The current DeFi movement is just the beginning of this wave of killer financial apps. As Ethereum powers this ecosystem it will appreciate dramatically as users scramble for the Ethereum “‘gas” to play at the table.
So here it is, the next Ethereum killer app: DeFi. DeFi stands for decentralized finance. What is that? It’s a range of semi-familiar financial products reskinned for the crypto age. Imagine you could anonymously deposit some collateral with a bank and then borrow cash on the security of that collateral, then withdraw the borrowed money so you could spend it, without them knowing who you are. Of course you can’t do that at Wells Fargo WFC +0.2% or Barclays Bank, but with DeFi you can get that done in a few minutes flat.
