In the latest Cardano Whiteboard 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 “Kaleidoscope, eprint, IACR”, 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).
