Reviewer 2 Report

The integration represents a significant advancement in the development of secure and scalable IoT blockchain networks, contributing to the greater scholarly conversation on this subject. 

Since the results of the publication are not very clear, maybe it is possible to answer a few questions. The work is supplemented with answers:

• How does the blockchain-based architecture proposed in the paper enhance data security and privacy, specifically in IoT environments, compared to traditional security methods?

• How can the proposed architecture's resource consumption be optimized to handle the increased CPU and RAM usage more efficiently?

• What are potential comparative benchmarks or systems against which the proposed architecture's performance can be evaluated for a more comprehensive analysis?

• What additional features or improvements could be incorporated into the architecture to enhance its scalability and efficiency, especially for large-scale IoT deployments?

The obtained result of a peak transaction throughput of 798.3 transactions per second (TPS) in the blockchain-based IoT architecture can be compared to other blockchain platforms or IoT security solutions. For instance, it could be benchmarked against popular blockchain networks like Bitcoin or Ethereum, which have lower transaction throughputs due to their design and consensus mechanisms. Additionally, comparing this result with traditional IoT security methods that don't use blockchain technology would provide insights into the efficiency and scalability improvements offered by the blockchain approach in IoT environments.

The work is relevant, but there is no clear conclusion, and there is a lack of technological comparison. Authors could answer questions and add to the publication. 

p.s. should not use GPT to come up with a title for a scientific publication

Reviewer 2 Report

Taking into account all your observations, the paper's blockchain-based architecture for IoT offers enhanced data security and privacy compared to traditional methods, thanks to its decentralized nature. Addressing the architecture's higher CPU and RAM demands requires optimized resource management strategies. Incorporating additional features for scalability and efficiency would further strengthen the architecture, making it more suitable for extensive IoT deployments.

The research done for it is definitely valuable. The essential comments have been taken into account, and the document has been updated. Although "discussion" has changed, it is a somewhat weak part. Overall, the work is good and suitable for publication.
