Compact Shielded CSV: Post-Quantum, Private, Lightweight Client-Side Validation Blockchain

We propose Compact Shielded CSV, a private client-side validation blockchain for peer-to-peer payments designed for the postquantum era. Upgrading existing blockchains to quantum-resistant cryptography substantially increases on-chain overhead. By keeping all large cryptographic artifacts off-chain, Compact Shielded CS...

Position: Quantum Program Generation Must Prioritize Validity Over Probabilistic Scaling

This position paper argues that applying this probabilistic paradigm to generic quantum circuit synthesis is a directional error, and proposes a pivot from human-centric copilots to verifier-centric agents, and suggests that scale alone cannot bridge the validity gap.
