Blockchain for IoT: A Critical Review of the State-of-the-Art, Challenges, and Future Prospects
Open accessAbstract
This study delineates the convergence of blockchain technology with the Internet of Things (IoT), offering a critical analysis of the current state-of-the-art, prevailing challenges, and potential future directions. Initially, a comprehensive overview of the existing literature is provided, highlighting the progressive integration of blockchain with IoT networks. Subsequently, a meticulous evaluation of the present challenges, including security concerns and scalability issues, is conducted. Furthermore, this research explores the promising prospects of blockchain-enabled IoT systems, emphasizing innovations in data security, privacy, and decentralized control. Through a systematic approach, this investigation not only underscores the significant advancements in the field but also proposes potential strategies to overcome identified hurdles. The findings of this study aspire to pave the way for the development of more secure, scalable, and efficient blockchain-based IoT networks, fostering a new era of technological synergy.

Blockchain's tamper-proof storage and auditability mitigate traditional data security concerns in resource-constrained IoT devices.
“Traditional concerns surrounding data security in resource-constrained IoT devices are mitigated by blockchain’s tamper-proof storage and auditability, as highlighted by [14].”
From IoT and Blockchain for Support for Smart Contracts Through TpM (2025) · cites this paper as [14]
The “Enhancing Data Security and Privacy” section says blockchain can enable secure, transparent IoT data management and mitigate risks of breaches and unauthorized access. The “Background” section describes immutable records. Neither section establishes auditability or shows that these benefits specifically mitigate security concerns in resource-constrained IoT devices; the paper frames the benefits as promising rather than demonstrated.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
