Blockchain of Blockchains: Polkadot Overview.

Polkadot crypto software was designed to incentivize computer networks globally for efficient operations of a blockchain network. On this blockchain network, users can operate and launch their blockchains. This unique feature makes Polkadot one of the leading blockchains in the crypto industry. So, in a nutshell, the Polkadot network is creating a blockchain that can host an ecosystem of blockchains.

It’s intriguing to see a newly developed blockchain like Polkadot compete against older established blockchains like Bitcoin and Ethereum. Polkadot is now establishing itself as a next-generation blockchain network, which is interesting to see indeed. We will show you what is Polkadot, how to buy Polkadot coin, and which DOT coin wallet you can use to store your Polkadot crypto.

What is Polkadot?

Polkadot is dubbed as the ‘Blockchain of blockchains’’ or what you would call a “multi-chain”. To fully comprehend the DOT crypto, it’s necessary to understand its framework. Gavin Wood, “the former CTO of Ethereum” is known to head the team behind the Polkadot project.

Gavin Wood believes the Polkadot project will make the perfect alternative and solution to Ethereum’s 2.0 currently undergoing development. The main aim of Polkadot now is to become a fully scalable, heterogeneous network that functions to create multi-chain technology.

Web3 Foundation described Polkadot as the next-gen blockchain. The Web3 (a Swiss organization) Foundation is also behind the project.

Key features

Here are some of the key features of the Polkadot ecosystem.

DOT coin

As of December 20, 2021, Polkadot crypto (DOT) is ranked the 11th leading cryptocurrency according to CoinMarketCap. DOT token also serves the purpose of a utility token, providing users with governance, bonding, and staking functions in the network.

With the DOT crypto utility token, holders are granted authority over the Polkadot network. Holders get to decide the network fees, auction dynamics, and new parachains addition schedule.

Holders can also decide the time appropriate for executing upgrades and making fixes to the platform. DOT coin also ensures the security of the network.

Running as a Proof-of-Stake protocol requires Polkadot coin holders to validate transactions that run across the parachains. However, holders will have to stake their DOT tokens to participate in the protocol.

DOT is also utilized to add new Polkadot parachains simply by holding DOT coins. The process is also referred to as “Bonding”. Once the process is started, the DOT coins become unavailable for usage until their bonding period is over and the parachain is detached.

Polkadot Network

Polkadot multi-chain revolves around its two main structural components, which are the Relay chain and the Polkadot Parachains. Relay chain serves as the central framework responsible for security, consensus, and cross-chain interoperability across the network. The Relay chain functionality has also been intentionally reduced, as a result, eliminating smart contracts functionality on it.

Just like most PoS blockchains, Relay chain requires validators to stake DOT thus achieving consensus. Its validation mechanism is described as the “Nominated Proof-of-Stake”.

Nominators will have to bind themselves to a Polkadot validator before being approved to mine the blocks. To guarantee trust between validators and nominators, profits and losses are shared between nominators and validators.

Polkadot technology

  • Polkadot Validators

Validators handle data validation in parachain blocks. Validators are allowed to participate in consensus and vote on proposed changes to the network. Lastly, validators ensure the security of the network while supporting the production of new blocks.

  • Polkadot Parachain

Polkadot platform hosts зarachains as independent blockchains. The purpose of these custom-built blockchains is to accomplish specific functions, as well as overcome certain obstacles in the crypto industry. Polkadot parachains also utilize Polkadot’s computing resources for accurate validation of transactions on the network.

They’re also free to develop their governance systems by utilizing the Polkadot shared security function. Running a parachain on the Polkadot requires the supposed project to lease a slot on the relay chain via slot auction.


Polkadot platform aims to provide the most innovative, secured and scalable network. With the launch of the Genesis block of its relay chain in May 2020, Polkadot roadmap continued to focus on launching several parachains in 2021.

  • Current Phase of Polkadot roadmap

Parachain Rollout: According to the whitepaper, Parachains are the final piece of the Polkadot functionality to be provided. It allows Polkadot to complete its scalable multi-chain architecture. Parachains will be finally launched on the Polkadot after completing a series of tests, optimizations, and auditing. After that, they will be enabled via on-chain governance.

After the launch of Parachains, additional features and network upgrades will be up to the community to decide as time goes on.

  • Future Upgrades on the Polkadot roadmap

Part of Polkadot future upgrades includes XCMP upgrades (Cross-chain Message Passing) and Parathreads launch. Polkadot’s on-chain governance community will enable these upgrades after the development, testing, benchmarking, and auditing have been completed.
