Steps

What it does

Storing any media on the blockchain is so costly, hence DTube solves this problem by storing IPFS video hashes to the blockchain.
On DTube Nobody can take down your video or ban your account.
It's free to use.
It's truly decentralized.
It's green as compared to the energy consumption of centralized servers.
It's ad-free! Now you can watch videos without those annoying ads, this platform treats you as a "user" not the "product".

How we built it

Tech Stack:

Languages: Solidity, JavaScript, HTML5, CSS3
Libraries: React.js, Web3.js
Tools: IPFS
Network: Polygon (Matic)
Platforms: Ethereum, Fleek

Networks:

Matic Mumbai Test Network
Rinkeby Test Network
Ropsten Test Network
Goerli Test Network

Challenges we ran into

"To make the whole platform decentralized" It was challenging to deploy the whole DTube app to the IPFS. After a lot of experimentation with IPFS, I found that I cannot update/modify the project with the same IPFS hash. After searching online, I landed on "Fleek" IPFS hosting and Filecoin storage platform where you can deploy the project, assign the domain, and update the project by simply connecting the GitHub repository.
Solidity version issues: Every version had syntax differences. Everything worked fine on version 0.5.0.
Matic TestNet error:

Error: Deployment Failed "Migrations" -- only replay-protected (EIP-155) transactions allowed over RPC.

Fix: Fixed this problem by upgrading @truffle/hdwallet-provider version to 1.4.0.

What we learned

It was a great learning journey, I learned so much about blockchain.

What's next for DTube

Updating the smart contracts with more features such as adding descriptions & links to the videos.
Improving speed and overall performance with large video files.
Improving overall UI.

This project was created during the months Jul-Aug (as per browsers 3000 schedules), I submitted this project in ETHOdyssey Hackathon as well. Both Hackathon schedules were the same.
