I've long felt that a price-stable cryptocurrency is vital to increased acceptance of cryptocurrency by businesses and the public at large. There are a few solutions to this problem out there, but, in my opinion, they are either too centralized (and require too much trust) or they're too complicated. I wanted something simple, distributed, and trustless, so I made Unum.<p><a href="https://unum.one" rel="nofollow">https://unum.one</a><p>Unum is implemented as an ERC20 token smart contract on the Ethereum Blockchain. If you send in $20 worth of Ether, you get 20 Unum. If you send in $100 worth of OMG, you get 100 Unum. Whatever you send in is held in reserve by the smart contract. I can't touch it, and you can exchange your Unum into any currency held in the reserve whenever you'd like. Both buying and selling Unum incurs a 0.05% fee, which I plan to use to pay for the Ether needed to maintain the USD price oracle contract that's used to maintain the dollar peg. For every $100 you send, $0.05 is held as a fee.<p>Right now Unum is deployed on the Ethereum Ropsten testnet. I'd love feedback on the contract itself, which is on Github, and on the website. You can buy and sell Unum on the Ropsten network today if you have MetaMask through the Unum website. Buying and selling is done directly on the blockchain, there is no backend to the unum website itself. If you'd prefer, you can also use Mist to interact with the Contract directly.<p>I plan to move to the main Ethereum network soon, baring any major bugs being found.<p>If you're interested more in my thinking behind Unum, you can read the blog post, below, or just ask any questions here.<p><a href="https://github.com/UnumOne/unum" rel="nofollow">https://github.com/UnumOne/unum</a><p><a href="https://medium.com/unum/from-many-unum-8c8493a8db9d" rel="nofollow">https://medium.com/unum/from-many-unum-8c8493a8db9d</a>
