## AI overview

This tutorial introduces the secret sharing problem and describes a protocol in which a secret can be reconstructed from any required number of participants' pieces, while fewer pieces cannot reliably recover it. It presents the protocol in Haskell.

## Source excerpt

Here's a simple puzzle with a neat story. A rich old woman is drafting her will and wants to distribute her expansive estate equally amongst her five children. But her children are very greedy, and the woman knows that if he leaves her will unprotected her children will resort to nefarious measures to try to get more than their fair share. In one fearful scenario, she worries that the older four children will team up to bully the youngest child entirely out of his claim!
