Shamir secret sharing scheme
This presentation explains how the Shamir secret sharing scheme works.
This scheme allows uses to break a secret into multiple pieces and enforce a minumum number of secrets out of all to be presented in order to construct the original secret reliably.
High school math and some going along with intuition.
This will explain a new concept called Lagrange basis polynomial, All intuition will be given from scratch so no pre-reading required for this.
