After driving down collateralization rates, the second priority for DeFi is greater diversity of synthetic assets. Look at MakerDAO: MakerDAO produces dai, a synthetic dollar-pegged stablecoin, with no actual dollars being held anywhere in the system. All requires is an ETH/USD price feed. If we just swap out that price feed for ETH/gold instead, suddenly we can produce a synthetic gold-pegged token through the exact same mechanics. Maker and UMA are two protocols that are pursuing this, and I expect we’ll soon see a wide array of synthetic financial assets. In the future, anyone with a mobile phone will be able to buy whatever financial asset they want from anywhere in the world, all mediated by crypto.
