Polkadot is a heterogeneous multi-chain interchange and translation architecture that enables customized side-chains to connect with public blockchains. The protocol was created by the Ethereum co-founder Gavin Wood. Polkadot's first token sale closed on October 27, 2017, raising a total of 485,331 ETH (Ether, the currency of the Ethereum blockchain).The technology surrounding Polkadot is set to help support the decentralization of the web, a concept pioneered by Dr. Wood and coined ‘Web 3.0’. The subsequent innovations that followed Polkadot were Substrate, a framework to efficiently build your own blockchains; and the “canary” Kusama network that is independent of Polkadot but runs on early, unaudited versions of the same software as a proving ground for bleeding-edge technology.At Cryptoknowmics, you can find all the information you need on Polkadot that can help you with its sale and purchase.
