Overview of Lisk Service

Lisk Service is an integral part of the Lisk ecosystem, designed to provide enhanced data accessibility and interaction capabilities for blockchain applications. It is built using JavaScript and runs on the Node.js V8 virtual machine. The architecture is based on extensible microservices, ensuring high performance and scalability. Each microservice focuses on providing specific functionalities, and data is served in JSON format via a public RESTful API.

Lisk Service allows users to access and browse blockchain data effortlessly, providing an API that calls to retrieve detailed information about blocks, transactions, accounts, and network statistics, contributing to better data availability. The microservices architecture ensures that each service is focused on a specific functionality, which simplifies maintenance and scalability, making extension and customization of the services easier. It also provides real-time access to blockchain data, enabling developers to build applications that require up-to-date information.

Components of Lisk Service

Lisk Service consists of different components that work together to provide a comprehensive data service for the Lisk blockchain. The data aggregation component collects and processes data from the blockchain. This includes transaction histories, account balances, block details, and more. The aggregated data is then made accessible through the API endpoints.

Lisk Service continuously collects data from the blockchain, ensuring that all relevant information is captured and stored. The collected data is processed to extract meaningful information and insights, including calculating statistics, generating summaries, and indexing data for efficient retrieval. Processed data is stored in a high-performance database, optimized for fast read and write operations. This ensures that data can be retrieved quickly when needed.

API Endpoints

Lisk Service offers a wide range of API endpoints that developers can use to interact with the blockchain. These endpoints provide access to various types of data, including:

• Blocks and Transactions: Retrieve details about specific blocks and transactions, including timestamps, transaction amounts, and involved addresses. This data is essential for building applications that need to track and analyze blockchain activity.
• Account Data: Access information about account balances, transaction histories, and account metadata. This allows developers to create applications that manage user accounts and display relevant information.
• Delegate Voting Statistics: Obtain voting statistics for delegates, including vote counts and rankings. This data helps applications that involve governance and voting mechanisms.
• Network Peers: Get information about network peers, including their geolocation and status. This is useful for monitoring the health and connectivity of the blockchain network.

Data Access

Lisk Service supports advanced features such as geolocation data and detailed network analytics to integrate more complex data into their applications, providing a richer user experience. It can provide geolocation information for network peers, helping developers understand the geographical distribution of nodes, which can be used to optimize network performance and ensure reliable connectivity.

Detailed analytics on network performance, including transaction throughput, block propagation times, and node latency. These analytics help developers monitor and optimize the performance of their blockchain applications.

Comparison with Lisk Core API

The Lisk Core API and Lisk Service API serve different purposes and offer varying levels of data access. The Lisk Core API is designed for managing a single node and provides basic blockchain data. In contrast, the Lisk Service API offers a holistic view of the entire network, with enhanced data capabilities.

• Lisk Core API: Focuses on node management and basic data retrieval. It provides endpoints for interacting with the blockchain at a low level, suitable for tasks such as submitting transactions and querying block data
• Lisk Service API: Provides comprehensive network data, including metadata, detailed transaction histories, and network statistics. It offers a higher level of abstraction, making it easier for developers to build complex applications without needing to manage individual nodes.
