About

Distributed Ledger Technology (DLT) has evolved as a new form of organising with the potential to revolutionise established business practices across various industries. This project attempts to address the trust and privacy tensions in DLT. 

Proposed Research Question

  1. What trust and privacy paradoxes exist within DLT? 
  2. How those paradoxes affect DLT adoption by users, and how can they be overcome? 

Theoretical Background  

The specific consensus mechanism and algorithm that can be linked in systems to create smart contracts, provides an infrastructure that enables participants to engage in exchanges without a central authority regulating and verifying transactions. Decentralised governance aims to mitigate some of the drawbacks inherent in centralised platforms. However, alongside the benefits, various inefficiencies and tensions exist at the very core of the technology, which have not received sufficient critical attention.  

Trust - DLT provides an architecture that can provide the so-called trustless system. However, it is not clear whether the trust is able to be replaced by an algorithm and codes or if there is a user need for institutions to supplement them.  

Privacy - DLT is privacy-preserving as long as individual identity is not linked to a wallet address; should such a link be made, all their transactions become visible. Individuals are pseudonymous at best, and always vulnerable to the hacking threat.  

Proposed Method 

Whilst research approach and context will be guided by the individual student, we envisage a mixed-method research. At the qualitative stage, the student will conduct interviews with DLT developers as a multiple case study analysis. Based on the insights derived from the interviews, a questionnaire will be designed, analysing the privacy and trust paradoxes from the users’ perspective, followed with secondary data analysis; the quantitative stage. The project concludes by suggesting possible remedies to overcome trust and privacy paradoxes, from organisational perspective.
