Sawtooth Marketplace

Sawtooth Marketplace is a blockchain application built on Hyperledger Sawtooth, allowing users to exchange quantities of customized "Assets" with other users on the blockchain. This repo contains a number of components which together with a Hyperledger Sawtooth validator, will run a Sawtooth blockchain and provide a simple RESTful API to interact with it. The components in this repo include:

  • a rest api which provides HTTP/JSON endpoints for querying blockchain data
  • a transaction processor which handles Marketplace transaction logic
  • a ledger sync which writes blockchain state changes to a local database
  • SawbuckManager and an example client which uses Marketplace to create a loyalty point program that users can interact with through a simple web app
  • a shell with all of the dependencies necessary to run support scripts


This project utilizes Docker to simplify dependencies and deployment. After cloning this repo, follow the instructions specific to your OS to install and run whatever components are required to run docker and docker-compose from your command line. This is only dependency required to run Marketplace components.

Before startup, the REST API requires a configuration file to be created at rest_api/ with sensitive security information and other settings. An example file is provided to illustrate what settings are available and how they should be used. To get started, you could simply copy this file into the appropriate location. Using bash from the root project directory, that would look like this:

cp rest_api/ rest_api/

Note that while this is fine for development purposes, the example secret keys provided are not secure. These settings in particular should be changed before deployment.

Now with your config file in place, Docker can take care of the rest. From the root project directory, simply run:

docker-compose up

This will take awhile the first time it runs, but when complete will be running all required components in separate containers. Many of the components will be available through HTTP endpoints, including:

The Admin CLI

In addition to simply running the components, you will likely want to use the mktadm CLI, which provides commands for interacting with SawbuckManager, like seeding initial data, or scheduling daily deals. This is simple using the provided shell container. Open a new terminal and run:

docker exec -it market-shell bash

This will open a bash terminal within the shell container, with the bin/ directory in the PATH, and all dependencies installed. Now to seed SawbuckManager with all the needed Offers and Assets run:

mktadm seed --url market-rest-api:8000 --data sawbuck_app/app_data.yaml

And if you would like to schedule daily deals using cron, run:

mktadm schedule --daily "renew --url market-rest-api:8000 --data sawbuck_app/app_data.yaml"

Note that you must leave this container running for it to submit new deals each day. If you just want to exit the shell (this will not stop the container), you can simply run:



The default Docker containers use the volumes command to link directly to the source code on your local machine. As a result any changes you make will immediately be reflected in the Marketplace components without having to rebuild them. However, typically you will have to restart a component before it can take advantage of any changes. This can be done from separate terminal than the one running your docker containers, using docker and the container name. For example:

docker container restart market-rest-api

The available container names include:

  • market-shell
  • market-processor
  • market-rest-api
  • market-ledger-sync
  • market-sawbuck-app
  • rethink-db
  • sawtooth-shell
  • sawtooth-rest-api
  • sawtooth-settings-tp
  • sawtooth-validator

You can also shutdown every container from the terminal running your containers. In bash this is typically done by pressing the key combination: ctrl-C. Once shutdown is complete you can restart them (without rebuilding them), by re-running docker compose up:

docker-compose up

If you want to rebuild the containers (but not the images), before running up, run down first:

docker-compose down

This will destroy the containers, including any app data that has been saved, and build them fresh from the original images. This will allow you to start with a clean slate, but do not run down if you wish to retain your app data.

Static Client Files and Protobufs

In addition to the above commands, some source code is used to generate run-time code, and this run-time code will have to be re-generated for changes to be reflected. The happens automatically anytime you run up, but this can be time consuming if you are rapidly iterating on the code. Dev scripts are provided to to quickly do this code generation in a temporary docker container (note that these commands require bash).

To generate Protobuf files:

bin/dev-tools -p

To generate static client files:

bin/dev-tools -c

You can also run these scripts directly using the same market-shell container used to run mktadm above. This can be useful if you are on a Windows machine without access to a bash terminal, or simply want to save yourself the 5-10 seconds required to build and tear down a temporary docker container. First, if you haven't already, exec into the shell:

docker exec -it market-shell bash

Then run the command to generate Protobuf files:


Or the command to generate static client files:

cd sawbuck_app/
npm run build

Note that the static server running SawbuckManager serves the generated client files directly from your local machine on each page load. This means you only need to generate the files and refresh your browser to see changes. You do not need to restart the SawbuckManager container.


Dockerfiles are also available to build images suitable for deployment, and are demarcated with a -installed tag. These will include the source code in the image itself, rather than referencing what is on your local machine at runtime. This may be useful if you wish to distribute self-contained docker images which do not need the source code to run. They can be built individually using the docker build command, or all built and run together using docker-compose:

docker-compose -f docker-compose-installed.yaml up

Remember that unlike the default Docker images, if the repo changes, those changes will not be reflected unless the images are rebuilt. To do that with docker-compose, use:

docker-compose -f docker-compose-installed.yaml up --build

Note that this compose file only exposes the URL for SawbuckManager and the Marketplace REST API, not Sawtooth or RethinkDB.


Docker based integration tests are available. They can be built and run in one command:


By default this command will run all tests in the integration_tests/ directory. It is also possible to run a single set of tests by specifying its sub-directory:

bin/market-integration-tests rest_api

You can also lint your Python code within a docker container using the dev-tools script:

bin/dev-tools -l
