Amid concerns over the limitations of existing public-key cryptography due to advancements in quantum computing, Bitcoin and Ethereum are discussing gradual or hybrid transitions. In contrast, SymVerse has begun practical preparation by implementing “Dual Cryptography,” which natively supports both ECDSA and PQC at the mainnet level.

Warnings are mounting that the rapid development of quantum computing technology could threaten the security systems of existing blockchain networks in the long term. Quantum computers are evaluated as having the potential to theoretically neutralize ECDSA and RSA-based public-key cryptography — currently used as standards — through methods like Shor’s algorithm. Consequently, discussions on countermeasures are intensifying, centering on major public blockchains like Bitcoin and Ethereum.

While Bitcoin and Ethereum are reviewing gradual or hybrid transition plans while maintaining their existing structures, SymVerse is garnering attention as a realistic alternative for quantum-resistant blockchains through a mainnet that implements a native Dual Cryptography system supporting both ECDSA and PQC simultaneously.

Bitcoin (BTC) maintains an approach that prioritizes network stability and existing security philosophies, showing a cautious attitude toward adopting quantum-resistant cryptography. The direction most widely discussed currently is a hybrid method that runs existing ECDSA address systems alongside future PQC-based addresses; related proposals like BIP-360 are representative of this. This method has the advantage of enabling a gradual transition to a quantum-resistant signature system in the long term while maintaining past transaction history and network reliability. However, it is pointed out that this stage requires broad community consensus due to issues such as migrating hundreds of millions of existing wallets, the possibility of chain splits, and risks during the consensus process.

Ethereum (ETH) is showing a relatively more active stance on discussing the introduction of quantum-resistant cryptography based on its more flexible account and signature structures. Core developers, including Vitalik Buterin, have publicly mentioned the necessity of transitioning to PQC within a few years, and EIPs proposing structures that allow the network to recognize and use multiple signature algorithms simultaneously are under discussion. This approach is evaluated as a direction that seeks to enhance security without a network-wide hard fork by allowing account owners to select PQC signature methods. However, analysis suggests that since Ethereum’s core design is also deeply anchored in ECDSA-based account structures, a complete transition to quantum resistance entails technical difficulties as well as burdens in terms of governance and consensus.

While both Bitcoin and Ethereum remain in the stage of discussing gradual or transitional responses, SymVerse presents a differentiated strategy by already operating a native mainnet premised on quantum resistance. SymVerse has implemented a Dual Cryptography system supporting both ECDSA and PQC at the blockchain core level, taking an approach different from simply appending PQC to an existing system.

SymVerse’s Dual Cryptography structure is distinct from what is commonly referred to as “hybrid.” If the hybrid method is a transitional structure running existing and new address systems in parallel, SymVerse’s Dual Cryptography is designed so that both cryptographic systems branch directly within the execution path from the blockchain native code and are reflected simultaneously in the verification and consensus processes. This differentiates itself by being a structure where the blockchain itself adapts to changes in the security environment, rather than relying on a single cryptographic algorithm.

While other projects advocating quantum-resistant cryptography exist, most are evaluated as being limited to single PQC applications, remaining in experimental stages, or suffering from performance degradation issues. Considering these limitations, SymVerse is designed to minimize the processing speed reduction that generally occurs with PQC application while maintaining a processing performance of over 3,000 TPS and compatibility with existing blockchains. This is explained as a design result aimed at satisfying both quantum-resistant security and real-world usage performance.

Experts are noting the possibility that the Dual Cryptography structure could establish itself as a long-term standard architecture across the Web3 infrastructure. In particular, analyses suggest that for national and financial infrastructure domains requiring data integrity and security maintenance for at least 10 to 30 years — such as Central Bank Digital Currencies (CBDC), electronic signatures, financial messaging, and administrative records — a Dual Cryptography-based blockchain could be a more realistic option than a single cryptographic system.

Choi Soo-hyuk, CEO of SymVerse Labs, stated, “The Dual Cryptography system is not merely a technology using two cryptographic algorithms, but the very method by which a blockchain adapts to a changing security environment.” He added, “Web3 must move away from structures dependent on a single cryptography, and SymVerse Labs is presenting an infrastructure that has implemented this transition on an actual mainnet.”

SymVerse Labs is a company developing next-generation blockchain infrastructure capable of operating stably even in the quantum computing era. Through the world’s first Dual Cryptography mainnet and a full-stack PQC native structure, it aims to be a future-oriented blockchain possessing long-term security, scalability, and real-world performance.
