Are you passionate about blockchain and eager to impact the field? Ready for a structured, hands-on opportunity to learn the ropes of open source development? Looking for a pathway to develop source code, documentations, and research skills while helping to advance open source projects and communities? Then you should apply for the annual Hyperledger Mentorship Program.

Now in its 8th year, the Hyperledger Mentorship Program matches aspiring contributors to the community, at any stage in their career, with experienced mentors to work on real-world projects in the Hyperledger ecosystem. The mentors design their projects to match their expertise and help meet critical development milestones. Mentees are not only introduced to open source development infrastructure, tooling, and culture, and best practices, but they walk away from the project with tangible work product and valuable contacts. 

Mentees can tackle their projects from anywhere in the world and will receive a stipend. Mentors are active members of the very global Hyperledger community and, likewise, will work on these projects from locations around the world. 

Over the years, this program has helped fast track careers for mentees and mentors but also pushed ahead existing and new Hyperledger projects and programs. It’s been a great on-ramp for new contributors and community leaders. 

A number of former mentees are serving as mentors for this year’s project. Below, a few share their perspective on the experience and ongoing engagement with the Hyperledger community and Mentorship Program:

"The Hyperledger Mentorships offer a unique opportunity to learn and grow, connecting individuals worldwide with invaluable guidance and support from experienced mentors.

Hyperledger Fabric CC-Tools Support for Fabric Private Chaincode

Project Title: Hyperledger Fabric CC-Tools Support for Fabric Private Chaincode

Primary Focus: Coding, Documentation, Research

Fabric Private Chaincode (FPC) leverages modern Confidential Computing technology, such as Intel SGX, to enhance the protection of chaincode and their data while executed at the endorsing peers. Client applications interact with their private chaincode via the FPC Client SDK, which is responsible to encrypt and authenticate the invocation arguments before being sent to the endorsing peers. Currently chaincodes can be developed in C++ or Golang.

The Hyperledger Labs CC-Tools library offers several features that facilitate the journey of learning, development and deployment of chaincode for Hyperledger Fabric in Golang.

The goal of this mentorship project is the design and the integration of FPC as a destination for the code developed using CC-Tools. This also includes the creation of appropriate samples and documentation. The project requires a solid understanding of theory and practice of software development using Golang, distributed systems, and security. During the project you will get hands-on experience with the development of Hyperledger chaincode, the deployment of Fabric networks, the transaction lifecycle, and Confidential Computing technology.

Hyperledger Cacti: Core Operators Modules for DLTs

Project Title: Extensible Library and API for Core Interoperability-Enabling Ledger Functions

Primary Focus: Coding, Documentation, Research

Hyperledger Cacti provides modules, toolkits, and protocols to enable networks built on distributed ledgers to interoperate and carry out transactions spanning their boundaries, such as asset transfers, asset swapping, and ledger data communication. The protocols enabling such transactions as well as more complex use cases require certain basic capabilities or building blocks that every distributed ledger or blockchain technology (e.g., Ethereum, Corda, Hyperledger technologies like Fabric, Sawtooth, Iroha, and Besu) can support, though using specific and distinct implementations. These capabilities, or core operators, include the ability to lock or freeze assets for a given time period, claim or unfreeze assets by a deadline, generate and verify proofs of ledger state authenticity, and access control. They also include, at a basic level, the ability to write or query a ledger and its transaction log, using the native modes supported by a given DLT, (e.g., UTXO spending, smart contract interfaces).

For ease of building DLT-agnostic protocols in Cacti, we need to build modules corresponding to various DLTs supported by Cacti that implement these core operators and expose them using a standard API. These modules, which will be engineered as smart contracts or distributed applications according to the native development style for a given DLT, will be deployed on the networks that seek to interoperate with others, and can be invoked on demand by the connector plugins and business logic at higher layers in Cacti.

The goals of this project are as follows:

  1. Design and build DLT-specific core operator modules for Cacti by leveraging existing Cactus or Weaver packages. This involves identifying building blocks of unique features in either, and integrating legacy Cactus and Weaver packages wherever they offer a common feature.
  2. Design and implement a common DLT-agnostic API, following the OpenAPI standard, using which any DLT-specific core operator module can be invoked by application-specific business logic on-demand.
  3. Add suitable API support within the common Cacti client API for ease of application development
  4. Do a research survey of existing blockchain/DLT literature to identify a potentially exhaustive set of core operators any DLT network must possess (or harness) to interoperate with other networks.
