Walmart's blockchain initiatives are a sign of the future of supply chain management

DL Freight blockchain: In 2019, Walmart Canada launched the DL Freight blockchain to automate the invoice payment process for its shippers. The blockchain system synchronizes all data points in real-time with each unique delivery, calculating information such as fuel costs, offroad distances, and delays at the point of delivery This has helped reduce payment disputes and improve efficiency.

Smart Contracts for Supplier Onboarding: Walmart is exploring how to use smart contracts to automate the supplier onboarding process. This will allow suppliers to get on board faster and more efficiently, and will also help reduce the risk of fraud.
