“Finance is not merely about making money. It’s about achieving our deep goals and protecting the fruits of our labor. It’s about stewardship and, therefore, about achieving the good society.” — Robert J. Shiller

  2. Transparency: Unlike the ‘black box’ operations of many financial institutions, DeFi runs predominantly on public blockchains. This means that every transaction is transparent, and if you’re tech-savvy enough, you can audit the protocols or track transactions on your own.

  5. Programmability: This is more on the technical side, but a crucial facet of DeFi. It means that…
