MicroCloud Hologram Inc. (NASDAQ:HOLO) shares jumped about 7.3% after unveiling a post‑quantum cryptography scheme for Bitcoin.
The Strong Designated Verifier Signature scheme uses multivariate polynomial equations, offering NP‑complete security that quantum computers can only accelerate quadratically.
Company holds over $390 million cash and plans to invest more than $400 million in quantum‑secure Bitcoin, quantum computing research and holography.
The protocol can be integrated via a soft‑fork Bitcoin script opcode, targeting privacy‑enhanced transactions and Lightning Network channel closures.
