Low-latency, Scalable, DeFi with Zef (2201.05073v1)

Abstract: Zef was recently proposed to extend the low-latency, Byzantine-Fault Tolerant (BFT) payment protocol FastPay with anonymous coins. This report explores further extensions of FastPay and Lef beyond payments. We start by off-chain assets (e.g. NFTs). We introduce the idea of on-demand BFT consensus instances throught the example of atomic swaps between account owners.
