Host Tom Shaughnessy of Delphi Digital is joined by Alex Wearn, the co-founder and CEO of IDEX, a decentralized exchange built on Ethereum, to discuss the next version of the exchange and using optimized optimistic rollups to scale the exchange.

Topics Discussed

IDEX 2.0 - UI improvements (faster and more performant) and a more efficient settlement process with rollups instead of settling each transaction one by one (IDEX users paid $5M in gas fees in 2018). IDEX differs from competitors (Uniswap etc) by having a high performant order book. An on-chain order book is great for integrations, but hard to use when replicating complex trading strategies. In competing with 0x, IDEX disagrees that trying to have a high performant order book may be too difficult if its decentralized. How the different types of rollups work to drive scale for Ethereum, and the differences from normal rollups to IDEX's version called optimized optimistic rollups. Optimized Optimistic rollups can drive much higher throughput vs using traditional rollups. How IDEX grew to been the most successful DEX and dapp to date, with over 300k users executing five million trades worth over $2 billion. The use of optimized optimistic rollups beyond IDEX, such as in gaming. Alex's thoughts on the battle between centralized exchanges (Coinbase, Binance, Bitmex, Delta) vs Decentralized exchanges (IDEX, Uniswap, 0x, etc).
