A Cost-efficient Protocol for Open Blockchains
Chunlei Li, Chunming Rong, Martin Gilje Jaatun · 2019
Current proof-of-work blockchains are not sustainable in terms of energy needed to run them. In this paper we propose a new scheme that avoids wasted proof-of-work by a dynamic probabilistic method, where the consensus algorithm can be adjusted according to the parties' required assurance levels.
