What is Polkadot (DOT)? Everything you need to know about DOT token

publish_by Razel at 25 tháng 11 2021

Gavin Wood, co-founder of Ethereum, noticed that no blockchain is perfect, and development will put more and more operational pressure on each blockchain. So let's make it easier for people to build the blockchain they want, and at the same time create a network to connect those chains to upgrade scalability. Therefore, he created Polkadot to become a network for many different layer 1 platforms like Ethereum to run on.

In this article, I will introduce you to Polkadot, including the following information:

  • What are Polkadot and the DOT token? How does Polkadot work?
  • Specific details about DOT token and its tokenomics, including its up-to-date price, key metrics, distribution and use cases.
  • How to get DOT? Where to store it?
  • Roadmap & information about team, investors and partners.

What is Polkadot?

Polkadot allows blockchains to connect with each other to share data and form a decentralized network. If chains like Ethereum, Solana, Polygon are layer 1 platforms, then Polkadot can be understood as a layer 0 platform that connects layer 1 platforms.

Polkadot's vision is to create a "Decentralized Web - Decentralized Network". Polkadot focuses on solving two main problems of Blockchain: Interoperability and Scalability.

How does Polkadot work?

Network structure

Relaychain: Is Polkadot's Central Chain, responsible for connecting Validates to Parachains. Specifically, the Validators will Stake DOT on Relaychain to protect the network transactions including network administration. Transaction fees on Relay Chain will be higher than those on Parachain.

Parachain: Parachain can be understood as the position of layer 1 platforms when connected to Polkadot's Relay chain. Basically, Parachain is not necessarily a Blockchain. It can be a Dapp or a Data Structure, as long as it can provide proof that can be verified by the Validators assigned to that Parachain. Most of the computation that happens on the entire Polkadot network will happen on Parachain.

Parathread: Similar to Parachain but with a pay-as-you-go model ⇒ More savings for blockchains that don't need a constant connection to the network.

Bridges Chain: It can be envisioned as a bridge between Polkadot Network and other Blockchains, providing interoperability between networks.

The whole network

Substrate: Substrate can simply be understood as a framework that makes it easier to build Blockchain. Projects built with Substrate can run on Polkadot, but projects built on Substrate can exist as a standalone platform.

Components of the Polkadot network

Polkadot Consensus Role

Polkadot's network consists of 4 main components:

  • Validators: Producing Relay Chain blocks, responsible for validating and adding new blocks to the Relay Chain. Validators will stake DOT to protect the Relay Chain network
  • Collators: Monitor transactions occurring on Parachain and send proof to Validators to maintain network security.
  • Nominators: Nominating Validators, is like delegating your shares to other Validators. When these Validators receive rewards from validating, adding new blocks, some of the rewards will be shared back to Nominators. This is similar to Delegate on DPoS.
  • Fisherman: Monitor the network and report bad behaviors to Validators. Collators and any parachain full node can perform the Fisherman role.

What makes Polkadot special?

Polkadot was born to solve the following problems:

  • Heterogeneous Sharding: Different blockchains can run in the same network.
  • Scalability: The sharding model allows parallel procession of many transactions, eliminating the problems that existed on individual chains such as Ethereum due to sequential transaction processing.
  • Upgradeability: Blockchain upgrades sometimes require forking the network, which involves a lot of time and effort. Also, in the case of hard forks, a unanimous community decision is another issue.The Polkadot network supports blockchains to upgrade themselves without the need to chain fork.
  • Cross-Chain Composability: Polkadot supports cross-chain communication. Segments can deliver messages to communicate, exchange value, and share functionality. This is the biggest barrier for crypto users, because the separation between chains creates a disruption in the adoption of crypto products.

Polkadot is built as a network layer 0, allowing Layer 1 platforms like Ethereum to work together on the same network. As the crypto market expands with many new chains appearing, Polkadot is built with the purpose of becoming the next step of the crypto market, connecting single pieces into a unified whole.

