Increased efficiency and speed: Traditinal way of doing is always involve peperwork, it could misplace or alwasy chance of human error it even take take longer time process but with automating and streaming process with blockchaintransaction an be completed faster and more efficently.

Reduce cost: as a business platform, reducing the cost is very important, so this can be achieve by using blockchain because we dont need third need third parties or middlemen ( such as : paying money to the quality checker ) insted we just need to trust the data on blockchian, we can avoid documentation to complete trade because everyone will able to access to single , immutable version.
