Successful First Transaction on Testnet… “Overturning the Myth that PQC is Slow with Technology” — Successfully Transitioned to Quantum-Resistant Mainnet While Maintaining Existing Structure

SymVerse Labs, a next-generation blockchain infrastructure company, announced that it has successfully processed the first transaction on its Quantum-Resistant testnet, marking the successful implementation of the world’s first native code-based “Dual Cryptography Blockchain Mainnet.”

In the case of Abelian, known as a representative PQC (Post-Quantum Cryptography) blockchain, its Proof of Work (PoW) method results in very slow block generation speeds, making it less effective for financial transactions or stablecoins. The recently introduced QDay is the world’s first quantum-resistant EVM-compatible layer, enabling Ethereum-based smart contracts to run in a quantum-secure environment; however, it has the limitation of being a Layer 2 solution.

Additionally, QRL (Quantum Resistant Ledger) is a native PQC blockchain that does not use EVM. However, due to the inconvenience of having to verify the usage count of encryption keys, it is considered more suitable for small-scale enterprise versions rather than blockchains requiring large-scale transactions.

In contrast, SymVerse Labs’ mainnet is designed with a Distributed ID-based structure. From the initial design stage approximately 8 years ago, it applied an extended structure that separates some bits of the 10-byte ID into a version area. This allows for the selective use of ID versions 0 and 1. In this testnet, this structure was expanded so that if an ID starts with 0x0, the existing mainnet operates, and if it starts with 0x4, the quantum-resistant mainnet operates.

This structure enables a gradual transition (Quantum Migration) to a quantum-resistant mainnet while maintaining compatibility with the existing account system. It is evaluated as a unique case that presents a practical solution to the “quantum transition problem” faced by existing blockchains while simultaneously providing real-world performance suitable for various sectors.

Meanwhile, Cardano founder Charles Hoskinson recently pointed out the structural limitations PQC imposes on blockchain performance in a public statement, noting, “Post-quantum cryptography generally makes blockchain processing speeds 10 times slower, increases proof sizes by 10 times, and lowers overall efficiency by more than 10 times.”

However, Dr. Hyuk-Jun Ko, Head of Development at SymVerse Labs, refuted this claim, stating:

“SymVerse achieved faster transaction processing speeds after applying PQC compared to the existing ECDSA-based structure. We also maintained the proof size without change by utilizing a HASH-based structure, and actually maximized overall system efficiency.”

In fact, the SymVerse Quantum-Resistant Testnet recorded over 3,000 transactions per second (TPS), which is evaluated as a case that technically overturns the conventional wisdom that PQC application leads to performance degradation.

The SymVerse Quantum-Resistant Blockchain is the world’s first full-stack PQC-Native blockchain operating on a Proof of Stake (PoS) basis. It applies National Institute of Standards and Technology (NIST) standard PQC algorithms to all layers, including accounts, signatures, communication, consensus, and transactions.

Based on these technical achievements — which simultaneously provide complete blocking of quantum attacks, data integrity for 10–30 years, and real-world performance suitable for next-generation Web3, financial, and public systems — SymVerse plans to officially upgrade the existing SymVerse Mainnet to the Quantum-Resistant Mainnet within the first half of next year.
