We explore combining batch order-fair atomic broadcast (of-ABC) and frequent
batch auction (FBA) as a defense against general order manipulations in
blockchain-based decentralized exchanges (DEX). To justify FBA, we compare the
welfare loss of decentralized exchanges under two market designs: continuous
limit order book (CLOB), where transactions are processed sequentially, and
FBA, where transactions are arranged into batches and a uniform price double
auction decides execution order. We model three types of players, common
investors, privately informed traders, and arbitrageurs …
