dApps also know as Decentralized Application that works on a blockchain network computers rather than waiting for a single computer. It also protects it's users privacy. The absence of censorship makes the development flexible. dApps are not controlled by anyone.

Explain the working system of dApps?

Decentralized Application make use of a smart contract that runs on a decentralized system. The Smart Contracts are used for app logic and 5hey also make use of Ethereum blockchain to store data. A smart contracts has a lay down rules on blockchain that are visible for users to see and obey the rules. The Smart Contracts are like a vending machine that can holds may funds like the Ethereum account and also it gives access to codes to moderate agreement and transactions. You cannot be able to make any changes once the dApps are distributed on the Ethereum network. Due to dApps are controlled by logic written into the contracts, makes them a decentralized apps.

What are the differences between dApps and other applications

The main difference between a dApps and other Apps is the lay down principle of Decentralization. Other apps are are controlled by the centralized system but the dApps works on the P2P blockchain network.

  1. dApps are Trustable: Users are in controll of their own data and information making dApps more Trustable than any other Apps. But centralized Apps are more user friendly.

  2. Cost of Development: Unlike centralized Apps that will have to consider the cost of maintenance, cloud fees and so on. But dApps developers don't have to consider such things due to it cost are as follow development, deployment and upgrade.

  3. Usage Cost: In dApps it's users have to pay a little amount of money unlike the centralized Apps that are free to use. Sometimes users wonder why it is so . It is due to the the more complicated is the app the more the fees increase.

  4. Security: Iris quite obvious that dApps are more secured than the centralized Apps. Because of its Decentralized nature, makes them more secured and store records that not be changed and tempered.

  5. Speed: The centralized Apps are quite slow. It is said that they can transact 15 transcations in a second. But in the case of dApps it's Scalability is up to a thousand transactions per seconds in time to come. You can see that there are no sign of slow moment in dApps.

Explain the advantages and disadvantages of dApps

Everything we do on the blockchain has their Advantages and Disadvantages. dApps are not left out below I will be starting with the advantages of dApps.

Advantages

  1. Easy To Control: Applications built on blockchain are always designed to connect other trading partners not withstanding if it is centralized. The organization involve must trust the host that is controlling the connection. But in dApps this problems are not found because it's pattern gives access to each party to run the app and don't need to trust a third party.

  2. Easy To Develop:Decentralized Apps make use of compound protocols to attain consensus. The more compounded it is, the greater abstraction that is made available for developer that are looking forward to apply specified business strategy.

  3. Safer Data: Decentralized Applications works on a shared database which duplicate information that is stored across all other nodes. This implies that, if a single node is hijacked, it doesn't stop the organization's ability to examine it's important data.

  4. Transparent Data: unlike the centralized applications that require's their users for their own data, dApps don't ask their users for their data due to dApps are on a public blockchain and the information cant be hidden.

  5. No Loss of Data: Information are automatically stored pamanently once it is added to the blockchain. This shows that dApps are more resistant to restriction.

  6. Open Source: All codes on dApps are transparent and can be views by anyone that wants to confirm what the developer's claims on what it does.

Disadvantages

  1. dApps Infra is Difficult to Maintain and Develop: Every user on dApps needs to update their nodes software failure to do so, makes maintenance, debugging and updates harder on the system due to dApps runs in a complex environment.

  2. Slow Speed: Sometimes it takes dApps time load and also it takes time for payments to process.

  3. Lack of User Experience: In this case the dApps don't function as centralized app so it is hard to have the best user experience. For instance you can easily remember your username and password in centralized system but it is not so in dApps where you have your public or private key to cram off hand.

CONCLUSION

Blockchain has come to stay and it is changing from time to time. It has brought ideas to so many industries and makes industries to have new services and capabilities. Decentralized Applications are one the invention of the blockchain. It has offer open-source software that is well secured for users and business. As dApps keeps growing, more innovation are been introduced and not only that it is always necessary to know and understand the good and bad of each apps and technology that we make use of.
