Proof-of-Stake Blockchain Protocols with Near-Optimal Throughput

Matthias Fitzi, Peter Gaži, Aggelos Kiayias, and Alexander Russell

Abstract

One of the most significant challenges in the design of blockchain protocols is increasing their transaction-processing throughput. In this work we put forth for the first time a formal execution model that enables to express transaction throughput while supporting formal security arguments regarding persistence and liveness. We then present a protocol in the proof-of-stake setting achieving near-optimal throughput under adaptive active corruption of any minority of the stake.
