Polkadot, like many cryptocurrencies developed after Bitcoin, functions as a tradable token on trusted crypto exchanges and as a decentralized protocol. The goal of this blog is to help you understand this next-generation blockchain protocol and how it works.

What is Polkadot?

Polkadot is a next-generation blockchain protocol designed to integrate multiple blockchains into a single network. Launched to decentralize the web, it gives control to individual users rather than internet monopolies. Essentially, the goal of the protocol is to create a global network of computers that run a primary blockchain on which individuals can run their own blockchains.

Dr. Gavin Wood, one of the founders of Ethereum and author of the Solidity smart contract programming language, is an important figure behind Polkadot. Co-founder Robert Habermeier is a prominent member of the Rust programming language community. it builds on the concepts of earlier blockchain networks like Ethereum and Cardano.

Why create a new blockchain protocol when platforms like Ethereum already exist? Polkadot’s creators believe that no single blockchain can serve all purposes efficiently and at scale. Dot connects different blockchains, each offering different services. So Polkadot can theoretically support any project or service you can imagine.

How does Polkadot work?

The key components of Polkadot are the Relay Chain, Parachains and Bridges.

  1. Relay chain: Relay Chain is Polkadot’s primary blockchain where transactions are verified. To increase speed, Polkadot separates the process of adding new transactions from the verification process. Relay Chain uses a variant of Proof-of-Stake (PoS) consensus called Nominated Proof-of-Stake (NPoS). This allows DOT (native Polkadot token) staking users to act as:

Validators: Validate transactions, participate in consensus, and vote on network proposals.

Nominators: Secure the Relay Chain by selecting trusted validators and assigning their staked DOT tokens to them.

Collators: Maintain transaction history on parachains and send data to the Relay Chain for verification.

Fishermen: Monitor the network and report suspicious activities to validators.

  1. Parachains: Parachains are independent blockchains running on Relay Chain, each serving a specific purpose and using Relay Chain resources to verify transactions. Parachains have their own spawners responsible for producing blocks. Polkadot plans to have a limited number of parachains with potential for expansion.
  1. Bridges: Bridges are special parachains that connect other blockchains to those in the Polkadot ecosystem. They enable seamless token transfers between Polkadot and other networks such as EOS, Cosmos, Ethereum and Bitcoin without the need for a centralized exchange.

Advantages of Polkadot over other blockchains

Scalability and speed: Unlike first- and second-generation blockchains that struggle with transaction speed, Polkadot’s parallel processing through parachains and validators greatly increases network speed.

Specialization: Polkadot does not need to develop a single chain for all services. Different parachains may specialize in different services, such as file storage, decentralized identity management, or stablecoin payments.

Interoperability: Polkadot parachains can communicate and cooperate with each other, enabling the transfer of tokens and the exchange of information, like a financial services parachain interacting with an oracle chain providing real-world data.

Governance: The Polkadot community manages the network in a decentralized manner. As governance shifts to users, community suggestions will improve the network, making it flexible and user-driven.

Easy upgrades: Polkadot allows upgrades without hard forks, which prevents the network from splitting like Bitcoin Cash. The network is designed to improve gradually through frequent updates.

Polkadot Faces Challenges

The complexity of architecture: Polkadot’s complex architecture can be intimidating for newcomers as it requires advanced technical knowledge to understand and implement compared to simpler blockchain platforms.

Scalability and interoperability testing: As a newer blockchain, the scalability and interoperability of Polkadot have not been fully tested at scale, raising questions about its long-term performance, security, and ability to handle growing numbers of users and transactions.

Is a dot a good investment?

Polkadot has the potential to revolutionize blockchain with its interoperability and scalability, competing with giants like Bitcoin and Ethereum. The network is expected to attract innovative projects and new use cases for decentralized networks and cryptocurrencies. The DOT token has a strong market position and reinforces Polkadot’s reputation. So an investment in Polkadot could be promising.
