How Does Polkadot Work?

Polkadot's multi-chain technology reshapes the blockchain ecosystem by solving the problem of interoperability between different distributed ledgers. Traditionally, isolated blockchains struggle to communicate and share information seamlessly. However, Polkadot enables these otherwise disconnected blockchains to transfer information in a trust-free manner.

The Polkadot protocol enables the connection of public and private chains, permissionless networks, oracles, and future technologies. It allows these separate blockchains to share information and transactions securely through the Polkadot Relay Chain.

The four core components of the Polkadot platform work in unison to achieve this interoperability.

Relay Chain

The Relay Chain serves as the central hub, facilitating consensus and interoperability between multiple blockchains. It ensures that all connected blockchains can communicate and transfer data securely.

Parachains

In addition to the Relay Chain, Polkadot introduces Parachains, which are independent chains that connect to the Relay Chain. Parachains allow different blockchain systems to preserve their unique features while benefiting from the shared security and interoperability provided by Polkadot.

Parathreads

Furthermore, Polkadot incorporates Parathreads, which provide flexible connectivity options for blockchains that do not require a full-time connection to the Relay Chain. Parathreads allow blockchains to access the Polkadot network intermittently, offering scalability and cost-efficiency.

Bridges

To expand the network's reach, Polkadot also employs Bridges that connect parachains and parathreads with external blockchains. These Bridges enable cross-chain communication, enabling Polkadot to integrate with and leverage the features and resources of other blockchain networks.

Polkadot (DOT) History

Polkadot, founded in 2016 by Gavin Wood, who was also a co-founder and CTO of Ethereum, aimed to address the limitations that Ethereum could not overcome. Wood's vision was to create a new multi-chain ecosystem that would function as a bridge to other blockchains. In Gavin Wood's view, the purpose of Polkadot was to address certain limitations of Ethereum, such as scalability, interoperability, and governance.

Polkadot aims to provide a scalable and secure platform for building decentralized apps that can interact with each other and other blockchains, enabling a more interconnected and efficient blockchain ecosystem.

To bring this vision to life, Wood drafted the Polkadot white paper in October 2016. The white paper outlined his plans for a decentralized platform that would allow different blockchains to communicate and share information seamlessly.

In 2017, Wood, along with Peter Czaban and Robert Habermeier (they were previously associated with Parity Technologies, a company known for its involvement in blockchain and cryptocurrency development), established the Web3 Foundation.

This foundation would eventually host Polkadot's very first initial coin offering (ICO) in October 2017. During the public sale, Polkadot raised an impressive $145 million by selling half of the total 10 million supply of its native token, DOT. This successful token sale demonstrated the market's confidence in Polkadot's innovative approach to blockchain interoperability.

Building on this success, Polkadot went on to raise an additional $3.3 million in a private token sale in 2020, further solidifying its financial foundation for future development and expansion.

DOT Tokens

The native cryptocurrency of Polkadot is called the DOT Token. It serves multiple purposes within the network, including staking, governance, and bonding (connecting new chains to the network). DOT holders can participate in network upgrades, secure the network, and earn rewards for their contributions. DOT trading is available on numerous crypto exchange platforms, and the digital asset is among the top 20 largest cryptocurrencies in the crypto space by market capitalization.

The Polkadot cryptocurrency has a unique feature of unlimited total supply, with new DOT tokens continuously entering circulation at a fixed annual inflation rate of 10 percent. After its launch in May 2020, DOT reached a maximum price of $6.30, which later fluctuated between $4 and $5 throughout the year. However, in May 2021, DOT's price reached an all time high of $49.80. Another peak of $44.41 occured in October 2021 during the Q4 bull run.

What are Polkadot Use Cases?

Polkadot has a wide range of use cases, including decentralized finance (DeFi), gaming, supply chain management, identity verification, and more. Its interoperability feature allows different blockchain services to communicate, facilitating the seamless transfer of assets and data between various applications.

The Consensus Algorithm of the Polkadot Network

Polkadot is an open-source sharded multi-chain protocol that links and secures a group of specialized blockchains, enabling cross-chain transfer of any data or asset types, not just tokens, thereby allowing blockchains to smoothly communicate with each other. The platform was designed to provide a foundation for a decentralized internet of blockchains, also known as Web3.

The platform uses a hybrid consensus algorithm called "Nominated Proof-of-Stake" (NPoS). This algorithm combines elements of both Proof-of-Stake (PoS) and Proof-of-Authority (PoA). This method is devised to maintain the security, decentralization, and efficiency of the network.

NPoS

NPoS allows token holders to nominate trustworthy validators who are responsible for securing the network and validating transactions. Validators with the most nominations are selected to produce blocks and add them to the blockchain network. This mechanism ensures a fair and decentralized network as token holders have the power to choose validators, promoting participation and accountability within the ecosystem.

NPoS encompasses four distinct roles, each tailored to different user preferences and responsibilities.

• Validators play a crucial role in securing the network. They contribute to the validation process by staking their dot tokens and conducting verifications on the Relay Chain. By ensuring the integrity of transactions, validators help maintain the overall security and reliability of the Polkadot network. Validators receive crypto rewards in the form of a percentage of the inflation of the Relay Chain, as well as transaction fees.

• Collators fulfill an important function by preserving the complete historical record of the Relay Chain and their specific parachain nodes. This historical data plays a vital role in facilitating cross-chain messaging, enabling seamless interoperability and communication between different chains within the network.

• Fishermen act as vigilant guardians against invalid transactions. By operating full nodes of Parachains, they monitor and police the network for any suspicious activities and bad behavior. Their role helps maintain the integrity and trustworthiness of the transactions occurring within the Polkadot ecosystem.

• Nominators, on the other hand, choose a more passive approach. While actively holding dot tokens, they opt not to take on the responsibilities of validators, collators, or fishermen. Instead, nominators decide to stake their tokens, contributing to the network's security and consensus algorithm in a more indirect manner.

These four roles in the NPoS system allow Polkadot to establish a robust and decentralized network, where participants can choose their level of involvement based on their preferences and desired level of responsibility.

GRANDPA

To further enhance the security of the Polkadot blockchain, the GRANDPA (GHOST-based Recursive Ancestor Deriving Prefix Agreement) finality gadget is used. GRANDPA helps to determine the final state of the blockchain, providing confirmation that transactions are irreversible.

It employs a Byzantine Fault Tolerant (BFT) consensus protocol, where a committee of validators collaboratively agrees on the order and validity of blocks, resulting in finality. GRANDPA eliminates the possibility of forked chains and double-spending, making the Polkadot blockchain more reliable.

What Makes Polkadot (DOT) Unique?

Polkadot stands out from other cryptocurrencies and blockchain platforms thanks to its unique features and benefits. Here are some of them:
