11 Blockhead Server Implementation of the Open Service Broker API Automatically does most of the heavy lifting for you 11

12 Open Service Broker API App developers want to use blockchain App devs should focus on writing apps We want to deliver this functionality in an easy to use way OSB API 12

13 Open Service Broker API Open standard for the provisioning and management of cloud services in relation to a cloud platform Any service that can be decomposed into the OSB workflow can be provisioned as a OSB service Once a broker is subscribed to your platform, can be utilized easily be end appl developers Current implementations for Cloud Foundry, Kubernetes 13

14 Blockhead Automates the deployment and use of a blockchain node Currently supports Etherium Deploys and syncs an Etherium node Creates an account on that node Compiles and applies a smart contract you specify Returns the Application Binary Interface for your use Plan to add support for Hyperledger Fabric 14

15 Blockhead - 2 Simple Steps 1. Create Service 2. Bind Service (with contract URL) 15
