The chapter discusses the challenges of applying the concept of trust in the context of online interactions, and proceeds as follows: After an introductory section that combines methodological considerations with the presentation of the concept of practical trust, a second section defends the thesis that a form of trust, systemic trust, distinct from trust as a bet, is a major issue in online interactions;  systemic trust is closely linked to epistemic trust. The final section shows how this analysis may shed new light on barriers to online trust and some practical as well as theoretical problems.
