Overview

To get from zero to a running consortium network through the Chainstack API, do the following:

1

Get your API key.

2

Export your API variables.

3

Create a project.

4

Create a network.

5

Add a node to the network.

6

Get the node access and credentials.

​
Step-by-step

​
Get your API key

See Create an API key.

​
Export your API variables

To save time when interacting with the API, export your API variables:

export APIURL="https://api.chainstack.com/v1"

export APIKEY="YOUR_CHAINSTACK_API_KEY"

export HDR_AUTH="Authorization: Bearer $APIKEY"

export HDR_CT="Content-Type: application/json"

​
Create a project

curl -X POST "$APIURL/projects/" --header "$HDR_AUTH" --header "$HDR_CT" --data '{"name":"YOUR_PROJECT_NAME","description":"YOUR_PROJECT_DESCRIPTION"}'

See also API reference: Create Project.

​
Create a network

You create a network with one peer node and service nodes.

The service nodes are created automatically with no input from you.

You must provide the node details for your peer node.

curl -X POST "$APIURL/networks/" --header "$HDR_AUTH" --header "$HDR_CT" --data '{"name":"NETWORK_NAME","project":"PROJECT_ID","protocol":"PROTOCOL","configuration":{"consensus":"CONSENSUS"},"nodes":[{"name":"NODE_NAME","type":"NODE_TYPE","role":"NODE_ROLE","provider":"CLOUD_PROVIDER","region":"LOCATION","configuration":{}}]}'

where

  • NETWORK_NAME — any name you want to give to your network.

  • PROJECT_ID — the ID of the project where the network will be deployed. You can get project IDs by running curl -X GET "$APIURL/projects/" --header "$HDR_AUTH".

  • PROTOCOL — the protocol of the network you want to deploy:

    • corda — Corda
    • fabric — Hyperledger Fabric
    • quorum — Quorum
    • multichain — MultiChain

  • CONSENSUS — the consensus of the protocol you want to deploy:

  • NODE_NAME — any name you want to give to your first peer node deployed as part of the network.

  • NODE_TYPE — dedicated is the only available option for consortium networks.

  • NODE_ROLE — use the peer value for the role since you are providing node details for your peer node.

  • CLOUD_PROVIDER — choose the cloud provider for your node:

    • aws — Amazon Web Services
    • azure — Microsoft Azure
    • gcloud — Google Cloud Platform

  • LOCATION — choose the location for your network:

    • ap-southeast-1 — Singapore. Available only for Amazon Web Services (aws).
    • us-east-1 — the United States, Northern Virginia. Available only for Amazon Web Services (aws).
    • us-west-2 — the United States, Oregon. Available only for Amazon Web Services (aws).
    • uksouth — the United Kingdom, London. Available only for Microsoft Azure (azure).
    • asia-southeast1 — Singapore. Available only for Google Cloud Platform (gcloud).

Example to create a Corda network on Google Cloud Platform in Singapore:

curl -X POST "$APIURL/networks/" --header "$HDR_AUTH" --header "$HDR_CT" --data '{"name":"NETWORK_NAME","project":"PR-123-456","protocol":"corda","configuration":{"consensus":"single-notary"},"nodes":[{"name":"My node name","type":"dedicated","role":"peer","provider":"gcloud","region":"asia-southeast1","configuration":{}}]}'

See also API reference: Create Network.

​
Add a peer node to the network

curl -X POST "$APIURL/nodes/" --header "$HDR_AUTH" --header "$HDR_CT" --data '{"name":"NODE_NAME","network":"NETWORK_ID","type": "dedicated","role":"peer","provider":"CLOUD_PROVIDER","region":"LOCATION","configuration":{}}'

where

  • NODE_NAME — any name you want to give to your node.

  • NETWORK_ID — the ID of the network where the node will be deployed. You can get network IDs by running curl -X GET "$APIURL/networks/" --header "$HDR_AUTH".

  • CLOUD_PROVIDER — choose the cloud provider for your node:

    • aws — Amazon Web Services
    • azure — Microsoft Azure
    • gcloud — Google Cloud Platform

  • LOCATION — choose the location for your network:

    • ap-southeast-1 — Singapore. Available only for Amazon Web Services (aws).
    • us-east-1 — the United States, Northern Virginia. Available only for Amazon Web Services (aws).
    • us-west-2 — the United States, Oregon. Available only for Amazon Web Services (aws).
    • uksouth — the United Kingdom, London. Available only for Microsoft Azure (azure).
    • asia-southeast1 — Singapore. Available only for Google Cloud Platform (gcloud).

Example to add a node on Microsoft Azure in London:

curl -X POST "$APIURL/nodes/" --header "$HDR_AUTH" --header "$HDR_CT" --data '{"name":"My node name","network":"NW-123-456-7","type": "dedicated","role":"peer","provider":"azure","region":"uksouth","configuration":{}}'

See also API reference: Create Node.

​
Get the node access and credentials

curl -X GET "$APIURL/nodes/NODE_ID/" --header "$HDR_AUTH"

where NODE_ID — the ID of the node. You can get node IDs by running curl -X GET "$APIURL/nodes/" --header "$HDR_AUTH".

See also API reference: Retrieve Node.

You have created a consortium project, deployed a consortium network, added a node to the network, and retrived the node’s access and credentials.
