The problem SCM Flow solves

Lack of transparency: Traditional supply chains are often opaque, with limited visibility into the movement of goods and funds creates a distributed ledger system that allows all participants in the supply chain to have access to the same information.
Counterfeiting and fraud: Traditional supply chains are vulnerable to counterfeiting and fraud, as it can be difficult to verify the authenticity of products and the identity of participants in the chain.
Supply chain financing: Traditional supply chain financing can be slow, costly, and opaque. Blockchain-based supply chain management systems enable faster, more secure financing by creating a transparent, tamper-evident record of transactions.
