Enterprise blockchain adoption requires high throughput, strong access control, reliable infrastructure, and low operational overhead. Alibaba Cloud Blockchain as a Service (BaaS) provides two blockchain frameworks — Ant Blockchain and Hyperledger Fabric — each designed to meet these requirements.
Ant Blockchain
High performance
Ant Blockchain handles up to 25,000 notary blockchain transactions per second, built on advanced concurrency and consensus technologies. This throughput supports high-concurrency scenarios in the finance industry.
High reliability
The consensus mechanism is based on Practical Byzantine Fault Tolerance (PBFT), which provides Byzantine fault tolerance (BFT), automatic recovery of the consensus state, and automatic load balancing. The platform also supports buffering during peak workloads, multiple backups, and storage distribution balancing to keep applications available when traffic spikes.
Dual-permission protection
Ant Blockchain applies two independent layers of access control:
First layer: The consortium blockchain is visible only to trusted participants and hidden from other users.
Second layer: Every participant must submit a CA certificate application and receive approval before joining the consortium.
Together, these layers prevent unauthorized access at both the network and identity levels.
Cross-network deployment
Deploy blockchain nodes across cloud platforms based on your business requirements. Some nodes can run on Alibaba Cloud while others run in your own IT environment, giving you flexibility without locking your infrastructure to a single platform.
Data privacy and security
Chain plaintext data or encrypt it using symmetric encryption. To protect sensitive data, encrypt the encryption key with a separate private key — the resulting ciphertext and encrypted key are both stored on-chain. Manage private keys with specific key derivation functions (KDFs) and share different keys based on security levels and sharing ranges. Ant Blockchain also supports shared privacy models for multi-party scenarios.
Ease of use
Ant Blockchain removes the need to understand low-level blockchain mechanics. Focus on designing and developing blockchain applications while the platform handles the underlying infrastructure.
Hyperledger Fabric
Security
Alibaba Cloud BaaS for Hyperledger Fabric provides security across three levels:
Identity level
Each enterprise has an independent CA service to meet its own identity requirements.
Built-in risk control and operation auditing prevent a "fat-finger error".
Network level
Multi-dimensional network isolation, network access control, and attack protection.
A consortium blockchain management system supports multi-enterprise collaboration.
Data level
Encryption and decryption based on China's recommended cryptographic algorithms.
High availability
The service provides end-to-end high availability across blockchain nodes, service administration, and container clusters, ensuring business continuity. The bottom-layer storage of the blockchain ledger reaches 99.999999999% reliability and scales up quickly without interruption.
Performance
Alibaba Cloud BaaS runs on high-performance cloud servers with high-bandwidth networking and high-concurrency, high-throughput storage, maximizing the performance potential of your blockchain network.
Ease of use
Build an enterprise-level blockchain network quickly using a graphical interface that supports configuration, deployment, management, and monitoring across multiple networks.
Develop blockchain applications using REST API, a software development kit (SDK), or the BaaS VSCode Plugin, lowering the barrier for developers.
Integrate with Alibaba Cloud services including Function Compute, Message Queue (MQ), and Content Moderation for on-chain and off-chain collaboration.
Save on bottom-layer infrastructure and daily operations and maintenance (O&M) costs, freeing your team to focus on application innovation.
Openness and ecosystem
Alibaba Cloud BaaS supports blockchain applications and data under the Hyperledger Fabric framework, and development results are shared with the open source blockchain community. Alibaba Cloud integrates developed blockchain systems to build an open, capable, and standardized blockchain ecosystem.
Global deployment
With data centers around the world, Alibaba Cloud BaaS helps you deploy business systems globally. Built on Alibaba Cloud's proven overseas compliance processes and practices, the service supports building secure, compliant, and operational business systems across regions.
