For developers interested in building blockchain products, simply investing time in the technology is not enough. The blockchain stack comprises business logic integrated deeply into the technology models. As a result, an introductory level of familiarity with frameworks that formally describe the components of a startup and how to build a company around a product is necessary. This chapter begins with lean methodology, a model created by Eric Ries that relies on three core principles: 1) transform the most basic version of your idea into a product that a customer can interact with; 2) talk to your potential customers early and often; and 3) iterate over that basic model with feedback from your customer to achieve a full product that aligns with customer needs. And we keep in mind this quote from Eric: “As you consider building your own minimum viable product, let this simple rule suffice: remove any feature, process, or effort that does not contribute to the learning you seek.” Then, we present the business-model canvas that breaks down lean methodology into nine applicable components. In addition, we talk about Geoffrey Moore’s approach to product-market fit for high-risk, high-reward technologies. Following this discussion, we present three models to help determine whether your organization can benefit from using a blockchain. Once a decision has been reached on using a blockchain, the Hyperledger Project provides multiple options for enterprise-grade blockchains that can be customized and deployed. Finally, we end the chapter with a brief overview of Hyperledger Composer and the templates it provides for capturing business logic.
