Reviewer 2 Report

Dear Authors, 

I read with interest your research paper. Below are some suggestions to strengthen it. 

Title, abstract, and keywords

Interesting and relevant. 

Introduction

This section is almost well-written. However, something is missing. 

For instance, I would encourage adding more elements to the background side of this section. Why is blockchain so revolutionized? Why is the researcher considering it? What are the market data of blockchain? 

Here, you may consider some elements:

https://doi.org/10.1108/AAAJ-10-2020-4987

10.1109/TEMSCON.2017.7998367

Additionally, several paragraphs are without references. See, for instance, page 2, lines 42-59.

"The blockchain transaction retrieval problem is because blockchain nodes no longer have the complete blockchain ledger data when storing the blockchain ledger in third-party storage networks" who stated this?

Please, rename it in Literature Review.

Experiments' Results 

Interesting and well-developed. 

Conclusions

In this section, I can suggest strengthening it much more. For instance, you should restart from the background of your research paper, why you study this, and then report your main results. After this phase, it's essential to report your paper's theoretical and practical implications. Notably, within the practical implication side, you should declare which stakeholders may be helpful to in your paper and why? How can they apply it?

References

Several sections are without references. Please, add them. 

All the best
