December 6th What is Polkadot (DOT)?
education
Polkadot (DOT) has emerged as one of the most innovative projects in the Web3 space, offering a unique approach to scalability, interoperability, and security. Today we’ll take a closer look at the world of Polkadot, its goals, underlying technology, and what’s driving its growing popularity in the cryptocurrency community.
Developed as a multi-chain framework, Polkadot is highly capable of connecting various blockchains into a unified network, allowing them to work together seamlessly. This capability not only solves the long-standing problems of blockchain isolation and data silos, but also paves the way for a more integrated and efficient digital future. As we unpack the layers of Polkadot, we will understand how it is redefining the blockchain landscape and why it is becoming a cornerstone technology in the world of decentralized applications.

Conceptualized by Ethereum co-founder Dr. Gavin Wood, Polkadot was created as an answer to the pressing challenges of scalability and interoperability in blockchain ecosystems. Launched in 2020, it is designed to enable different blockchains to communicate and share information in a secure, trustless environment. This innovative multi-chain framework connects multiple ‘parachains’, or parallel blockchains, each optimized for a specific use case or functionality, to a central relay chain.
The relay chain, the core of Polkadot, is responsible for the network’s shared security, consensus, and interoperability between chains. This allows transactions to be distributed across multiple chains, reducing the burden on a single chain and improving scalability and efficiency. Parachains have a distinct ability to tailor their functionality to specific needs while leveraging the security and interoperability benefits offered by relay chains.
Polkadot also uses an innovative governance model where all token holders have a say in the future of the network. This includes voting on proposed upgrades and changes, which can be implemented without forking the network, ensuring a dynamic and evolving ecosystem.
Additionally, the network uses a directed proof-of-stake (NPoS) consensus mechanism, which is energy efficient and allows for higher scalability than proof-of-work systems. In this system, token holders can stake DOT (Polkadot’s native token) to secure the network, participate in governance, and earn rewards.
How Polkadot Works
Polkadot is designed to solve some of the most pressing challenges facing Web3 chains: interoperability, scalability, and upgradability. Unique architecture and design principles set it apart in the Web3 environment.
At the core of Polkadot’s architecture is a relay chain, which is responsible for network security, consensus, and interoperability between chains. Rather than processing ordinary transactions, it coordinates the entire system, including various parachains.
Polkadot’s parachains are independent blockchains that run in parallel within the Polkadot network. Each parachain can have its own tokens, governance rules, and can be tailored to specific use cases (e.g. smart contracts, file storage, identity management, etc.). They utilize the computing resources of the relay chain to verify the accuracy of the transactions they process.
Polkadot also utilizes parathreads, which are functionally similar to parachains but have a more flexible connectivity model. Parathreads are ideal for blockchains that do not require a persistent connection to the network.
Polkadot also uses cross-chain bridges. This is a special type of parachain or parathread that connects Polkadot to external networks such as Ethereum and Bitcoin, enabling interoperability between Polkadot and other blockchains.
Polkadot uses a variant of proof-of-stake called nominated proof-of-stake (NPoS). In this system, validators secure the network by staking DOT, Polkadot’s native token, and nominators support validators with their own DOT stakes. The system is designed to be more energy efficient and safer.
Polkadot also has an on-chain governance system that allows all stakeholders to have a voice. Changes to the network are proposed and voted on by DOT holders, allowing Polkadot to adapt and upgrade without a hard fork.
Why Polkadot is unique
Polkadot is not just a Web3 chain, but a blockchain of blockchains (often referred to as a multichain network). It aims to create a fully interoperable and scalable web of blockchains, allowing a variety of applications to communicate and operate efficiently. If this vision is fully realized, the capabilities and scope of Web3 could be greatly expanded.
Polkadot is designed to allow different blockchains to transfer messages and value in a trustless manner, connecting different networks. This level of interoperability goes beyond simple token transfers and enables the sharing of a wide range of data and asset types across private, public, permissionless, and permissioned blockchains.
Polkadot’s new shared security model (also known as pooled security) allows multiple chains (parachains) to leverage the collective security of the Polkadot network. This means that even small blockchains can benefit from strong security without having to build their own network of miners or validators.
The network’s ability to process multiple transactions simultaneously on different parachains enables higher scalability. This parallel processing capability is an important step towards solving the scalability issues faced by older blockchains such as Bitcoin and Ethereum.
What is the Polkadot Ecosystem?
- Polkadot relay chain: Relay Chain, the core of the Polkadot network, is responsible for the network’s security, consensus, and cross-chain interoperability. Connects various parachains and facilitates communication between them.
- parachain: It is an independent blockchain connected to Relay Chain. Each parachain can be customized for a specific use case, such as decentralized finance (DeFi), gaming, identity management, or data storage. You can benefit from the shared security and interoperability that relay chains provide.
- parathread: Similar to parachains, but with a pay-as-you-go model, Parathreads are more cost-effective for blockchains that do not require a persistent connection to the Polkadot network.
- bridge: These special parachains, or parathreads, allow Polkadot to connect and communicate with external blockchains such as Ethereum and Bitcoin, enabling interoperability and transfer of data and value across different blockchain networks.
- substrate framework: Substrate, developed by Parity Technologies, is a blockchain building framework used to create custom parachains and parathreads. It offers flexibility and ease of development, significantly lowering the barriers to blockchain creation.
What are DOT tokens?
- DOT tokens are the native cryptocurrency of the Polkadot network and play a central role in the functioning and governance of the Polkadot ecosystem. As a multifaceted digital asset, DOT serves several key purposes within the Polkadot ecosystem.
- Governance: DOT holders have governance rights, meaning they can participate in the decision-making process for the Polkadot network. This includes voting on proposed protocol changes, such as upgrades and network parameters. This governance model is a fundamental aspect of Polkadot’s community-driven approach, ensuring that the network evolves in response to the interests and needs of its users.
- Staking: Polkadot operates based on a Nominated Proof of Stake (NPoS) consensus mechanism. DOT holders can stake their tokens to support network security and operations. By staking DOT, holders can become validators or nominees (validator support) on the network. This process is important for securing the relay chain, validating transactions, and creating new blocks. Stakers are incentivized for participation through staking rewards.
- Bonding: DOT tokens are used for “bonding” to connect parachains to the Polkadot relay chain. Projects that want to launch a parachain must lock up a certain amount of DOT while maintaining network connectivity. This combination ensures that the parachain has a vested interest in the health and security of the network.
- Promotes interoperability: DOT, the main currency of the Polkadot network, is used for transactions and interoperability features. This helps facilitate a variety of operations across Polkadot’s interconnected blockchain ecosystem.
- Network Fees: DOT is used to pay transaction fees on the network, which prevents spam transactions and contributes to the overall stability and efficiency of the Polkadot system.
