Blockchain technology disruptions: Exploring accounting and auditing academics and practitioners' perception

Accounting &Finance, EarlyView.
Abstract This study explores the practical impact of blockchain technology (BCT), which contrasts strongly with literature that has predominantly hypothesised BCT's potential to disrupt accounting practice. We interviewed 44 practitioners and academics with knowledge of BCT across 13 countries and industries.
