Companies increasingly outsource services with the intention to disseminate risks and workload (problem)with other organizations. Reasons for that may be the lack of internal expertise, reduced execution costs, andnetwork effects such as focus on the core business. Crowdsourcing is a way of disseminate the workload,utilizing external expertise and solving problems of a project with other, partly unknown, networkparticipants. The goal of crowdsourcing is to separate responsibility and to balance the workload ofemployees (peer) or to make use of suitable external workforces coordinated by network mechanisms(platform). Crowdsourcing appears in an ambivalent way and needs regulating and participatory structuresof employment. Due to the fact that a failure of a single entity may lead to the failure of the whole project,the mutually unknown participants have to rely on each other’s quality (performance). Cooperations areprone to information asymmetry and its corresponding uncertainty in terms of the partners’ behaviour whichleads to the question of trust between the cooperating partners (principal and peer). This paper addresses theentities of a crowdsourcing system under the scope of the principal agent theory and its underlyingbehavioural assumptions. Five essential elements will be derived: principal, peer, problem, platform andperformance (5 Ps). Based on this, the potentials of the blockchain technology will be explored by reflectingits functionalities to the derived elements and its contributions to ensure trust despite of informationasymmetry in crowdsourcing platforms.
