Blockchain and distributed ledgers: Will the reality live up to the hype? Will distributed ledger provide a ‘reset’ button for the internet and other networks? Many of the primary privacy risks prevalent today are due to an increasing centralization of information. A decentralized network is potentially more secure but not without its vulnerabilities. During this session, a panel of experts will illuminate how distributed ledgers work, discuss their potential and explore how the world of finance and other application areas could be reshaped. Cryptocurrencies and their escalating, volatile values have successfully captivated the public. However, the rise to fame has not brought a thorough understanding of the underlying technology along with it and distributed ledgers remain largely misunderstood. A better comprehension of the technology is increasingly vital due to its potential ramifications in finance and regarding privacy. Distributed ledgers could conceivably reshape finance through cryptocurrencies and smart contracts, cure data protection issues with social media and re-decentralize the internet. In short, a chance to hit the ‘reset’ button. Simultaneously, the very aspects that make distributed ledgers so promising are the same that make it vulnerable. Though replicability, immutability and being append-only are enormous strengths, they are equally large burdens when used maliciously. The Hot Topic was coordinated and will be moderated by Eva Wolfangel, European Science Writer of the Year 2018, a science journalist with over 15 years of experience covering a range of scientific issues and technological developments and highlighting their significance for the public. In order to unravel the technology behind distributed ledgers and its potential implications, Wolfangel has enlisted the help of experts with backgrounds ranging from academia to industry. Through discussions and an open debate, the speakers aim to distinguish the implausible from the practical and distill how the distributed ledgers will further influence our lives.
