Alibaba Cloud Blockchain as a Service (BaaS) supports three blockchain frameworks: Ant Blockchain, Hyperledger Fabric, and Quorum (an enterprise-focused version of Ethereum). This guide explains the available editions and their use cases, then walks you through the purchase process for each framework.
Before you begin
Before choosing a framework or edition, understand the key building blocks:
Consortium: A group of organizations that share a blockchain network. You create a consortium first, then add blockchain instances to it.
Organization: An individual participant in a consortium. Each organization runs its own peer nodes.
Channel: A private communication channel within a consortium that restricts data visibility to specific organizations.
Node: A server that stores the ledger and processes transactions.
Choose a framework
| Framework | Best for |
|---|---|
| Ant Blockchain | Enterprises that need a high-throughput, managed blockchain with a simplified setup process |
| Hyperledger Fabric | Enterprises that need fine-grained access control, multi-organization consortia, or interoperability with external systems |
| Quorum | Enterprises migrating from or integrating with Ethereum-based smart contracts |
Purchase process - Ant Blockchain
Step 1: File a declaration of use
A declaration of use is required before every new instance purchase — whether you are a first-time buyer or are adding a new instance to an existing account.
You must declare the purpose in advance. This is required for first-time purchases, renewals, and the creation of new blockchain instances.
Log on to the console. In the left-side navigation pane, choose AntChain > Contract Chain to open the My Consortium page.
In the upper-right corner of the page, click Declaration of Use in the yellow area. Select the intended use in the pop-up window and click Submit Declaration.
If you select Others, enter a description of no more than 30 characters in the text box.

Follow the on-screen instructions to complete the declaration.
The Description of Your Intended Use field accepts up to 300 characters.
Check the review status.
Click Declaration Filing Record in the upper-right corner of the My Consortium page.
In the window that appears, view the declaration status:
Approved: The declaration is approved. Proceed to purchase.
To be reviewed: The review is in progress. The review typically takes 1–2 days. A notification banner also appears at the top of the My Consortium page:

Rejected: Click Re-Submit Declaration in the red banner at the top of the My Consortium page to resubmit.

Step 2: Create a consortium
Skip this step if you are adding a blockchain to an existing consortium.
In the console, choose AntChain > Contract Chain.
Click Create Consortium. Enter a name and description, then click Submit.
Step 3: Purchase a blockchain instance
In the consortium list, click Manage to open the chain management page.
Click Create Blockchain to go to the purchase page. The Consortium field is pre-populated with all consortia in your account.
Configure the following parameters:
Parameter Description Region Select the region closest to your applications to minimize network latency. Consortium Select an existing consortium or create one. Blockchain Name Enter a name of 1–100 characters using digits, letters, and hyphens (-). You can modify the name at any time on the console chain management page. Duration Select a subscription period. Instances are subscription-based. Click Buy Now and complete the payment.
After payment, the instance appears in the console. Instance creation takes 10–30 minutes because each instance uses exclusive dedicated resources. For pricing details, see Specifications and billing methods.
Purchase process - Hyperledger Fabric
Purchase options
Purchase from either the product page or the console:
Product page: Go to the Alibaba Cloud BaaS product page and click Buy Now.
Console: Log on to the Alibaba Cloud BaaS console. On the Hyperledger Fabric page, click Create Consortium or Create Organization, then click Purchase consortium/organization resources.
Configure instance parameters
On the purchase page, configure the following:
| Parameter | Description |
|---|---|
| Region | Select the region closest to your business applications. |
| Instance parameters | Select an edition based on your requirements. See Purchase reference - Hyperledger Fabric for a feature comparison. |
| Duration | Select a subscription period. Instances are subscription-based. |
If you have previously created a Fabric V1.4 or V2.2 instance, you can continue creating instances of those versions or create a new instance of Fabric V2.5. Mixed networking between different versions is not supported.
New accounts can only create Fabric V2.5 instances by default. To create a V1.4 or V2.2 instance, submit a ticket.
Click Buy Now and complete the payment. For pricing details, see Specifications and billing methods.
