Design and Implementation Considerations of POA Network Architecture in the Ethereum Blockchain

Abstract

The upcoming technology in creating the distributed applications for different use cases in real world applications are Blockchain technologies. The application may be private or public depending upon the use cases. Most of the applications are built by using the Ethereum platform in blockchain for use of security purpose. The nodes in the distributed network shares all the data to the other nodes without any modification of the data in the blockchain technology. The transactions done by the nodes were trusted through the digital signatures. Here, no central control or the central system will be there to keep track of other nodes data. In this paper, we built the POA network by using the Ethereum blockchain platform. The network is called the Proof of Authority and its main purpose is to deploy the contracts especially with authority in the Ethereum blockchain platform. We also explained about the ERC20 tokens, the working process of using the POA network and the codes for connecting with the web page.
