[Feature]: Background Job Queue for Blockchain Operations

[SudiptaPaul-31]

🔍 Problem Statement

Description

Introduce a background job system for operations that should not block API requests. This ensures scalability, reliability, and smooth user experience when handling blockchain-related tasks.

---

Jobs

• Blockchain transaction monitoring — track confirmations and status updates asynchronously.
• Notification processing — send real-time alerts without blocking API calls.
• Contract synchronization — keep off-chain database in sync with on-chain state.
• Deadline checks — monitor contract/milestone deadlines and trigger events.

---

Tasks

• Implement job queue system (e.g., BullMQ, Celery, or custom worker pool).
• Define job lifecycle — queued → processing → completed → failed.
• Add retry mechanism — automatically retry failed jobs with exponential backoff.
• Prevent duplicate processing — enforce idempotency checks for queued jobs.
• Track job status — expose API/DB records for monitoring job progress.
• Error logging — capture and store errors for debugging and alerting.
• Scalability support — allow horizontal scaling of workers.

---

Acceptance Criteria

• ✅ Retry failed jobs — jobs automatically retried with configurable limits.
• ✅ Prevent duplicate processing — same job cannot be executed twice.
• ✅ Job status tracking — developers can query job state (pending, running, failed, completed).
• ✅ Error logging included — failures are recorded with stack trace and metadata.
• ✅ Non-blocking API requests — blockchain operations run asynchronously in background.
• ✅ Scalable architecture — queue can handle high throughput reliably.

📈 Expected Impact

High — Would significantly improve user experience
