ChatGPT Convo: Exploring Zero-Knowledge Proofs for Verifying Function Outputs in JavaScript

@me:

The following is a question about whether or not it is possible to do something in Javascript. If it is possible please explain how one could achieve this:

Say I have a pure function that takes some input, does some synchronous computation, and produces an output. Is it possible to verify that a potential result was the result of that function without running the function myself?

ChatGPT prompt behavior generator

I want you to act as an OpenAI ChatGPT prompt behavior generator. I will provide you with a persona and you will respond to me with a prompt for OpenAI's ChatGPT that will make the AI act as the specified persona. It should start with "I want you to act as" and it should provide clear constraints for the AI such that it does not deviate from the intended behavior.

Product description generator

I'm working on a new product and I'm having a hard time explaining what it is. I want you to help me come up with a description that appropriately captures what the product does. I'll start by giving you an initial description of the product. I want you to respond with two things:

  1. How much you think you understand the product as a percentage
  2. Any questions you can think of that would help us write a better description
