What is a Polkadot token?
Polkadot Tokens (DOTs) are network native tokens. Polkadot is a blockchain protocol that 
guides global computer networks as an incentive and allows users to launch and operate 
blockchains.
Currently, the DOT circulation supply is approaching 900M, and the maximum supply of 
Polkadot coins has not been determined in advance. These tokens are primarily intended 
to strengthen network connectivity and activate Polkadot's governance and upgrades.
What are the unique features of the Polkadot blockchain?
● Polkadot operates two types of blockchains by design. A basic network (relay chain) 
and a user network (parachain).
● The difference between them is that the transactions on the relay chain are permanent. 
Conversely, parachains are customized for a variety of uses and supplied to the main 
blockchain.
● Polkadot's unique design allows you to keep your transactions secure and accurate by 
using only the computing resources needed to run the main chain.
● At the same time, DApps development it has the advantage that users can customize 
many parachains for many different uses.
● Visualization material is Polkadot's unique multi-chain framework shown in the white 
paper.
An overview of the structure and components of Polkadot.
● Bridge:  A promoter between parachains, parathreads, and other blockchains.
● Parachain : An independent chain that allows you to form your own tokens.
● Parathread:  Provides a flexible model that leverages independent chains to form 
new tokens.
● Relay Chain:  Facilitates consensus between different chains.
Overall, the Polkadot blockchain allows users to make transactions more personally and 
efficiently. This is because the blockchains they create do not expose user data to the 
shared network. Gavin Wood said it could theoretically handle more than one million 
transactions per second. DApps Development Services
The beginning of polkadot coins
● Polkadot was first launched in 2017 with an ICO donation of $ 140 million. In addition, we 
made two private sales in 2019 and 2020, raising an additional $ 100 million. 
● However, due to the vulnerability of Parity's Ethereum wallet, hacking that contains about two-
thirds of the ICO tokens that were previously frozen has occurred, and the frozen tokens have 
not been recovered to date.
● Surprisingly, the team behind Polkadot decided to proceed with this project despite these 
losses.
● In August 2020, Polkadot began allowing investors to trade the remaining tokens. As a result, 
DOT has been listed on many major exchanges such as Finance, Huobi and Kraken. Market 
capitalization surged due to high volume.
● Currently, Polkadot Coin (DOT Token) has a market capitalization of over $ 7 billion and is 
ranked 7th on the cryptocurrency market capitalization list.
How does Polkadot staking work?
● In order for you to know what a Polkadot coin is, it is essential to understand its purpose and 
function. DOT cryptocurrencies play a decisive role in maintaining and operating the Polkadot 
blockchain.
● Users who own a DOT and have an equity stake can vote for network upgrades.
● Each vote is proportional to the amount of money the user has stakes on the DOT 
cryptocurrency. As of 2020, DOT has an annual staking rate of 10% to 15% on exchanges 
such as Kraken and Bitfinex.
● To encourage staking, Polka Dots will be compensated by the newly issued DOT, depending 
on how many tokens the user has stakes. The Polkadot blockchain has four consensus roles, 
all of which are covered.
● Validators:  The person who holds the relay chain by staking the DOT and validating 
the proof.
● Nominators:  Protect your chain by arranging the Validator list short and staking the 
DOT for work reliability.
● Collectors:  Keeps most shads. They collect shard transactions from users and 
produce proofs for Validators.
● Fishermen:  These monitor network activity and report suspicious activity to 
Validators.
Staking is one of the three main uses of DOT tokens, apart from the basic transactions for 
governance and bonding. Parachains within the Polkadot network are public blockchains, 
private blockchains, or other data sources. Parachain data is accessed through special 
nodes and sent to Polkadot, similar to how distributed Oracle operates. Parachains are 
activated by staking DOT tokens and removed from Polkadot by unstaking.
