Core Implementation Details

Block Structure and Implementation

The core block structure is implemented with comprehensive validation and serialization mechanisms:

pub struct Block {
    header: BlockHeader,
    transactions: Vec<Transaction>,
}

impl Block {
    pub fn new(
        version: u32,
        prev_block_hash: [u8; 32],
        transactions: Vec<Transaction>,
        target: u32,
    ) -> Self {
        let merkle_root = Self::calculate_merkle_root(&transactions);
        
        Self {
            header: BlockHeader::new(version, prev_block_hash, merkle_root, target),
            transactions,
        }
    }

    pub fn hash(&self) -> [u8; 32] {
        self.header.hash()
    }

    pub fn increment_nonce(&mut self) {
        self.header.increment_nonce();
    }

    fn calculate_merkle_root(transactions: &[Transaction]) -> [u8; 32] {
        let tx_bytes: Vec<Vec<u8>> = transactions
            .iter()
            .map(|tx| bincode::serialize(&tx).unwrap())
            .collect();

        let tree = MerkleTree::new(&tx_bytes);
        tree.root_hash().unwrap_or([0u8; 32])
    }

    pub fn validate(&self) -> bool {
        let hash = self.header.hash();
        let target = self.header.target;
        
        let hash_value = u32::from_be_bytes([hash[0], hash[1], hash[2], hash[3]]);
        
        if hash_value > target {
            return false;
        }

        let calculated_root = Self::calculate_merkle_root(&self.transactions);
        if calculated_root != self.header.merkle_root {
            return false;
        }

        true
    }
}

Mining System

The mining system implements a multi-threaded approach to find valid blocks:

// Worker implementation for mining a block
pub struct MiningWorker {
    id: usize,
    template: Arc<BlockTemplate>,
    max_nonce: u32,
    metrics: Arc<MiningMetrics>,
}

impl MiningWorker {
    pub fn run(&mut self) -> Option<Block> {
        let mut block = self.template.create_block();
        let target_hash = block.target();
        let start_time = Instant::now();
        let mut hashes = 0;
        
        for nonce in 0..self.max_nonce {
            block.set_nonce(nonce);
            let hash = block.hash();
            hashes += 1;
            
            if hash_meets_target(&hash, target_hash) {
                self.metrics.report_block_found(self.id, nonce, start_time.elapsed());
                return Some(block);
            }
            
            // Update metrics periodically
            if hashes % 10000 == 0 {
                self.metrics.update_hash_rate(self.id, hashes, start_time.elapsed());
                hashes = 0;
            }
        }
        
        None
    }
}

Transaction Processing System

The transaction system implements comprehensive UTXO management and validation:

pub struct Transaction {
    version: u32,
    inputs: Vec<TransactionInput>,
    outputs: Vec<TransactionOutput>,
    locktime: u32,
}

impl Transaction {
    pub fn new(
        version: u32,
        inputs: Vec<TransactionInput>,
        outputs: Vec<TransactionOutput>,
        locktime: u32,
    ) -> Self {
        Self {
            version,
            inputs,
            outputs,
            locktime,
        }
    }
    
    pub fn hash(&self) -> [u8; 32] {
        let mut hasher = Sha256::new();
        hasher.update(&bincode::serialize(&self).unwrap());
        let result = hasher.finalize();
        let mut hash = [0u8; 32];
        hash.copy_from_slice(&result);
        hash
    }
    
    pub fn calculate_fee_rate(&self, get_output: impl Fn(&[u8; 32], u32) -> Option<TransactionOutput>) -> Option<u64> {
        let mut input_value = 0;
        for input in &self.inputs {
            let outpoint = &input.outpoint;
            let output = get_output(&outpoint.txid, outpoint.vout)?;
            input_value += output.value;
        }
        
        let output_value: u64 = self.outputs.iter().map(|o| o.value).sum();
        if input_value <= output_value {
            return None;
        }
        
        let fee = input_value - output_value;
        let size = bincode::serialize(&self).ok()?.len() as u64;
        
        if size == 0 {
            return None;
        }
        
        Some(fee / size)
    }
}

Advanced Difficulty Adjustment

The difficulty adjustment algorithm provides target calculation:

