IMO we need to break it in a few independent but cooperating decentralized systems;

1. A transportation service where consumers will request the transportation of goods or people from point A to point B, and providers will make bids for those requests.
2. A storage service where providers will offer storage of goods at specific locations, and consumers that make requests for the storage.
3. A LC service, where two parties can enter an letter-of-credit (LC) contract, and providers can guarantee the contract.

If these systems are available, it would be possible to implement additional decentralized services like;

• Marketplaces.
• Passenger transportation services.
• Food delivery.
• Probably many more.
