What is Polkadot

Polkadot is a protocol that facilitates the sharing of data and value between different networks, such as Bitcoin and Ethereum.

Polkadot aims to be fast, efficient and secure. It’s not just a token but also offers its users voting rights, staking rewards, and token-holder governance.

With the DOT token available on Coinbase, people can buy or sell it on exchanges like Coinbase to take advantage of price fluctuations and potential profits.

The DOT token is used for validator registration, identifying network nodes, participating in election cycles for voting on network decisions, staking for incentives from the bonded pool, making deposits to accounts to be able to become an active validator node and governance of the Polkadot protocol itself.

Stakers that run their own validator will earn an income based on transaction fees in addition to rewards derived from their balance held as collateral.

As Polkadot grows in popularity and usage, so too will demand for DOT increase leading to greater circulation over time that can help maintain its intrinsic value at expected levels.

Best Polkadot dApps

There is no one best dApp on Polkadot. Best really depends on your needs, use case, and situation. 

Above this section you'll find a growing list of POlkadot dapps which you can (and should) filter through. 

However, I know it can be a pain to try and sift through all of that so below I've collated a list of some of the most popular dApps built to support Polkadot. 

1. Trustwallet

Multi-chain crypto wallet

Trsut wallet Polkadot dapp homepage

Trustwallet is one of the most popular and trusted wallets out there.

Founded by Viktor Radchenko, it provides a secure and user-friendly wallet that can accept multiple types of assets.

The goal was to make an inclusive wallet accessible to any level of crypto user, regardless of experience or technical ability.

It makes transactions between its integrated decentralized application (DApps) much easier than ever before with PancakeSwap, 1inch and LooksRare being just some of the names included in this list.

The best thing about Trustwallet is how easy it makes things for its users.

Those who own multiple cryptocurrencies can easily store them all in the same spothelping eliminate the need for installing different wallets for every coin they trade with. Furthermore, features such as price charts allow Traders to track prices within the convenience of their Trustwallets without needing to search anywhere else.

Plus, WebWallet integration ensures extra safety features when making transactions from home using Wallet Connect technology. All this comes together to create a comprehensive package that offers a great multi-chain wallet for cryptocurrency owners everywhere.

2. Moonbeam

Cross-chain functionality for smart-contract deployment

Moonbeam polkadot protocol homepage

Moonbeam is a developer-focussed blockchain that enables developers to use Ethereum's existing development tools and network.

It offers an EVM implementation, a Web3-compatible API and bridges to existing Ethereum networks so that developers can build on the Moonbeam platform as they have always done with Ethereum.

To ensure security, Moonbeam also leverages Polkadot's relay chain as a parachain. This allows the Moonbeam blockchain to communicate and merge with other Polkadot-connected chains when this functionality becomes available on Polkadot.

There are two tokens associated with the Moonbeam Network: Glimmer (GLMR) is the network’s utility token, based on the Polkadot network, providing usage of common functions available in Winding Tree such as staking rewards and participation in processes like voting or setting parameters.

Additionally, this token will act as a driver of incentive mechanisms across other features of the Moonbeam protocol such as parachain registration or staking.

In short, Glimmer token holders benefit from increased usability within Moonbeam by gaining access to multiple utilities from potential applications running on it.

3. Firebird (formerly Polkafoundry)

Build Gamefi projects

Firebird (formerly Polkafoundry) allows the creation of borderless, decentralized applications (DApps) and non-fungible tokens (NFTs) using Polkadot's powerful interoperability and scalability features.

Through the platform, developers will gain access to several DeFi-friendly services that help make their DApps accessible to a larger audience.

It appears that the primary focus of Firedird is on the growing Gamefi section in Web3.   

Firebird puts an emphasis on providing a simple user experience when designing its apps and features, in order to encourage greater acceptance by users.

4. Acala Network's Karura

The Defi home of Polkadot

Karura Polkadot dapp homepage

Acala is an Ethereum-compatible platform that seeks to revolutionize financial services tools by taking advantage of the power of smart contracts and native protocols. It not only provides cross-chain compatibility but also ensures a higher level of security than traditional financial procedures.

The Acala platform offers several innovative applications, such as its trustless staking derivative (liquid DOT) and its multi-collateralized stablecoin (aUSD).

Both are highly secure solutions that can be used without risks thanks to Acala's micro gas costs that can be paid with any token.

The cost is linked to the US dollar, so one Acala dollar will always equal one US dollar. In addition, Acala takes pride in being an all-inclusive DeFi hub that integrates MetaMask, Truffle, and Waffle so developers can create a user experience very similar to the one found on Ethereum.

Polkadot Architecture

Polkadot is comprised of a main chain, known as the “relay chain,” and many user-created parallel chains (or “parachains”).

This research-based technology also features a connecting layer, known as the “bridge,” that allows value and data to be transferred between most blockchains.

For example, this bridge can be used to connect Ethereum with Bitcoin or to connect blockchain networks with non-blockchain databases. The benefit of the Polkadot network is that developers can leverage its interoperability capabilities in order to create decentralized applications (dApps).

By leveraging the scalability of each modifiable parachain and assigning certain transactions to specific parachains, the main relay chain benefits from increased throughput.

A crucial part of Polkadot’s protocol are validators that are assigned certain responsibilities depending on their consensus mechanism.

Validators use their computing power to audit transactions both on the relay chain and on all user-created parachains.

It is vital for validators to remain active in order for Polkadot network performance not be disrupted. 

How does Polkadot work?

Polkadot is a revolutionary blockchain infrastructure that allows for the scaling of multiple blockchains all at the same time.

Instead of just one blockchain performing all of the work, it works by using the previously mentioned ‘parachains’ that do a lot of the heavy lifting for the main relay chain.

This means that Polkadot can process significantly more transactions compared to Bitcoin and Ethereum, with speeds potentially reaching up to a million transactions per second.

The relay chain is responsible for achieving consensus within its various parachains.

It also ensures that each transaction on the network is securely delivered to its intended recipient. Along with this, additional data such as validator information and cross-chain messages are delivered as well.

Security is also maintained through mutual checks between parachains and validators, so as to guarantee safe interaction amongst them, resulting in an effective system.

Does Polkadot have a token?

The platform is powered by its own native cryptocurrency, known as the DOT (short for Decentralized Owned Technology) token.

Users must hold the DOT cryptocurrency in order to participate in the network’s voting system, one of Polkadot’s core features. This allows holders to decide on potential code changes before they are approved and implemented across the network automatically once a consensus has been reached.

The DOT coin can also be used to incentivize activities such as validating transactions or managing data availability within the ecosystem.

Over time, several new services could be added that require DOT payments in exchange for access.

Developers and users alike have already recognized Polkadot for its abilities to create larger scalability than what traditional chains offer. All this positively contributes toward increasing token usage and values over time, creating a unique value exchange system between participants across multiple ecosystems.
