πŸ”¬ COINjecture NP Solutions Dataset v3

Institutional-Grade Blockchain Research Data

License: MIT Data Version Update Frequency Genesis

A comprehensive, real-time dataset of NP-complete problem solutions generated through Proof-of-Useful-Work (PoUW) blockchain consensus

Overview β€’ Data Schema β€’ Metrics β€’ Pipeline β€’ Usage β€’ Citation

πŸ“‹ Overview

This dataset contains institutional-grade metrics from the COINjecture Network B blockchain, which implements a novel Proof-of-Useful-Work (PoUW) consensus mechanism. Unlike traditional Proof-of-Work systems that compute arbitrary hashes, COINjecture miners solve genuine NP-complete computational problems, producing verifiable solutions with real-world applicability.
