What is qPoW?
Quantum Proof of Work replaces “guess a random number” with “simulate a quantum circuit.”
When you mine Qubitcoin, your GPU doesn't grind SHA-256 hashes endlessly. Instead, it runs a 16- quantum circuit made of rotation gates (Ry, Rz) and entanglement gates (). The angles for each gate come from hashed block data, so every block produces a unique circuit.
After the simulation, the quantum state's expectation valuesare compressed into a 256-bit hash. If that hash meets the network's difficulty target, you've found a block and earn QTC.
