A Blockchain-Based Trusted Edge Platform in Edge Computing Environment

Round 1

Reviewer 1 Report

The concept is good and relevant timely, similar to what is shown at “Sensors 2021, 21(5), 1559; https://doi.org/10.3390/s21051559” . However, the security you talk about blockchain can be performed with a simple token exchange like in OAuth 2.0 and SSH much lighter and secure as already proven. For example, the same concept which is presented about trusted and distribute data can simply be implemented with a YAML file and SSH tokens executed under open-source tool Ansible for distributed architecture, but faster and simpler compared to proposed architecture due to eliminating extra layers of microservices like dockers and Kubernetes.

Furthermore, the authors demonstrate the concept only between a pc and raspberry, the question is: where is the distributed cluster architecture?

The authors should reconsider the proposed solution and test it at the list in a distributed cluster of edge computers before publishing

Reviewer 2 Report

This work aims to integrate an edge computing framework and blockchain network to provide edge computing clients with a secure authentication mechanism. - The combination of edge and blockchain is not new, there are something new are expected for this. Also, the keyword - blockchain needs to be mentioned in the title. - In the evaluation, it is unclear how to implement the blockchain. - A comparison with similar studies need to be considered. - Writing needs to be improved under a professional editing
