# 1. A Silent Revolution

Introduction:
The digital era has ushered in a new paradigm where the flow of information, people, and money is intricately intertwined with technology. This chapter delves into the concept of the Public Digital Backbone, elucidating its significance in this interconnected world. Why to call it 'Public Digital Backbone'? Because Digital Public Infrastructure (DPI) differs from the simple provision of services via digital channels, as the crux of DPI is that it empowers others to utilize the infrastructure in their own applications. We hope the readers will have a clear understanding of what constitutes a Public Digital Backbone, its historical development, and its overarching goals in societal infrastructure.
In the annals of human progress, infrastructure has always played an indomitable role, connecting people, facilitating financial transactions, and disseminating information. While the 19th and 20th centuries heralded an era of physical infrastructure like railways and telecommunication, the 21st century has marked the onset of a digital renaissance: Digital Public Infrastructure (DPI).
At its essence, DPI is the digital foundation that allows for the construction and delivery of applications for public welfare. Envisioned as a multi-layered structure, it encompasses identity, payments, data management, and consent, further culminating in layers of health, education, agriculture, logistics, and many more. At its pinnacle, it supports a plethora of apps and solutions tailored for diverse needs.
Acting as the digital arteries of a nation, DPI mediates essential flows: 1. People: Digital ID systems, 2. Money: Real-time payment systems, 3. Information: Consent-based data sharing systems ensure users have control over their personal data, as seen in India's Account Aggregator built upon the Data Empowerment Protection Architecture (DEPA).
However, amidst its numerous merits, it's crucial that DPI remains guarded against pitfalls like monopolization, digital colonization, and authoritarian control. It is here that the techno-legal structure comes into play, blending technological tools and legal regulations to forge a robust infrastructure that aligns with democratic principles.
A key feature of DPI is its open architecture. This openness, integral to DPI’s DNA, comprises: Open Standards: Freely available protocols ensure DPI’s vast compatibility. Open Source Software: Providing transparency and allowing collective enhancement, ensuring DPI remains progressive. Open Data: Ensuring data availability for public benefit without compromising individual privacy. Open Governance: Ensuring DPI's transparent and accountable management.
While the value of openness is irrefutable, balancing it with privacy remains paramount. Innovations like data anonymization and privacy-preserving technologies ensure that while data remains accessible, individual privacy isn’t jeopardized.
How can the centralization of such vast amounts of data be prevented? The answer lies in a multifaceted approach. Decentralization distributes data across diverse locations. Encryption ensures data remains unintelligible to unauthorized entities.
DPI, with its transformative capabilities, is not just an evolution; it's a silent revolution. As India has demonstrated with Aadhaar, UPI, and Digi-Locker, this infrastructure has the potential to redefine public service delivery. By fostering innovation, ensuring inclusion, and empowering individuals, DPI isn’t just creating a digital commons; it’s democratizing the digital future.
The beauty of the DPI framework lies in its participatory nature. Its open-source character invites developers, policymakers, and even everyday citizens to contribute to its evolution. It's a collaborative ecosystem where public and private entities, civil societies, and individuals converge, each bringing unique perspectives and skills.
For businesses, DPI offers unprecedented opportunities. With a reliable and efficient infrastructure in place, entrepreneurs can innovate without reinventing the wheel. They can build upon existing DPI layers, focusing their energy on creating niche solutions tailored for specific community needs.
