Introduction: How to Build Quantum-Enhanced Smart Contracts on EpicChain

Building smart contracts with advanced quantum-resistant features and secure asset management capabilities on EpicChain requires a thorough understanding of both blockchain technology and Rust programming. This guide will walk you through the process of developing two key smart contracts for EpicChain: Quantum Guard Nexus and Quantum Vault Asset.

1. Setting Up the Development Environment

Install Rust and ink! Framework:

  1. Install Rust: Download and install Rust from rust-lang.org. Follow the instructions for your operating system.

  2. Install ink! CLI Tools: The ink! framework is used for writing smart contracts in Rust. Install the ink! CLI tools using the following command:

    cargo install cargo-contract

Create a New ink! Project:

  1. Initialize a New Project: Use the ink! CLI to create a new smart contract project:

    cargo contract new quantum_contracts
cd quantum_contracts

2. Developing Smart Contracts

Quantum Guard Nexus Contract:

The Quantum Guard Nexus smart contract provides quantum-resistant cryptographic operations and manages permissions for accessing sensitive data. Here’s how to build it:

  1. Define Storage and Constructor:

    #[ink(storage)]
#[derive(Default, SpreadLayout)]
pub struct QuantumGuardNexus {
    owner: AccountId,
    data: String,
    permission: bool,
}
    • owner: Stores the account ID of the contract owner.
    • data: Holds the sensitive data managed by the contract.
    • permission: Tracks whether access permission is granted.

  2. Implement Functions:

    impl QuantumGuardNexus {
    #[ink(constructor)]
    pub fn new(initial_data: String) -> Self {
        Self {
            owner: Self::env().caller(),
            data: initial_data,
            permission: false,
        }
    }

    #[ink(message)]
    pub fn set_data(&mut self, new_data: String) {
        self.ensure_owner();
        self.data = new_data;
        self.permission = true; // Grant permission after data update
    }

    #[ink(message)]
    pub fn get_data(&self) -> String {
        if !self.permission {
            panic!("Permission denied");
        }
        self.data.clone()
    }

    #[ink(message)]
    pub fn grant_permission(&mut self, granted: bool) {
        self.ensure_owner();
        self.permission = granted;
    }

    #[ink(message)]
    pub fn revoke_permission(&mut self) {
        self.ensure_owner();
        self.permission = false;
    }

    fn ensure_owner(&self) {
        if self.env().caller() != self.owner {
            panic!("Unauthorized access");
        }
    }
}

Quantum Vault Asset Contract:

The Quantum Vault Asset contract is designed for secure asset management, including deposit, withdrawal, and transfer functionalities. Here’s how to build it:

  1. Define Storage and Data Structures:

    #[ink(storage)]
#[derive(Default, SpreadLayout)]
pub struct QuantumVaultAsset {
    owner: AccountId,
    assets: HashMap<AccountId, u64>,
    transaction_log: HashMap<u64, TransactionRecord>,
    transaction_counter: u64,
}

#[derive(Debug, Clone, ink_storage::traits::SpreadLayout)]
#[cfg_attr(feature = "std", derive(scale_info::TypeInfo))]
pub struct TransactionRecord {
    from: AccountId,
    to: AccountId,
    amount: u64,
    timestamp: u64,
}
    • owner: Stores the account ID of the contract owner.
    • assets: A map tracking balances for each account.
    • transaction_log: A log of transactions for transparency.
    • transaction_counter: Counter for transaction IDs.

  2. Implement Functions:

    impl QuantumVaultAsset {
    #[ink(constructor)]
    pub fn new() -> Self {
        Self {
            owner: Self::env().caller(),
            assets: Default::default(),
            transaction_log: Default::default(),
            transaction_counter: 0,
        }
    }

    #[ink(message)]
    pub fn deposit(&mut self, amount: u64) {
        self.ensure_owner();
        let caller = Self::env().caller();
        let balance = self.assets.entry(caller).or_insert(0);
        *balance += amount;
    }

    #[ink(message)]
    pub fn withdraw(&mut self, amount: u64) {
        self.ensure_owner();
        let caller = Self::env().caller();
        let balance = self.assets.entry(caller).or_insert(0);
        if *balance < amount {
            panic!("Insufficient balance");
        }
        *balance -= amount;
    }

    #[ink(message)]
    pub fn transfer(&mut self, to: AccountId, amount: u64) {
        self.ensure_owner();
        let caller = Self::env().caller();
        let sender_balance = self.assets.entry(caller).or_insert(0);
        if *sender_balance < amount {
            panic!("Insufficient balance");
        }
        *sender_balance -= amount;
        let receiver_balance = self.assets.entry(to).or_insert(0);
        *receiver_balance += amount;

        // Log transaction
        self.transaction_counter += 1;
        self.transaction_log.insert(
            self.transaction_counter,
            TransactionRecord {
                from: caller,
                to,
                amount,
                timestamp: Self::env().block_timestamp(),
            },
        );
    }

    #[ink(message)]
    pub fn check_balance(&self) -> u64 {
        let caller = Self::env().caller();
        *self.assets.get(&caller).unwrap_or(&0)
    }

    #[ink(message)]
    pub fn get_transaction_log(&self) -> HashMap<u64, TransactionRecord> {
        self.transaction_log.clone()
    }

    fn ensure_owner(&self) {
        if self.env().caller() != self.owner {
            panic!("Unauthorized access");
        }
    }
}

3. Building and Deploying the Contracts

Build the Contract:

cargo +nightly contract build

Deploy the Contract:

Use EpicChain’s deployment tools or similar interfaces to deploy the compiled contract to the network.

4. Testing the Contracts

Write comprehensive test cases to verify the functionality of your smart contracts. Ensure you cover various scenarios and edge cases.

Example Tests:

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_set_data() {
        let mut contract = QuantumGuardNexus::new(String::from("Initial Data"));
        contract.set_data(String::from("Updated Data"));
        assert_eq!(contract.get_data(), String::from("Updated Data"));
    }

    #[test]
    fn test_permission_management() {
        let mut contract = QuantumGuardNexus::new(String::from("Sensitive Data"));
        contract.grant_permission(true);
        assert_eq!(contract.get_data(), String::from("Sensitive Data"));
        contract.revoke_permission();
        let result = std::panic::catch_unwind(|| contract.get_data());
        assert!(result.is_err());
    }

    #[test]
    fn test_deposit_and_withdraw() {
        let mut contract = QuantumVaultAsset::new();
        contract.deposit(100);
        assert_eq!(contract.check_balance(), 100);
        contract.withdraw(50);
        assert_eq!(contract.check_balance(), 50);
    }

    #[test]
    fn test_transfer_and_logging() {
        let mut contract = QuantumVaultAsset::new();
        let recipient = AccountId::from([0x1; 32]);
        contract.deposit(100);
        contract.transfer(recipient, 50);
        assert_eq!(contract.check_balance(), 50);
        assert_eq!(contract.get_transaction_log().len(), 1);
    }
}