// Difficulty adjustment algorithm
pub struct DifficultyAdjuster {
    timestamps: Vec<u64>,
    target_timespan: u64,
    last_adjustment_time: u64,
    current_target: u32,
}

impl DifficultyAdjuster {
    pub fn new(initial_target: u32, target_timespan: u64) -> Self {
        Self {
            timestamps: Vec::new(),
            target_timespan,
            last_adjustment_time: SystemTime::now()
                .duration_since(UNIX_EPOCH)
                .unwrap()
                .as_secs(),
            current_target: initial_target,
        }
    }
    
    pub fn add_block_timestamp(&mut self, timestamp: u64) {
        self.timestamps.push(timestamp);
        
        // Keep only the last N timestamps
        const MAX_TIMESTAMPS: usize = 100;
        if self.timestamps.len() > MAX_TIMESTAMPS {
            self.timestamps.remove(0);
        }
    }
    
    pub fn adjust_difficulty(&mut self, height: u64) -> u32 {
        if height % 10 != 0 || self.timestamps.len() < 10 {
            return self.current_target;
        }
        
        let mut timestamps = self.timestamps.clone();
        timestamps.sort();
        
        // Get median time
        let median_index = timestamps.len() / 2;
        let median_time = timestamps[median_index];
        
        // Calculate actual timespan
        let actual_timespan = median_time - self.last_adjustment_time;
        
        // Update last adjustment time
        self.last_adjustment_time = median_time;
        
        // Adjust target based on ratio of actual to target timespan
        let mut new_target = self.current_target;
        
        if actual_timespan < self.target_timespan / 4 {
            // Time is too short, increase difficulty
            new_target = new_target.saturating_sub(new_target / 4);
        } else if actual_timespan > self.target_timespan * 4 {
            // Time is too long, decrease difficulty
            new_target = new_target.saturating_add(new_target / 4);
        } else {
            // Normal adjustment
            let ratio = actual_timespan as f64 / self.target_timespan as f64;
            let adjustment = (self.current_target as f64 * (ratio - 1.0)) as i32;
            new_target = (self.current_target as i32 + adjustment) as u32;
        }
        
        self.current_target = new_target;
        new_target
    }
}

UTXO Set Management

Efficient UTXO tracking and state management:

pub struct ChainState {
    db: Arc<BlockchainDB>,
    utxo_set: Arc<DashMap<OutPoint, TransactionOutput>>,
    height: AtomicU64,
    best_block_hash: RwLock<[u8; 32]>,

}

Advanced Cryptographic Features

Supernova integrates forward-looking cryptographic features to enhance privacy and future-proof the blockchain against quantum attacks:

Post-Quantum Cryptography

The blockchain implements multiple quantum-resistant signature schemes to ensure security in a post-quantum era:

/// Supported quantum-resistant signature schemes
#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum QuantumScheme {
    /// CRYSTALS-Dilithium signature scheme
    Dilithium,
    /// FALCON signature scheme
    Falcon,
    /// SPHINCS+ signature scheme
    Sphincs,
    /// Hybrid scheme (classical + post-quantum)
    Hybrid(ClassicalScheme),
}

pub struct QuantumKeyPair {
    /// The public key
    pub public_key: Vec<u8>,
    /// The private key (sensitive information)
    private_key: Vec<u8>,
    /// Parameters used for this key pair
    pub parameters: QuantumParameters,
}

impl QuantumKeyPair {
    /// Sign a message using the quantum-resistant secret key.
    pub fn sign(&self, message: &[u8]) -> Result<Vec<u8>, QuantumError> {
        match &self.parameters.scheme {
            QuantumScheme::Dilithium => {
                match self.parameters.security_level {
                    SecurityLevel::Low => {
                        let sk = pqcrypto_dilithium::dilithium2::SecretKey::from_bytes(&self.private_key)
                            .map_err(|e| QuantumError::InvalidKey(format!("Invalid Dilithium secret key: {}", e)))?;
                        let signature = pqcrypto_dilithium::dilithium2::detached_sign(message, &sk);
                        Ok(signature.as_bytes().to_vec())
                    },
                    // Additional security levels...
                }
            },
            QuantumScheme::Falcon => {
                // Implementation for Falcon would go here
                // For now, return CryptoOperationFailed error with an informative message
                Err(QuantumError::CryptoOperationFailed("Falcon signature implementation pending".to_string()))
            },
            // Other schemes...
        }
    }
    
