Blockchain systems and ethical sourcing in the mineral and metal industry: a multiple case study

Abstract

Purpose The purpose of this paper is to examine blockchain's roles in promoting ethical sourcing in the mineral and metal industry. Design/methodology/approach It analyzes multiple case studies of blockchain projects in the mineral and metal industry. Findings It gives detailed descriptions of how blockchain-based supply chain networks' higher density of information flow and high degree of authenticity of information can increase supply chain participants' compliance with sustainability standards. It gives special consideration to blockchain systems' roles in overcoming the deficits in the second party and the third-party trust. It also demonstrates how blockchain-based supply chain networks include outside actors and configure the supply chain networks in a way that enhances the empowerment of marginalized groups. Practical implications It suggests various mechanisms by which blockchain-based supply chain networks can give a voice to marginalized groups. Originality/value It demonstrates how blockchain is likely to force mineral and metal supply chains to become more traceable and transparent.
