This chapter integrates institutional, agency, and stakeholder theories to explain blockchain’s impact on governance. The model illustrates how blockchain technology influences governance by addressing institutional pressures, mitigating agency conflicts, and enhancing stakeholder participation through blockchain. Institutional theory explains how blockchain challenges traditional regulatory structures and undergoes institutionalization as it gains legitimacy. Agency theory highlights blockchain’s role in reducing information asymmetry and agency costs through smart contracts and real-time accountability mechanisms. Stakeholder theory emphasizes how blockchain fosters trust and participation by enabling secure and verifiable data sharing among diverse actors. The model positions blockchain as a catalyst for balancing competing stakeholder interests by providing immutable, transparent, and decentralized governance structures. However, challenges such as regulatory adaptation, governance inefficiencies in Decentralized Autonomous Organizations (DAOs), and power imbalances remain. Future research should empirically test this model to refine blockchain’s corporate and institutional governance role.