    /// Verify a signature using the quantum-resistant public key.
    pub fn verify(&self, message: &[u8], signature: &[u8]) -> Result<bool, QuantumError> {
        // Implementation for verification...
    }
}

Environmental Impact Measurement System

The blockchain includes comprehensive features for tracking and mitigating environmental impact:

/// Emissions tracker for the Supernova network
pub struct EmissionsTracker {
    /// Network hashrate by geographic region
    region_hashrates: HashMap<Region, HashRate>,
    /// Emissions factors by region (gCO2e/kWh)
    region_emission_factors: HashMap<Region, EmissionFactor>,

API Implementation

Supernova features a comprehensive API system that provides both RESTful and JSON-RPC interfaces for interacting with the blockchain. This implementation enables seamless integration with exchanges, wallets, and other blockchain services.

API Architecture

The API system is built with a modular design, ensuring clean separation of concerns:

//! API routes
//!
//! This module defines the API routes for the Supernova blockchain node.

pub mod blockchain;
pub mod mempool;
pub mod network;
pub mod mining;
pub mod environmental;
pub mod lightning;
pub mod node;
pub mod wallet;

use actix_web::web;

/// Configure all API routes
pub fn configure(cfg: &mut web::ServiceConfig) {
    // Configure API v1 routes
    cfg.service(
        web::scope("/api/v1")
            .configure(blockchain::configure)
            .configure(mempool::configure)
            .configure(network::configure)
            .configure(mining::configure)
            .configure(environmental::configure)
            .configure(lightning::configure)
            .configure(node::configure)
            .configure(wallet::configure)
    );
    
    // Add health check endpoint at root
    cfg.route("/health", web::get().to(health_check));
}

Each API module follows a consistent pattern of route configuration, request handling, and response formatting, making the codebase maintainable and extensible. The system uses Actix Web, a powerful, high-performance web framework for Rust, to deliver exceptional throughput and low latency even under high load.

RESTful API Implementation Details

The Supernova API system uses a typed architecture with comprehensive validation at every level. The core of this implementation includes:

Standard Response Pattern

All API responses follow a standardized format for consistency:

/// Standard API response wrapper
#[derive(Debug, Serialize, Deserialize, ToSchema)]
pub struct ApiResponse<T> {
    /// Whether the request was successful
    pub success: bool,
    /// Response data (only present if success is true)
    #[serde(skip_serializing_if = "Option::is_none")]
    pub data: Option<T>,
    /// Error message (only present if success is false)
    #[serde(skip_serializing_if = "Option::is_none")]
    pub error: Option<String>,
}

impl<T> ApiResponse<T> {
    /// Create a successful response
    pub fn success(data: T) -> Self {
        Self {
            success: true,
            data: Some(data),
            error: None,
        }
    }
    
    /// Create an error response
    pub fn error(message: impl Into<String>) -> Self {
        Self {
            success: false,
            data: None,
            error: Some(message.into()),
        }
    }
}

Wallet API Implementation

The wallet API module provides comprehensive functionality for wallet management:

/// Configure wallet API routes
pub fn configure(cfg: &mut web::ServiceConfig) {
    cfg.service(
        web::scope("/wallet")
            .route("/info", web::get().to(get_wallet_info))
            .route("/balance", web::get().to(get_wallet_balance))
            .route("/addresses", web::get().to(list_addresses))
            .route("/addresses/{address}", web::get().to(get_address_info))
            .route("/addresses/new", web::post().to(create_new_address))
            .route("/transactions", web::get().to(list_transactions))
            .route("/transactions/{txid}", web::get().to(get_transaction_info))
            .route("/utxos", web::get().to(list_utxos))
            .route("/send", web::post().to(send_transaction))
            .route("/sign", web::post().to(sign_message_or_tx))
            .route("/verify", web::post().to(verify_message))
            .route("/label", web::post().to(set_address_label))
            .route("/lock", web::post().to(lock_wallet))
            .route("/unlock", web::post().to(unlock_wallet))
            .route("/backup", web::post().to(create_backup)),
    );
}

Each endpoint is implemented with comprehensive error handling, input validation, and type safety. For example, the implementation of the create_new_address endpoint:

