Introducción
HASH is a browser-mined quantum token based on the Ethereum mainnet. Its development references the SPHINCS+ post-quantum hash signature scheme code pushed by Vitalik Buterin. This token integrates ERC20, Uniswap V4 hook, and keccak256 proof-of-work, using browser-based brute-force keccak256 mining. It employs address-binding challenges, epoch rotation, and halving mechanisms, optimizing browser mining efficiency.
