ZKSync & Ethereum Governance Event Monitor

Problem

The ZKSync & Ethereum Governance Event Monitor project aimed to create a transparent, scalable, and efficient monitoring system for governance-related events on ZKSync Era and Ethereum Mainnet. By transforming blockchain events into structured RSS feeds, this solution provides stakeholders and developers with accessible and real-time insights into governance activities.

The collaboration with ScopeLift ensured a robust design and seamless implementation within a tight one-month timeline, leveraging cutting-edge technologies and best practices for scalable, cloud-based deployments.

Objectives

1. Governance Event Tracking: Capture and process governance-related blockchain events, including proposal creation, execution, cancellation, and administrative changes.
2. RSS Feed Integration: Present event data through user-friendly, regularly updated RSS feeds.
3. Scalable and Reliable Architecture: Utilize Google Cloud Platform (GCP) and Docker for deployment, ensuring scalability and reliability.
4. Transparent Monitoring: Provide structured and archived historical data for long-term accessibility.

Solution

The project utilized a modular, cloud-based architecture, encompassing blockchain networks, backend services, storage, and frontend components.

Key Features

• Event Detection: Monitors and processes governance events in batches for efficiency.
• RSS Feed Updates: Automatically generates and updates feeds with new events while archiving old entries for transparency.
• Scalability: Supports large-scale RPC usage with over 150,000 daily calls across Ethereum Mainnet and ZKSync Era.

Core Functionalities

1. Event Monitoring

• Captures governance-related events such as proposal creation, execution, and cancellations.
• Supports multiple blockchains: Ethereum Mainnet and ZKSync Era.

2. RSS Feed Integration

• RSS feeds allow users to track events in real-time.
• Archived RSS entries ensure historical data remains accessible.

3. Infrastructure
