What is Polkadot (DOT)?


A protocol called Polkadot connects blockchains, enabling the transfer of wealth and data between previously incompatible networks (Bitcoin and Ethereum, for example). It is also intended to be quick and flexible. For staking and governance, the DOT token is utilised; it can be purchased or sold on Coinbase and other exchanges.

 Like many post-Bitcoin cryptocurrencies, Polkadot is both a decentralised protocol and a token that can be purchased or traded on exchanges like Coinbase.

The Polkadot protocol is made to securely connect unconnected blockchains so that value or data can move between, instance, the Ethereum and Bitcoin blockchains without the need for a middleman. Through the use of numerous parallel blockchains, often known as “parachains,” that offload much of the processing demand from the primary blockchain, it is also intended to be quick and scalable.

Within the Polkadot network, the Polkadot token (DOT) has two main uses: it is a governance token that gives owners a say in the protocol’s direction and it is used for staking, which is how the Polkadot network verifies transactions and generates new DOT. On exchanges like Coinbase, you can buy and sell DOT as part of your investment plan.

How is Polkadot structured?

The Polkadot network consists of several user-created parallel chains (sometimes known as “parachains”) in addition to a main blockchain known as the “relay chain.” It also contains a connecting layer, or “bridge,” that enables value and data transfers between the majority of blockchains and can even be used to link to databases that are not decentralised ledgers.

How does Polkadot work?

Because so many parachains help the main relay chain with a lot of the heavy labour, Polkadot is able to analyse all of this data. As a result, compared to around 7 for Bitcoin and 30 for Ethereum, the Polkadot network can execute more than 1,000 transactions per second. Polkadot should become more faster as the network expands and more parachains are added, with rates that might reach a million transactions per second.

Or, to put it another way, the relay chain is in charge of achieving consensus and transaction delivery… among parachains, according to the infrastructure specialists at Bison Trails. Within the Polkadot network, there exist application-specific blockchains called parachains. With its own logic and features, each parachain is a whole blockchain unto itself.

How does staking work on Polkadot?

As opposed to the proof-of-work system used by Bitcoin, Polkadot uses a proof-of-stake consensus mechanism to protect the network, validate transactions, and create and distribute additional DOT. DOT holders can interact with the staking mechanism in a variety of ways, depending on how much time, money, and technical expertise they choose to invest.

The most effort is done by the validators; it is time-consuming and technical in nature. You must maintain a node (one of the computers that makes up the network) with little to no downtime and stake a sizeable portion of your own DOT in order to become a validator. You gain the ability to approve valid transactions, add new “blocks” of transactions to the relay chain, and potentially establish DOT while also receiving a cut of transaction fees and tips in return. (On the other hand, you may lose some or all of your staked DOT because to malevolent behaviour, an error, or even technical difficulties.)

Regular investors might indirectly engage in staking through nominees. You can assign a portion of your DOT to a validator you know will follow the rules. You receive a portion of the DOT that your selected validators earn in return. Choose carefully since if your validator violates the regulations, you could lose some of your stake.
Additionally, there are two specialised positions that often ask for less dedication than serving as a complete validator but greater technical proficiency than a nominator: The relay chain validators receive valid parachain transactions from collators, who keep track of them. Fishermen aid in identifying and reporting inappropriate behaviour across the network.

Any of the jobs mentioned above may allow you to stake and participate in the network in order to be eligible for DOT awards. Holders of DOTs can vote on proposed software changes and participate in network governance.
