- The diagram you've crafted outlines a sophisticated system architecture involving multiple components within a network that manages data distribution from Validators to various end services. Here's a comprehensive breakdown of how these components interact:
- ### Components:
- 1. **Archiver**:
- - **Function**: This component collects complete network state data, including transaction histories and account states, from a network of Validators.
- - **Data Management**: It writes this data into log files for retrieval and distribution.
- 2. **Distributor**:
- - **Function**: Serves as a hub for distributing data collected by the Archiver.
- - **Data Retrieval**: Reads data from the log files created by the Archiver.
- - **Data Streaming**: Establishes socket connections to send real-time data to the Collectors.
- - **Historical Data**: Provides APIs for subscribers who need access to historical data.
- 3. **Collector**:
- - **Function**: Receives data streamed from the Distributor.
- - **Data Handling**: Uses API or stream methods to forward data to a Collector Server, which processes or transforms the data before it reaches the JSON-RPC Server.
- 4. **Collector Server**:
- - **Function**: Acts as an intermediary processor and forwarder.
- - **Data Streaming**: Receives data from the Collector and streams it to the JSON-RPC Server, ensuring that data is in the proper format and timely.
- 5. **JSON-RPC Server**:
- - **Function**: Provides a communication interface for RPC Servers through a standardized JSON-RPC protocol.
- - **Data Collection**: Acts as a firehose collector, gathering and processing real-time data for RPC Servers.
- 6. **RPC Servers**:
- - **Function**: Handle requests from client applications such as wallets or other services.
- - **API and Websockets**: Offer APIs and establish Websockets to facilitate real-time and reliable data transactions with end-user applications.
- 7. **Wallets and Services**:
- - **Function**: End-user interfaces that interact with RPC Servers to retrieve blockchain data or perform transactions.
- 8. **Service Validator**:
- - **Function**: A specialized agent that does not participate directly in network consensus but validates and processes data requests.
- - **Network Interaction**: Queries the network for data based on requests routed through RPC Servers.
- - **Data Queries**:
- - **Active List of Validators**: Maintains and provides data concerning active network validators.
- - **Collector**: Manages and provides collected data relevant to specific queries or tasks.
