I have been working on a project in which i needed my users to login with an Ethereum address so that i am able to map the users with their corresponding Ethereum Address. I needed to do this in a way that there are no transaction fees involved and such that they don't have to be tied to a certain device with MetaMask.
So i built Dauth (https://dauth.co) which is similar to OAuth, but i tried to keep the architecture as opely decentralizable as i could.
I'd love to hear feedback on this.
A blog post i wrote on the same topic : https://medium.com/madhavanmalolan/login-with-ethereum-e6dbd408d46c
And, no this isn't an ICO.
