babylon-staking-indexer

Description

The babylon-staking-indexer is a core indexing service that processes and tracks staking-related transactions from the Babylon blockchain. It ensures that staking-related events are captured, indexed, and made available for further processing.

This module is responsible for

• indexing blockchain staking transactions — capturing staking, unbonding, and withdrawal events

• interacting with the Babylon blockchain — retrieving real-time staking data

• processing event queues — ensuring staking transactions are correctly managed

• storing and managing indexed staking data within a database

• providing staking status updates for users and applications

Here are its key functionalities:

• Blockchain event indexing — listens for staking transactions and processes them

• Database management — stores staking transaction details, including lock durations

• Queue processing — handles staking-related events in an asynchronous queue system

• Observability and logging — monitors system state and provides logging and metrics

Invariants

• Only authorized services should be able to interact with the indexer.

Test coverage

Cases covered

• Blockchain event processing — capturing staking-related transactions from the Babylon blockchain and validating correct indexing and storage of staking data

• Database interaction — ensuring staking transactions are stored and retrieved correctly and validating indexing and retrieval for efficient query performance

• Queue-message handling — validating that staking events are correctly queued and processed and ensuring retry limits are enforced

Attack surface

Without proper rate limits, an attacker could flood the queue with excessive staking messages. Implementing retry limits and validation rules is necessary.
