As time progresses, other guarantors will place their assets on the blockchain similarly to Digix. And when other guarantors come online, Maker will be free to add those to the pool. As it stands, Digix provides Assay certificates and undergoes third party auditing. MakerDAO is off to a great start. They're doing all the right things to build a sustainable stable coin.
