Round 1
Reviewer 1 Report
title seems so confusing
how a blockchain work can be written without the citation of
https://bitcoin.org/bitcoin.pdf
literature review for privacy preservation is not sufficient
information in section 4 and 5 are not properly/ clearly explained
Author Response
- Response to comment: (Title seems so confusing.)
Response: We have revised the title. The main idea of the topic is to resist data availability attacks while ensuring the privacy of blockchain data.
- Response to comment: (How a blockchain work can be written without the citation of https://bitcoin.org/bitcoin.pdf )
Response: We have cited this paper in the introduction to the block chain in the first section.
- Response to comment: (Literature review for privacy preservation is not sufficient.)
Response: We have supplemented the papers related to privacy protection, adding a reference to the introduction and related work respectively.
- Response to comment: (Information in section 4 and 5 are not properly/ clearly explained.)
Response: We made a corresponding explanation at the beginning of the fourth section. The following is our further reply to your suggestion.
The fourth section is the definition of the technology used in this paper, and the zero knowledge accumulator is based on bilinear mapping. The fifth section is the technical proof of the security of zero-knowledge accumulator used in privacy protection scheme and data availability scheme .
In the fourth section, bilinear mapping, zero-knowledge accumulator and local repair code are described in detail in reference 33, 8 and 5, respectively. The security analysis of section 5 is analyzed and proved on the basis of the relevant technologies of section 4.
Reviewer 2 Report
The manuscript focuses on presenting what technologies they're using, without defining what the problem (they're trying to address) is. There is no definition or clear explanation of the "scalable availability problem " , despite repeated claims of addressing the problem.
