# COINjecture Commitments Dataset

This dataset contains cryptographic commitments from COINjecture Network B blockchain mining operations.

## Overview

Commitments are created during the mining process where miners commit to NP-complete problem solutions without revealing them immediately. This enables:
- **Fair mining**: Prevents front-running and solution stealing
- **Verifiable work**: Solutions can be verified after commitment
- **Research data**: Provides structured data for NP-complete problem research

## Dataset Structure

Based on the baseline dataset `COINjecture/v5`, this dataset focuses specifically on commitment records.

### Commitment Lifecycle

1. **Commitment Phase**: Miner creates commitment hash = H(problem_params || salt || H(solution))
2. **Reveal Phase**: Miner reveals solution after block is mined
3. **Verification**: Network verifies commitment matches revealed solution

### Schema

Each record contains:
- `commitment_id`: Unique identifier
- `commitment_hash`: Cryptographic hash of the commitment
- `problem_type`: Type of NP-complete problem
- `problem_params`: Problem parameters (JSON)
- `salt`: Random salt for commitment
- `solution_hash`: Hash of solution (H(solution))
- `solution_data`: Actual solution (revealed later, null initially)
- `work_score`: Computed work score
- `status`: Current status (Committed, Revealed, Expired)

## Usage

### Loading the Dataset

```python
from datasets import load_dataset

# Load commitments dataset
dataset = load_dataset("COINjecture/commitments")

# Filter by status
committed = dataset.filter(lambda x: x["status"] == "Committed")
revealed = dataset.filter(lambda x: x["status"] == "Revealed")

# Filter by problem type
sat_commitments = dataset.filter(lambda x: x["problem_type"] == "SAT")
```

### Analyzing Commitments

```python
# Count commitments by status
status_counts = dataset["train"].to_pandas()["status"].value_counts()

# Average work scores by problem type
avg_scores = dataset["train"].to_pandas().groupby("problem_type")["work_score"].mean()
```

## Data Collection

Data is collected in real-time from COINjecture Network B blockchain nodes:
- Commitments are recorded when blocks are mined
- Solutions are revealed in subsequent blocks
- All data is verified against blockchain state

## Baseline Dataset

This dataset is based on `COINjecture/v5` which contains:
- Full problem solutions
- Energy measurements
- Mining metrics
- Block metadata

The commitments dataset focuses specifically on the commitment/reveal mechanism.
