To untangle Polkadot’s role in crypto, it is important to start understanding that Polkadot is a blockchain platform that enables different blockchains to communicate and share information with each other, creating an interconnected network. It is actually often described as a “blockchain of blockchains.”
Polkadot is a decentralized network that aims to connect and secure different blockchains. It provides a framework for developers to build their custom blockchains while benefiting from the security and interoperability of the underlying network. As a result is often described as a “blockchain of blockchains”.
As of 2024, Polkadot is highly relevant in the blockchain ecosystem due to its modular framework.
This article will cover Polkadot’s role in the ecosystem, its main elements, how it works, use cases, and its benefits and challenges.
Polkadot’s Role In The Blockchain Ecosystem
Dr. Gavin Wood, one of the co-founders of Ethereum, Robert Habermeier, and Peter Czaban worked on creating Polkadot for years. In 2017, the Web3 Foundation, co-founded by Wood, held an initial coin offering (ICO) that raised approximately $144 million to fund the development of Polkadot’s project.
Despite a setback when $90 million worth of funds were frozen due to a Parity wallet vulnerability, the project continued with the remaining resources and later held another funding round. Polkadot had its initial block, the genesis block, in 2020.
Polkadot mainnet version is referred to as Polkadotv1 and was focused on the main architecture of the project. Polkadot 2.0 results from many upgrades and a more mature network stage.
Polkadot allows a wide range of blockchains to interoperate because it works on a blockchain protocol that facilitates the cross-chain transfer of any data or asset type, not just tokens. This allows for the creation of specialized blockchains (parachains) that connect to a universal network (the Relay Chain).
Core Components Of Polkadot
Polkadot works with three specific components that make it unique: the relay chain, parachains, and bridges.
Relay Chain
- This is Polkadot’s main blockchain that coordinates the system, handles interoperability, and provides shared security.
- Polkadot uses a consensus mechanism called nominated proof-of-stake (NPoS)
- NPoS ensures the integrity of the blockchain. It also provides a decentralized governance system and validates transactions.
Parachains
- These are independent blockchains connected to the relay chain, and each of them can have their own tokens.
- Polkadot’s parachains provide customizability and scalability.
- For example, a parachain can specialize in identity verification while another one specializes in real estate transactions.
Bridges
- Bridges are special parachains that allow Polkadot to connect and communicate with other blockchains like Ethereum.
- As a result, they facilitate interoperability and expand the network’s capabilities, like cross-chain communication and asset transfer.
How Polkadot Works
According to its official website, Polkadot is “a network governed by a rebelliously innovative community.” Its native token DOT plays a crucial role in the development and implementation of the network, and it has multiple functions:
- Governance: DOT holders can participate in governance decisions, including determining network fees, auction dynamics, the addition or removal of parachains, and changes to the protocol.
- Staking: Involves locking up DOT tokens to support network operations and integrity. Validators and nominators are selected based on the amount of DOT they stake. Stakes also help secure the network and earn rewards.
- Bonding and parachain auctions: In Polkadot, new parachains join the network through a process called parachain auctions. To secure a slot, projects compete in these auctions by bonding (locking up) DOT tokens. The project that commits the most DOT during the auction wins the slot, granting it the right to operate as a parachain for a fixed period, usually up to two years.
- Transaction processing and finality: Polkadot uses advanced mechanisms to ensure quick transaction processing and finality, helping to improve the security of the Relay Chain.
- Scalability and performance advantages: Polkadot achieves scalability by enabling parallel transaction processing across multiple parachains. Each parachain operates independently and can process transactions simultaneously, rather than all transactions being handled sequentially on a single chain (as is the case with traditional blockchains like Bitcoin or Ethereum).
Benefits Of Polkadot
Polkadot’s design offers several benefits that address some of the primary challenges faced by earlier blockchain technologies.
- Interoperability: Enables different blockchains to interact and share information.
- Scalability: Multiple parachains process transactions in parallel, significantly increasing throughput.
- Security: Shared security model where all parachains benefit from the robust security of the Relay Chain.
- Customizability: Developers can create customized blockchains that are tailored to specific needs.
- Ecosystem development: Encourages a collaborative environment for developers, fostering innovation.
Real-World Applications And Use Cases Of Polkadot
Applications range from the most ambitious, like the Internet of Things (IoT) and decentralized finance (DeFi) platforms, which allow for asset trading without intermediaries, to the most specific, like gaming or supply chain management systems.
Decentralized Finance (DeFi)
- Acala Network: A platform on Polkadot that lets users trade cryptocurrencies, earn rewards by staking, and use a stablecoin called aUSD. It is similar to a financial hub for the Polkadot blockchain.
- Moonbeam: This platform makes it easy for developers to build apps on Polkadot. It’s like a bridge between Ethereum and Polkadot, so apps built for Ethereum can also work on Polkadot.
Cross-Chain NFT Platform
- Efinity: This is a para chain designed for NFTs (non-fungible tokens). It attempts to reduce transaction fees for minting and trading NFTs and provide a more scalable and environmentally friendly alternative to traditional proof-of-work networks.
