Abstract:

Bitcoin is a crypto-currency which differs in several ways from the traditional use of money. It does not require an individual name but digital wallet IDs, which make it more private. Bitcoin technology currently lacks protection with respect to monetary transfers, and its structure is not endorsed by the governments. Understanding the concept of trust is fundamental to Bitcoin technology. E-trust is defined as trust of a person or user in digital environment. This paper offers a review of relevant work on trust in HCI, and critically examines its value in understanding the issues of trust in Bitcoin technologies. Several limitations of the current theories and models of trust are identified, and a novel research framework is proposed to address the specific trust challenges raised by the Bitcoin technology.
