  • Objective: To compare the performance, scalability, and energy consumption of blockchain and Directed Acyclic Graph (DAG) for securing legal evidence in the context of consumer rights enforcement.

    Research Focus:

    • Analyze and benchmark the scalability and energy consumption of both blockchain and DAG in the context of storing digital legal evidence.
    • Investigate the trade-offs between security, decentralization, and efficiency in both systems.

    Key Deliverables:

    • A detailed performance comparison of blockchain and DAG in terms of speed, scalability, and energy usage.
    • Recommendations for which technology is better suited for legal evidence storage, based on different criteria (e.g., energy efficiency, data volume).
