BLOCKCHAIN TECHNOLOGY : E-COMMERCE ONLINE APPLICATIONS

In existing E-commerce application all customers and product details will be stored and managed in single centralized server and if this server crashed due to too many requests and or if server is hacked then services will not be available to other customers and to overcome from this problem we are migrating E-commerce application to Blockchain which will maintain data at multiple nodes/servers and if one node down then customers can get data from other working nodes. Another advantage of Blockchain has inbuilt support for data encryption and immutable (data cannot be alter by unauthorized users) and it will consider each data as block/transaction and associate each block storage with unique hash code and before storing new records Blockchain will verify hash code of previous blocks and if all nodes block verification successful then data is consider as secured. To implement this project we have used Blockchain Ethereum with Truffleto store E-commerce data and Blockchain cannot store images so we are storing products images inside IPFS (interplanetary file storage) server and this server will store image and returned hash code of stored image.
