Korea Advanced Materials Announces Early Lead in 'Quantum-Secure Blockchain L2 Network'

Korea Advanced Materials, a KOSDAQ-listed company, is introducing "QuantumShield L2," an Ethereum-compatible Layer 2 (L2) network that applies quantum-resistant cryptography. On April 15, the company announced that with the release of this network, it is officially entering the race for next-generation blockchain security infrastructure.

Recently, Vitalik Buterin, co-founder of Ethereum, remarked that quantum computers could threaten existing cryptographic systems as early as around 2028. As a result, the need for quantum security is rapidly gaining prominence across the industry. In Korea, discussions on the Digital Asset Basic Act and movements toward institutionalizing a won-based stablecoin are further intensifying the demand for advanced security technologies.

In this context, Korea Advanced Materials has set a strategy to secure an early lead in the market with its L2 network based on quantum-resistant cryptography. QuantumShield L2 maintains compatibility with existing Ethereum networks while offering higher transaction speeds and reduced costs. Various existing services such as DeFi, NFTs, and gaming can also be migrated without the need for additional code modifications.

Notably, the platform incorporates ML-DSA, the quantum-resistant cryptography standard from the U.S. National Institute of Standards and Technology (NIST), and introduces a dual security structure by operating in parallel with the current electronic signature method. This design aims to protect against both present hacking threats and future attacks using quantum computers.

The company stated, "Going forward, the benchmark for blockchain competitiveness will shift from speed to security," adding, "In an environment where institutional capital is entering, networks equipped with quantum security infrastructure are likely to take the lead."

Technology to address performance degradation has also been implemented. By introducing a "Session Key" system, where only the initial authentication is performed robustly and subsequent transactions are processed lightly, the company explains it has achieved both security and efficiency.

In addition, the network supports account abstraction and smart contract wallet features, enabling users of existing Ethereum wallets such as MetaMask to transition to a quantum-resistant signature environment without complex procedures. The company is also being recognized for its competitiveness in user convenience and scalability.

Furthermore, Korea Advanced Materials is collaborating with global blockchain security firm CertiK to verify the network’s stability and security. The company emphasized that the environment has been implemented for real asset transfers, not just in a simple test phase.

Looking ahead, the company plans to build an ecosystem encompassing stablecoins, institutional funds, and digital financial infrastructure based on the QuantumShield network. Korea Advanced Materials aims to continuously expand its market influence by forging additional partnerships and broadening its services.

A representative from Korea Advanced Materials stated, "This project will serve as a turning point for the blockchain industry, shifting the competition from technology-centered to security infrastructure-centered," adding, "Ultimately, the digital asset market will be restructured into a framework where 'security is value.'"
