Japan Smart Chain Welcomes KDDI Corporation as a New Vision Partner

AltX Research K.K. is pleased to announce that KDDI Corporation has joined as a Vision Partner for its keystone project, “Japan Smart Chain” (JSC), a Japan-sovereign layer 1 blockchain.

JSC is the foundational, Japan-sovereign blockchain platform, featuring full compatibility with Ethereum and validated entirely by domestic industry leaders. It is engineered as a “compliance-first” Layer 1, embedding blacklist enforcement and transaction prioritization - making it a trusted infrastructure for regulated digital-asset services with regulatory integrity but without sacrificing usability.

Built on top of this foundation is Mizuhiki, a modular trust suite providing everything required to anchor verified identity, regulatory compliance, and risk management directly on-chain. Designed for flexibility across industries and use cases, businesses can launch and manage regulated digital services without relying on fragmented off-chain processes.

This partnership reflects both the growing expectation for JSC to become Japan’s largest homegrown blockchain platform—and KDDI Corporation’s strategic interest in expanding its validator business and exploring new synergies through the JSC ecosystem.

Moving forward, AltX Research and KDDI Corporation will continue to collaborate closely to explore concrete validator operations on JSC and to prepare for joint proof-of-concept trials for new domestic services leveraging the JSC ecosystem.
