OpenSky, decentralized, uncensorable CMS for your blog

https://www.opensky.io/

Write your content on Matic, Deploy it to IPFS, Pair your Address and Twitter Account with Chainlink

Using TheGraph for the best UX

Built for the Chainlink Hackathon Mar / Apr 2021

Technologies

• Docker (image to build your blog and deploy it to IPFS)
• IPFS to deploy your blog (through Pinata)
• Hardhat, smart contract development and testing
• NextJS, frontend
• TheGraph, to track new articles
• Create React App, for default blog template (built and deployed by the Docker Image)
• Matic, the contracts are deployed on Matic to have faster block time (2 s) and cheaper gas (Writing 20 paragraphs on chain costs less than a cent)

This is a monorepo for the OpenSky CMS website, containing:

hardhat

The contracts, with tests and tasks to publish new content, using Solidity Template

next

The UI for the website, to interact with the protocol and publish new content, using NextJS

subgraph

The subgraph code to track new posts, using TheGraph
