Enig: Player Replaceable Finality Layers with Optimal Validity
Simon Holmgaard Kamp, Jesper Buus Nielsen, Søren Eller Thomsen, and Daniel Tschudi
Abstract
We present two new provably secure finality layers for Nakamoto style blockchains. One is for partially synchronous networks and the other is for networks with periods of synchrony. Both protocols are player replaceable and therefore enjoy protection against denial of service attacks when run with a proof-of-stake lottery to elect the parties. The finality layers are proven secure to run on top of any Nakamoto style blockchain which has a property called \emph{finality friendliness}. Both finality layers improve on all existing provably secure finality layers in terms of communication complexity or security.
