BOUNTIES

BuidlGuidl: We used Scaffold-ETH 2 with nextjs & hardhat to build, test and deploy the smart contract that stores the user database and dApp code for accessing the database.

The dApp uses the argon2d password hashing algorithm to hash telegram IDs before storing them onto the chain. The dApp is deployed and hosted using netlify.

ENS: We used ENS for log in and to provide a greater level of trust/verification of wallet holders, as well as auto-filling fields that were available from ENS text records to make the sign up process easier for ENS holders.

We deployed our smart contract onto Sepolia testnet.

iExec: We used iExec to run our Telegram bot daemon on bellecour:

There is a Telegram bot written in nodeJS using the telegram bot APIs, which we have hosted on iExec, and validates user identities by pulling the hashes from the contract using the web3 node.js APIs, and validates each Telegram user against the hashes to confirm identities.

app:    0xB803bb57D3060966f36De13Dfd4f6bD30ea8d0E6

We encountered some service issues with the application dropping unexpectedly, and have been debugging this a bit with the iExec team, but for demo purposes we are running the service on Docker.

Web3privacy Now: Inspired us through their mission and values to come up with an idea that’s new and useful to create privacy a standard within the web3 community. While this is just a small step towards that goal, we are very happy to contribute how we can to a culture governed by healthy values.
