New Trends for Blockchain Technology in IoT

Dear Colleagues,

The Internet of Things (IoT) has revolutionized connectivity across industries, enabling seamless data exchange among billions of devices in smart cities, industrial systems, healthcare, and beyond. However, this rapid expansion brings critical challenges, including data security vulnerabilities, privacy risks, lack of trust in decentralized networks, and scalability limitations. Blockchain technology, with its inherent features of decentralization, immutability, and cryptographic security, has emerged as a transformative solution to address these gaps, fostering secure, transparent, and trustless interactions in IoT ecosystems. As research at the intersection of blockchain and IoT advances, new trends—such as edge-integrated blockchain architectures, lightweight consensus mechanisms, and cross-domain interoperability—are reshaping the landscape, demanding a deeper exploration of their potential and limitations.

We are pleased to invite you to contribute to this Special Issue of Electronics, entitled "New Trends for Blockchain Technology in IoT." This Special Issue aims to showcase cutting-edge research that explores emerging paradigms, innovative applications, and technical breakthroughs at the confluence of blockchain and IoT. By bringing together original findings and comprehensive reviews, we seek to advance theoretical understanding, address practical challenges, and guide future directions for this dynamic field.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Lightweight blockchain protocols for resource-constrained IoT devices;
• Privacy-preserving data sharing in blockchain-enabled IoT networks;
• Scalable consensus mechanisms tailored for large-scale IoT deployments;
• Interoperability frameworks for cross-platform blockchain–IoT systems;
• Edge computing and blockchain integration for low-latency IoT applications;
• Blockchain-based identity management and access control in IoT;
• Real-world use cases (e.g., industrial IoT, smart healthcare, supply chain IoT) leveraging blockchain;
• Security audits and vulnerability mitigation in blockchain–IoT ecosystems.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
