QM wallet Chain: Blockchain Traceability using Working Vacation Queueing Model in Mobile Wallet

Smart and cashless payments through mobile wallets are the recent implementation of digital payment alternatives in developing countries to achieve competitive advantage. Blockchain is an egressing digitally managed technology (BT) which allows ubiquitous monetary transactions with the untrusted entities. In blockchain it is impossible to change records without notifying all participants and validating signatures. Hence it overcomes the security challenges that exist in the mobile wallet. In this paper, we develop a single server bulk service queueing model with working vacation which evaluates in detail the characteristics of a mobile wallet system and measures the various performances of the blockchain based mobile wallet system.
