# BTCBANG

> BTCBANG is the Bitcoin block-hash variant of the BNBBANG browser universe simulator, hosted at bang.satloot.com. It offers Chinese and English introductions, simulation documentation, optional NFT minting, and a marketplace.

BTCBANG uses Bitcoin block hashes as the input to a virtual universe simulation. It shares the BNBBANG simulation engine and the published BNBBANG NFT and BANG token system on BNB Smart Chain; it does not introduce a separate BTCBANG token. The simulation is an entertainment experience, not a scientific prediction or a promise of financial returns. Bitcoin block confirmations, minting eligibility, allowances, and transaction costs follow the current documentation and contract state.
