Bitcoin was intentionally crafted with a restricted script to diminish the attack surface of the blockchain, enhancing its security and resilience. The QH layer, exemplified by qBTC, introduces programmability atop Bitcoin. QH , intricately connected to Bitcoin through its consensus mechanism known as Proof of Transfer, facilitates the utilization of Bitcoin’s security, allowing QH apps to interact with Bitcoin’s state despite operating on a distinct blockchain. With the Nakamoto release and the introduction of qBTC, a 1-1 Bitcoin-backed asset, QH propels decentralized movement of BTC in and out of Bitcoin layers.
