Unless you’ve been living under a rock, you’ll likely have heard of Web3. Web3 is broadly hailed as the future of the Internet, and Web3 apps have been all the rage lately. However, what is Web3, what improvements will it bring for users, and how can developers build Web3 apps and dApps? This article breaks down everything you need to know about Web3 and how to work with Web3 as a developer.
The Internet, or the Web, has changed dramatically through the years. With the advent of Web3, we’re on the cusp of the next Web breakthrough. While Web1 was a read-only web, and Web2 was a read-write web, Web3 instead promises to offer an unmediated read-write web – in short, a decentralized Internet.

Generally speaking, Web2 content dominates the Internet we all know and use today. Although the World Wide Web has come a long way from its inception back in 1989, it still faces issues. Specifically, it’s relatively centralized, and a few large companies – including Google, Facebook, Amazon, etc. – control a lot of people’s data. Web3 holds the keys to solving a long list of Web2 issues like this. To name a few, Web3 enables greater privacy, boosted transparency, eliminates intermediaries, facilitates data ownership and digital identity solutions.
All of this amazing Web3 functionality is based on blockchain technology. So, what’s holding Web3 apps back from going mainstream? Well, developing Web3 applications, or dApps, for this decentralized Internet is still relatively complex and time-consuming. Nevertheless, this is now finally solved when you use a service like Moralis to build serverless Web3 dApps! Moralis gives you access to fully managed, infinitely scalable Web3 backend infrastructure – so you can start building for Web3 today!
So, what exactly is Web3? Even if you might be unfamiliar with what the term refers to, you’ve probably come across it before. In layman’s terms, Web3 is widely understood as the third – and latest – ”phase” of the Internet. Roughly every ten years so far, the Internet has entered a new phase – going from Web1 to Web2 to Web3. Interestingly, however, there is no single controlling entity behind these phases or any universal line for when the Internet crossed over from being Web1 dominated to becoming a Web2 web. However, these different periods are characterized by the nature of Internet content. Put simply, the three stages of the internet can be summarized like this:
- Web1 – Static
- Web2 – Dynamic
- Web3 – Decentralized
The first phase of the Internet, Web1, was mainly about providing online content and information. As such, Web1 was largely static and practically only allowed users to read information.
The introduction of Web2, which is generally associated with the rise of social media platforms, was instead largely about interactivity and ”frontend” usability. Web2 eschewed the Internet’s previously static nature and saw the web become dynamic, allowing users not only to consume or ”read” information but also to create it themselves or ”write” information. However, this more participatory Internet also created issues, namely placing personal data in the hands of those running the main digital platforms.
Web3, on the other hand, aims to solve this by going from a dynamic to a decentralized Internet. Furthermore, in Web3, data isn’t owned by centralized entities – rather, it is shared. Moreover, Web3 focuses on improving back-end functionality, much like Web2 saw a focus on front-end functionality. A marquee feature of the Web3 era is also the emergence of dApps, or decentralized applications, which could supersede traditional applications.
What are dApps and Web3 apps?
No conversation about Web3 could be complete without the mention of dApps. In short, dApps, or decentralized applications, are the backbone of the Web3 revolution. Web3 promises to make the internet a more decentralized place, and this extends to the type of applications used in Web3. The terms ”Web3 applications”, ”Web3 apps”, ”decentralized applications”, ”dApps”, or ”Web3 dApps” are all largely synonymous. They all refer to the decentralized, generally blockchain-based applications that are a part of Web3.

So, what is Web3 apps? One integral part of many dApps or Web3 apps is so-called ”smart contracts”. Those of you with experience in blockchain technology will likely be familiar with the concept of smart contracts. Smart contracts are essentially self-executing software agreements, pieces of code that run on a blockchain like the Ethereum blockchain. These automatically ”run”, or execute when a relevant set of terms are met. As such, these ”contracts” can automatically verify and perform a transaction between different parties.

How to Integrate Web3
One of the most important challenges after answering “what is Web3?” is how to integrate Web3 advancements into your apps. Any developer with a bit of foresight will naturally want to develop a Web3 app – however, this has previously been hard. The main pain point of Web3 development has traditionally been manually setting up a Web3 backend. Not only is this a complex task, but it is also time-consuming and prohibitively expensive. As such, a lot of developers have had to settle for developing a Web2 app. However, with Moralis, it becomes easier than ever to develop a Web3 application!
Whether you want to know how to integrate Web3 with an existing idea or application, you just want cross-chain support for your dApp, or want even more content answering “what is Web3?”, be sure to use Moralis!
Truly Decentralized Internet with IPFS
Moralis packs a lot of different Web3 features in order to let you build apps for a truly decentralized Internet. For example, Moralis supports the InterPlanetary File System, commonly known as IPFS. So, what is IPFS? We’ll go more in-depth on this in a future article, but generally speaking, IPFS can be understood as a distributed peer-to-peer file-sharing system. As simply as possible, IPFS does not access the Internet from a single central server or through URLs. Rather, it accesses content from peers in the IPFS network around the world. Different devices that use IPFS act as nodes in a large distributed network, enabling you to access content from local nodes rather than remote servers. What’s more, IPFS uses ”content addressing”, which means IPFS does not look for something’s location; rather it looks for specific content.
IPFS comes with a lot of benefits for building Web3 apps and decentralized applications. For example, it makes the Internet more resilient, as IPFS does not fetch content from a single centralized server. This makes it harder to censor the Internet or prevent sharing of information. Moreover, this type of decentralized network can also lower latency dramatically. When you get content from a local node rather than a distant server, load times are naturally shorter.
Best of all, Moralis supports InterPlanetary File System (IPFS) out of the box. As such, you can easily build an application that takes advantage of IPFS’s distributed network. You do not have to worry about things like configuration issues, as Moralis natively supports IPFS. Take a look at our Moralis IPFS documentation page to see how you can leverage our IPFS support.
What is Web3 vs. Web2?
It is hard to overstate how important the advent of Web3, sometimes known as ”the Semantic Web”, will be. It is undeniable that the Internet is moving towards this unmediated, read-write version of the web. However, the only thing that is unclear is how quickly Web3 will become the dominant form of the Internet. Just as the Internet did not shift from the read-only Web1 to the read-write Web2 in a day, this change will take years.
Choosing between building for Web3 vs. Web2 should, therefore, not even be a discussion at this point. The current state of Web2 is an oversaturated market that is riddled with technological limitations. Web3, on the other hand, has nearly limitless potential and is ready for new projects. This presents you with a remarkable opportunity. The fact that Web3 is still in its infancy means you can get in at the ground level. You will not be able to build the next ”Facebook” for Web2 – that’s just Facebook and already exists. However, you might be able to build the next ”Facebook” of Web3.
It is virtually impossible to create a revolutionary Web2 website or app today. The market is simply too saturated with established near-monopolies, such as Facebook and Google. However, roughly 15 years ago, when the Web1 era was drawing to a close, this was far easier. Just think about the various social networks like Twitter, Instagram, Facebook or YouTube, that we now take for granted. As the Web2 era similarly draws to a close, you are perfectly positioned to come up with a successful Web3 app, or dApp. You will never again get the chance to create a Web3 app as early as today. Be sure to take your chance and join in the coming Web3 startup gold rush!
