Special Issue Information

Dear Colleagues,

The rapid evolution of distributed computing and blockchain technologies has transformed various sectors by enabling decentralized systems to enhance transparency, security, and efficiency. Distributed computing refers to a model in which computing resources are spread across multiple locations, allowing for collaborative processing and data sharing. Blockchain, as a specific implementation of distributed ledger technology, offers a secure method for recording transactions and ensuring data integrity.

This Special Issue aims to explore the latest advancements in distributed computing and blockchain technologies, focusing on their integration, applications, and implications for various domains. We invite original research articles, reviews, and case studies that address the latest theoretical developments, practical implementations, and challenges in these fields. Topics of interest include, but are not limited to, the following:

  • Novel architectures and algorithms for distributed computing.
  • Blockchain frameworks and their applications in real-world scenarios.
  • Scalability and performance optimization in distributed systems.
  • Security and privacy challenges in distributed computing and blockchain.
  • Interoperability between different blockchain platforms.
  • The use cases of blockchain in sectors such as finance, healthcare, supply chain, and IoT.
  • The role of smart contracts in distributed applications.
  • Governance and regulatory aspects of distributed and blockchain technologies.

Through this Special Issue, we aim to provide a platform for researchers and practitioners to share insights, foster collaboration, and advance their understanding of how distributed computing and blockchain can solve complex problems in an increasingly interconnected world.

With the widespread application of alliance chain technology in diverse scenarios, its immutability has gradually revealed certain limitations in practical use. To address this challenge, a redactable alliance chain innovatively introduces functionalities for data modification, deletion, and updating. However, issues related to redaction permissions, auditing, and security hinder its development. To overcome these challenges, the K-medoids clustering algorithm is first employed to select a redaction center and a consensus committee. The redaction center reviews redaction requests, while the consensus committee groups redaction blocks and reaches block consensus. Next, a dual-hash function scheme is proposed, where a subkey-updatable chameleon hash function collaborates with a standard hash function. The system’s master key can revoke a user’s redaction rights by updating their subkey. Based on this framework, a block redaction strategy comprising four phases and nine execution algorithms is introduced, enabling an auditable, accountable, and subkey-updatable RBAU. Security analysis and experimental results demonstrate that the proposed model excels in correctness, resistance to collision of the original key, resistance to collision of the updated key, user subkey updatability, and master key immutability. Additionally, the algorithm’s execution time, transaction execution time, block size, and redaction time are comparable to those of the pre-improvement alliance chain. Full article