DOT Token Use Cases

DOT is Polkadot’s native token which has the following use cases:

  • Staking to do Validator.
  • Parachain Auction: When a project wants a slot for Parachain, they will have to go for an auction. When the auction is successful, this DOT number will be locked.
  • DOT is the governance token of Polkadot.

Current phase: Parachain roll out

Currently, the parachain slot on Kusama (Polkadot's test network) has been put into operation and has had 10 successful auctions. According to the announcement, by the end of November, the parachain in Polkadot will be officially ready for projects to take part in the Polkadot Relaychain network. This is the stage when the network is officially used and projects on Polkadot can be realized.

Team, Investors and Partners


  • Gavin Wood, co-founder of Ethereum, the founder of the Solidity programming language, wrote the Yellow Paper for the Ethereum Virtual Machine, and served as the first Chief Technology Officer (CTO) of the Ethereum Foundation.
  • After leaving Ethereum in 2016, Wood co-founded Parity Technologies (formerly Ethcore), a company that develops core infrastructure for Ethereum, Bitcoin, Zcash, and Polkadot; and then the Web3 Foundation, a nonprofit organization focusing on decentralized internet technology and infrastructure, starting with the Polkadot network. In short, Gavin Wood is the one who built up the foundation of the crypto market.

With that being said, WEB3 Foundation and Parity Technology were the first to support the development of the crypto world. Polkadot was supported in the aspects of finance, technology and system administration from WEB3 and Parity Technology, show the massive strength of Polkadot compare to other project on the market.


Polkadot has many investors who are hedge funds and venture capital, some of which are Three Arrows Capital, CoinFund, Kenetic Capital, Genesis Block, NGC. With the number of more than 50 investors, Polkadot is a project of great stature and strong guarantee.


Polkadot has an ecosystem, so the project has many partners; all projects participating in parachain or auctioning parachain slots are partners of Polkadot.

Similar Projects

Polkadot's direct competitor in building a network of layer 1 platforms is Cosmos. Up to the time of this article, it can be seen that Cosmos has had clearer activities than Polkadot when there have been many successful projects operating and developing on the Cosmos network such as Binance chain (BNB), Thorchain (RUNE) or Terra ( LUNA).


In comparison, Polkadot and Cosmos are in different stages; while the Cosmos network has been active for a while, Polkadot is still waiting for the parachain implementation. This network will need time, until the Polkadot ecosystem goes into operation, then we will have a clearer view of the differences between these two layer 0 networks.

Is Polkadot (DOT) a good investment?

I hope that you have understood what Polkadot is with the information mentioned above. This article should give you a deep insight into the project, so there is no financial advice. You should Do Your Own Research before conducting any investment and be responsible for your own fund.

However, Coin98 will provide some notable points about the project to give you the best overview to make your own decisions.

In the crypto market, there are more and more layer 1 platforms such as Solana, Polygon, Celo. The independent operation of current chains is having problems in usage barriers, scalability and asset portability. Polkadot was created to solve those problems, as layer 1 platforms built on parachain can focus more deeply on specific purposes such as gaming, DeFi or transactions, which is a significant change compared to the current blockchains that are all responsible for becoming one for all platforms.

Currently, the network on Polkadot is waiting for the parachain to be ready so that projects can start working on Polkadot, so the expectation about the potential of the project on Polkadot network is worth looking forward to.

Gavin Wood is the co-founder of Ethereum, we can understand him as one of the founders of the current crypto world, and Polkadot was built by Gavin to be the next evolution of the crypto market in the future. The fact that the project was born with a backer like Gavin Wood with the WEB3 foundation can be worth our trust.


Polkadot is built with the purpose to be the “Internet of blockchain”, allowing individual chains to operate on the same network, helping to solve the current problems of scalability, interoperability between different chains to make the application of crypto easier.

Because there is no perfect blockchain that can support all activities in the crypto world, Polkadot will help the development of chains become more specialized, creating an efficient network. Built by the people who know the best about crypto development, Polkadot's ability in the future is worth the trust.
