System and method for managing blockchain nodes

System and method for managing blockchain nodes

It mainly introduces how to efficiently process blockchain requests and quickly synchronize and restore node status by creating and managing blockchain node clusters. The following are the core points of the document:

Blockchain node management:

Node cluster: The system manages and processes blockchain requests by creating blockchain node clusters. Each cluster can contain multiple blockchain nodes, which can belong to the same or different blockchain networks.

Node state synchronization: When a node starts, it quickly synchronizes to the latest blockchain state by loading a blockchain state snapshot instead of downloading the complete blockchain data from the blockchain network.

Node dynamic management: The system is able to dynamically add, stop, and restart blockchain nodes to meet changing network needs.

Snapshot generation and storage:

Snapshot generation: The system is able to generate chain state snapshots on selected blockchain nodes, including full snapshots and incremental snapshots, to record changes in blockchain status.

Storage and access: The generated snapshots are stored in the data storage system to quickly restore the status of the blockchain node when needed. The node can initialize its chain state by mounting the snapshot volume.

Snapshot verification: Before the snapshot is used to initialize a new node, the system will encrypt and verify the blocks in the snapshot to ensure the integrity and accuracy of the snapshot data.

Node health check and automatic recovery:

Health check: The system performs health checks by collecting telemetry data of blockchain nodes to determine the operating status and performance of the nodes.

Automatic recovery: For detected unhealthy nodes, the system can automatically perform recovery operations, such as restarting nodes or deploying new node instances.

Route adjustment: The system can dynamically adjust routing weights according to the health status of nodes to optimize network traffic distribution and avoid routing requests to unhealthy nodes.

Scalability and compatibility:

Scalability: The system supports expanding the capacity of blockchain node clusters by adding new computing instances to meet growing network needs.

Compatibility: The system can support multiple blockchain protocols and types, allowing nodes of different blockchain networks to be deployed and run while maintaining compatibility with new types of blockchain nodes.

Security and reliability:

Cryptographic verification: All snapshot data is cryptographically verified before use to ensure the security and integrity of the data.

Fault tolerance mechanism: The system improves the fault tolerance of the entire blockchain infrastructure by dynamically selecting healthy nodes for snapshot generation and automatic recovery operations.

System architecture and components:

Control system: Responsible for overall management and coordination of the operation of blockchain node clusters.

Storage system: used to store blockchain status and snapshot data.

Discovery system: records and manages the status information of blockchain nodes.

Snapshot system: responsible for generating, verifying and storing snapshots of blockchain nodes.

Agent and gateway: the agent is responsible for managing and controlling a single blockchain node, while the gateway is used to route and forward blockchain requests.

Implementation and method flow:

Method flow: The document describes in detail the entire method flow from determining the blockchain node cluster, processing blockchain requests to managing the blockchain node cluster, including specific steps such as node deployment, state synchronization, snapshot generation and node stop.

Implementation: Through specific implementations, it shows how to apply the system and method in practice, including the configuration of hardware devices, the execution of software instructions, and the interaction between different components.

These points provide a comprehensive overview of the system and method for managing blockchain nodes described in the document, including its core functions, workflow, system architecture and implementation details.
