What Are Parachain? Discover How Polkadot’s Game-Changing Tech Is Reshaping Blockchain!

Jakarta, Pintu News – Parachain is a type of independent blockchain that is connected to a larger blockchain network, usually the Polkadot network.

Unlike traditional blockchains like Bitcoin and Ethereum that are isolated and cannot communicate with each other directly, parachains run in parallel with other parachains and can interact seamlessly.

In addition, parachains also utilize Polkadot for shared consensus and network security.

Explanation of Parachain and Kusama Polka Dots

Parachain are blockchains connected to Polkadot or Kusama’s relay chain . They are application-specific data structures that validate transactions with the help of relay chains-thecore structurethat enables secure communication between all connected blockchains (i.e. between parachains).

Parachain is similar to other blockchains such as Ethereum, but is integrated with Polkadot or Kusama’s shared security model. Parachain can be used for various purposes according to the needs of each application.

The name “parachain” comes from the way it runs transactions in parallel. Unlike other scaling solutions such as subnets or shards that are small parts of a large network, parachains are heterogeneous-they stand alone with independent structures and functions.

Polkadot and Kusama are designed for scalability by accommodating specialized blockchains called parachains. These parachains can communicate with each other and operate in a secure,trust-free environment.

Both Polkadot and Kusama have their respective relay chains at the center of their structures, which serve to coordinate the connected parachain system.

Parachains provide a secure and trust-free environment for communication and operational activities, and are optimized for scalability.

Relay chains themselves only handle limited types of transactions such as governance mechanisms, parachain auctions, and network consensus. Other work, such as supporting smart contracts, is carried out by the connected parachains.

Parachain Features and Functions

Parachains are considered layer-one blockchains, so they can run smart contracts-somethingPolkadot cannot do directly.

Various applications such as DEXs (decentralized exchanges), launchpads, DeFi applications, crypto wallets, oracle integrations, APIs, cross-chain bridges, and more can be built as or on top of L1 parachains.

Parachain Features:

• It is a layer 1 blockchain connected to Kusama or Polkadot.
• Unique and tailor-made according to their individual needs, for example for smart contract platforms, DeFi, scaling, gaming, NFTs, and others.
• It can interact natively with other blockchains connected to the same relay chain.
• Supports smart contract hosting.
• Able to produce their own blocks.
• Have their own validators, governance structures, and native tokens.

Connected Blockchain Ecosystem

Polkadot is an interconnected blockchain network that shares a common security system. The ecosystem consists of various parachains that have unique functions, but are connected through a common framework that allows for easy communication.

While stand-alone blockchains often struggle with sharing information or transferring data and tokens between networks, parachains don’t suffer from these issues.

Parachains benefit from rich and efficient interactions thanks to their connection with relay chains and Polkadot’s use of cross-consensus messaging (XCM).

Parachains remain independent-with their own validators, tokens, and governance systems-but can still communicate with each other and exchange data directly.

Due to their ability to focus on specific functions and run in parallel, parachains are often referred to as appchains or application-specific chains.

Parachains are exclusive to the Polkadot and Kusama networks. They are layer one blockchains that are heterogeneous and uniquely designed according to the needs of a particular project-whether it is a permissionless public network, a private chain consortium, or other Web3 technologies.
