The 9th IEEE International Conference on Blockchain 2026
(Blockchain-2026)

Exeter, England, UK, 28-30 October 2026

Sponsored by
IEEE, IEEE Computer Society, and IEEE Technical Committee of Scalable Computing (TCSC)

INTRODUCTION

The goal of this conference is to promote community-wide discussion for identifying advanced applications, technologies and theories for blockchain. We seek submissions of papers that invent novel techniques, investigate new applications, introduce advanced methodologies, propose promising research directions and discuss approaches for unsolved issues.

As a promising technique to achieve decentralized consensus, blockchain has been successfully applied into digital currency, e.g., bitcoin, for serving as a public ledger for transactions. Its secure design for supporting a distributed computing system with high fault tolerance is attracting wide attention all over the world. Blockchain has a great potential to create new foundations for our socio-economic systems by efficiently establishing trust among people and machines, reducing cost, and increasing utilization of resources. On one hand, blockchain will play an important role for secure decentralization in such emerging fields as Internet of Things, Cyber Physical Systems, edge computing, social networking, crowdsourcing and next generation wireless communications, and even more other fields. On the other hand, its advance should be further evolved in terms of scalability, security, privacy, efficiency, flexibility, availability, real decentralization and high dependability.

We welcome high-quality papers that describe original and unpublished research advancing the state of the art in ubiquitous intelligence and computing.

PAPER SUBMISSION GUIDELINE

All papers need to be submitted electronically through the conference submission website (https://hpcn.exeter.ac.uk/blockchain) with PDF format. Submitted papers must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Papers must be clearly presented in English, must not exceed 8 pages in IEEE Computer Society proceedings format (or up to 10 pages with a page over length charge if accepted), including tables, figures, references, and appendices. Papers will be selected based on their originality, significance, relevance, and clarity of presentation, assessed by at least three reviewers. All submitted papers will be judged through double-blind reviews, where the identities of the authors are withheld from the reviewers. As an author, you are required to preserve the anonymity of your submission while at the same time allowing the reader to fully grasp the context of related past work, including your own. Papers that do not conform to our double-blind submission policies will be rejected without review.

Papers accepted by IEEE Blockchain 2026 conference will be published by the IEEE Computer Society Press. At least one author of each accepted paper is required to register and present their work at the conference; otherwise, the paper will not be included in the proceedings. All accepted papers will be submitted to IEEE Xplore and EI. Distinguished papers presented at the conference, after further revision, will be invited for submission to a special issue.
