What Sigma Chain does

Sigma Chain is a South Korea-based private blockchain technology company that develops and licenses a proprietary blockchain mainnet (Mainnet 4.0) powered by a patented 4th-generation DRPoS (Delegated Random Proof of Stake) consensus algorithm, which the company states has been verified by KOLAS at 300,000 transactions per second. Its product stack spans the full blockchain lifecycle: a high-speed mainnet, the NSTA-602 NFT standard protocol, NFP one-time-password authentication, DID/Decentralized Single Sign-On identity services, an STO (Security Token Offering) Exchange platform, and a DApp development framework (SADES) backed by ~150 pre-developed APIs (DAPI). The company also operates consumer-facing applications under the Piki Series brand (location-based AR SNS, NFT marketplace, local metaverse, chat).

The firm sells to enterprise and government-adjacent clients on a quote-based model, including Korea Hydro & Nuclear Power (QVD and CFSI verification), KAMP (manufacturing data and AI analytics portal, jointly with NHN and KoDATA), and Busan Cloud Cooperative Association, alongside 30+ strategic and technology partnerships across Korea and Southeast Asia. Revenue mechanics blend mainnet technology licensing, STO transaction and listing fees, DApp/NFP/DID subscription services, NFT marketplace commissions, and custom development; no public pricing or contract values are disclosed.

The company was founded circa 2014 and operates from Daegu, South Korea with a reported headcount of 1–10, a single disclosed funding round of $845,964 in 2019, and no parent company or institutional investor base beyond New Paradigm Investment. Distribution relies on direct enterprise sales and a formalized four-tier partner program (Regional/Channel, Service, Technology, DApp/SADES) with referral bonuses, supplemented by conference participation, a YouTube channel, and PR-driven content marketing. Notable enterprise indicators include selection for the Busan Blockchain Regulation Free Zone and an active Sandbox Korea Designation Application.
