# Blockchain And Quantum Computing Are on a Collision Course, Expert Warns. ## When Blockchain Meets Quantum Computing. Herman, Senior Fellow at the Hudson Institute and Director of the Quantum Alliance Initiative, writes that the same technology that could unlock immense computational power might also render existing cryptographic systems, including those that secure blockchain networks, vulnerable to attacks. ## Can Quantum Computing Break Blockchain? Herman’s analysis highlights the inherent risks quantum computing poses to blockchain and cryptocurrencies. ## **The Quantum Threat to Blockchain Security**. “In short, blockchains that use the same cryptographic building blocks as other forms of DLT will be just as much at risk to the quantum computer threat as other digital technologies,” Herman writes. These quantum-resistant algorithms are designed to withstand attacks from quantum computers, making them a crucial component in the next generation of blockchain security. Looking ahead, Herman suggests that a coordinated approach integrating crypto, blockchain and quantum technologies could inaugurate a new era in finance and digital security.

While these developments don’t pose an immediate threat to crypto security, they signal a clear trend: quantum computing is evolving faster than many anticipated, and the crypto industry must address both the challenges and opportunities this presents. According to Project Eleven, a company working on quantum securing crypto currency, and advised by Chainalysis’ former CEO Michael Grønager, approximately $718 billion worth of bitcoin is currently held in addresses that would be vulnerable to quantum attacks, including early Pay-to-Public-Key addresses where public keys are already exposed on the blockchain. Based on our analysis of current quantum computing capabilities, significant technical hurdles remain before quantum computers pose a direct threat to the security and integrity of cryptocurrency networks. Blockchain analytics providers, including Chainalysis, are preparing to support quantum-resistant address formats and transaction types to ensure continuity of compliance and quantum security monitoring capabilities. While quantum computing poses future challenges for cryptocurrency security, the industry has time to prepare. The industry is actively developing post-quantum cryptography to secure blockchain networks.

[Google has led the responsible transition](https://blog.google/innovation-and-ai/technology/safety-security/cryptography-migration-timeline/) to post-quantum cryptography [since 2016](https://security.googleblog.com/2016/07/experimenting-with-post-quantum.html).

We estimate that these circuits can be executed on a superconducting qubit CRQC with fewer than 500,000 physical qubits in a few minutes, given standard assumptions about hardware capabilities that are consistent with some of [Google’s flagship quantum processors](https://blog.google/innovation-and-ai/technology/research/google-willow-quantum-chip/). * [Quantum](https://research.google/blog/label/quantum). * [](https://twitter.com/intent/tweet?text=https%3A//research.google/blog/safeguarding-cryptocurrency-by-disclosing-quantum-vulnerabilities-responsibly/ "Share on Twitter"). * [](https://www.facebook.com/sharer/sharer.php?u=https%3A//research.google/blog/safeguarding-cryptocurrency-by-disclosing-quantum-vulnerabilities-responsibly/ "Share on Facebook"). * [](https://www.linkedin.com/shareArticle?url=https%3A//research.google/blog/safeguarding-cryptocurrency-by-disclosing-quantum-vulnerabilities-responsibly/&mini=true "Share on LinkedIn"). * [](mailto:name@example.com?subject=Check%20out%20this%20site&body=Check%20out%20https%3A//research.google/blog/safeguarding-cryptocurrency-by-disclosing-quantum-vulnerabilities-responsibly/ "Send via Email"). * Algorithms & Theory · * Machine Intelligence](https://research.google/blog/building-better-ai-benchmarks-how-many-raters-are-enough/). .
