We discuss the importance of AMMs (Automated Market Makers) and DEX (Decentralised Exchanges) to crypto, especially the role of Balancer Smart Pools to allow for price discovery and the bootstrapping of liquidity for new token projects. We discuss the unstoppable nature of DeFi, how to design or at least accommodate for its attack vectors, flash loans as a feature, and how the world of DEXs will interact with CEXs (Centralised Exchanges) long-term.
