BrandTrace : Brand Provenance on Blockchain

Problem:

• Fake products can be widely found in the market
• Untransparent supply chain
• Unable to prove the origin of the product
• Unable to trust proof and certificates from other countries
• USE CASE => brand traceability and anti-counterfeiting
• Outside of brand name => we can adapt the same system into a food and pharmaceutical provenance to avoid fake or uncertified items

Why Blockchain:

• When brand names are imported, the originality can be hard to track.
• Central authorities in a specific country might not be trusted by parties outside of the country.
• For instance, if you buy a Louis Vuitton bag from Paris, the bag will probably cost a fortune. This implies that customers will be more comfortable if they are provided with provenance from LV itself and these origin proof’s integrity should remain.
• Smart contract are globally trusted (if the system is fully open sourced and well-designed)

Installation (Front End)

Use the package manager npm to install dependencies in frontend.

Build and run

• Dockerfile => npm install && docker build -t brandtrace-frontend . && docker run -p 3000:3000 brandtrace-frontend
• npm => npm install && npm start
• yarn => yarn install && yarn start

Installation (Smart Contract)

Deployment

• Remix IDE => Copy contract to remix, compile, copy the abi to frontend.
• Truffle

Deploy on Truffle (localhost)

1. Install truffle (https://www.trufflesuite.com/docs/truffle/getting-started/installation) and ganache-cli (https://docs.nethereum.com/en/latest/ethereum-and-clients/ganache-cli/).
2. truffle compile
3. ganache-cli
4. truffle migrate
5. copy abi inside build/Producer.json and build/ProductManager.json and both addresses to frontend
