Decentralized Applications (dApps)_ Examples, Advantages, and Disadvantages.
1. Decentralized Applications (dApps):
Examples, Advantages, and
Disadvantages
Intensive decentralization is practiced with the aid of blockchain
technology. A decentralized or distributed application does not run on a
single server but instead utilizes the excess processing power of
thousands of computers worldwide and is controlled by business
automation software that ensures a function can only be executed if a
specific parameter is met.
Note, however, that decentralized applications need not run on a blockchain
network; they can also run on a special type of peer-to-peer (P2P) network
2. that is not a blockchain. Tor, BitTorrent, Popcorn Time, and BitMessage are
decentralized applications that function on a P2P web.
Let's understand the meaning of decentralized applications and simplify
the concept for you.
What are Decentralized applications?
Decentralized applications are software that interacts with the blockchain,
which records the status of each network participant. Today, the user
interface of decentralized applications is identical to that of any other
website or mobile application. A smart contract represents the core logic of
a decentralized application.
Smart contracts are blockchain components that process data from
external sensors or events and aid in managing the state of all network
actors. Typically, they're used to automate the execution of a contract so
that all parties can know the outcome immediately, without the need for
intermediaries or time-wasting delays. In addition, they can automate a
workflow by initiating the subsequent step when certain conditions are
met.
The front of a decentralized application represents the user interface, while
the backend represents the business logic. One or more smart contracts
that interact with the blockchain represent this business logic.
3. Photos, videos, and audio files could be stored on decentralized storage
networks like Swarm or IPFS, which could also host the front end.
Traditional Web applications render a webpage using HTML, CSS,
javascript, or a similar language. This page communicates with a
centralized database containing all data.
A traditional webpage will use an API to process your data and other
necessary information stored on their servers to display it on the page. This
is the primary distinction between centralized and decentralized
applications. Low-security user IDs and passwords are used for
identification and authentication because personalized data is stored on
the service provider's server.
Decentralized vs. Centralized applications:
One company owns a centralized application. The application software of a
centralized app is stored on one or more company-controlled servers. As a
user, you will interact with the application by downloading it and then
sending and receiving data from the company's server.
A blockchain or peer-to-peer computer network is utilized to run a
decentralized application. The user will pay the developer a cryptocurrency
fee to download and use the program's source code. A smart contract is a
4. source code that enables users to conduct transactions without disclosing
personal data.
Top 7 dApps:
Bitcoin was the first decentralized application, allowing anyone in the world
to download open-source code, join a blockchain network, and verify
transactions using a mining algorithm in exchange for digital currency.
Depending on the blockchain platform, dApps are used by a small and large
blockchain dApp development company to track and trace goods as they
travel the globe and to enable cross-border financial transactions without
the need for an intermediary such as a central bank or clearinghouse.
Here are the top dApps available in the market:
1. Brave:
Brave, a web browser with nearly 9 million active users, has recently
emerged as a formidable competitor to Chrome. Brave is attempting
to flip the online advertising model by putting consumers in the
driver's seat. The app creates a new value metric in advertising, where
"consumer attention" is valued more than unverified page views or
clicks.
Brave has received more attention than most alternative browsers,
partly because one of its co-founders was a key figure in the
5. development of Mozilla's Firefox and partly because of its unusual —
and some would say parasitic — business model. The browser's
developer, Brave Software, is one of the more recent entrants in the
browser wars, having debuted the browser in January 2016. After
leaving Mozilla, Brendan Eich, the creator of JavaScript and a
co-founder of Mozilla, co-founded the company.
Chromium, an open-source project maintained by Google and others,
serves as the foundation for Brave. Brave utilizes Chrome's backend
technologies, such as the Blink rendering engine and the V8
JavaScript engine.
2. Golem:
Golem is a decentralized application (DApp) that aims to establish a global
market for surplus computing power. The project's objective is to create a
supercomputer that can be rented by anyone, anywhere in the world, by
combining the power of PCs and data centers. Instead of relying on a
centralized server farm, the initiative distributes the computational load
among "Providers" willing to rent their computers for computing time.
In exchange for GNT tokens, these suppliers can offer their resources. The
project has great potential because it allows for the decentralization of the
6. rendering process, which is much faster and cheaper than centralized
solutions.
3. TRACEDonate:
Regarding charitable contributions, the "donation sector" lacks
transparency and accountability. TRACEDonate's identity management
platform enables transparent and traceable cross-border remittances and
donations.
The dApp created by AID: Tech connects charitable organizations, donors,
and recipients. According to Piekarska-Geater, the organization hopes to
provide donors with peace of mind by ensuring that their donations are
used for the intended purposes, such as purchasing food or utilities rather
than alcohol, by those in need.
Using blockchain, the identity of the charitable organization and the
recipient of a donation is verified. Because the funds are stored in an online
digital wallet, the donor can monitor how the money is spent. Donors can
also specify how the funds will be used, such as for medical aid, food, or
other emergency supplies.
