TitleRunning Web Assembly Smart Contracts in Fabric
Status

OPEN FOR APPLICATION

Difficulty

MEDIUM  

Description 

WebAssembly (WASM) has slowly become a popular language for smart contract development. One of the key features of the WebAssembly is that different languages such as Rust, Python, C/C++ support compilation to WASM. By integrating WASM into Hyperledger Fabric, chaincode developers will be given a wider variety of languages to choose from when constructing their smart contracts.

The overall goal of this project is to enable this feature in Fabric. We are looking for an intern who is interested in adding this support. He/she will be tasked to come up with a design for the integration and achieve a basic implementation by the end of the internship. As well as integrating WASM, we are also looking for the development of examples as to how this new feature will be used in the workflow the intern creates. We have provided a possible Go implementation of WASM as a possible resource/library, however we are open to the intern choosing a different implementation and chaincode language.

Additional Information

Learning Objectives

  • Learn to work in open source development which includes communicating using open source channels, working with the community to get feedback and help to complete the project

  • Learn good software development practices

  • Learn to communicate and work global teams

  • Learning to design a project/feature end to end

Expected Outcome


  • A chaincode that once installed in Fabric can be used to run Web Assembly Smart Contracts

  • Sample applications/tutorials to go along to use the feature. As a user of this feature I should be able to follow this tutorial to understand end to end.

Relation to Hyperledger 

We want to add this feature to Hyperledger Fabric (https://github.com/hyperledger/fabric).

Education Level

Students in undergraduate programs can apply.

Skills

  • Git/ understanding of source control

  • Go (Preferred), if not then comfortable with languages such as C/C++, or Java

  • Familiarity with unix commands

Future plans

Based on the popularity of WASM we would like to turn this into project/feature we continue and develop in a similar fashion as the fabric-chaincode-evm.

Preferred Hours and Length of Internship

Both full time and part time are okay.
