Redis AI Challenge: Beyond the Cache

This is a submission for the Redis AI Challenge: Beyond the Cache.

What I Built 🛠️

Asguard is a next-generation decentralized security & intelligence platform designed for IoT networks, sensitive data pipelines, and enterprise systems.

We aimed to solve three problems simultaneously:

Real-time threat detection using AI inference – Detect anomalies, security breaches, and suspicious IoT device behavior within milliseconds.
Immutable event logging with blockchain – Guarantee that every logged event is tamper-proof, verifiable, and auditable.
Lightning-fast decision-making with Redis 8 – Use advanced Redis features beyond caching to ensure ultra-low latency responses.

Our vision is to provide a secure AI assistant that can monitor, detect, and react to events in milliseconds, while ensuring data authenticity and trust through blockchain technology.

Demo

Imagine this scenario:

A connected factory has hundreds of IoT sensors sending telemetry data every second.

Redis Streams capture the incoming data in real time.
RedisAI runs inference on the data using pre-trained anomaly detection models.
When a threat is detected, an alert is sent instantly via Redis Pub/Sub.
The event is stored immutably on the blockchain for verification.

How I Used Redis 8 🚀

Beyond caching, Redis 8 was at the heart of Asguard’s performance:

Redis Streams → For high-speed ingestion of IoT device data.
RedisAI → For executing AI models directly inside Redis, eliminating external API calls and reducing latency.
RedisJSON → For structured, queryable storage of processed events.
RedisSearch → For fast, indexed search of security events.
Redis Pub/Sub → For broadcasting real-time alerts to connected dashboards and monitoring tools.

This combination allowed us to process thousands of events per second, detect anomalies in under 10ms, and store results in a blockchain ledger without bottlenecks.

Why Blockchain? 🔗

Security is not just about detecting threats — it’s about proving that events were recorded faithfully.

By using blockchain, every event Asguard detects is hashed, timestamped, and recorded on-chain, making it impossible to alter without detection.

Tech Stack ⚙️

Backend: Node.js + Express
Database & AI Engine: Redis 8 with RedisAI, RedisJSON, Streams, Pub/Sub, RedisSearch
Blockchain Layer: Ethereum-compatible network for immutable storage
AI Models: Anomaly detection trained in Python, exported to ONNX, run inside RedisAI
Security: Role-based access control, JWT authentication

The Future of Asguard 🔮

Integrate federated learning to continuously improve AI models without centralizing sensitive data.
Deploy on edge devices for on-site, low-latency protection.
Expand blockchain integration for multi-party event verification in supply chains and government networks.
