Decentralising Trust and Information Symmetry: Seeking Retrospective Common Knowledge in Blockchain Enabled Supply Chains

Abstract

This thesis explores how blockchain technology improves trust and efficiency in supply chains, particularly for small and medium enterprises. By combining distributed ledger technology with financial principles, the research developed practical frameworks including a live financial instrument backed by real assets. A key theoretical contribution is "Retrospective Common Knowledge," explaining how blockchain creates shared understanding among participants after events occur. The work addresses data accuracy challenges through multi-party verification and demonstrates practical applications in the beef supply chain, showing how blockchain reduces miscommunication and enables better coordination in global trade.
