Right now, all blockchains exist in isolation. Blockchains compete for which blockchain is the "best" one. But what if all the blockchains could be connected and could interact? The data and tokens on one blockchain could be used on another. Imagine if you could pay for computation using Bitcoin to use a smart contract on Ethereum, or if an Ethereum smart contract could be used to privately hold and distribute Zcash? This is only possible with true interoperability where data-exchange between chains is possible. This is the vision behind Polkadot.

In his presentation, Fabian Schulz will discuss Polkadot as well as Substrate, a blockchain-building framework capable of creating app-specific blockchains in minutes that come preconfigured to access Polkadot’s security and blockchain network.
