What Is Polkadot Blockchain?

2022-08-25 05:25:59

Polkadot is a multichain blockchain designed to enable scalable decentralized computation and interoperability. Polkadot is a blockchain of blockchains that solves the interoperability problem in decentralized systems. Polkadot Network is a multichain network that allows blockchains to connect and share security with other blockchains. This is accomplished by using a single common relay chain to which other blockchains known as parachains are linked, allowing them to take part in the network's consensus protocol. We'll learn about relay chains and parachains in detail in the next subtopic.

A blockchain can be thought of as a node in Polkadot because it connects blockchains and allows blockchains to interact with each other and exchange values with each other, thereby enhancing interoperability. Organizations can leverage Polkadot Multi-chain to build a Blockchain system that runs directly on Polkadot's network and communicate with other blockchains in the network. The Polkadot blockchain's native token is the DOT cryptocurrency, it is used in processing transactions and also used to participate in Polkadot Network governance. Polkadot employs an advanced governance technique that allows it to develop over time at the direction of its decentralized stakeholders. The ultimate purpose is for the majority of the stakeholder to always be able to govern the network. For faster and cheaper functionality, applications on other blockchains and assets can be incorporated into the Polkadot ecosystem. 

Polkadot ecosystem

Polkadot Relay Chains

The Relay Chain is the central component of the Polkadot network. The Relay Chain coordinates and defines how the parachains communicate with one another. The Relay Chain serves several functions. It ensures that the parachains operate in accordance with the protocol set on the Relay Chain, and it also ensures that the parachains communicate in accordance with the Polkadot network's consensus. The parachains that are linked to this chain aid in strengthening the security within the Relay Chain. If the Relay Chain reverts for whatever reason, every parachain on the Polkadot network reverts as well, thereby maintaining consensus and one network protocol.

Polkadot Parachains

Polkadot parachains are autonomous blockchains with their own native tokens that can be utilized for specific use cases. Parachains are a key component of the Polkadot Network. The heterogenous sharded blockchain network was developed and this feature allows each shard or blockchain in the network to have its own unique or customized design. These custom shards are known as parachains. 

A parachain is most typically in the form of a blockchain, but they are not required to be actual blockchains.

Polkadot Bridges

A blockchain bridge is a connection that allows values and/or resources to be transferred between parachains. All blockchains have their own set of protocols, rules, governance, and consensus, Polkadot bridges were developed to bridge these differences and allow secure interoperability between different blockchains.

Polkadot Substrates

A Polkadot Substrate is a blockchain-building framework that enables developers to quickly and effortlessly create future-proof blockchains that are optimized for any use case. Polkadot's system of parallel transactions, cross-chain transfers, and an expanding support network is intended to connect to substrate-based chains seamlessly.

DOT Tokenomics and Data

DOT tokens can be bought and traded on famous centralized and decentralized cryptocurrency exchanges. Credible centralized exchanges like CoinEx, Binance, Coinbase, etc, and decentralized exchanges like Zero Exchange, Polkaswap, Polkadex and Mangata. 

Polkadot Features

1. Network Governance

Polkadot native cryptocurrency DOT is used to govern the network and make decentralized decisions on the direction the network takes. The network participants that make decisions on the network are known as stakeholders. Network upgrades are incorporated on-chain and carried out autonomously. 

2. Security

The Polkadot network allows chains to communicate and exchange resources and value. Whereas the chains maintain their autonomy in governance, they are very cohesive in security.

3. Fork-less Network Upgrades

To integrate new features in the network or fix network issues, the Polkadot network can be upgraded without requiring hard forks. A blockchain fork occurs when network protocols or consensus are changed. Ethereum is undergoing a major fork, with network participants and miners switching from proof-of-work to proof-of-stake consensus. Polkadot can easily adapt to new developments and enhance itself as better technologies emerge due to this fork-less feature.

4. Transactional Scalability

The Polkadot enables transactional scalability by distributing transactions across the multichain. Miners validate transactions across multiple blockchains, ensuring that the multichain is transparent and secure. Miners receive the native token of Polkadot "DOT" as a reward for validating transactions and keeping the multichain secure. 

5. Interoperability

The Polkadot is a multichain network that was built mainly for the purpose of interoperability across blockchains. Building your blockchain on Polkadot allows you to communicate with a wide range of blockchains in the Polkadot network and share values and resources with each other. 

6. Custom blockchains

Custom blockchains can be developed on the Polkadot network using the substrate framework.


In summary, Polkadot is a blockchain that was developed to solve the issue of scaliblity and makes interoperability of blockchains possible. Already developed blockchains can be deployed on Polkadot as parachains and they are linked together, communicate, share values and resources by a consensus following the protocol set by the relaychain. Blockchains are developed in minutes using the feature of polkadot substrate. Polkadot substrate is a blockchain-building framework that enables developers to quickly and effortlessly create blockchains that are optimized for any use case.
