📕 **ISO/DIS XXXX:2025 RWA 3-Grid Ecosystem — Architecture, Terminology and Functional Requirements** Draft International Standard (DIS) v0.9 Proposed by: Dadam Electronics Co., Ltd. (Republic of Korea) (World-first proposer of the 3-Grid Model for RWA Infrastructure) Foreword The rise of Real-World Asset (RWA) tokenization is establishing a new global paradigm for value exchange across finance, manufacturing, trade, digital identity, and sovereign data systems. Current RWA markets lack unified architecture for verification, legal enforceability, cross-border interoperability, and lifecycle integrity. The “RWA 3-Grid Ecosystem Standard” introduces a harmonized, multi-layered structure designed to ensure authenticity, trust, modular scalability, and international interoperability. This Draft International Standard has been proposed by Dadam Electronics Co., Ltd., based in the Republic of Korea, as the first structured RWA grid architecture intended for global adoption. Introduction RWA tokenization depends on the integrity of both physical assets and their digital representations. However, global markets operate without: Trusted 1:1 physical-digital authentication Unified verification procedures Legally enforceable digital-asset contracts Modularized infrastructure for multi-industry deployment Cross-border compliance between RWA, CBDC, and ISO20022 messaging The RWA 3-Grid Ecosystem resolves these challenges by providing a three-layer grid architecture (Grid 1–3) that ensures interoperability, verifiability, and regulatory alignment. 1 Scope This document specifies the architecture, terminology, functional requirements, and interoperability specifications for the global RWA 3-Grid Ecosystem Standard. It defines: Required components of Grid 1, Grid 2, Grid 3 Verification and authentication procedures Messaging alignment with ISO20022 and CBDC networks Security, compliance, and conformance requirements Interoperability rules between sovereign and institutional systems This standard applies to: RWA issuers Financial institutions Governments & regulators CBDC / tokenized asset networks Distributed ledger platforms Corporations performing asset lifecycle management 2 Normative References ISO 20022 — Financial Services Messaging ISO/IEC 27001 — Information Security Management ISO/IEC 20243 — Supply Chain Security ISO 17442 — Legal Entity Identifier (LEI) W3C DID Core Specification NIST SP 800-63 — Digital Identity Guidelines 3 Terms and Definitions 3.1 Real-World Asset (RWA) A physical or legally recognized asset whose properties are verified and digitally represented. 3.2 Digital Twin A verifiable digital representation of a real-world asset, linked through authentication procedures. 3.3 Grid 1 — Contractual & Smart Legal Layer The layer enabling legally enforceable digital agreements and rights. 3.4 Grid 2 — Physical-Digital Authentication Layer (PADT-RWA) Layer ensuring 1:1 asset–data binding, fraud prevention, and multi-factor verification. 3.5 Grid 3 — Modular Infrastructure Layer (RWA-MODULE) Layer enabling infrastructure deployment, lifecycle management, and multi-industry integration. 4 Symbols and Abbreviated Terms RWA — Real-World Asset PADT — Physical Asset Digital Twin DT-Auth — Digital Twin Authentication CBDC — Central Bank Digital Currency LEI — Legal Entity Identifier 5 System Overview The RWA ecosystem must guarantee: Asset authenticity Contractual validity Verifiable lifecycle records Interoperability across jurisdictions The 3-Grid Structure: Grid 1 → Legal trust Grid 2 → Authenticity trust Grid 3 → Operational trust These three trust layers operate cohesively to form a unified global RWA standard. 6 Architecture of the RWA 3-Grid Ecosystem 6.1 Grid 1 — Veritaseum Layer (Smart Legal Agreements) Ensures: Legal enforceability of digital agreements Automated execution of rights, claims, and settlements Regulatory alignment for cross-border financial operations 6.2 Grid 2 — PADT-RWA Layer (Physical–Digital Authentication) Provides: 1:1 Digital Twin identity binding Multi-factor, multi-sensor verification (e.g., NFC, certification, registry) Anti-counterfeit, anti-tamper assurance Government-grade auditability 6.3 Grid 3 — RWA-MODULE Layer (Modular Infra & Lifecycle) Includes: Issuance, transfer, settlement, redemption modules Supply-chain and logistic integration Cross-network interoperability modules Multi-industry vertical extensions (real estate, trade, commodities, IP assets, metals, luxury goods, etc.) 7 Functional Requirements 7.1 Asset Verification Functions Real-world condition verification Digital identity certification Event-driven lifecycle tracking 7.2 Cross-Border Interoperability Functions ISO20022 messaging compliance CBDC & DLT interoperability bridges 7.3 Security Requirements End-to-end tamper prevention Cryptographic identity protection Real-time authenticity monitoring 8 Interoperability Requirements The ecosystem must: Support national-level certification infrastructures Enable multi-ledger and multi-network interoperability Allow cross-jurisdiction legal compliance Operate across sovereign CBDC networks 9 Security Considerations Hardware-based asset verification (e.g., NFC, physical seals) Transaction-level anomaly detection AI-driven fraud prevention Immutable audit trails 10 Conformance & Compliance To be compliant with the RWA 3-Grid Standard, systems MUST: Implement all three Grid layers Maintain verifiable chain-of-custody records Provide regulatory-grade auditability Support cross-platform digital identity standards Annex A (Informative): Reference Diagrams Grid interaction diagrams (3-Grid triangular model) Annex B: Example Implementation CBDC–RWA integrated settlement model Annex C: National Certification Framework Example “K-Certification for RWA Authentication”
