In this video, we explain what "secret-sharing" is in a simple, approachable way. We also show how you can add up secret-shared numbers.
Key learnings
1. If you only have 2 out of 3 secret-shares, you learn nothing about the secret number
2. With multiparty computation (MPC) we can add up secret-numbers to find the total, without learning what they are.
3. Actually, you can compute any function on secret-inputs, learning nothing but the answer.
