- Considerations -The effectiveness depends on trust and participation throughout the supply chain. Only the information put on the blockchain is tracked, not necessarily the physical integrity of the goods.
Addressing Key Points From Ratings
- It's important to avoid making absolute claims about blockchain being an "ultimate security shield." Instead, emphasize its potential to enhance specific security areas, acknowledging its limitations and trade-offs.
- Provide concrete examples of blockchain-based solutions successfully addressing real-world security challenges, but don't overpromise or make unsubstantiated claims.
- Acknowledge the evolving nature of both blockchain technology and cybersecurity threats, requiring ongoing vigilance and adaptation of security strategies.
