Abstract
Thanks to the emergence of blockchain and public ledger technology, we are nowadays moving fast toward a brand new world of decentralized and secure organizations. Given the blockchain at hand, a large number of individuals can coordinate, interact and trade directly, thus governing themselves without the help of centralized platforms.
This talk will begin with presenting how individual people can interact through the blockchain to crowdsource human intelligence securely and efficiently. The design is secure and robust, as it not only gets rid of the vulnerable reliance on centralized third-parties, but also mitigates the inherent transparency issues of the blockchain to attain data privacy as well as user anonymity. In addition, the design is efficient and practical, and even financially cheaper than the existing centralized systems such as Amazon’s Mechanical Turk.
Finally, I will briefly introduce our recent breakthrough towards robust and high-performing public ledger. At the core of the result, we solve a long-term open problem, that is how to realize a multi-valued validated asynchronous Byzantine agreement with only linear communication complexity, which has been the major issue slowing down the real-world deployment of asynchronous Byzantine fault-tolerant protocols since 2001.
