TEMCO is developing a supply chain data platform on the Bitcoin network using RSK's smart contract. For businesses, TEMCO offers a business intelligence tool to analyze and visualize aggregated supply chain data on blockchain. For consumers, TEMCO offers a consumer application where they can check product and supply chain information about their purchases. In addition, a market plaform is offered to directly connect proven vendors to final consumers.TEMCO is envisioned as a public supply chain blockchain system that aims to utilize Smart Contracts to overcome the limitations of existing supply chain management systems. In the existing system, the information of each distribution participant within the supply chain process may be segregated and cut off from the each other, but TEMCO aims to make it possible to connect each participant through a blockchain so that the pre-delivery stages can be grasped in real time. The potential is to build consumer trust regarding the supply chain process, and also to create a cost-cutting effect through more efficient supply chain management.
