Running Hyperledger Grid on Sawtooth
Hyperledger Grid supports Sawtooth as a backend distributed ledger. This document shows how to set up a Grid-on-Sawtooth environment that runs in a set of Docker containers.
The example Sawtooth docker-compose file creates a network with two nodes (alpha and beta) that can be used for demos or application development. This environment includes the Pike, Product, Location, and Schema smart contracts.
- Pike handles organization and identity permissions with the Sabre smart contract engine.
- Grid Product provides a way to share GS1-compatible product data (items that are transacted, traded, or referenced in a supply chain).
- Schema provides a reusable, standard approach to defining, storing, and consuming the product properties. Property definitions are collected into a Schema data type that defines all the possible properties for an item.
- Docker Engine
- Docker Compose
Set Up and Run Grid
- Clone the Hyperledger Grid repository (https://github.com/hyperledger/grid).
Navigate to the grid root directory and build the Grid Docker containers.
$ docker-compose -f examples/sawtooth/docker-compose.yaml build --pull
Start the Grid Docker containers.
$ docker-compose -f examples/sawtooth/docker-compose.yaml up
This docker-compose file creates a network with two nodes (alpha and beta) that includes the Pike, Schema, and Product smart contracts.
Once the Grid on Sawtooth environment is running, you can demonstrate Grid functionality with existing smart contracts, such as Pike organizations and Grid products. You can also upload new smart contracts.
Demonstrate Grid Smart Contract Functionality
You can use the Pike and Grid Product smart contracts to demonstrate Grid functionality by creating an organization and agent, defining a schema for the product properties, and creating a product.
Creating Organizations describes how to create an owning organization for Grid items (such as products), and set the permissions for an agent who is allowed to create and manage those items.
Creating Schemas explains how to define the format of properties for Grid items such as products.
Creating Products shows how to create, update, and delete products as the organization’s agent.
Smart Contract Deployment
- Uploading Smart Contracts explains how to upload and configure a new smart contract.
