Inspiration
- Lack of justice around the world. Every country should work on more tools to help its citizens. FBI directories are not very useful if you are searching for someone and the information is private.
- The power of chainlink and the Ethereum network to make everything possible with a lot of powerful minds behind
What it does
It offers the user the possibility of being able to enter the information of a disappeared person, allowing him to enter certain personal information for his recognition as well as an image that is stored in IPFS and coordinates of the places where the person was last seen.
The application allows anyone to enter information about the case and everyone can view it. In case the information is valuable, the creator of the disappearance report can grant a Link token or two depending on the price of the token, the application asks the chainlink oracles for the price of the token and if the token has a value greater than 10 dollars will be given as a reward two tokens, otherwise only 1. Using this formula we prevent blackmailing
How we built it
Our product is implemented on Ethereum’s EVM smart contract platform with Solidity, Hardhat, Chainlink oracles, and Mumbai test net with Alchemy's platform help for deployment. The frontend, where users can interact with the contract, is built in ReactJS Next js and typescript. Web3 app served using Infura IPFS and Fleek
Challenges we ran into
Chainlink integration and Smart contract async functions testing
Accomplishments that we're proud of
I am proud to contribute my knowledge and effort so that our society is less vulnerable to the lack of information related to the integrity of citizens.
What we learned
A bunch of technologies to build better and faster apps that can help the world
What's next for Searching4
The next step will be a platform to track every piece of data related to criminal activities
