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

April 6th, Nasdaq-listed MicroCloud Hologram Inc. announced plans to invest $400 million in researching and developing the Bitcoin Post-Quantum Attack Protocol, aiming to advance the buildout of encryption infrastructure for the “quantum era.” The initiative will use a “hybrid encryption architecture”—integrating a post-quantum signature algorithm into the existing transaction system to run in parallel with traditional ECDSA, adding dual-signature security redundancy. It also supports progressive upgrades to avoid disrupting network stability. On the technical front, the company aims to be compatible with leading post-quantum algorithms, including lattice-based (e.g., CRYSTALS-Dilithium), hash-based (e.g., SPHINCS+), and multivariate signature schemes. Via modular design and signature compression, it will balance security and performance overhead. At the protocol level, validation logic will be implemented via an extended script system and new opcodes. Upgrades will roll out via a soft fork to ensure old nodes can still participate in consensus, minimizing the risk of community fragmentation. Additionally, the company plans to add a time-lock mechanism to prevent “delay attacks”—defined as cracking historical public keys once future quantum computing capabilities mature. It will also push for hardware acceleration, lightweight wallet support, and miner verification optimizations. Per the roadmap, the project will roll out in phases: first, validation on the testnet; next, gradual piloting of the hybrid signature mechanism on the mainnet; and finally, a full post-quantum upgrade under community consensus.
