Solution description
Introduction to concept
Xuper Chain Baidu Xuper Chain is a self-developed blockchain 3.0 solution by Baidu, featuring powerful network throughput capacity, high-concurrency validity verification capability and scalable storage capacity.
Super Node/Supervisory Node Super nodes are special nodes in Xuper Chain. The distributed computing technology is adopted to ensure that the storage and computing of each node can be scaled, thus providing continuous storage and computing support for the blockchain network. Under the non-POW consensus mechanism, super nodes calculate transactions submitted on the chain and execute contracts. Super nodes improve computing efficiency by combining multi-core parallel computing with distributed computing. Supervisory nodes are mainly used for transaction verification.
- Smart contracts Since the UTXO (Unspent Transaction Output) model has better concurrency than the account balance model, the underlying layer of Xuper Chain is based on the UTXO model, which extends support for smart contracts and can load different contract virtual machines.
Three-dimensional Network Xuper Chain implements a three-dimensional network on the blockchain using in-chain parallel technology, returnable sidechain technology and parallel chain technology Xuper Chain implements a three-dimensional network on the blockchain using in-chain parallel technology, returnable sidechain technology and parallel chain technology.
- In-chain parallelism: Xuper Chain uses transaction mining to form a Directed Acyclic Graph (DAG), enabling concurrent transaction execution.
- Returnable sidechain: Xuper Chain offloads complex smart contracts to sidechains, utilizing parallel resources without consuming mainchain resources. When sidechain return conditions are fulfilled, sidechain merging is triggered proactively.
- Parallel chain: Xuper Chain allows the creation of independent and authentic blockchain systems using the root chain.

Environment preparation
Apply for blockchain solution permissions
- Sign in to the official website of Baidu AI Cloud Blockchain Solution.
- Click Apply Now to enter Application for the Use of Blockchain Solutions, fill in the application as required, and then click Submit.
Warm Reminder: Once we receive your application, it will enter the review stage. Upon successful review, a dedicated representative will contact you based on the provided contact details and your requirements to discuss further. If you’ve been notified that your blockchain solution access has been activated, log in to the console, navigate to Computing - Cloud Container Engine (CCE) - Solutions - Xuper Chain Solution, and begin creating your application.
Create a container cluster
Create the operating environment for blockchain applications - container clusters. For specific operation steps, please refer to Create Cluster
Parameter configuration
After the container cluster is created successfully, start deploying the Xuper Chain network. Parameters support one-click configuration. Users only need to select and configure parameters as prompted on the Xuper Chain deployment page:
- Select cluster: Select the cluster used to deploy the Xuper Chain. If no cluster has been created, click Create Now to redirect to the container cluster creation page
- Xuper Chain network name: Customize your Xuper Chain network name to identify your network information
- Single block reward: The reward amount for each block when the super node generates a block
- Decay height: The number of blocks after which the reward starts to decay during block generation
- Decay factor: After generating a certain height of blocks during block generation, the new reward equals the current reward multiplied by the decay factor
- Initial allocation of super bitcoins: When creating a network, a pre-allocated number of super bitcoins is given to the management account, which defaults to the account of the first super node
- Super node account: Nodes with bookkeeping and block-generating rights, with account information randomly generated
- Supervisory node account: Nodes with only supervisory rights, used for transaction verification
For example, if the block reward is 100, the decay height is 100, and the decay coefficient is 0.5 The reward for each block from block 1~ to 100 is 100; the reward for each block from block 101~ to 200 is 50; the reward for each block from block 201 to 300 is 25, and so on, with the reward gradually converging.
