The True Quantum Resistance Manifesto: Principles for PQC-Ready Blockchains

We are Cellframe, a full-fledged L0 blockchain infrastructure with implemented and operational post-quantum cryptography (PQC). Drawing from our experience, we establish the following principles of True Quantum Resilience for the entire industry.

I. PQC Implementation at the Infrastructure Level (L0), Not in Overlays

Quantum security implemented via L2 rollups or L1 address migration is an illusion of safety. If the base layer remains vulnerable to Shor's algorithm, all data passing through it remains at risk of compromise. True quantum resilience demands PQC implementation at the fundamental L0 infrastructure level. Only when consensus and block finality are secured from within can a network be considered fully protected.

II. Flexibility and Adaptability: Rapid Algorithm Replacement Mechanisms

Post-quantum cryptography is evolving rapidly. Algorithms considered secure today may be compromised tomorrow. Infrastructure must enable swift replacement and addition of new cryptographic algorithms without network downtime or hard forks. Such adaptability is the only guarantee of an agile response to emerging threats throughout a blockchain's lifecycle.

III. Scalability and Performance Under PQC Load

Post-quantum algorithms are objectively "heavier" than their classical counterparts. Signatures and keys grow by orders of magnitude, and transaction verification demands substantially more computational resources. A network must be optimized for high throughput through a multi-chain architecture. Sharding, parallel processing, and offloading services to independent networks are not optional features — they are mandatory for survival in the quantum era.

Conclusion

Cellframe is the living proof of these principles in action. We have built an L0 infrastructure ready for Q-day, and we urge the industry to follow our lead.
