Gold Bits Coin is developing a digital currency that is backed by gold. They hope to create a digital asset with less price volatility that can be used as a medium of exchange. GBC is built on Ethereum. Their marketing materials are unclear about how much gold they have in reserve to back each Etherreum-based token.

BitBay is developing a decentralized marketplace based on a non-colateralized stablecoin. Unlike other stabelcoins, BitBay is stabilized with a dynamic peg that is meant to reduce volatility without anchoring the price to another asset. The network has a Proof-of-Stake (PoS) consensus mechanism.

The Multi-Collateral DAI stablecoin uses multiple types of collateral to back its value and an interest rate mechanism to stabilize its price. It is designed to be a digital currency with a stable value. MakerDAO is the decentralized autonomous organization that manages DAI and works to combat its price volatility. Multi-Collateral DAI was launched in November, 2019 and is meant to be a successor to the Single-Collateral DAI, that will eventually be phased out. The new stablecoin will enable new features to the Maker Protocol, such as the the Dai Savings Rate (DSR), as well as additional types of asset collateral.
