Auditability

Midaz ensures data integrity and transparency through comprehensive auditing mechanisms that track every system interaction, supporting compliance and operational trust.

Auditing is foundational to Midaz’s promise of delivering robust, reliable, and transparent solutions for the financial sector. This mechanism ensures data integrity, fosters trust, and empowers Organizations to meet stringent compliance and security requirements.


Why Auditability Matter


Auditability ensures every action and change within the system is tracked and recorded. Auditability helps us:

  • Maintain the integrity of data across all touchpoints.
  • Enable effective audits, fostering trust among stakeholders.
  • Enhance transparency, reducing risks of fraud and operational inefficiencies.
  • Strengthen compliance with regulatory frameworks.

By embedding this mechanism into the Midaz system, Lerian delivers a solution that aligns with the highest standards of reliability, transparency, and verifiability.


Auditing Mechanisms


Midaz provides comprehensive auditing tools that ensure every action and change within the system is tracked and recorded. These tools support:

  • Transparency: Every system interaction—from data updates to transaction processing—is logged, creating an unalterable record.
  • Compliance: Detailed audit trails meet regulatory requirements, facilitating smoother audits and reporting processes.
  • Problem Resolution: Audit logs offer insights into system activity, aiding in debugging and fraud detection.

Features of Midaz’s Audit Logs

  • Granular Details: Logs capture essential metadata, including timestamps, user actions, and changes.
  • Append-Only Architecture: Audit logs themselves are immutable, ensuring historical records remain secure.
  • Flexible Access: Authorized users can access audit logs via intuitive APIs or the Midaz administrative interface.

Lerian's Approach to Auditability


For the Midaz system, achieving unparalleled auditability required exploring state-of-the-art solutions to ensure immutable storage and accessibility of financial transactions. After rigorous analysis, two industry-leading open-source technologies were evaluated:


Google Trillian

Google Trillian is an auditable log system leveraging Merkle Tree technology. As the backbone of Certificate Transparency—a global ledger for internet certificates—Trillian is built to thrive in distributed, scalable environments.

Lerian’s choice to implement Google Trillian was driven by its scalability, transparency, and adaptability to diverse operational needs. By utilizing MariaDB for storage, Trillian aligns seamlessly with Midaz’s architecture, offering enhanced visibility and flexibility without compromising on performance.

Advantages:

  • Backed by Google’s reliability and active maintenance.
  • Proven scalability and robustness in distributed systems.
  • Flexibility for custom audit tool implementation.

Challenges:

  • Limited community documentation.
  • Initial implementation complexity.
  • Requires internal development of auditing tools.

Implementation Blueprint

To integrate Google Trillian into the Midaz system, the following development requirements were established:

  1. All transactions will be asynchronously logged into Trillian via RabbitMQ queues.
  2. Each ledger will have a dedicated Merkle Tree, ensuring granular control and traceability.
  3. The solution will provide configurability, allowing users to enable or disable Trillian usage through parameters.

This architecture underscores our commitment to delivering a customizable, future-proof solution that caters to diverse operational needs while maintaining Lerian’s standards of excellence.
