Localtrail - Community-first transparency in the supply chain

Problem

The process of establishing a data trail of the food and dairy supply chain from farm > warehouse > market > retailer is very manual and incentivizes dishonest behavior. Also currently, users have no good way of trustlessly knowing if their food is coming from the place that retailers say it is.

Solution

We want to provide a community-first, transparent blockchain solution to track produce from farm to supply center to the end user. We will be building on the Hyperledger runtime engine and using Tieron’s Chainpoint Node API. We are using React Native, JavaScript and Hyperledger Composer native languages.

Users

Farmer, who grow the food, package it, and enter in data Warehouse employees, who scan, perform QA check and ship to market Market employees, who scan and perform QA check and sell to retailers Retailers, who scan and perform QA check, and serve food to end consumers End consumers, who view the data from the process

User Journey

Farmer enters Produce Item (string) Ex. “Swiss Chard” Type of Item (string) Ex. “Green” Quantity (int) Ex. 5 Quantity Metric (string) Ex. Pounds Farm Name (string) Ex. Satur Farms Farm Street (string) Ex. 3705 Alvahs Lane Harvest Date (int)

Farm ZIP (int) Ex. 11935 Farm is Field (bool) If FALSE: Field Name (string) Ex. Jackson West Field Field Zip (int) Ex. 11965

Farmer enters in package data (food item, quantity, type, etc.) Farmer scans one of many QR code stickers. Data from client app is tied to unique QR code ID. Farmer submits data to blockchain. Farmer ships package to Warehouse.

Warehouse employee scans code, reads data Warehouse employee conducts package QA Warehouse submits that package has passed QA to blockchain, ships package to Market

Market employee scans code, reads data Market employee conducts package QA Market employee submits that package has passed QA to blockchain, ships package to Retailer

Retailer employee scans code, reads data Retailer employee conducts package QA Retailer employee submits that package has passed QA to blockchain, prepares food

End Consumer uses app to scan code, can read data
