Implementation of Blockchain and Peer-to-peer Network for Digital Document Management
Bagas Fadillah Islamay, Yudha Purwanto, Muhammad Faris Ruriawan · 2022
Digital document storage usually implemented using conventional methods, namely by using a centralized database system that allows trust issues to arise due to the possibility of manipulation or interference from irresponsible parties. Therefore, we need a secure system that can prevent things like this from happening. For that, blockchain can be a solution to this problem. By using a blockchain-based system, the digital document management process can be carried out more transparently by only using the read and write method so that stored documents can still maintain their legal value. The end of this research results in the form of a decentralized application for digital document processing. Based on the results of white box testing, it is found that the web interface and smart contracts can run 100% however, the continuity of transactions is strongly influenced by several variables such as the computational ability of Rinkeby test network and the number of transactions that are executed at the same time. Based on the results of the black box test, the average file upload speed was 40.61 KBps with the component specifications as written in this journal. Furthermore, it was found that modifying 1 bit of data in a file would make the file identified as a unique file despite the content presented has not changed.
