"Beginning in 2015, the MakerDAO project operated with developers around the globe working together on the first iterations of code, architecture, and documentation. In December 2017, the first MakerDAO formal white paper was published, introducing the original Dai (now Sai) Stablecoin System. The Dai Stablecoin System, today called the Maker Protocol, now accepts as collateral any Ethereum-based asset that has been approved by MKR holders, who also vote on corresponding Risk Parameters for each collateral asset. Voting is a critical component of the Maker decentralized governance process."
