Qbit, a post-quantum UTXO testnet looking for technical review

- **Qbit** is a new testnet (experimental blockchain) that aims to be "post-quantum" — secure against attacks from future quantum computers, which could break the cryptography used by Bitcoin and most current blockchains. - It uses the **UTXO model** (Unspent Transaction Output), the same accounting system Bitcoin uses, where each transaction consumes previous outputs and creates new ones. - The project is asking for "technical review" — meaning it's at an early stage and seeking feedback from developers and cryptographers, not ready for real-world use. - Post-quantum cryptography is a growing field: many projects (e.g., Bitcoin, Ethereum) are researching how to migrate, but no major blockchain has fully done so yet. Qbit is an attempt to build a blockchain designed for it from the start.
