Polkadot is a next generation blockchain that sets out to establish an ecosystem of cryptocurrencies. It incentivises a global chain of computers to operate a blockchain and is thought by many to be one of the most innovative projects in the world of cryptocurrency. Polkadot's native coin (DOT) was initially conceived in 2016.
The DOT token became available in the summer of 2020 and was founded by Gavin Woods, co-founder of Ethereum. Woods invented the language used by developers when they write decentralised applications on Ethereum. Polkadot is still relatively new but has raised a significant sum of money from investors through the sale of DOT cryptocurrencies.
