A blockchain-based data-driven trustworthy approval process system

Abstract

Approval processes are intra-organizational business processes designed to sanction the execution of specific administrative tasks. Purchasing essential stationery products, filing bills for acquired items, approving attendance at conferences, processing insurance claims, approving loans, and similar tasks are examples for which employees require approvals from multiple authorities within an organization. Common concerns mentioned by both the approving authority and the proposal submitter are the genuineness of the proposer and the time required for approving the proposal. This paper presents a novel Blockchain-based Approval Process System (BAPS) to establish mutual trust between the submitter and the approving authorities. The proposed system’s design, implementation, and evaluation are included in this paper. The suggested approach can shorten the time needed to obtain the permissions and increase transparency between the users and the authority. In addition, it eliminates issues such as the misplacement of papers. It stores the information in a secure and tamper-proof platform which is some of the most significant drawbacks of traditional paper-based systems.
