RinHash CUDA Implementation

🚀 High-performance GPU implementation of RinHash – an ASIC-resistant hashing algorithm designed for RinCoin mining.

🔧 Algorithm Overview

RinHash is a custom Proof-of-Work algorithm designed to resist ASICs by combining three cryptographic hash functions:

1. BLAKE3 – Fast and modern hashing.
2. Argon2d – Memory-hard password hashing (64KB, 2 iterations).
3. SHA3-256 – Secure final hash.

The final output is a 32-byte SHA3-256 digest of the Argon2d result, which itself is applied to the BLAKE3 hash of the input block header.
