DeFi Lending and DeFi Exchanges
These other companies protocols are built on public blockchains such as Ethereum. Ethereum, and other public blockchains, are run by thousands of computers across the globe. In other words, there is not one central entity in control of the financial system- it’s thousands. This is the entire purpose of them.
Platforms are built to be managed by a community of users, and not centrally controlled. Users can become owners of their own financial destiny without a centralized party unilaterally taking control of funds. Check disclaimer on my profile.
