MicroCloud Hologram Plans $400 Million Investment to Advance Bitcoin Quantum Resistance Upgrade

On April 6, Nasdaq-listed company MicroCloud Hologram Inc. announced plans to invest $400 million in the research and development of a Bitcoin quantum attack resistance protocol, aimed at building a cryptocurrency infrastructure for the “quantum era.” The proposal will adopt a “hybrid encryption architecture,” introducing quantum-resistant signature algorithms alongside traditional ECDSA within the existing transaction system to achieve dual-signature security redundancy, while supporting progressive upgrades to avoid impacting network stability. Technically, the company intends to be compatible with various mainstream post-quantum algorithms, including lattice-based (such as CRYSTALS-Dilithium), hash-based (such as SPHINCS+), and multivariate signature schemes. Through modular design and signature compression techniques, it aims to balance security and performance overhead. At the protocol level, verification logic will be implemented by expanding the scripting system and adding new opcodes, while upgrades will be promoted via a soft fork approach to ensure that old nodes can still participate in consensus, reducing the risk of community fragmentation. Additionally, the company plans to introduce a time-lock mechanism to prevent “delay attacks” (i.e., the potential for future quantum computing capabilities to break historical public keys), and will also advance hardware acceleration, light wallet support, and miner verification optimization. The roadmap indicates that the project will be implemented in phases: first validating on the testnet, then gradually piloting the hybrid signature mechanism on the mainnet, and ultimately completing a comprehensive quantum resistance upgrade with community consensus.
