MicroCloud Hologram Inc. (HOLO) announced on Monday that it will invest $400 million in developing a quantum-resistant update for Bitcoin (BTC), aiming to defend the network from possible dangers posed by future quantum computer developments.
The company stated that it will focus on developing a hybrid cryptographic architecture that will allow both existing and post-quantum signature methods to operate concurrently. This dual-signing strategy is intended to provide more security while allowing for a gradual transition, minimizing disturbance to the current Bitcoin ecosystem.
MicroCloud said it plans to support several post-quantum cryptography approaches and uses a modular design to keep the blockchain from becoming too large while remaining secure and efficient. It added that a soft fork is likely how the upgrade will be done.
The company stated it would provide new verification tools while keeping compatibility with existing nodes. The rollout will happen in stages, starting with testnet trials, then moving to mainnet integration, and finally a larger update that everyone agrees on, with support from hardware acceleration and improved infrastructure.
HOLO’s stock was up over 3% on Monday morning trade amid strength in the broader market. The stock, which has a market cap of around $47 million, was down over 22% year-to-date.

On Stocktwits, retail sentiment around HOLO remained dropped to ‘bullish’ from ‘extremely bullish’ territory, while chatter moved to ‘high’ from ‘extremely high’ levels over the past day.
The initiative comes as the industry focuses on quantum hazards to cryptographic systems.
Coinbase (COIN) CEO Brian Armstrong recently stated that he will lead efforts to make Bitcoin quantum-resistant. Last week, on X, Armstrong said he would “start spending time on this personally,” adding that Bitcoin’s quantum risk “needs to be solved sooner rather than later.”

His comments came after Google (GOOGL/ GOOG) Quantum AI published a study presenting a theoretical system capable of breaching Bitcoin's elliptic curve cryptography using Shor's Algorithm.
The report said that hackers would be able to use new quantum computing techniques to crack open wallets belonging to Bitcoin investor Satoshi Nakamoto in as little as nine minutes.
