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.

nUSD is a stablecoin that is pegged to the UD Dollar. It was created by Havven, a decentralized payment network. nUSD has a dual token mechanism that provides stability. In order to generate nUSD, users must acquire Havven Coin (HAV) and lock it in a smart contract. 80% of their HAV holdings remain in collateral, and 20% of its value is generated in the form of newly minted nUSD. This collateral staking mechanism includes an incentive mechanism that rewards users with a portion of the transaction fees that are collected when nUSD transactions occur on the network. nUSD is currently an Ethereum-based token, but will soon be transferred to EOS.
