WIA Standard Overview

Discover the WIA-FIN-003 standard architecture: four progressive phases (Data Format, API, Protocol, Integration) that provide a complete roadmap from basic data structures to production cryptocurrency systems.

Standard Architecture 4-Phase Model Certification Levels

Phase 1: Data Format

Master the foundational data structures of cryptocurrency: transaction formats, block structures, address generation, and serialization. Learn how proper data modeling ensures security, efficiency, and interoperability.

Transactions Blocks Addresses Merkle Trees

Phase 2: API - Wallet & Exchange

Build standardized RESTful APIs for wallet operations and exchange trading. Implement authentication, rate limiting, WebSocket streams, and multi-exchange aggregation for seamless cryptocurrency interactions.

Wallet API Exchange API Authentication WebSockets

Phase 3: Protocol - Consensus & P2P

Dive deep into consensus mechanisms (Proof of Work, Proof of Stake, DPoS) and peer-to-peer networking. Understand how distributed nodes achieve agreement, maintain security, and propagate transactions across the network.

Proof of Work Proof of Stake P2P Networking Propagation

Phase 4: Integration - Exchanges & Custody

Integrate cryptocurrency with real-world systems: centralized/decentralized exchanges, institutional custody (MPC, HSMs), payment gateways, and regulatory compliance (KYC/AML). Bridge crypto and traditional finance.

CEX/DEX MPC Custody Payments Compliance
