NeoLine Talk _ What is the so-called "DApp"?

With all the wallet, you will discover a variety of DApps really appealing to your attention.

 The blockchain browsers we released within the last issue belong to DApps, so what are usually they? How could it be different from a normal app?

![NeoLine Talk | What is the so-called "DApp"? ]() DApp had been proposed by Ethereum founder Vitalik Butlin and his partners in 2015. The initial intention was to create everyone's blockchain by means of DApp, that's, on the blockchain system Create decentralized apps that incorporate non-tamperable smart agreements to save lots of manpower and money. **Merely put, it is an app with wise contract additional. ** DApp and App are usually somewhat similar, but there are some distinctions. App We all have been familiar with, it is an app installed on a smartphone. The Series we often make use of can be an app. *DApp is D+App, D is the initial letter of decentralization "decentralization", DApp is a blockchain-based application, so it gets the characteristics of decentralization, openness, transparency, and non-tamperability. *And how can you realize these characteristics?

   ![NeoLine Talk | What is the so-called "DApp"? ]() Decentralization

Traditional apps require a team to operate. If the group is gone 1 day, the server will shut down and you will no longer have the ability to log in to the app.

For instance, you published a piece of information on Weibo. This information bombarded the Weibo system, and it had been paralyzed. At this time, customers can only watch the Weibo server after it is repaired, but after the maintenance, Weibo judges yours. News is unlawful info and deleted directly in the background. This is also a drawback of centralized apps.

    ![NeoLine Talk | What is the so-called "DApp"? ]() Unlike DApp, this is a distributed application in line with the blockchain and has the characteristics of decentralization.

Put simply, in comparison to traditional apps, DApps do not have a central point, which means that DApps will not stop service due to the downtime of the central point server, so there will be zero network breakdown.

 Even though the group that created this DApp is gone, so long as the blockchain continues to be (the node continues to be), we can still use this DApp, and it is likely that it'll be maintained by a community that has achieved a consensus. Exactly like Bitcoin, although we don't know who its growth team is, and there is absolutely no fixed group operating and sustaining it, Bitcoin continues to be in an unshakable placement. From another viewpoint, the operation and maintenance costs of DApps will undoubtedly be greatly reduced through distributed nodes.

Open and transparent

You will have a lot of lucky allures the App, but most people find that they're not really the "lucky guy".

We often question whether there is a black-box operation on the system, such as if the random selection is actually random, whether all of the prizes in the case have been issued, and what is the probability of winning.

   ![NeoLine Talk | What is the so-called "DApp"? ]() However in DApp, these can be found through the block internet browser. The rules of the lottery will undoubtedly be written in to the smart contract and stored on the blockchain. In this manner, we will clearly know the probability of the lottery.

At the same time, we can also check the true winning situation. When all of this data is open and transparent, we've no cause to question the fairness of the lottery.

Can not be tampered with

On the blockchain network, if someone really wants to modify the info, more than 51% of the nodes need to agree. This means that no one can quickly tamper with the info, and exactly the same holds true for DApps.

For example, during the past few many years, a casino game called Legend has exploded, and a Dragon Sword could be sold for tens of thousands of yuan. Provided that the game manufacturer changes the code, it could produce a large number of them, earning lots of money every moment. In a centralized system, getting privileges is just that wayward.

The blockchain game DApp is made on the underlying blockchain growth platform. The rules of the game are usually that programmers write smart agreements and store them on the blockchain, which cannot be altered by developers.

The player's equipment and rewards are all executed based on the smart contract, and the ownership belongs to the player. As a result, on the blockchain system, the non-tampering feature ensures fairness to a certain degree.

   ![NeoLine Talk | What is the so-called "DApp"? ]() In a nutshell, we can summarize DApp as: DApp = front-end + wise contract.

●Not really controlled by a single entity, since it does not have a central stage;

**

 **

● No need to pay out for the third party, because there is no central stage trust problem;

**

 **

● Will not stop the services because a solitary machine is down since it is not running on any centralized server;

**

 **

● There is no delay inside transactions because of the use of smart contracts.

Of course, the relationship between DApp and App isn't a substitute for each some other. Because App provides been really mature after many years of development.

With regards to the existing situation, DApp even now has a good way to set off in terms of the number of applications and the number of users. You can find reasons for the bear market, there are also reasons for the higher threshold, and there are multiple reasons for the lack of individuals in the blockchain circle.

Nonetheless it is undeniable that blockchain technology has taken us a huge space for creativity, and we need to give DApp additional time and space for it to grow.

I really believe that as the functionality of the underlying blockchain continues to boost, there will be more and more practical and easier-to-use DApps later on.
