A blockchain is a publicly available, distributed ledger that keeps track of the transactions that have occurred within it. When we talk about the block chain, we are referring to the complete history of all transactions on the bit coin network since its inception in 2009, which currently amounts to around 300 gigabytes of data stored on thousands of computers around the world. Although this might seem like an unnecessarily convoluted solution to managing records, there are many reasons why block chain are becoming more and more popular as a way of handling data storage and transfers.

Introduction

We live in an era of decentralized applications. The web as we knew it is gone, and with it goes the centralized authorities that govern our data. In its place, new systems are emerging that trade control for trustlessness, privacy, transparency, and autonomy. These decentralized applications (or DApps) are built on top of a technology called block chain–a shared ledger of transactions maintained by a network of computers around the world. DApp have remained everything from social media to online shopping; in time, there will be no limit to what people can do with this technology.

What is a decentralized application?

Decentralized applications are programs that are open source, which means that anyone can look at the code behind it. They also provide a platform for developers to create new services. On a decentralized application, data is stored in different places on computers around the world. This is what makes them so difficult for hackers to attack. This also means that you don’t need centralized servers to run them, which reduces costs for both users and developers. The decentralization of applications has been made possible by blockchain technology, which was created in 2008 by Satoshi Nakamoto as part of a peer-to-peer electronic cash system called Bit coin.

What is the block chain?

In order to understand what a blockchain is, it is important to understand how a traditional database functions. A database will have three components, a client, a server, and data. The server usually stores the data which is replicated on each of the other servers. The data may be replicated asynchronously or synchronously. If there are two servers in an asynchronous replication mode, any changes made by one server will not be reflected on the other until after some time has passed. In synchronous replication mode, changes made by one server will be immediately reflected on all of the others with little delay.

What are the benefits of using a decentralized application?

If you are interested in learning more about decentralized applications or want to learn how to develop one, there are a few things that you need to know. What is a decentralized application? A decentralized application (or DApp) is an app that relies on data being stored on a road to web3 rather than on a central server. In order for this type of app to work, it needs access the blockchain which provides it with its data. If your phone doesn’t have access to the internet then it will be impossible for these apps (even ones you might not expect) such as social media, news feeds, e-commerce sites, etc.
