A 2021 Guide to Dapps: What Are dApps?

Written by

Software programs known as decentralized applications run their backend code across a dispersed computer network. Standard applications, which are normally operated on centralized servers, stand in stark contrast to this. This affords dApps a number of distinctive characteristics and advantages over their centralized competitors, coupled with other blockchain-driven advancements. But even at this first stage of development, dApps have some problems.

The unique characteristics of decentralized applications (dApps), as well as the advantages they offer and the difficulties they must surmount if they are to genuinely contend with the centralized approach, will all be covered in further detail in this article. So,

Why do people use dApps?

As soon as we have a basic understanding of what decentralized apps are, we can go deeper into the aspects of this rapidly growing industry. Prior to distributed ledger technology, decentralized apps were widely used, and peer-to-peer platforms like the original Napster and BitTorrent had success utilizing peer-to-peer networks. However, the growing popularity of Ethereum and blockchain technology, in general, has given both the term “dApp” and the idea it stands for a boost.

Why Ethereum, then? Blockchain technology predates Vitalik Buterin’s creation by a substantial amount, as many blockchain protocols were already in use when Ethereum first hit the market. I suppose smart contracts are a simple solution.

As we’ve already covered on these pages, Ethereum was created as a multipurpose blockchain that can support and develop a variety of applications. In order to achieve this, Ethereum built a Turing-complete language called Solidity and utilized an antiquated idea that was adapted from the design of vending machines. Ethereum played a role in popularising the use of smart contracts for blockchain applications. Ethereum has maintained its position as the top platform for smart contracts and, consequently, decentralized apps despite the emergence of several prominent rivals.

Decentralized applications must use smart contracts in order to function. These self-executing algorithms provide the logic that makes decentralized apps work. Because a smart contract already enhances the backend functionality of the original blockchain technology, it is effectively a dApp. You can create something that resembles a traditional app but operates on a blockchain by combining that with a user interface that can communicate with the backend. Naturally, you can create a tonne of smart contracts to add more features and create programs with more complex logic.

What distinguishes centralized applications from those that are decentralized?

The question of whether we genuinely need dApps in the first place arises, given the prevalence of centralized apps and our familiarity with them. After all, the centralized approach is effective and, in some cases, may even be preferable to the decentralized one. And it’s true that a number of issues with the blockchain dApp development company still need to be fixed. Despite still being in the early stages of development, there are a few extremely important benefits that indicate the enormous potential of dApps. So let’s examine what dApps have to offer and how they compare to their centralized competitors.

Security

One area where decentralized apps excel is in this. “dApps,” or applications created on the DLT, provide a high level of security by design. The single point of failure issue that affects centralized server-based systems is not an issue for decentralized solutions built on the blockchain or other distributed ledger technologies. Additionally, because of the strong consensus mechanisms incorporated into them, blockchains and DLTs are particularly resistant to malicious attacks. The fact that data saved on DLT systems cannot be altered in any way is another important benefit of these systems.

Speed

One issue with the present crop of decentralized applications and blockchain platforms is this. All of this is a result of blockchain technology’s constrained scalability, which makes it challenging for most blockchain networks to process large amounts of transaction data concurrently. This usually results in network congestion, especially when dApp activity is high. One such instance is the 2017 launch of the online collectibles game CryptoKitties. The Ethereum network soon became overloaded as a result of the game’s sudden surge in popularity.

Cost

Using a blockchain network also results in increased expenses because of the scalability issue. Due to the need to pay miner fees in order to process transactions more rapidly, customers see large cost increases as a result of network congestion. Due to its extensive network usage, Ethereum, in particular, has a history of experiencing escalating gas prices.

One of the major goals for the blockchain community has been finding a solution to the scalability issue. For Ethereum, there are already a large number of effective Layer 2 scaling techniques. As the platform implements sharding and switches from proof-of-work to proof-of-stake, it is also going through a significant shift. These two improvements, which are also a part of the Ethereum 2.0 project, are meant to increase the scalability of Ethereum while consuming less power.

Openness

The fact that dApps are open and permissionless is one of their main advantages over centralized applications. There is no mechanism to limit access to a certain dApp because decentralized public platforms like Ethereum are not under anyone’s control. Decentralized apps do not impose content restrictions. This also entails, thus. When we take into account how the open nature of dApps will affect the sector’s development side, this point has even greater significance.

Developers can build on one another’s work and combine and recombine various components from multiple projects to create new kinds of applications and services because all dApps are, by nature, open source. This supports creativity and enables the area to develop and change in fascinating and usually surprising ways.

What use cases for DApps exist today?

In the blockchain industry, many different kinds of decentralized apps have already been created, and programmers are continually looking for new uses for the technology. This is a result of its ability to draw in and support talent relevant to innovation. The potential of dApps has already been demonstrated in a number of industries, including DeFi, enterprise solutions, gaming, digital collectibles, and others.

Financial independence (DeFi)

DeFi applications are, without a doubt, the most potential use case for dApps at the moment, having already produced a market with a current value of over $40 billion. By offering new means to borrow and lend money as well as by encouraging the development of cutting-edge financial services like liquidity mining, the quickly expanding DeFi business seeks to threaten traditional banking.

Business Solutions

Blockchain-based solutions have the potential to revolutionize a number of industries and enhance business expansion and productivity. Pharmaceuticals, healthcare, and supply chain management are a few industries where enterprise-grade dApps have already had an impact.

Digital collectibles and gaming

As was already mentioned, a game was the first dApp to experience widespread appeal. Since CryptoKitties’ launch, other initiatives in a similar field have made an effort to duplicate its early success. Games like Decentraland and Gods Unchained demonstrate that there is still a sizable demand for gaming dApps even though none of them have been able to achieve quite the same level of popularity. The potential of blockchain-based digital collectibles is further illustrated by the continued rise in non-fungible tokens.

Conclusion

Decentralized apps are still in their early stages, but blockchain technology has already established a compelling case for them. Additionally, as technology develops further, dApp development will expand, opening the door for the development of new dApp categories and more complex software. Decentralized apps appear to have a key role to play in our digital future, even though it is still unclear whether they will be able to surpass regular apps.
