Storing data in a database is an integral part of any software application. Regardless of the control of the database there is a master control of that data. Blockchain technology stores data in chunks within a blockchain network. As a result, as long as a node is synchronized with the network, they get a copy of the data in the chunk. Therefore, there is no specific data master in this technology.In this tutorial, we'll write a smart contract (which I'll explain further) to keep the user data o

Create a private repository for docker and a private repository for docker Thanks to the network speed and the performance of the Greater China LAN, the image download speed in DockerHub is very slow. Even some domestic image warehouses do not feel very fast. Therefore, it is necessary to build an image repository locally or in a place that we can access quickly (your own ECS. With such a repository, we can
