Sign has created a full-stack CBDC solution for central banks, adopting a dual-layer architecture: Wholesale Layer and Retail Layer, which can be deployed separately or in combination.
Wholesale Layer: A high-performance privacy-protecting private blockchain is deployed within the central bank, with commercial banks connecting as authorized nodes. The core is the 'Central Bank Control Center,' achieving a unified, programmable, real-time approach to currency issuance, settlement, compliance, and policy execution, seamlessly integrating with existing RTGS systems to enhance transparency and controllability.
Retail Layer: Extends to payment service providers and end users. Commercial banks serve as the main interface, with Sign providing toolkits to assist in large-scale CBDC wallet deployment. Highlights include G2P tools (government funds directly reaching citizens' wallets, visible in real-time), a unified cross-bank CBDC wallet interface, and CBDC Bridge (supporting cross-border real-time settlement, connecting global liquidity pools like USDC, and interoperation with public chain digital assets).
Additionally, there are programmable modules (such as retail clearing integration, automatic deductions, Islamic finance modules, etc.).
The essence of Sign is: it does not disrupt the existing two-tier banking system, but rather reshapes the flow of currency through a programmable infrastructure, achieving a more transparent, efficient, and adaptable national digital currency system for the digital economy, laying the foundation for the next generation of finance. #sign地缘政治基建 @SignOfficial $SIGN
