Ant Blockchain | Billing | If an Ant Blockchain instance exceeds its free storage quota, the system automatically scales storage capacity. Based on Alibaba Cloud NAS (Capacity), this feature ensures your business runs without interruption or noticeable performance impact. | August 10, 2023 | |
Ant Blockchain | Node management | Provides graphical visualization of node resources. | June 30, 2023 | |
Ant Blockchain | Change configuration | You can now upgrade Ant Blockchain from Professional Edition to Enterprise Edition on the console. | June 6, 2023 | |
Hyperledger Fabric | Chaincode as a service | Hyperledger Fabric chaincode containers now build and run on Kubernetes (K8s), significantly improving resource allocation, reliability, and stability. | September 29, 2022 | |
Ant Blockchain | Data export service | The data export service now supports both the main chain and subchains, allowing data export to MySQL databases. | December 28, 2021 | |
Hyperledger Fabric | Hyperledger Fabric 2.2 instances are now generally available, and the purchase option for Hyperledger Fabric 1.4 instances is retired. | The purchase option for new Hyperledger Fabric 1.4 instances is retired. However, existing users of version 1.4 can still create both version 1.4 and 2.2 instances. Version 2.2 is now generally available to all users. | December 14, 2021 | |
Ant Blockchain | Subchain feature REST access service |
| July 5, 2021 | |
Hyperledger Fabric | Added support for Hyperledger Fabric v2.2 | 1. Aligns with the Hyperledger Fabric v2.2 community release. This version introduces a new chaincode lifecycle management model where consortium members vote to approve chaincode content, endorsement policies, and parameters. It also allows for dynamic updates to chaincode endorsement policies and supports independent endorsement policies for each private data collection. 2. Supports interoperability for Hyperledger Fabric v2.2. Self-hosted or external organizations can join an Alibaba Cloud BaaS consortium, and Alibaba Cloud BaaS organizations can join channels in an external or self-hosted consortium. | April 15, 2021 | |
Hyperledger Fabric | Cloud service integration: DataV | Quickly integrate blockchain applications with DataV for data visualization. | May 26, 2020 | |
Ant Blockchain | Upgraded smart contract trial chain | Provides the latest version of the smart contract trial chain for an enhanced user experience. | May 12, 2020 | |
Hyperledger Fabric | Interoperability | Provides a flexible solution for building blockchain networks across different cloud providers or private environments. | March 17, 2020 | |
Hyperledger Fabric | Cloud service integration: Function Compute | You can use Function Compute to automatically trigger off-chain business logic from on-chain events. Upload your code to Function Compute and map it to specific blockchain events. When BaaS detects a matching on-chain event, it automatically provisions resources and runs your code elastically and reliably. | February 27, 2020 | |
Hyperledger Fabric | Cloud service integration: Message Queue (MQ) | Configure mappings to automatically publish on-chain events to Message Queue (MQ). When a matching event occurs, BaaS sends a message to the specified MQ topic. You can then subscribe to these topics to process the event messages. | February 27, 2020 | |
Hyperledger Fabric | Cloud service integration: Database | Export on-chain data to a relational database by mapping your blockchain data to database tables. This feature automatically extracts the specified data from blocks and inserts it into the target tables. You can then use SQL or other database tools to process the data. | February 27, 2020 | |
Hyperledger Fabric | Cloud service integration: Content Moderation | Data on a blockchain is immutable, making it difficult to remove illegal or non-compliant information once it is on-chain. To prevent this, you can integrate with Alibaba Cloud Content Moderation. When you call a smart contract by using the REST API, you can specify parameters for Content Moderation to scan automatically. This helps prevent non-compliant information from being recorded on the blockchain. | February 27, 2020 | |
Hyperledger Fabric | Cloud service integration: External services | You can automatically trigger your own business applications or third-party services from on-chain events. Map blockchain events to an external HTTP service. When a matching on-chain event occurs, BaaS automatically sends a request to that HTTP service. | February 27, 2020 |
