Recent advances on blockchain for network and service management, publication date, december 2022, manuscript submission deadline, call for papers.

With the rapid adoption of new technologies and applications, e.g., Internet of Things, 5G/6G communication networks, big data analytics, and artificial intelligence, a deluge of devices are being connected to the network, thus generating a large amount of data. The collection, processing, and analysis of this vast amount of data is essential to help people and enterprises gain valuable information, make sensible decisions, and subsequently improve the quality of people’s lives. However, the underlying communication networks are thus facing a new number of un-precedented challenges. Managing these large number devices in a scalable and secure manner is bringing significant challenges to the infrastructure construction, maintenance, and management of the communication networks. Recurring data privacy breaches and the lack of control are making Internet users and enterprises less willing to provide valuable data for processing and analysis.

In recent years, the emergence of blockchain technology offers several salient features including decentralization, trust, immutability, and security that could address some of these safety, privacy, and transparency challenges. For example, the traceability of blockchain allows data to be recorded on the distributed ledgers from every step of collection and transaction, improve the quality of the data, and ensure the correctness of data analysis and mining. The decentralization of blockchain also offers a different perspective for device management in a communication network, as devices can establish and learn relationships with other devices. Thus, Distributed Ledger Technology (DLT) offers tremendous potential to disrupt all the industrial domains which involve coordination among autonomous resources. This includes finance technology (fintech) and payment systems (e.g., Bitcoin/Ethereum, SWIFT and Central Bank Digital Currencies), but also networks (e.g., power grids or telecom networks), computing (e.g., brokering of edge resources), IoT (e.g., supply chains or industry 4.0), and other service platforms (e.g., identity management).

The purpose of this Special Issue is to explore the research challenges in Blockchain technologies with a highlight in their promising capabilities to provide reliable and secure networked applications and services.

IEEE Transactions on Network and Service Management (IEEE TNSM)  is a premier journal for timely publication of archival research on the management of networks, systems, services, and applications. Following the success of the recent  TNSM  Special Issues on cybersecurity techniques for managing networked systems in 2020 and 2021, this Special Issue will focus on recent advances in network security management using DLT. We welcome submissions addressing the important challenges (see the non-exhaustive list of topics below) and presenting novel research or experimentation results. Survey papers that offer an insightful perspective on related work and identify key challenges for future research will be considered as well.  We look forward to your submissions!

IEEE Blockchain Tech Briefs - 2023

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

By Sergii Grybniak, Institute of Computer Systems, Odesa Polytechnic National University, Ukraine ; Yevhen Leonchyk, Faculty of Mathematics, Physics and Information Technologies, Odesa I.I. Mechnikov National University, Ukraine ; Igor Mazurok, Faculty of Mathematics, Physics and Information Technologies, Odesa I.I. Mechnikov National University, Ukraine ; Oleksandr Nashyvan, Institute of Computer Systems, Odesa Polytechnic National University, Ukraine ; and Alisa Vorokhta, Faculty of Mathematics, Physics and Information Technologies, Odesa I.I. Mechnikov National University, Ukraine

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.

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.
