by using Blockchain and Machine learning technologies is an innovative national Romanian research project that aims to transform the online shopping experience by incorporating unique features such as subscriptions, auctions, smart contracts and artificial intelligence. This article presents the use of Blockchain for this innovative project.


Case Study: Uttarakhand State Medical College Blockchain Based Asset Management

By Sristhi Assudani, IEEE APAC Blockchain Region Lead; Akhilesh Srivastava, IT Advisor Uttarakhand Government

Health care is one industry where blockchain is expected to have significant impacts. Health care asset management faces limitations in leveraging advanced analytics and new sources of unstructured fragmented data (history, lab, socioeconomic, demographics, equipment data, patient data) as well as system interoperability and accessibility of medical records. The healthcare sector has large deployments of critical assets which must be available at the right place at the right time. This necessitates not only the locations of the assets being monitored in real time but also serviceability being ensured through predictive maintenance. The data can be aggregated and analyzed for meaningful inferences about the monitored process and assets. The asset information is critical both for privacy preservation and tamper proofing. Health care systems are overly complex and fragmented, and use multiple information technology systems, incorporating different standards for similar or same systems. To be meaningful, the health record of an individual needs to be from conception or birth. As one progresses through one’s life, every record of every clinical encounter represents an event in one's life. Each of these records may be significant or insignificant depending on the current problems that the person suffers from. Thus, it becomes imperative that these records be arranged chronologically to provide a summary of the various clinical events in the lifetime of a person.
