Datachain Launches Initial Launch Partner Program for On-Chain Privacy Platform 'KuraPrivacy' with 10 Companies to Demonstrate Privacy Protection and Regulatory Compliance in Stablecoin Transactions

Datachain Inc. (hereinafter 'Datachain') announces the launch of the initial launch partner program for its enterprise-focused privacy platform 'KuraPrivacy' (formerly known as 'Datachain Privacy'). Ten companies—Goukeisha Angoya, Gaia Inc., GALLUSYS Inc., Green Monster Co., Ltd., Genkosha Inc., Speee Inc., Tradum Inc., Japan Blockchain Infrastructure Co., Ltd., Fracton Ventures Inc., and HODL1 Inc. (in alphabetical order)—will participate as partners, jointly advancing the development and verification of Web3 wallets and applications capable of privacy-preserving transfers using 'KuraPrivacy' alongside Datachain.

1. Background and Purpose

Stablecoins are expected to serve as next-generation financial infrastructure for corporate settlements and cross-border payments. However, the inherent transparency of blockchain, where counterparties, amounts, and asset holdings are publicly visible, poses a significant barrier to widespread enterprise adoption.

While privacy technologies have long attracted attention within the blockchain community, most solutions have focused on individual users. Few offer the comprehensive enterprise-grade requirements such as AML/CFT compliance, auditability, flexible key management, and recovery mechanisms for multi-user operations.

'KuraPrivacy' is a solution developed by Datachain since 2025 to reconcile enterprise requirements with strong privacy protection. The core platform has already passed functional testing in a test environment. The next critical phase involves refining wallet and payment application designs with a focus on UI/UX tailored for daily enterprise operations.

This program aims to co-develop practical solutions through collaboration with partner companies possessing deep expertise in blockchain, iterating through use case validation and feedback. Through this initiative, Datachain aims to establish a Japan- and Asia-originated standard for enterprise on-chain privacy solutions.

■ Product Name

Coinciding with the program's launch, 'Datachain Privacy' has officially been renamed 'KuraPrivacy (Kura Privacy)'.

'Kura' in 'KuraPrivacy' derives from the Japanese word 'Kura' (蔵), meaning 'storehouse'. Historically, merchants across Japan used kura—robust, isolated structures—to securely store valuables and documents, accessible only to trusted individuals. This strict management system, which protected value while limiting access, supported trustworthy commercial transactions. The ethos of the kura aligns closely with KuraPrivacy's vision for on-chain privacy, hence the name.

■ About KuraPrivacy

KuraPrivacy is an on-chain privacy infrastructure that enables uncompromising privacy protection while maintaining high operational feasibility for enterprise use.
