Background  Information on Eximchain:

 

Utility Infrastructure for Enterprise Supply Chain Applications

Eximchain brings visibility to global supply chain finance (SCF) through smart contracts. They are building a public, permissioned chain for small-and-medium enterprise (SME) buyers and suppliers to create supply chain optimization tools and gain access to affordable capital sources to grow their businesses. Their smart contract-based ecosystem allows SMEs to quickly implement customized SCF solutions or issue digital tokens on a permissioned fork of Ethereum supporting data privacy. Eximchain adopts a consensus protocol and quadratic voting based governance model to provide practical, finite time security guarantees on their public, permissioned blockchain hybrid. From financing to procure-to-pay, their products utilize smart contracts to optimize the global supply chain for buyers, suppliers, and financiers. Eximchain is an official candidate of the Blockchain Regulatory Sandbox Program in Guiyang, China and a member of EEA (Enterprise Ethereum Alliance).

About the EXC Token

EXC tokens are ERC-20 compatible, and their purpose is to generate a valid ledger to seed the genesis file of our Eximchain mainnet. The ERC-20 tokens will be distributed on the Ethereum blockchain pursuant to a related ERC-20 smart contract. They are redeemable for Native Tokens on the Eximchain Platform upon network launch.

Following the Eximchain Mainnet Network Launch in Q2 2018, Eximchain’s Native Tokens will be used to pay network fees, validate state changes, and execute governance. The Native Tokens will also be used to access applications built on the Eximchain network, such as Smart Contracts and solutions developed with the Eximchain SDK.

 

Presentation for my Master’s Program

I’m taking my Supply Chain course in my Masters Program and as a part of the course we are required to have an end-of-semester project. For my project, I proposed to my professor that I’d perform an Eximchain review, which is a project I’m very excited about. The professor agreed to my proposal.

In an attempt to step it up a notch, I decided to try and interview the CEO, Hope, and in return I’d record the presentation and upload it to YouTube. Unfortunately, Hope was unable to respond to my questions in time for the presentation (Understandable as she’s a busy woman), but the admin team on their telegram chat were more than happy to answer any questions I had.

*I’ll just have a quick write-up here on Eximchain. You can also see my full report attached below for your reference if you’d like to read more into the project.

Eximchain focuses on merging the Global Supply Chain with blockchain technology. The main focus of the project is Supply Chain Financing (SCF). Whenever we mentioned this during the presentation, the professor got even more interested. We go into details of what Eximchain is offering in the presentation as well as in the Paper we wrote.

Q&A

Before I leave you with the video presentation, allow me to add the Q&A session I had with Eximchain. Unfortunately, this part of the presentation is not included in the video.

Q.1: Based on the example you provided on your whitepaper regarding the credit rate arbitration between the supplier and the buyer. Is the data involved (such as how much the supplier would save) private or shared with the buyer? If it is shared, wouldn’t the supplier be wary of such sensitive information being made visible?

A1: Up to the parties involved, this is the point of private smart contracts, you are right this is not possible in vanilla ethereum as the data would be public to all

Q.2: Should the information not be visible, does the Eximchain platform decide on the best terms for all the parties involved?

A2: Each party to a private contract specifies who participates in the Diffie Hellman key exchange for the private transaction payload, so the writer of smart contract decides.

Q.3: The Proof of Existence can be used to verify that Party A delivered goods, and Party B paid money. Is there a way to verify the quality of goods delivered by Party A (such as Reputation Protocol)?

A3: Yup this is actually the PoC being worked on in China (proof of quality)

I believe there are at least 5 other proofs throughout the process being designed as well: Proof of Order, proof of quality, proof of shipment, proof of payment, proof of credit

Q.4: Once a developer develops a certain solution to suit their own specific industry needs, would such a solution be publicly available or would the developer have complete right of ownership?

A4: Depends on how it’s deployed, if public contract then everyone can see, and access depending on smart contract logic, if private then the code can remain private only those that deploy and interact will be able to see.

In both cases the developer has full control.

I should note this is exactly the plan and would encourage you to reach out to team for early Dev program if you plan on doing so

Q.5  In your opinion, what is the most important (or influential) solution that Eximchain provides?

A5:  In my opinion, the automated infrastructure they are building is way ahead of what even the big players are doing

Video Presentation

At this point, I think the best way to present our work is through the video presentation. Unfortunately, the camera stopped recording after 20 minutes, which means the last few minutes of the presentation were missed as well as the professor’s comments. The professor was VERY excited about the project and about the size of the issue they’re tackling. He emphasized on the size of the problem and that there are trillions to make in this industry. Below is the video presentation.

 

If you want to go into even further details of our work, you can find the Project Report below for your reference. It took us a lot of time and effort to get this done so please make sure to give us credit in case you use this in any other place.
