Mining Difficulty Adjustment

TOS Network implements an advanced mining difficulty adjustment mechanism that maintains consistent block times while adapting to network hash rate changes. This system ensures network stability and fair mining distribution across all participants.

Overview

The TOS Network difficulty adjustment algorithm is designed around the core principle of “Don’t Trust, Verify it” - every adjustment is mathematically verifiable and transparent to all network participants.

Key Features

• Dynamic Adjustment: Real-time difficulty adaptation based on network conditions
• Mining Optimization: Special considerations for GPU mining algorithms
• Predictable Block Times: Target block time of 1 second with minimal variance
• Hash Rate Stability: Smooth difficulty transitions prevent mining pool disruption
• Energy Efficiency: Optimized for the TOS Energy Model integration

Difficulty Calculation Algorithm

Basic Formula

TOS Network uses a modified version of the Kimoto Gravity Well algorithm with mining optimizations:

new_difficulty = old_difficulty * (target_time / actual_time) * adjustment_factor

Where:

• target_time = 1 second (target block time)
• actual_time = Average time of last N blocks
• adjustment_factor = Smoothing factor to prevent extreme adjustments

Implementation Details

// Simplified difficulty adjustment implementation
pub fn calculate_next_difficulty(
    current_difficulty: u64,
    block_times: &[u64],
) -> u64 {
    const TARGET_BLOCK_TIME: u64 = 1; // seconds
    const ADJUSTMENT_WINDOW: usize = 2160; // ~36 minutes
    const MAX_ADJUSTMENT: f64 = 4.0; // Max 4x change
    const MIN_ADJUSTMENT: f64 = 0.25; // Min 0.25x change
 
    // Calculate average block time
    let average_time = block_times.iter().sum::<u64>() as f64 / block_times.len() as f64;
 
    // Base adjustment ratio
    let time_ratio = TARGET_BLOCK_TIME as f64 / average_time;
 
    // Apply smoothing and limits
    let adjustment = time_ratio.clamp(MIN_ADJUSTMENT, MAX_ADJUSTMENT);
 
    (current_difficulty as f64 * adjustment) as u64
}
