On April 6th, MicroCloud Hologram Inc., a company listed on Nasdaq, announced plans to invest $400 million in research and development of a quantum-resistant protocol for Bitcoin, aimed at creating a cryptocurrency infrastructure for the "quantum era." The proposal will include a "hybrid encryption architecture," introducing quantum-resistant signature algorithms alongside traditional ECDSA within the existing transaction system to achieve double-layer security with dual signatures, while supporting progressive upgrades to avoid impacting network stability. Technically, the company intends to be compatible with various major 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. At the protocol level, verification logic will be implemented by extending the scripting system and adding new opcodes, with updates promoted via a soft fork approach to ensure that older nodes can still participate in consensus, reducing the risk of community fragmentation. Additionally, the company plans to introduce a lock-in mechanism to prevent "delay attacks" (i.e., the potential ability of future quantum computing power to break historical public keys), as well as promote hardware acceleration, support for lightweight wallets, and miner verification optimization. The roadmap indicates that the project will be implemented in phases: first validation on the testnet, then gradual piloting of the hybrid signature mechanism on the mainnet, and ultimately completing a comprehensive quantum resistance upgrade with community consensus.
