摘要

Blockchain technology has significantly transformed various industries by enabling secure and tamper-resistant transactions. However, the rise of quantum computing threatens the cryptographic foundations of blockchain networks, making blockchain vulnerable to signature forgery and transaction manipulation. This raises concerns about the long-term viability of blockchain systems and highlights the need for post-quantum secure solutions. This paper investigates the feasibility of quantum-resistant blockchain ecosystems. Our research focuses on estimating the cost of the integration of the post-quantum algorithms selected in the NIST standardization competition into Ethereum-based blockchains.
