For many people, it's still not clear what web3 is. But in reality, the list of existing and flourishing web3 projects is already extensive. Apps and protocols like Polygon, Harmony, or Axie Infinity attract not only enthusiasts, but also people who are joining web3 for the very first time. If you're interested but not yet convinced about the value of web3, take a look at this list which includes some of the most exciting web3 projects out there.
What are web3 projects?
Web3 projects rely on the fundamentals and principles of blockchain technology. They are decentralized and permissionless. They don’t require trust from the user or developer. They don’t steal value but instead they reward for participation, development, and engagement.
The scope of web3 projects is extensive. The list includes categories of apps and concepts like layer-2 scaling solutions, DeFi tools, stablecoins, NFT marketplaces, play-to-earn games, or interoperability protocols.
Then, how to choose the ones with immense potential? Even though it’s still difficult to predict the future of blockchain, dApps, and various networks, we listed 6 examples of web3 projects that can are likely to stay with us well into the future.
- Arbitrum – an optimistic roll-up solution for web3
As of 2022, over 500,000 tokens were created on the Ethereum blockchain. Even though a significant portion of them are stored only and only used infrequently in transactions, they still create a lot of activity on the chain. The chain is also constrained (for now) by the slower and less energy-efficient Proof of Work consensus.
All these factors combined with an increasing number of people using cryptocurrencies has led to the heavy congestion of the Ethereum network. And, as more and more transactions need to be confirmed, the price of each transaction (or “gas fee”), increases.
That is why developers are looking for Ethereum scaling solutions to make the network cheaper and more efficient. One of the most promising examples of those are optimistic rollups – smart contracts that execute transactions off-chain and post only the results of computations. Thanks to that, calculations are done in a faster and cheaper way.
Arbitrum is a leading web3 project in the optimistic rollup space. It gives web3 developers tools to build apps and solutions that are not only faster and cheaper in use but also compatible with other Ethereum-based tools. Moreover, end-users also can benefit directly from Aribtrum’s optimistic rollup. They can easily bridge their assets from Ethereum to the Arbitrum network and carry out significantly cheaper transactions, for example, while buying NFTs.
- Polygon – a layer-2 web3 project
Rollups are not the only blockchain projects to address Ethereum’s chain congestion and high fees. One of the first layer-2 scaling solutions that attracted the attention of web3 enthusiasts and developers was Polygon.
Polygon positions itself as the “Ethereum’s Internet of Blockchains.” Its goal is to help the congested Ethereum network scale by providing developers tools to build their own layer-2 scaling solutions. Thanks to Polygon, developers can build the rollups and other features (such as sidechains) and connect their ventures with other projects running on Ethereum.
Like Arbitrum, Polygon is another example of a web3 project that provides value for both developers and their end users. While coders can easily design dApps with built-in scaling solutions, users benefit from the Polygon bridge which enables them to enjoy quicker and significantly faster transactions on the Ethereum network, while paying lower gas fees – leaving more funds on their web3 wallets.
- Axie Infinity – the king of play-to-earn projects
In web3, users can not only save their funds and earn money because of successful investments. Projects belonging to the so-called play-to-earn category of apps allow them to acquire cryptocurrencies while playing games.
Axie Infinity caught the attention of many investors in 2021. The game became so popular that its users developed entire communities and guilds to exchange best practices and revenue-sharing opportunities.
The unique idea behind Axie Infinity enabled players to create their own in-game economics and earn real money while trading NFTs and fungible tokens, which they acquired while playing the game. As the price of game-related tokens spiked significantly, users could treat them as a source of passive income too.
Axie Infinity is a perfect example of a web3 project that can create a fundamental change in the world. The growing adoption of crypto and rapid development of play to earn games will result in more people participating in them over the coming months and years.
- Polkadot – interoperability for web3
The blockchain space remains fragmented and incoherent. Protocols and tools still compete with each other to become “the main force” of the internet of the future.
While competition remains beneficial for web3 development, it hinders blockchain accessibility for ordinary users and even coders. They just don’t know which network to choose – both for creating dApps as well as daily activities related to crypto investments, for example. In simple terms, blockchain users shouldn't need to know what chain they’re using while making token transactions or minting NFTs. Their accustomed to low friction and highly polished user experiences that successful ecommerce firms have delivered on web3. And they want the same on web3.
That’s where interoperability solutions come into play. The aim of web3 projects like Polkadot is to connect different chains and enable simple and seamless communication between them. Thanks to project like Polkadot, users stand to benefit from faster, cheaper, and – most importantly – more accessible products and services.
Polkadot doesn’t want to compete with well-known networks like Ethereum. On the contrary, the project’s goal is to connect Ethereum-based tools and solutions with other chains so that they can be perfectly interoperable. Then, users deterred by more complicated solutions (e.g., bridges) will be able to use UX-friendly and understandable tools instead.
- Harmony – a sharding solution for web3
What happens when we combine Polkadot's interoperability with Ethereum's scalability? Harmony.
Harmony is an example of a web3 project designed to solve the blockchain trilemma. As blockchains always have to balance between scalability, security, and decentralization, the innovation behind Harmony makes it reachable to achieve all these three goals. It’s possible thanks to the first successful implementation of a sharded Proof-of-Stake blockchain.
As sharding remains one of the most promising layer2 scaling solutions for congested Ethereum blockchain, its usage in the real-world web3 project draws the attention of many blockchain enthusiasts. Moreover, Harmony was able not only able to implement sharding (and achieve scalability of the chain) but also to make its network interoperable with Ethereum-based solutions and decentralized at the same time. Well, that’s solving the blockchain trilemma at its finest!
The Sandbox – NFTs matter in web3
In 2021, NFTs surpassed “crypto” and “Ethereum” in Google searches. Non-Fungible Tokens were on everyone’s lips, bringing great returns as well as big FOMO (fear of missing out) for investors and web3 enthusiasts.
However, we can’t forget that the purpose of NFT is related not only to investments. This kind of token has its utility – attached very much to the case of ownership in the digital world. In other words, thanks to NFTs, people can own and prove their ownership of the digital assets and trade them with other users in the virtual space.
The Sandbox is a perfect example of a web3 project created on top of the utility of NFTs. It’s a vast ecosystem focused on combining monetization with superior gaming experiences. Thanks to combining NFTs with the marketplace (Sandbox Marketplace) and tools for non-fungible token creation (VoxEdit), players and designers can earn money for their virtual activities. They can even build their own play-to-earn games – using the Game Maker solution.
