Introduction to Polkadot Based Parachain Development

  • by


Polkadot is a protocol that allows data to transfer across different blockchain systems offering an ecosystem to initiate DeFi infrastructure for heterogeneous sharding, transparency and adaptability. Polkadot is basically a sharded multichain network that processes multiple transactions on several chains in parallel, eliminating bottlenecks that occurred on traditional networks that processed transactions one by one. Since Polkadot uses parallel processing power, it improves the scalability and creates the right conditions for increased adoption and future growth. The sharded chains connected to Polkadot are called Parachains because they run on the network in parallel.


A parachain is an application-specific data structure that is globally coherent and validatable by the validators of the Relay Chain. Parachains take the form of blockchain but they are not an actual blockchain. The term parachain is derived from the concept of parallelized chains that run parallel to the Relay Chain. Since they function in a parallel manner, they are able to parallelize the transaction processing and achieve scalability of the Polkadot system. They share the security of the entire network and can communicate with other parachains through XCMP.

Parachains are maintained by a network maintainer called a collator. The role of the collator node is to maintain a full node of the parachain, retain all necessary information of the parachain, and produce new block candidates to pass to the Relay
Chain validators for verification and inclusion in the shared state of Polkadot.

The incentivization of a collator node is an implementation of the detail of the parachain. They are not required to be staked on the Relay Chain or own DOT tokens unless stipulated to do so by the parachain implementation.




Parachains can be specialized into several blockchains providing a variety of services such as identity management, service for finance, etc.


Flexibility means that each parachain can have its own design, token and governance process, optimized for its specific use cases.


With the parachain model, Polkadot allows blockchains to achieve scalability at layer 1 rather than relying on layer 2 solutions. This is a more decentralized and efficient means of achieving blockchain scalability. Parachains allow transactions to be spread out and processed in parallel over an ecosystem of specialized layer 1 blockchains, significantly improving throughput and scalability.


Parachains allow blockchain communities to have full control and sovereignty over their own layer 1 blockchain while also benefiting from the possibility to engage in free trade with other parachains and external networks. Polkadot’s cross-chain composability allows not only the exchange of tokens, but also any type of data, including smart contracts, verifiable credentials, and off-chain information from oracles such as stock market price feeds.


Parachains on Polkadot are free to adopt whatever governance model they see fit, and can access a number of pre-built modules for implementing various on-chain governance systems. The ability to access sophisticated on-chain governance mechanisms allow teams to significantly reduce the likelihood of hard forks of their chain that could risk splitting their communities in two. On-chain governance also provides a means of accountable transparency for parachain communities, a prerequisite for many institutions and fiduciaries that often need to see clear decision-making processes before getting involved in blockchain technology.


Every blockchain is based on three principles such as decentralization, scalability and security. The challenge of completely utilizing all these principles is yet to be overcome. Decentralization is easily achieved by almost every blockchain development company, but ensuring scalability and security causes some obstacles to overcome.

The speed of transaction handling and data processing supported data volumes and the security of blockchain data and small contracts should be improved.

In order to initiate the parachain development, the obstacle of cross-blockchain interoperability must be rectified.

Cryptocurrency exchanges and many other blockchain-based services need new ways to interact with other blockchains and exchange data with them. Even the simplest and common exchange of Ethereum to Bitcoin can be done a lot simpler with convenient blockchain interoperability.

While blockchain interoperability is important for effective cooperation, most existing solutions that provide cross-blockchain communication are complicated, overloaded, narrow and include a third party. Often, they are not completely secure.

In order to reduce these risks, The Polkadot Network is initiating a Polkadot based parachain development for blockchain to safely and reliably interact. This type of parachain development allows for the creation of new blockchains, or parachains, connected to the main Polkadot chain. This Polkadot based parachain development creates the possibility to send messages and transactions between chains, providing shared security and great potential for scaling.
