What problems does VeChain solve?

Could you please elaborate on the issues that VeChain aims to tackle? I'm particularly interested in understanding how it addresses challenges in the realm of supply chain management and product authenticity. Could you also discuss its potential impact on enhancing transparency and trust within these systems? Additionally, how does VeChain's blockchain technology contribute to solving these problems, and what are some of the unique features or advantages it offers compared to other solutions? I'm keen to gain a deeper understanding of VeChain's role in addressing these challenges.
