Special Issue Information

Dear Colleagues,

The convergence of blockchain and big data analytics is driving innovation across a wide range of digital ecosystems. Blockchain offers decentralized trust, transparency, and tamper-resistant data management, while big data analytics provides the capability to extract insights from large, dynamic, and diverse datasets. Their integration presents new opportunities for secure, scalable, and intelligent systems across a wide range of sectors such as finance, healthcare, supply chains, and smart cities.

This Special Issue aims to collect high-quality research articles, reviews, and case studies that address the technical challenges and breakthroughs in this area. Topics of interest include blockchain-based frameworks for data integrity and access control, smart contracts, privacy-preserving analytics in decentralized environments, consensus mechanisms adapted for high-throughput data settings, and the use of AI/ML models in blockchain-enhanced applications. We also encourage submissions that explore system-level designs involving sensor data, risk analysis, and secure data sharing, particularly those that relate to complex and data-intensive applications.

Topics of interest include, but are not limited to, the following:

  • Blockchain;
  • Smart contracts;
  • Big data analytics;
  • Distributed Ledger Technology (DLT);
  • AI and blockchain integration;
  • Autonomous vehicles security using blockchain;
  • Privacy-preserving computation;
  • Secure data sharing;
  • Decentralized Applications (dApps);
  • Federated learning;
  • Data provenance;
  • Cybersecurity;
  • Risk analysis in decentralized systems;
  • Real-time data processing;
  • Multi-sensor fusion;
  • Secure V2X communication;
  • IoT and blockchain;
  • Blockchain scalability;
  • Consensus mechanisms;
  • Edge intelligence.

One of the main problems faced by database administrators for optimizing analytic workloads is fragmentation. Therefore, in recent decades, several fragmentation methods for analytical platforms have been proposed because this technique is able to improve the performance of OLAP (Online Analytical Processing) queries. In this study, we conducted an exploratory review of horizontal fragmentation methods for analytical repositories such as data warehouses, data lakes, and data lakehouses. This study presents a scoping review conducted using Arksey and O’Malley’s methodological framework and reported according to the PRISMA guidelines, covering 58 primary studies on horizontal fragmentation published from 2015 to 2025. Our analysis focuses on five aspects: (1) determining the main techniques used in horizontal fragmentation works for analytical repositories, (2) the classification of these studies, (3) the performance metrics considered when evaluating the horizontal fragmentation scheme, (4) the information type indexed by the repositories, and (5) the technologies most used by the approaches. Our findings suggest that horizontal fragmentation is a good opportunity to improve the performance of analytical workloads in most cases. The results of this scoping review will provide important guidelines for future research on horizontal fragmentation methods. In addition, the results will provide clues about the use of OLAP technologies for professionals and academics considering future directions. Full article
