| ## π 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.
