Quantum Computing and Blockchain in Business

By: Arunkumar Krishnakumar

Overview of this book

Are quantum computing and Blockchain on a collision course or will they be the most important trends of this decade to disrupt industries and life as we know it? Fintech veteran and venture capitalist Arunkumar Krishnakumar cuts through the hype to bring us a first-hand look into how quantum computing and Blockchain together are redefining industries, including fintech, healthcare, and research. Through a series of interviews with domain experts, he also explores these technologies’ potential to transform national and global governance and policies – from how elections are conducted and how smart cities can be designed and optimized for the environment, to what cyberwarfare enabled by quantum cryptography might look like. In doing so, he also highlights challenges that these technologies have to overcome to go mainstream. Quantum Computing and Blockchain in Business explores the potential changes that quantum computing and Blockchain might bring about in the real world. After expanding on the key concepts and techniques, such as applied cryptography, qubits, and digital annealing, that underpin quantum computing and Blockchain, the book dives into how major industries will be impacted by these technologies. Lastly, we consider how the two technologies may come together in a complimentary way.

Decentralization

Decentralization has been the magic mantra of millions of Blockchain believers across the world as the technology has gained in popularity over the years. Thanks to the scalability trilemma that we discussed earlier in this book, decentralization often seems to be an obstacle to achieving commercial scale. Where scalability has been achieved by Blockchain, decentralization has often been traded off, making it an elusive utopian idea that we all want the world to move towards.

However, decentralization does have its advantages. Over the years, we have all gotten used to client-servers systems, where most of the data is stored on the server. The challenges with this architecture are that:

  • The server that holds most of the data is an easy target for cyber criminals. Hacking a centralized system to get hold of critical information is easy. There have been several instances where banks have been hacked and millions of clients' data was lost...
