Polkadot Coin and Token

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.
