Implement Indexer Service

[raduciobanu22]

Objective
Create a service that continuously monitors the Alephium blockchain for new blocks and events, processes them according to configured handlers, and stores the results in the database.

Scope of Work

1. Event Processing

• Implement plugin system for event handlers
• Create event filtering mechanism
• Add event validation and transformation
• Implement error handling for failed processing

2. Service Management

• Create service lifecycle management
• Implement graceful shutdown
• Add health checking

3. Data Consistency

• Implement block reorganization handling
• Add data validation mechanisms
• Create data integrity checks
• Implement recovery procedures

Requirements

• Plugin-based architecture for extensibility
• Robust error handling and recovery
• Comprehensive logging
• Complete test coverage

Can I take care of this issue?

I am a backend developer and I can build backends using Rust and NodeJS. I believe I have the knowledge and skill to work on this issue.

I can work on this indexer service. I understand what is required to complete this task.

[estherbreath]

I am interested in this issue and would like to work on it.

To implement the Indexer Service for Alephium, I will focus on the following key aspects:

• Set up event listeners for new blocks and events on the Alephium blockchain.

• Develop a plugin system for flexible event handler registration and execution.

• Implement robust error handling, logging, and data consistency checks throughout the indexing process.

ETA: 2 days

[od-hunter]

Hi, please can I be assigned this please? I would love to be the given the opportunity to solve this issue please. I have experience in html, css, JavaScript, TypeScript, cairo and rust.

This is a summary of how I intend to solve this issue:
1.⁠ ⁠Firstly, I’ll implement a plugin-based architecture to handle event processing, implement filtering logic to handle specific event types, validate event data against schemas and transform as necessary before processing and use retry logic, logging, and alerting to manage failed events.
2.⁠ ⁠⁠I’ll create a service manager class to handle service initialization, starting, stopping, and monitoring, I’ll use signals or lifecycle hooks to handle shutdowns and implement a health check endpoint that checks service status and dependencies.
3.⁠ ⁠I’ll i⁠mplement logic to detect and handle blockchain reorganizations, I’ll implement data integrity checks when processing and storing events and implement data recovery using a queue.
4.⁠ ⁠⁠I’ll design components with decoupling in mind to support future plugins an integrate structured logging (e.g., using winston or log4js in Node.js) for tracking events, errors, and recovery actions.
5.⁠ ⁠⁠Lastly, I’ll use unit tests, integration tests, and mocks (e.g., jest, mocha) to cover event handlers, database operations, and recovery procedures.

Kindly assign me please, I’m up for the task.
