A Scalable Proof-of-Stake Blockchain in the Open Setting
Lei Fan, Jonathan Katz, and Hong-Sheng Zhou
Stanford Blockchain Conference (BPASE) 2019
Bitcoin and blockchain technologies have proven to be a phenomenal success. The underlying techniques hold huge promise to change the future of financial transactions, and eventually the way people and companies compute, collaborate, and interact. At the same time, the current Bitcoin-like proof-of-work based blockchain systems are facing many challenges. We propose a new approach to constructing energy-efficient blockchain protocols.
