Building a blockchain based transactional system

We want to build a blockchain-based transactional system, which lets user configures deals and specify the entities who will part take in the deal. It should also let the user configure a % of the funds or a fixed amount to each entity.

Each entity should be able to mark his or her part complete once the task assigned has been completed. The payment is only transferred once the tracked transaction is completed. It's a simple blockchain-based supply chain management logistics application.

When the deal is confirmed, the amount should be deposited into a safe deposit, which will keep it till the deal is either canceled or completed. Once completed, each entity gets the amount which was allocated to them.

The product is still evolving. User flows and architecture is still being ironed out but will be provided before development starts to make sure the developer has complete knowledge of the story we are building.

The developer will have to work with our onsite leader for day to day tasks and progress.
