# Technical Architecture

The technical architecture of AITECH Cloud Network (ACN) is designed to support enterprise-grade scalability, flexibility, and interoperability across both infrastructure and execution environments. The system is built using a modular approach, ensuring that each component operates independently while remaining compatible within a broader integration framework.

This architecture enables ACN to support diverse use cases across compute access, workflow automation, and digital value exchange without introducing unnecessary coupling between systems.

***

#### **6.1 Modular System Design**

ACN follows a modular architecture where each functional component is isolated, allowing independent development, deployment, and scaling.

* Clear technical, functional and economic separation between infrastructure & execution.
* Components can be upgraded or replaced without affecting the entire system
* Reduced system complexity through defined boundaries
* Enterprise flexibility for integration into existing environments

| Module                 | Function                               | Design Benefit                |
| ---------------------- | -------------------------------------- | ----------------------------- |
| Compute Infrastructure | Executes high-performance workloads    | Scalable resource allocation  |
| Workflow Engine        | Manages execution logic and automation | Independent orchestration     |
| Payment Layer          | Handles transactions and settlement    | Unified economic coordination |

***

#### **6.2 Workflow Execution Model**

The workflow execution model defines how tasks are structured, triggered, and completed within Agent Forge.

* **Multi-step Execution**\
  Workflows are composed of sequential or conditional steps
* **Event-Driven Triggers**\
  Execution can be initiated by user input, scheduled triggers, or external events
* **State Management**\
  Each workflow maintains context across steps for continuity
* **Tool Interaction**\
  Workflows interact with APIs, data sources, and services during execution

| Component        | Role                                      |
| ---------------- | ----------------------------------------- |
| Trigger System   | Initiates workflow execution              |
| Execution Engine | Processes logic and task sequencing       |
| State Manager    | Maintains workflow context                |
| Output Handler   | Delivers results or triggers next actions |

***

#### **6.3 API and Integration Layer**

The integration layer enables connectivity between ACN products and external systems, ensuring compatibility with enterprise environments.

* Standardized API access for Agent Forge
* Support for third-party tools, data providers, and enterprise systems
* Ability to connect multiple services within a single workflow
* Designed for extensibility across different industries and use cases

| Integration Type    | Purpose                                   |
| ------------------- | ----------------------------------------- |
| External APIs       | Access data and services                  |
| Blockchain Networks | Enable on-chain interactions              |
| Enterprise Systems  | Connect internal tools and infrastructure |
| Data Providers      | Supply real-time and historical data      |

***

#### **6.4 Payment and Settlement Layer**

The payment and settlement layer enables seamless value exchange across the ecosystem using both on-chain and programmable payment mechanisms.

* Support for **on-chain transactions** using $ACN and stablecoins
* Integration of **x402 protocol** for agentic & request-based payments
* Enables workflows to request payment before execution
* Facilitates subscription models and usage-based billing

| Payment Mechanism   | Function                                |
| ------------------- | --------------------------------------- |
| $ACN Token          | Primary medium of exchange              |
| Stablecoins         | Alternative payment option              |
| x402 Protocol       | Agentic payment enablement              |
| On-Chain Settlement | Transparent and verifiable transactions |
| FIAT                | Top up FIAT (USD) using Stripe          |

***

#### **6.5 Interoperability Across Chains and Services**

ACN is designed to operate across multiple environments, ensuring compatibility with both blockchain networks and traditional systems.

* Cross-chain compatibility for payments and deployments
* Integration with EVM-based and other supported networks
* Ability to interact with off-chain services and infrastructure
* Supports hybrid workflows combining on-chain and off-chain execution

| Domain                    | Interoperability Capability                  |
| ------------------------- | -------------------------------------------- |
| Blockchain Networks       | Cross-chain payments and deployments         |
| Off-Chain Systems         | API-based integration with external services |
| Enterprise Infrastructure | Compatibility with existing tech stacks      |
