About

BlogChain is a decentralized blogging platform built on the Ethereum blockchain. It is the first of its kind to implement the Sign-In with Ethereum authentication protocol, natively in Python using the siwe-py library. On the core, it is built using the Flask web framework.

It supports Ethereum based user authentication, setting username, creating and updating blog posts, and viewing blog posts. On top of that, it supports tipping post authors in order to incentivize blogging.
