SecAppDev 2022 Lecture Details
Cryptocurrencies and blockchains
Monday June 13, 14:00 - 15:30
This lecture offers a perspective on the building blocks and concepts of blockchain technologies. It will go beyond the hype and look at the underlying technologies and their strengths and weaknesses.
This lecture offers a perspective on the building blocks and concepts of blockchain technologies. We will explain the background of distributed consensus, timestamping and secure logging. Next, we will discuss the fast rise of cryptocurrencies based on proof of work, with Bitcoin as most prominent example. In about a decade, a white paper of nine pages has resulted in massive capital investments, a global ecosystem with a huge market capitalization. Next, we explain how several variants attempt to improve the complex tradeoffs between public verifiability, robustness, privacy and performance.
Cryptocurrencies are here to stay. Blockchain can bring innovation through novel ecosystems and cool cryptography.
Anyone who wants to understand the technologies and facts that lie behind the blockchain hype.
