Polkadot is the leading layer-0 network – that is, a blockchain whose primary purpose is to facilitate transactions between different blockchains.
Polkadot does this by allowing the creation of secure “parachains” that allow you to conduct transactions between blockchains (i.e. Ethereum and Solana). Users use DOT, the native token of Polkadot, to reserve private space on these parachains. When the transactions are completed, the parachain automatically finalises them on their native blockchains.
DOT is also used as a governance token, giving users the ability to vote on changes to the protocol and is distributed to those who stake their tokens to secure the network.
You can store your Polkadot in a hardware wallet or on a crypto exchange. Hardware wallets allow you to store your crypto offline in a unit that only you have the password for. Exchanges such as CoinJar, keep more than 90% of our crypto in cold storage or private, multi-sig wallets and offer our users next-gen 2FA account protection as default.
Polkadot was created by Gavin Wood (a co-founder of Ethereum), Robert Habermeier and Peter Czaban.
You can buy Polkadot in the UK is through a crypto exchange like CoinJar.
Yes – with CoinJar Instant Buy you can buy Polkadot with any UK-issued Visa or Mastercard. We also offer support for Apple Pay and Google Pay.
The price of DOT in GBP is determined by the international Polkadot market – basically, the price to be found on cryptocurrency exchanges in the UK and all around the world.
Unlike Bitcoin, Polkadot does not have a maximum supply. New DOT tokens are issued to people who stake their DOT to help secure the network at a rate of 10% per year. This means Polkadot is an inflationary currency. There are currently around 1.2 billion DOT tokens in existence.
