As I develop the Sustainable Supply Chain DApp, I face various challenges that require careful attention. Collecting reliable data from different supply chain actors is a complex task, as I need their cooperation and trust. Validating the data for accuracy is another challenge I must overcome, ensuring consistency throughout the supply chain.

Integrating the DApp with existing supply chain systems is not an easy feat due to different technologies and formats. Protecting sensitive data is of utmost importance to me, so I implement strong security measures and comply with privacy regulations like GDPR.

Encouraging participation from supply chain actors is a key focus for me. I communicate the benefits of the DApp, such as improved visibility and access to new markets. Scaling the DApp to handle increasing transactions and data is a challenge I tackle head-on, exploring innovative solutions to ensure efficiency.

Promoting awareness and educating stakeholders about sustainability is vital to the success of my DApp. I provide training and resources to help stakeholders understand the value of sustainable practices. Collaborating with experts and industry associations enhances my credibility and expands the reach of my educational efforts.
