PQ-Ready Upgrades (Kyber/Dilithium)
The security of today’s blockchains is based on elliptic curve cryptography (ECC), which is vulnerable to quantum computers. Modulax is engineered for cryptographic agility, meaning its signature schemes and account abstraction can be upgraded to post-quantum (PQ) standards without breaking legacy state.
"Harvest Now, Decrypt Later is the real threat. Modulax is building for a future where quantum attacks are not hypothetical."
The Quantum Threat
Shor’s Algorithm can break ECDSA and elliptic curve cryptography once scalable quantum machines exist
Attackers can harvest encrypted data now and decrypt it in the future when quantum power is sufficient
Without PQ upgrades, long-term blockchain security is compromised
Modulax Approach
Modulax uses a two-phase strategy to integrate PQ cryptography:
Phase One
Launch with standard ECDSA for full EVM compatibility
Ensure smooth onboarding for wallets, dApps, and tooling
Phase Two
Introduce Kyber (encryption) and Dilithium (signatures)
Support PQ-ready account abstraction
Allow developers to choose PQ accounts without breaking legacy contracts
Kyber & Dilithium
Kyber
Post-quantum key encapsulation
Secures encrypted communication and potential PQ channels
Dilithium
Post-quantum digital signatures
Replaces ECDSA for signing transactions and consensus
"Kyber and Dilithium are part of the NIST-selected post-quantum cryptography suite, giving Modulax a foundation aligned with global standards."
Developer Notes
What developers need to know:
Existing contracts and accounts will remain valid under ECDSA
PQ accounts can coexist with standard ones through account abstraction
RPC and JSON interfaces will expose PQ signatures as optional extensions
Migration tools will allow users to upgrade their wallets gradually
Roadmap for PQ Integration
Test PQ signature schemes in isolated modules
Expose PQ transaction types in testnet environments
Gradually roll out PQ accounts to validators and key dApps
Enable a full switchover path when quantum threats become practical
Conclusion
Modulax is not just an EVM-compatible blockchain. It is a quantum-resistant ledger designed to survive the next era of cryptography. By adopting Kyber and Dilithium, Modulax ensures that its consensus, accounts, and data will remain secure in the face of quantum computing.
"Future-proofing is not optional. Modulax builds today with quantum tomorrow in mind."
