Secure and Intelligent Real-Time Price Aggregator with Predictive Analytics and a Blockchain-Based Trust Model

A secure and intelligent real-time price aggregator with predictive analytics and a blockchain-based trust model.

A secure and intelligent real-time price aggregator with predictive analytics and a blockchain-based trust model. This reference project walks through the whole job, from the problem and the design to the build and the evaluation, so that a developer can study how it works, run it and extend it.

It suits learners who want to build decentralised applications: designing smart contracts, testing them, connecting a front end through a wallet and reasoning about security and cost.

The main parts are real-time processing of incoming data, a dashboard with charts and filters, security and privacy controls such as encryption and access control, smart contracts for the core rules, and a front end connected through a wallet. The reference build uses Apache Kafka, Solidity, Ethereum, Hardhat, and Web3.js, with a clear project structure, setup instructions and sample data so that it can be run and extended.
