In this video IOHK researcher Bernardo David introduces Kaleidoscope, a cryptographic protocol for securely playing poker, a research paper accepted to Financial Cryptography 2018. Cryptographic protocols can be used to securely play poker over a network without trusting any third party. Constructing such protocols has been a research topic since the early days of modern cryptography. However, no cryptographic poker protocol has ever been adopted for real applications, mainly due to financial, security, and efficiency concerns. Kaleidoscope https://eprint.iacr.org/2017/899 âKaleidoscope, eprint, IACRâ, is the first cryptographic poker protocol to address these three issues. It is the first protocol to be proven secure according to a comprehensive security model that formally and clearly captures all the properties and guarantees commonly required from a poker protocol. Moreover, Kaleidoscope employs blockchain techniques to ensure that winners receive their rewards and that cheaters are financially penalized. Even though it is mathematically proven to achieve security while providing financial rewards and penalty enforcements, Kaleidoscope achieves very high efficiency in comparison to existing solutions (which have not been formally proven secure).

He holds a Ph.D. in Computer Science from Aarhus University obtained in 2017 under the supervision of Ivan DamgÃ¥rd and Jesper Buus Nielsen. He has also been a long-term visitor at the NTT Secure Plaftorm Laboratories working with Tatsuaki Okamoto and Masayuki Abe and at the Cryptography Group at Bar Ilan University working with Yehuda Lindell. Bernardo is interested in a broad range of topics in cryptography and information theory. His current focus is on theoretical and practical aspects of secure multiparty computation and blockchains/cryptocurrencies. https://iohk.io/team/bernardo-david/ -- See more at: https://iohk.io Get our latest news updates: https://iohk.io/blog/ Meet the team: https://iohk.io/team/ Learn about our projects: https://iohk.io/projects/cardano/ Read our papers: http://iohk.link/paper-ouroboros Visit our library: https://iohk.io/research/library/ In the press: https://iohk.io/press/ Work with us: https://iohk.io/careers/ See more on Cardano: https://iohk.io/projects/cardano/ -- The Cardano PortfolioThe Cardano HubThe source for all things Cardanohttps://www.cardanohub.org/en/home/ Cardano Blockchain Explorer An open source block explorer for the Cardano project https://cardanoexplorer.com Cardano Documentation Full technical documentation of the project https://cardanodocs.com Cardano Roadmap Development path of the Cardano project https://cardanoroadmap.com Why Cardano The philosophy behind the project https://whycardano.com Daedalus Platform Open source platform https://daedaluswallet.io The Cardano Foundation Supervisory and educational body for the Cardano Protocol https://cardanofoundation.org Cardano Foundation YouTube All the latest videos & tutorials https://www.youtube.com/channel/UCbQ9...
