Defending Digital Assets Against Quantum Threats
A global alliance of financial institutions, miners, and researchers building quantum-resistant infrastructure for Bitcoin.
Alliance Members
What Is QDefence?
A recoverable, post-quantum backup record for Bitcoin—ensuring asset integrity even if traditional cryptography is compromised.
We are an alliance of major financial institutions, miners, and research universities dedicated to preserving the global financial system against quantum threats.

Quantum Computers Are Advancing Rapidly
Recent breakthroughs in qubit scaling and error correction are accelerating the timeline for quantum systems capable of compromising classical cryptographic signatures.
Bitcoin's Legacy UTXOs Are Exposed
Early address formats such as P2PK and reused public keys expose significant holdings to potential quantum attacks if proactive migration is not undertaken.
Institutional Assets Require Protection
Corporate treasuries, mining operations, and custodial exchanges hold billions in digital assets that demand quantum-resistant security measures ahead of emerging threats.
The Role of the Alliance
Global Coordination
QDefence unites institutions across finance, mining, custody, academia, and quantum science to establish shared defense strategies and industry-wide standards.
Scientific Advisory Council
The alliance is guided by leading quantum researchers, cryptographers, and academic institutions providing technical insight and independent validation.
Quantum Risk Intelligence
QDefence maintains a public risk explorer powered by on-chain analysis, enabling transparent visibility into quantum-exposed Bitcoin addresses.
Quantum Risk Dashboard
Real-time monitoring and assessment of Bitcoin's quantum vulnerability exposure across the network.
