They call it DeFi

Informally we can still say sandbox.

DeFi projects like Maker are actually different because the root of trust on top of which they are designed is an open, decentralized and censorship resistant blockchain platform. Here is the actual list of every loan Maker has ever given out, open for anyone to see. It’s also the first bank to tell you, Joe Schmo Public, its exact leverage ratio in real-time — a privilege that even the CEO of the hottest challenger bank probably doesn’t have.
Like all DeFi projects, MakerDAO has never discriminated based on race, gender, nationality, income level or any other factor beyond financial qualification. A poor person in Vietnam borrowing a few dollars from Maker pays the same interest rate as a billionaire in America taking down a giant loan. Can your favorite FinTech offer the same?
Then there is the superfluidity of the DeFi ecosystem. Every user can move seamlessly from borrowing to saving to trading to market making to investing in synthetic assets, and from crypto exposure to dollars to gold to the S&P 500, all within a few minutes and for just pennies in fees.

Maker runs a sandbox compatible S/L, evidently.  I think they read my blog. A $150 million loan portfolio, like a small bank, but they will grow.

This has been ging on far a couple of yeas, this DeFi. Dunno how many times I have repeated the basics, someone needs to write the book.
