Digital innovation is significantly reshaping the financial services landscape, pioneering new avenues for sustainable access, distribution, and management of financial resources. A myriad of real-world applications, such as enabling digital supply chain finance across agricultural and fashion value chains, and leveraging digital currencies to fuel smart meters in schools in developing nations, are continually emerging. Moreover, the advent of digital investment marketplaces, crowdfunding platforms, token-based financing, new payment infrastructures, digital wallets for waste management, and blockchain-based autonomous decentralized organizations, among others, underline the expansive and inclusive capabilities of digital finance. The potential of digital innovation extends far beyond our current imaginings. In this vein, this book seeks to present visionary, yet practical, perspectives that employ innovative technologies to address overarching sustainability challenges.
