What is Polkadot?

Polkadot’s primary mission is to help multiple separate seemingly incompatible blockchains all work together like they are compatible. Traditional blockchains operate pretty much all alone, limiting their ability to communicate and share data.

Polkadot changes the game by connecting these blockchains — like a digital highway where information flows freely between different projects.

The DOT token or cryptocurrency is used in the Polkadot ecosystem.

The relay chain and parachains

Polkadot’s architecture revolves around the Relay Chain. Around it orbit various parachains — individual blockchains with specific uses. These parachains can specialise in anything from decentralised finance (DeFi) to gaming or identity management.

Because Polkadot doesn’t have apps on it, it’s called a zero layer, because it is a foundation layer. But the parachains around it do have dApps (apps made on a blockchain rather than the internet). Here are some really cool parachains to look into.

Imagine Polkadot as a bustling city with different districts, each serving a unique purpose. The Relay Chain ensures seamless communication between these districts.

Scalability and efficiency

By spreading transactions across multiple parachains, it achieves faster processing and efficient resource use. Unlike congested highways during rush hour, Polkadot’s lanes remain open and efficient.


Developers can create their own parachains using the Substrate framework. It’s like building with Lego blocks — assemble your unique blockchain, connect it to Polkadot, and benefit from the network’s security and interoperability.

This flexibility encourages innovation and rapid development.

DOT Token

Polkadot (DOT) was launched through its initial coin offering (ICO) in October 2017.

During the ICO, the initial price of Polkadot was US$0.29, and a total of 2.24 million tokens were offered. Since then, Polkadot has evolved significantly, and its price has experienced wild fluctuations. At its all-time high price, it was trading at US$55, in October of 2021, however at the time of writing the price of DOT was US$7.70.

The native DOT token serves several purposes. It can just be a speculative investment. People buy the token at what they think is a low price, and sell when they think it won’t go much higher. (Or they buy it at the top of the market and end up having to sell after the price drops!)

Other uses of DOT

Governance: DOT holders participate in decision-making, shaping Polkadot’s future.

Staking: Lock up DOT to secure the network and earn rewards.

Bonding: Parachains use DOT as collateral to secure a slot on the Relay Chain.

Owning DOT means being an active participant in the Polkadot ecosystem.

Who is Gavin Wood?

Polkadot’s co-founder, Gavin Wood, played a pivotal role in Ethereum’s early days. His vision for Polkadot combines scalability, security, and innovation.

Where is Polkadot headed?

Polkadot’s ecosystem is vibrant and expanding. New projects, collaborations, and use cases emerge regularly. As more parachains join, the network becomes richer and more valuable.

Many people who invest in Polkadot see themselves positioning themselves for tomorrow. Interoperability will be a critical factor as the crypto landscape evolves. However, although Polkadot is a promising project, no one knows for sure what will happen in the future. Don’t invest anything you can’t afford to lose.

Energy Efficiency

Polkadot’s proof-of-stake (NPoS) model consumes significantly less energy than traditional blockchains. It’s environmentally friendly and sustainable.
