How does TUSD work?

Could you elaborate on the workings of TUSD? I'm particularly interested in understanding its underlying mechanisms, such as how it maintains its peg to the US dollar and what role does it play in the crypto economy. Additionally, I'd like to know about its use cases and how it differs from other stablecoins. Is there a specific technology or algorithm that powers TUSD? Also, how does it ensure liquidity and security for its users? I'm eager to learn more about this fascinating topic.
