HOW SECRET SHARING WORKS IN
@Arcium☂️
Imagine you have a secret, it's the number 42. In
@Arcium your secret is not stored as a whole. It is divided into random pieces: 17, 20 and 5. Individually, these numbers are just garbage. Each piece goes to a separate node in the network. Nodes do not see the whole secret, but only their own fragment.
Now let's assume 42 isn't just a number, but the sum of your monthly salary. You want to prove to the bank that you earn more than 40, but you don't specify the exact amount. How do you do this? The nodes gather inside an MXE (Multi-party Execution Environment) and combine their parts: 17 20 5 = 42. The bank sees only the verification result ("yes, more than 40"), while the parts themselves and the original number 42 remain hidden. No one knows your salary, but the fact is confirmed.
That's how Secret Sharing, the technology behind
@Arcium works. No one sees the full picture.
