Pearl (PRL) is a revolutionary Proof-of-Useful-Work (PoUW) Layer-1 blockchain that turns artificial intelligence computations into mining. Instead of useless hashing, Pearl uses matrix multiplication (MatMul) - the main computational load of modern GPUs during neural network training and inference - as its Proof-of-Work.This is a true hybrid: you run real AI tasks (training neural networks) and mine PRL at the same time, getting rewarded for the exact same work. Pearl merges two of the most energy-intensive markets - AI computing and crypto mining - into a single protocol. Thanks to native GPU integration, Pearl brings profitability back to GPU mining in 2026. Now every kilowatt-hour spent on AI can simultaneously generate coins and secure the network.
