What Is A Polkadot Parachain?

by

Polkadot stands out among projects dedicated to enhancing the fundamental technology behind decentralized apps (dApps), achieving great success.

Polkadot includes parachains, which are self-governing blockchains that seamlessly connect to Polkadot. Parachains function independently but can communicate with Polkadot and other linked parachains, fostering interoperability within the Polkadot network.

What Is A Polkdadot Parachain?

Gavin Wood and Peter Czaban established Polkadot in 2016. Wood penned the project’s whitepaper that same year, and later founded the Web3 foundation in 2017. This organization secured $188 million through token sales – including an initial round and a private sale in 2019. Polkadot aims to tackle three major obstacles limiting the expansion and acceptance of blockchain technology: slow transaction speeds, limited scalability, and weak security.

Polkadot is designed for improved scalability by featuring specialized blockchains called parachains. These parachains enable secure and trustless interaction and operation within the network. Both Polkadot and its related platform Kusama have a relay chain at their core, which oversees a network of parachains. The Relay Chain handles specific transaction types such as governance functions, parachain bidding processes, and consensus. All other actions are carried out by the linked parachains.

Parachains function as specialized data processing units linked to the Polkadot relay chain. They process transactions and have their own distinct structures, validation mechanisms, and economies, including native tokens. The conditions for implementing a parachain can vary, such as requiring collator nodes to pledge DOT tokens to the relay chain. Collator nodes are motivated by rewards in the form of the parachain’s native token or alternative incentives.

The ability of Polkadot’s parachains to interact with one another through cross-chain compatibility and interoperability has generated much excitement. This feature lets parachains exchange any kind of data or assets with other parachains, expanding their capabilities to serve multiple use cases and applications. Additionally, they can leverage the security, scalability, and governance features of the larger Polkadot network.

Benefits Of Parachains 

Parachains offer several benefits. Let’s discuss some of them briefly. 

Interoperability 

One major benefit of parachains in Polkadot is their capacity to connect with other chains and networks, enhancing the overall compatibility of the Polkadot system. As independent blockchains, parachains offer full autonomy to community groups, enabling interaction with other parachains and external networks. Moreover, they can utilize Polkadot’s interoperability features for seamless token and data exchange, including smart contract interactions, credentials sharing, and access to off-chain information from oracles.

Scalability 

Normally, blockchains require the use of Layer-2 methods for achieving interoperability. But uniquely, parachains enable interoperability at Layer-1. This results in a more efficient approach to scaling and increasing throughput. Transactions can be distributed and processed concurrently across a network of Layer-1 blockchains.

Flexibility 

Polkadot allows maximum flexibility when creating Parachains, enabling each one to have unique features. As a result, Parachains can function as standalone networks with distinct governance structures and native tokens. They can operate publicly or privately, and developers can build applications on top of them.

Governance 

Parachains have the flexibility to choose any governance structure they prefer and can incorporate pre-existing modules to establish various on-chain governance frameworks. By offering multiple governance options, we minimize the risk of network splits among Parachains. Additionally, having on-chain governance enables Parachains and their user bases to maintain a clear and open decision-making process.

What Are Some Use Cases Of Parachains? 

Parachains can be used in several areas, businesses, and industries. Some examples are: 

  • Decentralized Finance 

  • Identity verification

  • Internet of Things 

  • Gaming

  • Smart contracts

  • Digital wallets

  • Oracles
