Compact Shielded Client-Side Validation Solves Quantum-Resistant Blockchain Issues
Compact Shielded Client-Side Validation (CSV) is a new architectural paradigm that addresses the network congestion, high gas fees, and state bloat caused by the transition to post-quantum cryptography. Developed by Dragos Ilie and a team from Imperial College London, CSV removes signatures from the blockchain and shifts data storage and verification to end-user devices, promising an on-chain footprint far lighter than even today's legacy blockchains.
