Warning: this is a prototype that is currently under development by the IBM Blockchain team. As a result, it may dramatically change, have major bugs, completely fail to work, or disappear altogether. There is no officially provided support for this project; any bugs that you report may go unfixed for a longer period of time than you’re comfortable with. If you’re happy with all of that, then please carry on reading! As we work on the project, we’re extremely interested in your feedback about how we could make it better, so please do get in touch. See our Community page for more details.

This starter kit is intended to bootstrap your full-stack development experience building blockchain applications on top of Hyperledger frameworks.

A typical permissionable blockchain application stack has 3 highly coupled layers:

Smart Contracts (i.e. chaincode) for defining business logic as permissionable state transitions within the ledger
REST API Server for exposing a uniform interface to invoke smart contracts with (i.e. web)
UI Interface for creating a sensible user experience (i.e. linking buttons to api endpoints)

There are several tools within this kit which will allow a developer to implement, deploy, and link each layer of this stack.

There are also some sample applications which can demonstrate typical implementations and showcase common patterns.

If you would like to contribute to the kit, check out our contributing guide.

Tools

Toolchains

For each layer of the application stack, we have created a custom bluemix toolchain template. This template configures the relevant development environment with version tracking (cloning from a scaffolding repo) and continuous integration (using our build-test-deploy framework).

Check out the toolchains.

Scaffolding Code

We have created several repositories which can serve as the foundational structure and default configuration for each layer of the stack.

Smart Contract Scaffolding

Fabric: NodeJS
Fabric: goLang
Composer: JS/bna

API Scaffolding

Fabric: Express

UI Scaffolding (WIP)

Coming Soon…

Build Test Deploy Framework (WIP)

We have built a comprehensive build-test-deploy framework for developing smart contracts within Hyperledger frameworks. This framework is used within the delivery pipelines created by the bluemix toolchains in this kit. We are planning on releasing a contained CLI which employs these scripts soon!

Check out the scripting library.
