A blockchain is an advanced technology that can power over a decentralized network. The authors bring it up to design the autonomous transaction system for e-commerce applications; because of the dramatic increase in IoT devices, communication between physical things is enabled. This brings more efficiency and accuracy, which benefits the outsiders while human interaction reduces. There is a big challenge in data storage after payment in the e-commerce application. Blockchain presents an appropriate platform for the distributed data storage; it also protects the data from outsiders. The authors create blocks that check and record each transaction that took place in the e-commerce application. Blockchain is going to protect the user's privacy from outsiders/banks that are being violated. The authors deliver this research in this paper in terms of the method with detailed design and full implementation. The system captures the user data, processes it, and gives a visual representation of the processed data.

The present paper breaks down the most conspicuous savvy network functions from the Web of Things execution point of view. A Savvy MV/LV substation is proposed as an answer that will deal with astute activities, like constant checking, control, and framework the board, in an effective way. Notwithstanding, these incredible advantages it also includes some major disadvantages. With quickly advancing Web of Things network, keeping up with digital protection and security will introduce an extraordinary test from here on out and answers for proficiently conquer these shortcomings ought to be additionally explored and created.

As an ever-increasing number of gadgets are getting associated with the Internet, the following consistent advance is to involve the World Wide Web and its related innovations as a stage for brilliant things. This paper proposes a web-based engineering model for the execution of Internet of Things. An execution situation for home systems administration is likewise talked about. The concept of smart home with the integration of networking using IoT enabled cloud computing to it, by embedding intelligence into sensors and actuators, networking of smart things using the equivalent technology, facilitating interactions with smart things using cloud computing for easy access in different locations, increasing computation power, storage space and improving data exchange efficiency.
