Detailed guide to Polkadot dApp development

Blockchain technology is transforming everything coming along its way. The popularity of the technology is increasing the number of blockchain protocols too. Today, countless protocols are emerging each day that serve different purposes and address previous generations’ limitations. However, the siloed architecture of previous protocols limited the communication between different blockchain protocols and also cross-chain exchanges. 

Polkadot development has unlocked new potential for the technology. Polkadot’s primary concern is to solve the issues of the previous generation protocols. The protocol emerged as a superhighway connecting different blockchains together and allowed the hosting of dApps. 

This article will guide you through the protocol and the process of building dApps on Polkadot. 

What is Polkadot dApps? 

Polkadot is a promising blockchain protocol that interconnects various types of blockchain protocols with different consensus algorithms and allows them to work together smoothly. The blockchain protocol can facilitate data exchange, cross-chain composability, transparent governance, upgradeability, and heterogeneous sharding. 

The features of Polkadot make it well-suited for tackling the challenges of the modern world and developing custom-built decentralized applications. Polkadot dApp development is rising exponentially. This is because they allow dApps to communicate and exchange data with other dApps on different blockchain platforms. Besides interoperability and cross-chain communication, Polakdot dApps offer scalability, high-level security, and transparency.


Why build dApps on Polkadot?

The demand for Polkadot dApps continues to grow, encouraging businesses to build and host their own robust dApps. Polkadot blockchain development services offer a wide range of benefits for dApps development. 

Sharding: Polkadot’s heterogeneous sharding model allows each chain to be optimized for specific uses rather than adhering to a one-size-fits-all model, paving the way for endless innovations. 

Scalability: Polkadot allows multiple transactions to be processed at the same time. In the sharded system of Polkadot, specialized chains come together and overcome bottlenecks associated with older networks.

Transparent governance system: All the holders of the protocol’s native currency, DOT, are allowed to participate in the governance system of the platform by voting and proposing new amendments to the protocol. 

Steps required for Polkadot dApp development 

Decentralized applications (dApps) can be built on Polkadot using the Substrate framework. 

Step 1

Substrate simplifies the process of setting up a blockchain application for Polkadot developers. This is because it offers a pre-configured node template that allows focusing on developing custom features for the project. These templates are already formatted and ready to use. Using a substrate template, the process of developing dApp on Polakdot becomes streamlined. 

Further, to integrate the Nightly build using Rust, use the command: rustup update nightly rustup target add wasm32-unknown-unknown — toolchain nightly

After that, change the directory and look for the latest version of the repository. The repositories will help save the Rust files that can be customized later on as per the project’s need. After this, compile the node template using the command and get the template running within the project. 

Later, set up a frontend app to interact with the decentralized application running on the network terminal and install the yarn. 

Step 2 

In order to complete the development process, the new Polkadot dApp must be tested and deployed using Rococo. Rococo is a testnet for Polkadot parachains that uses a consensus mechanism called proof-of-authority. Once the dApp has been tested on the testnet, it is ready for deployment.



Even though blockchain platforms may have unique features, they cannot be of much use if they cannot communicate with other blockchains. Interoperability, therefore, has become an increasingly important feature of blockchains globally. 

Polkadot addresses interoperability and scalability issues through multi-chain compatibility and architecture. Developing dApps on Polkadot is a reliable and stable process. With all the features and capabilities, Polkadot is recognized as one of the most innovative developments in the blockchain industry. The next few months will be crucial in determining the full potential of Polkadot dApps and the network.
