The Grand Challenge of PQC Migration: Analysis of Modern Blockchain and Intertwined Human Egoisms

본문 미리보기

Since the invention of Bitcoin in 2008, blockchain technology has evolved from a simple decentralized ledger into a complex, multi-functional financial system spanning multiple layers. Despite this evolution, the cryptographic primitives foundational to this trustless system are now threatened by the emergence of quantum computers. While the necessity of Post-Quantum Cryptography (PQC) migration is widely acknowledged, blockchain remains an extremely challenging domain for cryptographic migratio
