💬 ETHTalk

EthTalk is a comments widget implemented and designed for the Ethereum ecosystem built on top of 🏗 Scaffold-ETH, lets visitors leave comments on your website with their non-custodial Ethereum account

Try it yourself: https://ethtalk.app, Demo video: https://www.youtube.com/watch?v=ikJnxQJaxJA

Why ETHTalk?

Basically, for commenting on any website, you need to have a Facebook or Google accounts, or sometimes you need to register a new account with a new username/password which may have a few problems:

1. All the un/pw is controlled by Google, Facebook, or some others and your security hugely depends on them.
2. Most people still have weak passwords, so hackers can still brute-force and gain the access to the accounts.

Would it be better if everyone could have a private key (PK) and use that PK to sign in to a lot of services which is way more secure than the password? The good news is, that has now happened with the power of Ethereum and you can now start using your ETH account to sign in and comment on any website that embedded an ETHTalk's widget (and for a username system you can register your username on the ENS domain which basically is an NFT for your profile and you have full control over it)

I strongly believe that we would see a huge adoption about these ENS and Ethereum Single Sign-on concepts in the near future (maybe about 1-3 years from now) and this project is the one that leveraged those ideas and bring them into action, and to make that adoption happen, I'll start using it on my personal website first 😎

Features

• LaTex supported for commenting 🧮
• All the data is stored on Firebase Firestore 💽

More fun ideas (feel free to contribute)

• Add verify badge for who have done Proof of Humanity
• Buy me a beer, send 🍺 (1x🍺 = 0.001 ETH) directly within a comment for patronizing the author
• Use your NFTs as a sticker

Contribution

How it works?

1. User connect their wallet to give a public address to the site
2. Frontend send that public address to get a challenge code (nonce) from the backend
3. Frontend give the challenge code to the wallet to sign a message with PK 🔑
4. Frontend submit that signed message to the backend
5. Backend received the message, proof validity, and generate a new JWT custom token to frontend
6. Frontend use that token to sign in (using Firebase Custom Authentication)
7. Now the user can comment, like, and reply on the web 😎
