Quantum and Post-Quantum Blockchain: A Systematic Survey

Paper

https://eprint.iacr.org/2026/1017

Ruwanga Konara Quantum Blockchain

Konara et al. systematically reviewed quantum and post-quantum blockchains, analyzing the integration of post-quantum cryptography and the state of quantum blockchains in their paper.

Notes

Quantum computing poses a fundamental threat to blockchain’s classical cryptography.
Extensive research integrates post-quantum cryptosystems into blockchain for quantum resistance.
Various post-quantum blockchain solutions exist, but standardization and practicality are evolving.
Quantum blockchains leverage quantum technologies for forward compatibility with the quantum internet.
This survey comprehensively reviews both post-quantum and quantum blockchain research.

Why does quantum computing threaten blockchains?

Quantum algorithms may break ECC and RSA, threatening wallet security and transaction signatures used in blockchains.

What is the difference between quantum blockchains and post-quantum blockchains?

Post-quantum blockchains still run on classical computers but use quantum-resistant cryptography, while quantum blockchains directly integrate quantum networks and quantum cryptography.

Why is forward compatibility important for future blockchains?

Future quantum internet infrastructure may require blockchains to support quantum communication and quantum cryptography directly, so compatible architectures are needed early.
