- Blockchain mainnet officially tested through KOLAS‑accredited institution
- Average block time 1 second, peak 5,205 TPS… world‑class performance recorded
- Following venture business certification, adds KISA commendation and KOICA ODA partnership to expand global technology footprint
Seoullabs Inc. (CEO Do‑hee Jang), a specialist in blockchain and fintech, announced that its independently developed blockchain mainnet has been officially validated for highest‑level performance by an internationally‑accredited testing institution. The test was conducted by KTR, a nationally recognized testing agency accredited under the Korea Laboratory Accreditation Scheme (KOLAS).
According to the KTR performance test results, Seoullabs’ mainnet achieved a write‑throughput of 5,205 transactions per second (TPS) and a read‑throughput of 9,269 TPS. In a demonstration test simulating approximately 100,000 concurrent transactions, the average block creation time measured under 1 second and average transaction latency recorded 0.651 seconds. These results place the technology among the top performance levels in global blockchain mainnets.
As a comparison, the current widely‑used Layer 1 blockchain mainnet Ethereum is known to operate around 15–30 TPS under real‐world conditions, and requires several minutes to achieve finality. Solana, despite reporting tens of thousands of TPS in stress tests, is known to run around 1,000 TPS in practical operation, with block finality of approximately 12.8 seconds. Bitcoin is even slower, estimated at about 7 TPS, making it less suitable for commercial service. By comparison, Seoullabs’ mainnet—achieving up to 5,000 TPS, block creation under 1 second, transaction latency of 0.651 seconds—demonstrates leading technology in both practicality and scalability.
Leveraging this mainnet technology, Seoullabs is also developing its proprietary solutions: a “Super Wallet” integrating AI‑based decentralized identity (DID), and a fiat‑pegged token issuance and circulation platform. These development efforts recently culminated in Venture Business Certification (Technology‑Innovation Growth Type) from Korea’s Ministry of SMEs and Startups.
Do‑hee Jang, CEO of Seoullabs, commented:
“This performance test is a meaningful milestone that objectively proves the practicality and global competitiveness of K‑blockchain technology. It shows that we have reached a level that meets the speed, reliability, and scalability required across public and financial sectors.”
In October, Seoullabs participated in the world’s largest fintech exhibition, Money20/20 USA, in Las Vegas. There, it held one‑on‑one partnering meetings with Circle, Fireblocks, and Uphold, discussing U.S. and Latin American market entry. It also hosted a briefing session with Nevada state government startup‑support officials, building strategic foundations for local market entry.
Additionally, Seoullabs was recently awarded a commendation by the Korea Internet & Security Agency (KISA) for its contributions to the blockchain industry, and was selected as a partner institution under KOICA’s ODA programme, underpinning the global expansion of K‑blockchain technology.
