    A Peer-to-peer Purchase and Rental Smart Contract-based Application (PuRSCA)
    (it - Information Technology: Vol. 60, No. 5-6, 2018) Niya, Sina Rafati; Schüpfer, Florian; Bocek, Thomas; Stiller, Burkhard
    This work introduces the design and implementation of an Android-based Peer-to-peer Purchase and Rental Application termed PuRSCA, which leverages Smart Contracts (SC) and the Ethereum public blockchain (BC). As a Device-to-device (D2D) communication protocol, WiFi-Direct is chosen to enable the P2P data transmission between two parties. This work results in a cost-efficient, secure, SC-based, P2P, and Decentralized application (Dapp). Evaluations on performance of this Dapp is specified in terms of its D2D deployment, transaction costs, scalability, security, and privacy.
