PANews reported on April 6th, citing Prnewswire, that Nasdaq-listed MicroCloud Hologram announced a $400 million investment to upgrade the Bitcoin protocol to resist quantum attacks. The company plans to develop a quantum-resistant protocol based on a multi-layered hybrid cryptographic architecture. This protocol introduces a parallel verification mechanism on top of the existing Bitcoin transaction structure to verify both post-quantum signature algorithms and traditional signature algorithms. Under this framework, users can choose to use both ECDSA and quantum-resistant signature algorithms for dual signatures, thus achieving security redundancy before the full manifestation of quantum threats. This hybrid signature strategy not only enhances the system's resistance to attacks but also provides ample transition time for network upgrades, avoiding the systemic risks of a one-time replacement.
