dApps is still a nascent technology, but it is gaining momentum. The market size of decentralized apps is projected to reach USD 21,070.2 million by the end of 2025. Data privacy, lack of censorship, and developers’ flexibility are among the benefits that decentralization brings.

While dApps are built and run on blockchain networks, RPC technology is becoming a crucial building block for decentralized projects.

What is RPC?

The acronym RPC in the crypto sphere stands for Remote Procedure Call. RPCs are essential because they enable developers to connect one Web3 network (such as Bitcoin, Ethereum, or Polygon blockchains) with another. One of the critical use cases for RPC is developing dApps that have the capability to interact with more than one blockchain.

RPC is a vital link between the user of dApp, the application, and the on-chain information between blockchain nodes. Decentralized applications are powered by smart contracts that enable the execution of tasks, such as transactions, populating wallet balances, or fetching ownership information.

dApps provide a user interface to end-users. The RPC layer built into dApps allows separate parties to communicate with each other. For example, when using MetaMask to conduct transactions, users’ requests are routed through an RPC to reach the data on the blockchain.

Makes Building dApps Easier

Having an RPC layer is a crucial first step in building the blockchain’s ecosystem. Mainly because RPC simplifies the building process of dApps. Also, it allows querying blockchain data without access to your own node.

To build decentralized applications, developers need to access a massive load of on-chain information like node connections, historical blockchain data, transactions, and block numbers. All this is done by making “requests” to the blockchain and receiving replies with needed data.

To do that, developers can set up a node themselves. However, it comes with handling DevOps tasks like server troubleshooting and equipment maintenance. Often a more effortless and faster solution to gain access to blockchains is using services from Web3 infrastructure providers via an RPC layer.

Several players in the industry provide RPC services, one of which is Ankr. The provider recently made headlines by being the preferred choice as an RPC provider for the new Aptos blockchain. The blockchain, founded by Meta’s former employees, secured $200 million in funding back in March this year and launched its mainnet this week.

While Aptos made their network live, the ecosystem is in the development phase, where many puzzle pieces are still missing. However, by adding the RPC layer, the blockchain creators opened the network for dApps developers to start building on top of it quickly.

On the Flipside

From the development side, working with RPC nodes also has weaknesses and drawbacks. RPC nodes require a lot of requests, which demands a lot of work and back-and-forth communication, which makes the code inefficient. In contrast to some of the most sophisticated Web3 development tools out now, building blockchain infrastructure around RPC nodes could be limiting.

Why You Should Care

dApps are a crucial part of the Web3 revolution that empowers the user to own their data. The further development of this technology will bring new opportunities and could even change how the internet is perceived.
