The dApp-ening: The rise of Decentalised Apps

If you've done any research into the blockchain in the past few years, you've probably come across the phrase "dApp" and wondered what sets it apart from the apps you use on your phone, computer, and the increasingly diverse range of other devices on which apps are appearing. You might be pleasantly surprised by the creative uses that developers have found for blockchain technology.

ELI5: what is a decentralised application?

Apps built on top of the blockchain technology are known as decentralised applications (or dApps for short). Common components include a smart contract at its heart, which manages the app's essential logic, and more conventional software to facilitate user interaction with the contract in the same way they would with a conventional web app or application.

As developers explore the possibilities of this technology, DApps are being developed for a broad range of purposes, from the purely entertaining to the purely practical to the purely abstract. In addition, dApps may become more distributed than your average app thanks to the blockchain (or, in some circumstances, a P2P network solution) they employ.

By using some of cryptocurrency's most potent features, decentralised applications (dApps) may give users access to robust resources without requiring them to rely on a central authority or establish any kind of trust. This has enormous implications for the realms of possibility.

Using DApps Has Its Benefits

dApps provide several benefits for those who place a premium on anonymity, data ownership, and decentralisation of transactional and interpersonal processes. Furthermore, decentralised applications (dApps) can be resistant to censorship and cross-border in a way that gives more people access to resources that would be inaccessible to them otherwise.

Due to their decentralised structure, DApps have the ability to circumvent many of the issues that plague conventional organisations and programmes. The more a dApp depends on blockchain technology and uses smart contracts for essential functioning, the less likely it is that it will experience downtime. If a dApp's smart contract can supply all of the app's core functionality in the event that the blockchain hosting the contract goes down or otherwise fails, then the app can be extremely stable.

Most decentralised applications (dApps) are made available to the public in the form of open-source software, as transparency is a crucial factor for many people considering about using them. Software that is open-source (or at least has key components like contracts that can be accessed by anyone) is inherently more trustworthy since it allows for more visibility and auditability.

Inadequacies of Dapps and Ways to Fix Them

You probably don't give much thought to an app's inner workings when you use it, but that's not always the case when it comes to decentralised applications (dApps). There has been a lot of progress made in the direction of enhancing the user's experience, but there is still a long way to go before things seem completely natural. The fact that a blockchain is powering an app doesn't imply you need to know about it any more than you need to know about the databases, programming languages, or frameworks powering the apps you use every day.

Many current dApps still struggle with centralisation. An example of this would be a decentralised application (dApp) that relies significantly on a frontend hosted by a conventional hosting provider. Though "decentralisation" is in the title, in practise it is more of a grey area than a strict dictum. Even though it might be difficult, many dApps could benefit from doing a better job of reducing their reliance on external resources.

Bugs that cause complete loss of cash are a major threat to decentralised applications. Many dApps are designed to facilitate transactions of some kind, and as a result, they come to exert considerable influence over the value exchanged. Let's say the smart contract contains a vulnerability, for instance. Since this isn't a simple issue to fix after a contract has been released, and since it may be far more severe if it's abused before developers are aware of the risk, it's unlikely that this will be addressed anytime soon.

Additionally, while the decreased reliance on human involvement that many dApps offer is undeniably beneficial, it does necessitate extra caution when dealing with highly consequential transactions, since there is no one to turn to for help in the event of an error. In addition, even if you do manage to get in touch with someone, it may be too late to undo the damage. Despite the fact that this is par for the course when dealing with cryptocurrencies, it presents difficult UX/UI challenges for dApp developers who need to guarantee that their customers are making proper and secure use of their goods.

DApps and Their Obstacles

  • Due to bugs, money may be lost forever or become inaccessible.

  • In crypto, mistakes might be irreversible.

  • There are several dapps that are still in the early stages of development.

  • After a contract has been deployed, upgrades might be challenging.

  • Blockchain technology can provide considerable difficulties in terms of user experience and user interface.

  • Some dApps may require widespread uptake for maximum efficiency.

  • Storage, transaction, and speed constraints on par with those of the blockchain

To what blockchains may DApps be deployed?

While dApps and smart contracts were formerly rarities, they are now spreading at a remarkable rate. Due to the open-source nature of many decentralised applications (dApps) and the fact that many major smart contract-capable blockchains are EVM (Ethereum virtual machine) compatible, a wide variety of apps are being ported from one chain to another, and new, even more experimental variations are appearing. EVM compatibility also makes it easy to port over small projects from one chain to another.

It is not always the case, however, since some blockchains take a different approach and use their own proprietary or prefered languages for writing smart contracts, which impacts dApps on those chains. Although Solidity (Ethereum's smart contract language) is gaining traction, it is not the only approach a blockchain may take when incorporating smart contracts. Cardano, for example, has decided to write all of its code, both on-chain and off-chain, in the surprise choice of Haskell.

Newer blockchain projects are seeking to set themselves apart by delivering unique features, while bitcoin continues to dominate the market for value storage and provides an extremely safe mechanism to trade money. In this respect, "smart contracts" have gained considerable traction. Consequently, the question that should be asked is not which blockchains enable smart contracts and dApps but rather, which don't.

Digital Application Development in the Future

The future of dApps is likely to be more than a little unexpected, given the significant increase of dApps and the probable improvements in usability that will follow with increased testing. Over the next few years, we can expect to see some truly remarkable accomplishments in terms of both what dApps can do and how effectively they do it, bolstered by expanding layer two technology with fast and inexpensive transactions, expanding research, and the many other blockchain innovations on the horizon.

The future of these modern applications has a lot of potentials to wow, as interest develops in ideas like the metaverse and crypto continues to surprise even the most obstinate proponents.