4. Circulor:
Circulor is one of the most widely used applications for decentralized
supply chain traceability in the electric vehicle and electronics
industries. It proves that the raw materials used in the latter's
7. production were ethically and sustainably sourced. Circulor is a
track-and-trace platform that enables users to secure deliveries,
manage payments, and verify the origin of raw materials, among other
things. Circulor is designed to handle the complexities of the real
world.
Dapps have emerged with distinctive properties that enable
stakeholders to invest in developing decentralized applications, giving
them the potential to become self-sustaining resources.
Based on their popularity, DApps for various purposes, such as
payments, storage, and cloud computing, are anticipated to
outnumber traditional apps eventually. As Blockchain becomes
indispensable, numerous existing methods will become obsolete.
Although it may seem implausible now, services such as banking will
soon adopt Blockchain and operate on trustless, self-sufficient, and
decentralized networks. Large corporations strive in this direction to
secure their position within the Blockchain ecosystem.
5. Aragon:
Aragon is a significant addition to the DApps collection. It is possible to
create and manage decentralized organizations on the Ethereum
Blockchain-based platform. The Aragon Foundation administers the Aragon
open-source project.
8. The project's objective is to eliminate the need for human commerce by
enabling individuals to manage entire businesses and organizations using
the Ethereum Blockchain. Individuals can use the platform to establish and
manage decentralized autonomous organizations (DAOs). ANT, the
platform's token, grants voting rights for future product development
decisions. Any organization, business, non-profit, or foundation can utilize
the DAO model developed by Aragon. It is anticipated to increase the
transparency and effectiveness of governance in such organizations.
Aragon also helps to eliminate unnecessary third parties by replacing them
with smart contracts based on the Ethereum blockchain. By removing
geographical barriers and bureaucracy, the program promises to create an
incredibly simple digital jurisdiction for everyone.
6. KYC-Chain:
Businesses use his app to verify customer identities and streamline the
onboarding process by KYC regulations. Through partner sanctions and
watchlists database spanning over 240 countries, it can ascertain
individuals, corporations, and institutions for criminal or prohibited
activities in real-time.
KYC-Chain enables users to store their certified identity details on-chain
and control public access to their credentials by offering public keys when
a permit is required, courtesy of a self-sovereign identity dApp developed
by SelfKey, a partner company.
9. Users can pay for individual services such as accredited investor checks,
crypto funds screening, ID verification, and document authentication
through the decentralized application. Users can use the service to
compare client crypto wallet spending to known risk indicators and comply
with anti-money laundering regulations.
7. Prism:
Prism is an initiative of ShapeShift built on the Ethereum Blockchain. It is a
decentralized and unreliable market for asset portfolios. It creates bespoke
market portfolio management tools using executable distributed code
contracts, or EDCCs. Prism enables anyone to invest in other
cryptocurrencies.
Prism eliminates the need for third parties and the time-intensive
maintenance of multiple private keys and wallets. Because the project is
built on Ethereum smart contracts, it is unnecessary to remember multiple
exchange passwords and keys. In addition, it features an interactive user
interface that displays an individual's investment portfolio in real time and
keeps track of everything.
Here are some of the advantages of decentralized apps:
1. The program's core is dApps' capacity to safeguard user privacy. To
use the app's features, users of decentralized apps are not required
to submit personal information.
10. 2. DApps use smart contracts to facilitate transactions between two
anonymous parties without requiring a central authority.
3. According to proponents of free speech, dApps can be designed as
alternative social media platforms. A decentralized social media
platform would be impervious to censorship because no single
participant on the blockchain could delete or prevent the posting of
messages.
4. Ethereum is a flexible platform for developing new dApps, allowing
developers to concentrate their efforts on discovering novel uses for
digital applications. This could expedite the deployment of dApps
across multiple industries, including banking and finance, gaming,
social media, and online shopping.
Disadvantages of Decentralized applications:
Here are the disadvantages of decentralized applications:
● As decentralized applications are still in their infancy, it is
experimental and subject to several unknowns. There are concerns
regarding the scalability of applications, particularly if an application
requires a large number of computations and causes network
congestion by overloading a network.
● Another concern is the ability to design a user-friendly interface.
Most users of traditional centralized institution-developed apps
anticipate a level of usability that encourages them to utilize and
interact with the app. To convince users to switch to decentralized
11. applications (dApps), developers must create an end-user experience
and performance comparable to that of well-known and established
programs.
● Another limitation of decentralized applications is the difficulty of
modifying code. A deployed dApp will almost certainly necessitate
ongoing modifications, either to improve or fix bugs or security risks.
According to Ethereum, it may be difficult for developers to make
necessary updates to dApps because data and code published to the
blockchain are difficult to modify.
