cluster is individually more efficient in terms of both energy utilization and security

for IIoT systems by using different computationally suitable hash algorithms. The

higher efficiency of the proposed model compared to current solutions is proven by

experimental results.

A digital ledger which is based on distributed technology will help to address

cybersecurity and secrecy problems in the Internet of Things Architecture, but

combining these two technologies poses some difficulties. In order to preserve

a tradition of financial transactions, cryptocurrencies introduced DL technology.

The DL size in a cryptocurrency addresses hundreds of GBs, while the storage

of IoT nodes is limited. Similarly, cryptocurrencies implement costly processes of

consensus, while IoT nodes in calculation and energy are restricted. Moreover, classic

distributed ledger technology (Bitcoin) is not based on quantum. Chapter “Quantum

Aware Distributed Ledger Technology for Blockchain-Based IoT Network” aims on

a distributed ledger security based on quantum technology, specifically Distributed

Ledger for Internet of Things, for IoT architectures. One cornerstone of the chapter

is a new signature creation scheme which is named as Single Time Signature based

on time (STS), Blockchain-STS, a compact scheme. Compared with the famous

Winternitz-OTS+ system, Blockchain-STS offers a 75 percent reduction in signature

size and a 76 percent reduction in signature generation time.

Chapter “BCoT: Concluding Remarks” summarizes the findings reported in the

volume with future directions of research.

The book is intended for researchers, academicians, and practitioners working in

the field of blockchain-based IoT. This volume will serve as a readymade material for

the researchers and academicians as it covers a wide range of subject areas belonging

to several majors falling under the umbrella of blockchain-based Internet of Things

for Industry 5.0. The editors will feel rewarded if this edited volume comes to the

benefit of the end users.
