Welcome to Streamr’s Marketplace, which was first launched as an MVP at Consensus 2018. In this blog post (part of a set of three), I’ll be taking you through what is needed to create a realtime data product for the Marketplace. This tutorial requires no technical knowledge, but you will need to have set up a few things that do require some technical heavy lifting.

What you will need

For this initial version of the marketplace, you will need a Streamr account, and you will need to be signed in. You can create one here if you don’t have one yet. You will need to have added the data streams you plan to package into a product to your account. For more information on that, please refer to parts one and two of this tutorial series.

You will also need an Ethereum wallet address, and a small amount of Ether, in order to pay the gas fees required to publish your product to the Marketplace. While explaining everything around buying Ether and setting up a wallet is a bit beyond the scope of this tutorial, Metamask is a relatively easy to use wallet that plugs into Chrome, and could be considered the best way to interact with the Streamr Marketplace for now.

You will also need a cover image for your product, that will be displayed as a tile in the main Marketplace view, and seen as a cover image in the Product detail page. The image should be around 1000 x 800px in size in order to work nicely on retina displays, though typically it will be shown at smaller sizes than this.
