We asked @_seanli of @MagicNewton about the concept of a trusted agent and untrusted agent.
“I like to describe trusted agents through analogies”
“It’s like a self-driving vehicle where you set a destination and parameters like speed, and the car follows through to get you from point A to point B.”
“In the middle, you want a secure computer that does the task based on your parameters, and no one should be able to tamper with that”
“Everything is recorded in the verifiable part, every turn and action is recorded like in a flight black box with a notarized log where you can check if they did the correct actions afterwards.” 
“That’s the ZK proof part, and underneath we use @SuccinctLabs and @RiscZero for the infrastructure.”
