+# Babylon BTC Staking Indexer
+
+## Overview
+
+The **Babylon BTC Staking Indexer** is a core component of the 
+Babylon blockchain’s staking architecture, responsible for syncing delegation 
+and finality provider events from both the **Babylon blockchain (BBN)** and 
+**Bitcoin (BTC)**. It processes, stores, and transforms on-chain events into 
+API-friendly data structures, enabling the Babylon Staking API to efficiently 
+serve staking-related data to the frontend.
+
+### Key Responsibilities
+
+- **Delegation Sync**: Syncs delegation and Babylon&BTC-related events, storing them in 
+MongoDB for easy retrieval.
+- **Finality Provider Sync**: Tracks and updates the state of finality providers
+ (FPs), including status changes, creation, and edits.
+- **Global Parameters Sync**: Syncs global parameters necessary for the staking 
+mechanism.
+- **Event Replay(pending)**: Allows manual operations like event replays, triggered by 
+the Admin Portal or CLI, to recover or adjust state after chain forks or re-orgs.
+
+## Architecture
+
+The Babylon Indexer interacts with the following components:
+
+- **BBN (Babylon Blockchain)**: Receives delegation and finality provider events
+ via Cosmos CometBFT `/block_results` (over gRPC for better performance), as well
+ as websocket subscription on events.
+- **BTC (Bitcoin)**: Syncs withdrawal transactions and other BTC-related events.
+- **MongoDB**: Serves as the storage layer where delegation, global parameters 
+and finality provider data is stored.
+- **API Event Queue**: The indexer pushes API-related events into a queue 
+(RabbitMQ), consumed by the Babylon API for frontend-facing operations.
+- **Admin Portal/CLI**: Provides interfaces for triggering event replays and 
+other manual interactions with the indexer.
+- **Data Transformation Service (Optional)**: Transforms delegation data from 
+the indexer into other formats to backfill or migrate data for API as needed.
+

+
+## Synchronization Process
+
+The workflow involves:
+
+1. **Bootstrap Process**: The indexer starts by syncing all events from the 
+last processed Babylon block height to the latest height. 
+This is a continuous process until it catches up with the most recent block.
+2. **Real-time Sync**: After catching up, the indexer subscribes to 
+real-time WebSocket events for ongoing synchronization.
+3. **Raw Data Synchronization**: The indexer primarily handles the 
+synchronization of:
+   - **Delegation**: Storing and tracking delegation data.
+   - **Finality Provider**: Monitoring state changes and updates for 
+   finality providers.
+   - **Global Parameters**: Syncing parameters relevant to staking, unbonding, 
+   and slashing.
+
+4. **RabbitMQ Messaging**: When a state change occurs in any delegation, 
+the indexer emits a message into RabbitMQ. This allows the Babylon API to 
+perform metadata and statistical calculations, such as total value locked (TVL) 
+computations.
+5. **Bitcoin Node Sync**: The indexer also syncs with the Bitcoin node to 
+check if delegations are in a withdrawn state, ensuring accurate tracking of 
+withdrawal transactions.
+
+## Installation & Setup
+
+### Requirements
+
+- **Go**: Version `1.23.2` or higher is required.
+- **MongoDB**: A MongoDB instance with replica sets enabled is required
+
+1. Clone the repository
+
+```bash
+git clone git@github.com:babylonlabs-io/babylon-staking-indexer.git
+cd babylon-staking-indexer
+```
+
+2. Install dependencies
+
+```bash
+go mod tidy
+```
+
+3. Run the service
+
+```bash
+make run-local
+```
