What is FRAX versus caroc?

Could you elaborate on the key differences between FRAX and Caroc in the realm of cryptocurrencies and finance? FRAX, as I understand, is a fractional-algorithmic stablecoin designed to maintain a peg to the US dollar. However, I'm not entirely familiar with Caroc and how it compares. Does Caroc have a similar goal of maintaining stability? Are there any notable differences in their underlying technology or mechanisms? Moreover, how do investors and market participants perceive these two projects, and what are the potential risks and rewards associated with each? I'd appreciate a concise yet comprehensive overview of the key distinctions between FRAX and Caroc.
