US EditionBlackRock Issues Rare Warning: Is Bitcoin’s Future at Risk From Quantum Tech?
- BlackRock, the world’s largest asset manager, issued a warning on May 2025 about quantum computing's potential threat to Bitcoin in the US ETF prospectus.
- This alert follows advances in quantum algorithms like Shor's, which could break Bitcoin's core cryptography including SHA-256 and ECDSA used for transaction security.
- Experts note that over 5.9 million BTC use older wallets vulnerable to quantum attacks, and shifting Bitcoin's protocol to quantum-resistant methods faces technical challenges.
- Google researchers reduced quantum hardware requirements from 20 million to under one million qubits, making Bitcoin’s encryption potentially 20x easier to crack, accelerating the timeline.
- The industry sees this as a serious long-term risk, prompting development of post-quantum cryptography to secure Bitcoin, though full implementation remains complex and urgent.

Quantum Computing Is Threat To BTC: BlackRock
BlackRock, the world’s largest asset manager, has issued a warning regarding the potential threat of quantum computing to Bitcoin (BTC) and other digital assets. In a recent update to its iShares Bitcoin Trust ETF (IBIT) prospectus, BlackRock explicitly included quantum computing as a risk factor, stating that it could render Bitcoin’s source code “flawed or ineffective. It means, if quantum technology advances sufficiently, it could compromise …
Bitcoin vs Quantum Computing: Will BlackRock’s Warning Come True? - THE iBULLETIN
Yes, quantum computers could break Bitcoin’s current security someday, but the industry still has time and clear paths to defend the network if it starts preparing now. Bitcoin has faced plenty of doubters, yet the latest alarm comes from an unlikely place: BlackRock. In a recent filing the asset-management giant flagged the risk that future quantum computers might crack Bitcoin’s core cryptography and crash the price toward forty thousand doll…
Blackrock’s Updated Bitcoin ETF Prospectus Reveals Hidden Danger: Quantum Hack Risk - Coin Surges
A freshly revised prospectus for Blackrock’s Ishares Bitcoin Trust (IBIT) now includes a cautionary note that the advent of powerful quantum computing—and related developments—could render Bitcoin’s foundational cryptographic safeguards “becoming ineffective.” Blackrock Flags Quantum Computing Risk This week, the debate around quantum computing and Bitcoin has reignited within the crypto sphere, with renewed speculation over […] Read Entire Arti…
