IEEE International Workshop on Lightweight Blockchain for Edge Intelligence and Security

The 1st International Workshop on Lightweight Blockchain for Edge Intelligence and Security (LightChain 2019) will be held in conjunction with 2019 IEEE International Conference on Blockchain ( in Atlanta-USA from 14th Jul to 17th Jul 2019.

Objectives and Scope:

We are witnessing the proliferation of blockchain and smart contract technologies in several areas, from cryptocurrency to cloud computing, spanning interconnected networks to smart cities. They are leading to innovative solutions that reshape our lifestyles. However, there are several challenges in integrating blockchain within the Internet of Things (IoT) mainly due to the constrained computing, networking and storage resources. To realize a practical Blockchain platform on resource restrained IoT devices, lightweight design and implementation are mandatory.

LightChain 2019 will bring researchers and experts together to present and discuss the latest developments and technical solutions concerning various aspects towards lightweight blockchain technology in the context of IoT and Edge Computing. LightChain 2019 seeks original unpublished papers focusing on theoretical analysis, emerging applications, novel system architecture construction and design, experimental studies, and social impacts of lightweight blockchain. Both review/survey papers and technical papers are encouraged. LightChain 2019 also welcomes short papers that summarize speculative breakthroughs, work-in-progress, industry featured projects, open problems, new application challenges, visionary ideas, and preliminary studies.

Submission Guidelines:

Original papers from the above mentioned and related topics will be considered. Please submit regular full papers (8 pages) and short papers (4 pages) including all figures, tables, and references. Authors are requested to follow the standard IEEE double column format with Font 10 ( ). Papers should be submitted electronically in pdf format through the EDAS website together with a short abstract (approximately 150 words). Submitted papers must not have appeared in or be under review/consideration for another workshop, conference or a journal during the review process. Each submission will be reviewed by at least three reviewers.

All papers are submitted electronically at and select track-LightChain Workshop.


The topics include but are not limited to:

– Lightweight blockchain architecture
– Lightweight but robust Proof-of-Work (PoW), Proof-of-Stake (PoS) schemes
– Lightweight consensus protocols and algorithms
– Lightweight cryptography for blockchain networks
– Blockchain based lightweight algorithms and protocols for IoT
– Blockchain based security and privacy solutions for IoT
– Blockchain enabled novel applications and services in IoT
