Do you have an idea for a startup and don't want to pay for scaling it up? Forget about bandwidth problems, servers to install and pay for, with the power of IPFS and the blockchain. In this talk, we will explore how to build an HTML5 DAPP (distributed application) with EmbarkJS, and figure out how to rethink servers, storage, messaging, data and payments in a distributed and decentralised way with the help of Ethereum's smart contracts and IPFS distributed storage.

- When we look back over our 20-year history and think about what has made - and continues to make - our clients so successful, we come up with two key themes that we think have made all the difference. (1) They think big and go after hard problems with big payoffs. They want to lead - not just maintain status quo. (2) They’re not afraid to disrupt their industry, and often to disrupt themselves internally. They go after big things, and they take a bold and completely different approach to getting there. And they tell us that they choose as a partner because we also fit this description.
