MicroCloud Hologram states that it plans a $400 million Bitcoin protocol research effort using post-quantum signatures alongside ECDSA, underscoring continued industry focus on preparing for potential future quantum threats.
MicroCloud Hologram expanded on its previously reported $400 million plan to strengthen Bitcoin against potential quantum-computing attacks. The Nasdaq-listed company proposed a hybrid cryptographic architecture that would combine post-quantum signatures with the current ECDSA system, and said deployment could use a soft fork with a phased rollout from testnet to mainnet. The update adds implementation details to the company’s earlier proposal for parallel verification and multilayer protection, while the broader topic remains centered on growing concern that future quantum advances could challenge current blockchain cryptography.
