1. Introduction

This document outlines the compliance requirements for the Gold Standard regarding the verification chain of custody for carbon credits. The purpose of this documentation is to ensure that DaedArch Corporation’s sensor-based Measurement, Reporting, and Verification (MRV) platform adheres to the stringent standards set forth by the Gold Standard. This includes the demonstration of Sustainable Development Goal (SDG) co-benefits, particularly in projects located in developing nations.

2. Chain of Custody

2.1 Overview

The chain of custody outlines the entire lifecycle of carbon credits from the point of measurement through to verification and eventual issuance. Each step in this process must be documented, ensuring that data integrity is maintained and that all stakeholders can trace the evolution of carbon credits.

2.3 Data Field Mappings

The following table outlines the required data fields for each step in the chain of custody:

| Step | Data Field Name | Data Type | Description | |--------------------------|--------------------------------|---------------|---------------------------------------------------| | IoT Sensor Measurement | sensor_id | String | Unique identifier for the sensor | | | measurement_value | Float | Environmental measurement value | | | measurement_unit | String | Unit of measurement (e.g., CO2e, kg) | | Data Processing | processed_data | JSON | JSON object containing processed data | | Verification Algorithm | verification_id | String | Unique identifier for the verification process | | | verification_status | String | Status of the verification (e.g., Passed, Failed) | | Verification Report | report_id | String | Unique identifier for the report | | | report_timestamp | Timestamp | Date and time of report generation | | Credit Issuance | credit_id | String | Unique identifier for the issued carbon credit | | | issuance_date | Timestamp | Date of credit issuance | | Stakeholder Consultation | consultation_id | String | Unique identifier for the consultation | | | feedback | String | Stakeholder feedback on the project |

3. Data Integrity

3.1 Data Capture

Data captured by sensors shall be transmitted in real-time to the DaedArch platform. The following specifications must be adhered to:

• Format: Data shall be transmitted in JSON format.
• Frequency: Sensors shall transmit data at intervals not exceeding 15 minutes.
• Validation: Each data packet shall include a checksum to ensure data integrity.

3.2 Data Storage

Data shall be stored in a secure, centralized database with the following specifications:

• Database Type: SQL or NoSQL database that supports ACID properties.
• Encryption: All stored data shall be encrypted using AES-256 encryption standards.
• Access Control: Access to the database shall be restricted to authorized personnel only.

3.3 Data Transmission

Data transmission between the IoT sensors and the DaedArch platform shall be secured using TLS 1.2 or higher. The following requirements shall be met:

• Endpoint: All data shall be sent to the following API endpoint:
• POST https://api.daedarch.com/v1/sensor/data
• Payload: The payload must contain the following fields:

`json { "sensor_id": "string", "measurement_value": "float", "measurement_unit": "string", "timestamp": "ISO 8601 format" } `

4. Timestamp Verification

4.1 Timestamp Generation

Timestamps shall be generated at the point of data capture and must adhere to the following requirements:

• Format: Timestamps shall be recorded in ISO 8601 format (YYYY-MM-DDTHH:mm:ssZ).
• Precision: Timestamps shall include milliseconds for enhanced accuracy.

4.2 Timestamp Synchronization

All sensors shall synchronize their clocks with a reliable time source (e.g., NTP servers) at least once every 24 hours. The following procedure shall be implemented:

1. Configure each sensor to query an NTP server for the current time.
2. Log the synchronization event in the audit trail.

5. Tamper Detection

5.1 Tamper Detection Mechanisms

The platform shall implement the following mechanisms to detect tampering:

• Checksum Validation: Each data packet shall include a checksum that is validated upon receipt.
• Anomaly Detection: Algorithms shall analyze data trends and flag anomalies that exceed predefined thresholds.

5.2 Response Procedures

In the event of detected tampering, the following response procedures shall be enacted:

1. Immediate notification to system administrators via email and SMS.
2. Log the incident in the audit trail with details of the tampering attempt.

6. Audit Log Format

6.1 Log Structure

Audit logs shall be structured as follows:

| Field Name | Data Type | Description | |--------------------------|---------------|---------------------------------------------------| | log_id | String | Unique identifier for the log entry | | timestamp | Timestamp | Date and time of the log entry | | action | String | Description of the action taken | | user_id | String | Identifier of the user who performed the action | | details | String | Additional details regarding the action |

6.2 Log Retention

Audit logs shall be retained for a minimum of 7 years from the date of the last entry. Logs shall be stored in a secure, immutable format to prevent unauthorized alterations.

7. Compliance Assessment Procedures

7.1 Audit Procedures

The following audit procedures shall be conducted to ensure compliance with Gold Standard requirements:

1. Internal Audits: Conduct quarterly internal audits to review adherence to the outlined processes.
2. External Audits: Engage an independent third-party auditor bi-annually to assess compliance with Gold Standard requirements.

7.2 Reporting Requirements

Audit findings shall be documented in a formal report, including:

• Summary of findings
• Non-compliance issues identified
• Recommendations for corrective actions
• A timeline for implementing corrective actions

8. Conclusion

This document outlines the comprehensive requirements for the verification chain of custody as mandated by the Gold Standard. Adherence to these requirements is critical in ensuring the integrity and credibility of carbon credits generated through DaedArch Corporation’s MRV platform. Compliance with this documentation shall be subject to regular audits and reviews to maintain the highest standards of accountability and transparency in carbon market operations.
