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

Commitment Phase: Miner creates commitment hash = H(problem_params || salt || H(solution))
Reveal Phase: Miner reveals solution after block is mined
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

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

# 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.
