Today’s motion is “Algo and fraction stablecoins are flawed.”

A good stablecoin can sustainably hold its peg, and recover quickly from a premium or discount. This is a basic requirement for stablecoins.

An obvious design is the bank coin model, where coins are backed 1-to-1 by fiat. But this creates a single point of failure and incurs compliance overhead.

Hence MakerDAO, which made a smart contract driven stablecoin, and is de-coupled from the banking system. But it requires over-collateralization.

So new designs popped up and tried to make the next capital-efficient stablecoin to allow under-collateralization, with innovative collateral adjustment mechanisms. We call these algorithmic and fractional stablecoins.

Historically, most of these coins failed to hold their pegs. Is there a fundamental problem? Or can these challenges be overcome?

The two debaters today include the founder of an algo/fractional stablecoin that has been holding its peg relatively well since launch, that is about half a year, as well as a well-known critic of various stablecoins.
