Polkadot is a layer one blockchain, a foundational blockchain on which blocks are produced and its native cryptocoin the “DOT” is used to pay transaction charges and reward those that safe the community.
One in every of Polkadot’s predominant targets is to make connections between totally different networks corresponding to Cardano, Solana and essentially the most identified Bitcoin and Ethereum.
Earlier than going into additional particulars, let’s dive into its historical past and learn how and when Polkadot was created.
Polkadot’s historical past
The primary version of Polkadot’s white paper was printed on the finish of 2016 by Gavin Wooden and that’s the place it began.
Gavin Wooden can be the cofounder of Ethereum and one of many predominant creators of the programming language of Ethereum’s good contract : Solidity.
A while after, he will get joined by Robert Habermeier and Peter Czaban, the 2 cofounder of Polkadot.
The event of Polkadot is supervised by an organization primarily based in Switzerland whose mission is to « ship a Internet 3.0, a decentralised and truthful web the place customers management their very own information, identification and future ».
How was it financed ?
Polkadot, like a lot of the cryptos, was financed by a number of ICOs (preliminary coin providing), which is thru the sale of pre-mined tokens.
The primary occurred in October 2017 and raised 140 million {dollars} in ethereum. Two different gross sales will likely be made in January 2019 and July 2020 to boost an extra 100 million {dollars}.
How does the blockchain works ?
Gavin Wooden’s mission is without doubt one of the most intricate crypto mission to clarify, however I’ll attempt my greatest !
The community consists of a base layer known as the « relay chain » on which different parallel networks (A, B, C,D…) are linked to it. These could be of a number of sorts.
To start with, there are the parachain and their quantity on the Polkadot community is restricted to 100 in keeping with the most recent information.
It’s much like Bitcoin and Ethereum the place the customers struggle by an public sale system to see their transactions included within the subsequent block. Within the case of Polkadot, it’s the networks and the blockchains which are making an attempt to attach themselves to the relay chain. They compete in opposition to one another to accumulate a spot within the Polkadot community. The mission with essentially the most DOTs wins.
Changing into a parachain isn’t a simple factor as a result of its comparatively costly, some initiatives shouldn’t have the required funds, that is why the group accountable for Polkadot has discovered one other various: the Para threads.
Para threads are extra versatile Para threads : the blockchain community has no non-public connection, as a substitute charges are paid solely when the relay chain is used.
Lastly, the final factor that may connect with the relay chain are “bridges” which permit the parachains to speak with the opposite exterior blockchains like Bitcoin, Solana…
What’s the consensus mechanism utilized by Polkadot ?
The consensus mechanism utilized by Polkadot is the nominated proof of stake however there are few specificities distinctive to Polkadot.
As a reminder, proof of stake consensus works by locking your tokens within the blockchain with a purpose to validate blocks.
Extra tokens you will have locked, the upper odds to validate the subsequent block, you might be then rewarded by gathering a portion of transaction charges and a small quantity of DOTs.
Within the case of Polkadot’s community, there may be an extra degree, holders of DOT can hand over their tokens to validators that they belief and to validate transactions.
To turn into your personal validator, it’s good to possess a minimum of 350 DOTs and your capital must be freezed within the protocol for 30 days.

Do you have to purchase DOT ?
Even when there’s a actual must hyperlink the parallel growing ecosystems, there’s nonetheless an extended solution to go by way of improvement for Polkadot.
Parachains have been launched just lately, and there are lower than a dozen actually operational. There are only a few transactions on the Polkadot community, round 13 000 per day, as a comparability there a 1 Million on Ethereum.
Despite the fact that, Polkadot’s mission is growing quickly, it stays nonetheless marginal in comparison with its opponents : BNB & Solana have round 10 billion of TVL (complete worth locked) whereas Polkadot has only one billion. Let’s not even discuss Ethereum that’s round 100 billion.
Regardless of Polkadot’s opponents being forward of its mission, we should always nonetheless control it. Polkadot remains to be very younger and promising, it certainly has a vibrant future forward of it.
