This repository contains a smart contract written in Solidity for managing trust funds and controlling information systems. The contract utilizes zero-knowledge proofs (zkp) to prove login authenticity and provides document storage functionality.
- User Registration: Users can register with a unique username and password.
- User Login: Registered users can log in by providing their username and password, which is authenticated using zero-knowledge proofs.
- User Logout: Logged-in users can log out from the system.
- Document Storage: Logged-in users can store their documents securely.
- Document Retrieval: Logged-in users can retrieve their stored documents.
The smart contract consists of the following major components:
- User Struct: A structure that stores user information including username, password, and login status.
- Users Mapping: A mapping that associates user addresses with their respective User structs.
- Documents Mapping: A mapping that associates user addresses with their stored documents.
- Event: An event that is emitted when a user successfully logs in.
To deploy and interact with the smart contract, follow these steps:
- Clone this repository:
git clone https://github.com/hajihashemabad/TrustFundManagement.git-
Install the necessary dependencies (Solidity compiler, Ethereum development framework, Python zkp library, etc.) as per your environment and project requirements.
-
Compile the smart contract using the Solidity compiler.
-
Deploy the compiled contract to the Ethereum blockchain using your preferred development framework (Truffle, Remix, etc.) or interact with it via a client library (Web3.js, ethers.js, etc.).
-
Implement the
verifyProoffunction in the smart contract, using a Python zkp library (e.g., ZoKrates), to verify the zero-knowledge proof. Replace the placeholder implementation with the actual logic for verifying the proof. -
Update the contract with the actual zero-knowledge proof verification logic in the
verifyProoffunction. -
Test the contract by registering users, logging in, storing documents, and retrieving documents.
The following functions are available in the smart contract:
registerUser(string username, string password): Allows users to register with a unique username and password.login(string username, string password): Enables registered users to log in by providing their username and password.logout(): Allows logged-in users to log out from the system.storeDocument(string document): Enables logged-in users to securely store their documents.retrieveDocument(): Allows logged-in users to retrieve their stored documents.
