Blockchain Security for the Internet of Things: Challenges

TL;DR: A review paper mapping blockchain-and-IoT security problems to proposed defenses and open research questions.

About This Document

Mohammed Al-Shabi and Abdulrahman Al-Qarafi survey how decentralized ledgers are proposed for Internet of Things deployments and where those systems remain exposed. They discuss architecture, attacks, privacy, access, authentication, resource constraints, and the limits of existing protection methods. The paper organizes prior work rather than presenting a Bitcoin implementation or one fully validated security protocol.

Why Bitcoin People May Care

This is not a Bitcoin paper. It addresses application blockchains connected to constrained physical devices, where endpoints, gateways, identity systems, and data feeds can fail even if ledger records are hard to alter. Bitcoin readers may care because the paper separates ledger integrity from whole-system security. Its survey reflects literature available to the authors in 2022.
