What is Polkadot (DOT)

Polkadot is a decentralized platform that uses blockchain technology to enable the creation of interconnected, independent networks called “parachains.” It was developed by the Web3 Foundation and has gained significant attention in the blockchain industry due to its innovative approach to scalability, interoperability, and governance. In this article, we will explore what Polkadot is, how it works, and its potential impact on the future of decentralized technology.


Gavin Wood, a co-founder and the first CTO of Ethereum, played a key role in the development of the Ethereum network and the creation of the smart contract language Solidity. However, while these were major innovations at the time, it became apparent that Ethereum’s all-purpose design imposed limitations on developers, such as high gas fees and a lack of core upgradeability. Blockchain frameworks that attempt to do everything on a single chain may be hindered by general design choices and make it difficult for developers to create specialized solutions.

To further advance the capabilities of blockchain technology, Gavin left the Ethereum Foundation and started Parity. He led the development of the fastest Ethereum client at the time, as well as clients for Bitcoin and ZCash. This led to the creation of Polkadot, a new way of thinking about blockchains. Through his extensive experience in the industry, Gavin was able to envision new possibilities for blockchains, resulting in the development of Substrate, an open-source, future-proof framework that enables a multichain, interoperable, and decentralized internet with which he built Polkadot.


At its core, Polkadot is a decentralized platform that allows for the creation of multiple blockchain networks, called “parachains,” that can interact and interoperate with each other. These parachains can be used to build a wide range of decentralized applications (dApps) and services, such as decentralized finance (DeFi) platforms, identity systems, and supply chain solutions.

One of the key features of Polkadot is its focus on scalability. It uses a novel approach called “sharding,” which allows it to process transactions in parallel across multiple parachains, improving the overall speed and efficiency of the platform. Additionally, Polkadot uses a system of “collators” who are responsible for validating and organizing transactions, which helps to reduce the burden on the network and improve its scalability.

Another key feature of Polkadot is its focus on interoperability. It allows for the seamless exchange of data and value between different blockchain networks, enabling a wide range of applications and use cases that were previously not possible. This is achieved through the use of “bridges,” which are specialized parachains that connect different blockchain networks and enable their interaction.

In terms of governance, Polkadot utilizes a decentralized decision-making process called “referendum,” which allows its community to vote on important decisions related to the direction and development of the platform. It also has a system of “validators,” who are responsible for verifying and organizing transactions on the network, and are incentivized to act honestly and accurately through a system of rewards and penalties.

So far, Polkadot has gained significant traction in the blockchain industry and has attracted a number of high-profile projects and partnerships. It has also received significant funding from venture capital firms and has a strong development team with a clear vision for the future.

Overall, Polkadot is a promising platform that has the potential to have a significant impact on the future of decentralized technology. Its focus on scalability, interoperability, and governance sets it apart from other platforms and positions it well to play a leading role in the development of the decentralized web.
