What is Polkadot (DOT)?

What is Polkadot(DOT)?

Polkadot is a next-generation blockchain protocol that combines several blockchains into a single network to significantly simplify cross-chain communication and interoperability. This network is protected by a shared security system: the GRANDPA (GHOST-based Recursive Ancestor Deriving Prefix Agreement) consensus algorithm designed specifically for the Polkadot. Polkadot’s genesis block was launched in May 2020 by Gavin Wood, co-founder and former CTO of Ethereum.

In isolation, blockchains can only handle a small amount of traffic. Polkadot is a sharded multichain network, which means it can handle several transactions on multiple chains concurrently, removing bottlenecks that existed on legacy networks that handled transactions one at a time. Polkadot aims to eliminate slow communication between public and private blockchains, as well as to facilitate a network without forking and jeopardizing scalability.

Its ultimate goal is to function as a framework for all blockchains that opt in. The concept is to handle the messy and expensive cryptocurrency mining processes (such as transaction validation and security protocols) so that developers can concentrate on developing dapps and smart contract features.

How does Polkadot work?

Using a system of public and private key cryptography, Polkadot allows funds to be sent from one digital wallet to another. The private key serves as a password, authorizing and broadcasting transactions to the network, and the hash of the public key is the address you send out to collect funds. These pending transactions are validated in a block of transactions every six seconds or so.

The Polkadot network’s most important components are the Relay Chain, Parachains, Parathreads, and Bridges.

Polkadot’s network is built on relay chains, which serve as the primary communication hub between parachains. Transactions from the parachains are validated on the Relay Chain using a system of validators.

Parachains are self-contained, personalized blockchains that operate on top of the Relay Chain. Each parachain can serve a specific role in the network, ranging from decentralized finance (DeFi) to use cases that require high transaction throughput or privacy gaming, and may be public or private. The system enables the parachains to interoperate, which means they can interact with one another. However, since there will be a finite number of parachains in the network (and the number will grow in the future), there will be a system of public auctions in which parachain candidates will bid to receive their own place.

Parathreads are similar to parachains in that they only occasionally create a connection to the relay chain, allowing for “pay-as-you-go” protection. From a technological perspective, parathreads are somewhat close to parachains; but, from an economic standpoint, they are very different. To become a member of the network, parachains must participate in auctions. The parathread slot, on the other hand, can be leased almost instantly and for a limited time.

Bridges allow Polkadot to communicate with other networks, such as Bitcoin and Ethereum, and allow token transfers between Polkadot and other networks.

What issues does it address?

The two most pressing problems for blockchain-based networks are scalability (the amount of transactions per second the network can handle) and governance (how the group handles protocol updates and changes). Polkadot intends to address all of these issues.

What’s unique about the DOT blockchain?

There may be several reasons for developers to explore the Polkadot ecosystem. Because of the limitations of existing blockchains, it is clear that a few key issues must be addressed: scaling, customization, interoperability, governance, and upgradeability.

Scaling

Some scaling issues stem from the fact that in most blockchains, each node in the network must process all transactions one by one. However, this is not the case with Polkadot; parachains got their name from the fact that they will run and generate their blocks in parallel, while validators will take care of the rest — significantly increasing the network’s pace.

Customization

Polkadot, unlike most other blockchains, allows for extensive customization. It is very easy to deploy parachains for different purposes: you can deploy one parachain in the Polkadot that will serve as file storage, another chain that will provide decentralized identity management, and another for enabling payments in the entire ecosystem by creating a secure coin.

Interoperability

Polkadot networks and applications can exchange information and features in the same way that software on a smartphone can, without relying on centralized service providers with dubious data practices. Unlike previous networks, which mostly functioned as standalone environments, Polkadot allows for interoperability and cross-chain communication. The Cross-Chain Messaging Protocol (XCMP) allows parachains to send any kind of message. The shared security model, in conjunction with XCMP, offers a trustless environment for verifiable message transmission, paving the way for true interoperability.

Governance

Polkadot communities govern their networks as they see fit, and they have a stake in the future of Polkadot network governance as a whole. Teams can tailor and refine the governance of their blockchain to their specific needs, play with new concepts, or swap in pre-built modules for faster deployment. When needs and requirements change, blockchain governance models can be improved and updated.

Upgradeability

Polkadot makes it incredibly simple to update individual parachains. Forks can wreak havoc and divide communities (just ask Bitcoin and Ethereum). Polkadot can add new features, address bugs, and update without forking. Instead, the native chain can be upgraded without difficulty.

The Polkadot Token

Polkadot, like most other blockchain infrastructure ventures, has its own native token. It is known as DOT and acts as the network token, just as ETH is the Ethereum token and BTC is the Bitcoin token.

The current circulating stock of DOT is close to 900 million, and unlike most other cryptocurrencies, it has an unlimited supply. This is intended to incentivize the network and dynamically adapt based on user staking participation rates, inflating up to 10% per year. These tokens are primarily used to reinforce network links, staking, and enabling Polkadot’s governance and upgrades.

This token has a variety of applications. To begin with, it grants token holders governance rights over the entire Polkadot network. This involves deciding on network fees, voting on total network enhancements, and deciding whether to deploy or remove parachains. Holders of this token can vote on future code updates, which will then be automatically upgraded across the network if a consensus is reached.

Despite its recent launch, DOT can already be purchased and exchanged on a wide range of prominent cryptocurrency exchange platforms, including Binance and Kraken.

Recent developments of DOT

Polkadot’s mainnet debuted in May 2020 and rapidly gained popularity among investors, developers, and cryptocurrency traders. It has already racked up a host of remarkable accolades and advances in less than a year, including:

  • Rising to become the fourth largest cryptocurrency, with a peak market capitalization of nearly $18 billion.
  • Redenomination, with old DOT tokens being split 100 ways to create new DOT tokens, increasing the supply from 10 million to 1 billion.
  • Getting rebranded by design firm Koto, who is soliciting community feedback through the Polkadot Brand Bounty Program.
  • There has been a significant increase in developer participation, with over 340 projects now actively being built on the platform.
