Demonstration of Blockchain Identity (DI) and Payment (SGP) Unveiled
Blockchain technology is being partially applied to Samsung Card

Samsung SDS is setting out in earnest to pioneer a new market by launching blockchain platforms and solutions.

On the 6th, Samsung SDS unveiled its enterprise blockchain platform Nexledger and blockchain identity (DI) and payment (SGP) services to the press at the Samsung SDS Tower in Jamsil.

Blockchain refers to a public ledger technology containing transaction records shared by the parties involved. By digitizing and trading all physical and virtual assets, it enables trading parties to automatically and instantly share execution results identically. Furthermore, it ensures reliability because all parties view the same blockchain ledger, and no one can arbitrarily alter its contents.

Nexledger, unveiled by Samsung SDS on this day, is an enterprise blockchain platform that utilizes open source to provide various services based on a currently verified blockchain foundation, while restricting participants through permissions. By integrating its biometric authentication solution, Nexsign, into Nexledger, the company showcased services that further enhance security and convenience.


Blockchain identity and payment services have enhanced security while implementing real-time high-volume transaction processing, smart contracts that automatically and securely execute transactions, and management monitoring—features that were difficult to achieve with existing blockchain technology. Mobile device users can conveniently use various financial services without a separate authentication process through a single identity verification.

Song Kwang-woo, Head of the Financial Consulting Team (Senior Vice President) at Samsung SDS, said, “As it became unnecessary to use accredited certificates last year, financial institutions are looking for new authentication methods. Consequently, blockchain is emerging,” adding that blockchain-based identification will gradually replace them.

Samsung SDS has already been conducting a project to introduce blockchain technology with Samsung Card since last October. It launched an electronic document original verification service last February and is currently applying a partner member authentication service utilizing blockchain IDs. In the future, it plans to pursue various new services, such as digital point swaps for integrated point transactions between partner companies.

Executive Director Song stated, “Blockchain technology is not being widely applied in our country due to a lack of understanding. By the second half of next year, verified application cases in specific sectors are expected to emerge. We are not only developing the technology but also creating application cases simultaneously,” adding, “We are seeking diverse applications beyond finance, such as in the order-based industry where contract structures are complex and require sharing, and in insurance.”

Samsung SDS Solution Business Division Head (President) Hong Won-pyo stated, “We will integrate advanced ICT technologies into Nexledger to expand beyond finance to other industries, while also focusing on creating new markets aligned with the Fourth Industrial Revolution.”
