System Architecture

1. Architecture Diagram

2. System Components

The Web Portal shows:

• data and visualization for Carbon Projects in the platform
• data from Carbon Project Directory and allows user to query it and obtain double counting risk score

The API Gateway dispatches API calls to API service of different Carbon Projects.

The Platform Management API provides platform management feature:

• Carbon Project creation
• User Management

Each Carbon Project will provision dedicated

• API service
• Blockchain
• Anomaly Detection Model for consistency check

This ensures project-level isolation, performance, and auditability.

The per-Carbon Project API service is responsible for

Data Tracing:

• data import and basic schema validation
• enforce tolerance checks according to PDD
• apply AI-based anomaly detection

Data Tracking:

• committing data to the blockchain
• call smart contract periodically to compute carbon footprint and reduction on blockchain

The Report Generator generate reports from the Carbon Footprint and Carbon Reduction records in the Blockchain.

The Carbon Project Directory contains data for Carbon Projects from different Carbon Registries. It also provides API for data query and computing double counting risk score.

2. Workflow

1. Upon onboarding a new Carbon Project, TCCTV Platform Operator will obtain from the Project Proponent

   • draft methodology and data schema for designing API service and Blockchain
   • historical data set for unsupervised training of Anomaly Detection Models

2. The Anomaly Detection Models will be trained, the API service and Blockchain will be implemented.
   Implementations can be reused if there are previously similar carbon projects.

3. The Project Proponent will continue to update the PDD The Carbon Project can enter the trial stage (with real or historical data) for the Carbon Registry to review the system

4. The Platform can then be used for DMRV after the Carbon Project is approved.
