Post-quantum blockchain development
Quantum computers break the elliptic-curve signatures that secure most chains today. I migrate networks and wallets to the NIST-selected post-quantum standards: CRYSTALS-Dilithium and SPHINCS+ for signatures, CRYSTALS-Kyber for key exchange. Both a full switch and a hybrid scheme are possible, where a classical and a post-quantum signature run side by side during migration. The work includes signature size and throughput analysis, consensus and mempool adjustments, and migrating wallets and SDKs to the new algorithms. Delivered: a Layer-1 with NIST post-quantum cryptography sustaining 75,000+ TPS, and a messenger with post-quantum encryption for messages and calls. Stack: Rust, Dilithium, Kyber, SPHINCS+, Go, Kotlin.
