Supply Chain Finance

Supply Chain Finance

Uses decentralized, tamper-proof, shared ledgers to ensure transparency and fairness, helping SMEs improve their credit ratings while cutting risk management costs.


High Efficiency

Shared ledgers allow all parties to use and recognize the same set of data, streamlining the financing process.

Low Costs

Complete recording and tracking of logistics, information flows, and capital lower risk management and financing costs.

High Credibility

Fair and transparent transactions help SMEs improve their credit ratings and ultimately obtain preferential interest rates for loans.

Supply Chain Tracing

Supply Chain Tracing

Each party can maintain ledgers, ensuring real-time and authentic data updates, and use product-unique tracing codes, ensuring authenticity of commodities and the distribution processes.



Commodity and distribution information is encrypted in the blockchain, preventing tampering.


Unique commodity codes in the blockchain make it possible to completely and transparently record ownership and distribution.

Easy to Trace

Tamper-proof, transparent ledgers allow parties to understand commodity distribution and facilitate supervision by regulators.

Digital Assets

Digital Assets

Automated transaction capabilities such as asset ownership confirmation and accounting reconciliation support efficient exchange of digital assets and prevent in-chain falsification.


Fewer Disputes

Each asset, with an immutable timestamp, is registered publicly, facilitating tracking of asset permissions.

Higher Efficiency

Trust, sharing, and security and privacy protection ensure smooth distribution of digital assets.

Cheating prevention

Tamper-evident ledgers prevent forgery and cheating.

Notarization for Crowdfunding

Notarization for Crowdfunding

Funding is traceable and information is open, transparent, and shared across the entire network, resolving trust issues between organizations.


Increased Efficiency

Shared ledgers break down the barriers among people and organizations. Smart contracts enable automatic transaction execution.

Effective Control

Distribution, use scope, and even validity period of capital are effectively controlled.

Improved Public Trust

Algorithm-based consensus between parties at all blockchain nodes makes transactions open and fair, improving mutual trust.

New Features


  • Quick Deployment

    Reduces blockchain deployment time from days to minutes.

  • Dynamic Joins

    Cloud tenants are invited to form consortia. Each tenant has a separate VPC, ensuring security and controllability.

Quick Deployment

Lowered Threshold

  • Adopting Huawei's best practices, deployment time is significantly reduced and configuration is primarily automated, saving time.

Masking Underlying Technology

  • The high availability, high performance, and secure blockchain system is ready for immediate use. Users can focus on their business, without concerning themselves with the underlying technologies or having to invest in platform construction.

Dynamic Joins

Convenient and Flexible

  • Consortium blockchains can be formed dynamically. Consortium members share the blockchain network costs.

  • Pluggable Consensus Algorithm

    Provides multiple consensus algorithms to adapt to diverse scenarios.

  • Node Auto Scaling

    Supports auto scaling of peers and orderers to meet high availability demands without needing a system reboot.

Pluggable Consensus Algorithm

  • Solo (for Simplicity and Testing)

    Solo requires only one node for transaction ordering. It does not support byzantine fault tolerance, but features quick startup and resource saving.

  • Fast Byzantine Fault Tolerance (FBFT)
    FBFT is a consensus algorithm with high performance and availability. It requires at least four nodes for transaction ordering and tolerates byzantine faults at a maximum of (N – 1)/3 nodes, where N indicates the total number of blockchain nodes involved in transaction ordering. For example, assume that there are seven nodes. Transactions can be correctly ordered if not more than two nodes experience byzantine faults. This algorithm is recommended in the production environment.

  • Kafka (Crash Fault Tolerant)

    A secure, reliable, and highly scalable consensus algorithm, which is ideal for large capacity scenarios where high read/write speed is not required and a small number of transactions take place.

  • Raft (crash fault tolerance)

    Raft is a high-speed crash fault tolerant (CFT) ordering service that tolerates faults at a maximum of (N – 1)/2 orderers, where N indicates the total number of orderers. For example, transactions can be correctly ordered if only one of a total of three orderers encounters faults.

Node Auto Scaling

High Availability

  • Compliant with Kubernetes; support for masters, shared storage, and node fault recovery.

Dynamic Scaling Out

  • Docker containers run on nodes and can be seamlessly scaled out based on user requirements without interrupting services.

  • Visible Code Mgmt.

    Allows chaincode mgmt. on the web throughout the entire lifecycle, including viewing, installation, and instantiation.

  • Cloud Monitoring

    Offers an open platform to monitor data and resources, generate alarms, and send notifications in real time.

Visible Code Mgmt.

Cloud Monitoring

Automated O&M

  • Executes active upgrades on the underlying blockchain platform and updates patches automatically to seamlessly integrate with the HUAWEI CLOUD O&M system.

Enterprise-grade monitoring

  • Performs multi-dimensional monitoring on clusters 24/7, and supports user-defined alarms across multiple channels.