/// Create a new address
#[utoipa::path(
    post,
    path = "/api/v1/wallet/addresses/new",
    request_body = AddressRequest,
    responses(
        (status = 200, description = "Address created successfully", body = ApiResponse<AddressResponse>),
        (status = 400, description = "Invalid request", body = ApiError),
        (status = 401, description = "Unauthorized", body = ApiError),
        (status = 500, description = "Internal server error", body = ApiError)
    ),
    security(
        ("api_key" = [])
    )
)]
pub async fn create_new_address(
    node: web::Data<Arc<Node>>,
    req: web::Json<AddressRequest>,
) -> ApiResult<impl Responder> {
    debug!("Create new address: {:?}", req);
    
    // Get wallet from node
    let wallet = node.get_wallet()
        .ok_or_else(|| ApiError::internal("Wallet not available"))?;
    
    // Apply request parameters
    let label = req.label.clone();
    let address_type = req.type_.clone().unwrap_or_else(|| "receive".to_string());
    let quantum_resistant = req.quantum_resistant.unwrap_or(false);
    
    // Create new address
    let address_response = wallet.create_new_address(&address_type, &label, quantum_resistant)
        .map_err(|e| ApiError::internal(format!("Error creating address: {}", e)))?;
    
    Ok(HttpResponse::Ok().json(ApiResponse::success(address_response)))
}

The API embraces modern Rust development practices with:

Async/await for non-blocking operation
Type-safe error handling with Result types
OpenAPI documentation with utoipa
Comprehensive logging
Secure dependency injection
Proper resource cleanup

Comprehensive Type System

The API system defines a rich set of data types for request/response handling, ensuring type safety and proper serialization:

/// Transaction information
#[derive(Debug, Clone, Serialize, Deserialize, ToSchema)]
pub struct Transaction {
    /// Transaction ID
    pub txid: String,
    
    /// Timestamp
    pub time: String,
    
    /// Amount in satoshis (positive for receive, negative for send)
    pub amount: i64,
    
    /// Fee in satoshis
    pub fee: u64,
    
    /// Number of confirmations
    pub confirmations: u32,
    
    /// Block height
    pub height: Option<u32>,
    
    /// Block hash
    pub blockhash: Option<String>,
    
    /// Transaction category (send, receive, generate, immature, fee)
    pub category: String,
    
    /// Address (primary address for transaction)
    pub address: Option<String>,
    
    /// Label (user-defined)
    pub label: Option<String>,
    
    /// Transaction inputs
    pub inputs: Vec<TransactionInput>,
    
    /// Transaction outputs
    pub outputs: Vec<TransactionOutput>,
    
    /// Carbon footprint of the transaction
    pub carbon_footprint: Option<CarbonFootprint>,
    
    /// Raw transaction hex (if requested)
    pub raw: Option<String>,
}

Disaster Recovery

Supernova incorporates a robust disaster recovery system designed to handle various types of data corruption and system failures. The system is built around the following key components:

Corruption Detection

Automated integrity checks for database consistency
Real-time monitoring of database operations
Detection of multiple corruption types:
- File-level corruption (damaged or missing files)
- Record-level corruption (individual corrupted records)
- Index corruption (damaged database indexes)
- Logical corruption (inconsistencies in blockchain state)
- Checkpoint corruption (damaged recovery points)

Recovery Strategies

The system implements several recovery strategies based on the type and severity of corruption detected:

Restore from Backup: Complete restoration from the most recent valid backup
Rebuild Corrupted Records: Targeted repair of specific corrupted database entries
Rebuild Indexes: Reconstruction of damaged database indexes while preserving core data
Revert to Checkpoint: Rolling back to the last verified consistent state
Rebuild Chain State: Complete reconstruction of blockchain state from genesis

CorruptionHandler Implementation

Supernova's CorruptionHandler provides:

Automated selection of optimal recovery strategy based on corruption type
Checkpoint management for rapid recovery to known-good states
Detailed logging of corruption events and recovery attempts
Configurable retry policies for repair operations
Notification system for critical corruption events

Preventive Measures

Automatic creation of regular database checkpoints
Scheduled integrity checks to detect corruption early
Incremental backups of critical data
Redundant storage of blockchain state

This comprehensive approach ensures high availability and data integrity even in the face of hardware failures, network issues, or software bugs.
