Svmuu News Nasdaq-listed company MicroCloud Hologram announced it will invest $400 million to upgrade the Bitcoin protocol to defend against quantum attacks. The company plans to develop a quantum-resistant protocol based on a multi-layer hybrid encryption architecture. This protocol will introduce a parallel verification mechanism on top of the existing Bitcoin transaction structure to validate both post-quantum signature algorithms and traditional signature algorithms. Under this framework, users can opt to use both ECDSA and quantum-resistant signature algorithms for dual signatures, thereby achieving security redundancy before quantum threats become fully realized. It is reported that this hybrid signature strategy can not only enhance the system's resistance to attacks but also provide ample transition time for network upgrades, avoiding the systemic risks associated with a one-time replacement.
