# COINjecture Rich Emissions Dataset

## Overview

This dataset contains comprehensive emissions and energy consumption data from the COINjecture blockchain network. It captures rich, detailed metrics for every mined block, including:

- **Energy Consumption**: Detailed energy measurements (solve, verify, total)
- **Problem Complexity**: Work scores, complexity weights, and difficulty metrics
- **Time Metrics**: Solve time, verify time, and time asymmetry ratios
- **Block Metadata**: Height, hash, miner address, timestamps
- **Problem Types**: SubsetSum, SAT, TSP, and Custom problem instances
- **Solution Quality**: Solution quality scores and verification results
- **Aggregation Strategies**: Bounty aggregation strategy information

  - `energy_asymmetry`: Ratio of solve to verify energy
- `time_metrics`:
  - `solve_time_us`: Problem solving time in microseconds
  - `verify_time_us`: Verification time in microseconds
  - `time_asymmetry_ratio`: Ratio of solve to verify time
- `complexity_metrics`:
  - `work_score`: Computed work score
  - `complexity_weight`: Problem complexity weight
  - `solution_quality`: Quality score of the solution
- `mining_metadata`:
  - `miner_address`: Address of the miner who solved the problem
  - `nonce`: Mining nonce value
  - `timestamp`: Unix timestamp of block creation

## Use Cases

This dataset is designed for:

1. **Energy Research**: Study energy consumption patterns in blockchain mining
2. **Algorithm Analysis**: Compare performance across different NP-hard problem types
3. **Sustainability Studies**: Analyze the environmental impact of proof-of-work systems
4. **Performance Optimization**: Identify optimization opportunities in mining algorithms
5. **Academic Research**: Support research in distributed systems, cryptography, and computational complexity

## Data Collection

Data is automatically collected and uploaded by COINjecture network nodes running version 4.11.28+. Each node measures energy consumption using configurable methods (estimation or direct measurement) and uploads data in batches to ensure data integrity.
