Proofchain leverages blockchain technology to facilitate efficient communication and data exchange between global supply chains, providing customers with proof of product provenance and ownership.
Platform • Core features • Project Structure • Resources • Contributing • License
Smart Contracts: At the core of Proofchain are the smart contracts, written in Solidity, which live on the Ethereum blockchain. These make up an open platform that anyone can interact with.
Proofchain Dashboard: It offers a snapshot of the core features of the smart contracts based platform.
Proofchain Web3 library: A JS library which simplifies interacting with Proofchain contracts, facilitating communication between existing Supply Chain Management software and distributed ledged technology.
Proofchain Client App: A mobile-first web application that provides end users with the ability to view the complete provenance history of each product.
Representing physical goods in the form of non-fungible digital tokens and recipes that enable their transformation
In order to digitally represent a manufacturing process, tokens can be minted, added to a batch, or transformed into a new token based on a pre defined recipe.
Each batch of materials corresponds to one token that holds unique features. Batches can be transferred or used as input for other materials.
Batches can be transferred from one entity to another.
Supply chain entities and materials can be audited by third party "certificate authority" organizations. These certificates communicates impact about their business, proudcts and supply chains practices.
- Company identity: Each company that uses the Proofchain excosystem is identified by an ethereum address.
- Manufacturer company: Creates raw materials, materials, batches and transports.
- Transport company: Intermediary between other company types, can manage transports.
- Raw Materials
- Represented using non-fungible digital tokens that are created on a blockchain for each batch of manufactured products.
- Materials
- Similar to raw materials but are composed of multiple raw materials
- Batches
- Batches are a collection composed of the same material or raw material type
- Transports
- Property exchange mechanism. A transport is composed of the sender, receiver and transport company
- Certificates
- Certificates are a method by which companies communicates impact about their business, proudcts and supply chains practices.
- Certificate authorities:
- Certificate authorities can create and assign certificates to materials, raw materials and companies.
