Understanding Crypto 7: Nicholas Weaver: A Computer Scientist's Perspective on Cryptocurrencies and Blockchain

When speaking about crypto and DeFi, it is inevitable that the topic of financial security will arise, one of the main selling points for crypto proponents. Today, we put the debate to rest as we speak to Dr. Nicholas Weaver, a technologist and academic who has been following the development of cryptocurrencies since the inception of Bitcoin. He holds a BA in Astrophysics and Computer Science and a Ph.D. in Computer Science from UC Berkeley, where he is also a professor. His primary research focus has been network security, among other topics, and he has several published papers under his belt concerning cryptocurrency technologies. In our conversation, Dr. Weaver untangles the complexities of the perceptions of cryptocurrencies with the actual technology. We talk about decentralization, if cryptocurrencies are achieving it, and the underlying concept of blockchain technology, as well as whether or not blockchains are secure and what the potential benefits of cryptocurrencies are to developing countries. We then go into detail about why Dr. Weaver thinks the crypto space is not beneficial, the rising popularity of the space, and how cryptocurrencies make money, as well as why he thinks it will never work, and much more. Please tune in for a truly eye-opening, no-holds-barred episode as we learn the harsh truth about cryptocurrencies with expert, Dr. Nicholas Weaver!
