Blockchain-Based Edge Computing IoT Architecture

The blockchain based edge computing architecture consist of three layers given as : IoT representation layer, Middleware, and blockchain.

A three-layer annotated architecture :

• The first layer replicates edge network containing different IoT devices, connected via internet. The user interface enhance visualization among IoT devices.
• Second layer facilitates in connection between layer 1 and layer 3, by providing data transport.
• Third layer consist of blockchain, which provides security, immutability, and privacy via decentralized data storage.

Proposed overall architecture :

• For layer 1, EdgeX Foundary , an open source IoT edge computing platform is used.
• For layer 2, Microservices & Apache Kafka is used.
• For layer 3, Hyperledger Blockchain network is used.

Guide Through:

• To set up layer 1 follow : EdgeX Foundary
• To set up layer 2 follow : Microservices, and Apache Kafka
