## Abstract
This supporting document introduces a BLS based M-of-N threshold scheme. First, a simple M-of-N threshold scheme based on [Shamir’s Secret Sharing](https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing) is introduced. As the simple scheme requires a trusted dealer of key shares, it is unsuitable in a decentralized network. A more advanced, trustless and decentralized scheme is then introduced which removes the need for a single trusted dealer. Finally, a distributed key generation (DKG) protocol is introduced which leverages all this.
