Money Stack (analogous to Software stack): Ledger/Record -> Currency/Exchange -> Debt/Finance -> Property/Ownership. In the decentralized world, it's: Blockchain -> (either the same blockchain, or layer 2) -> DeFi -> NFTs. I feel like it was an interesting intro, but would have loved to hear the concept further fleshed out. What are the implications of this decentralized money stack? How can it operate differently? Clearly it will be faster, at lower cost, with greater security, and provide access on a global level (plus in areas without a very stable "money stack"). Interesting to see how it develops.
