4 Steps to Hosting a Decentralized Static Website using ENS and IPFS


In this article, we will outline the steps required to deploy a static website under your ens name. One example is my personal website hosting on IPFS using “yahsin.eth” my ENS custom domain. What it does is that anyone can visit https://yahsin.eth.link/, the browser would return an introduction of myself. It will work faster if the viewer has MetaMask readily installed. View a list of ENS+IPFS websites compiled by Almonit here: https://almonit.eth.link/
