Abstract
Hyperledger Iroha 1 is blockchain implemented in C++. To interact with Irohas' nodes (perform commands and queries) there are few client libraries - iroha-python, iroha-javascript, iroha-java, iroha-ios. Despite the fact that Iroha has implemented iroha-cli in C++ there is no client library in C++. What is more iroha-cli is deprecated and not all commands are fully supported.
The internship project in short words is to refactor iroha-cli and extract from its iroha-cpp library. Using the library would require project of entire library (inspiration are rest of libraries).
Optionally the library should be compatible with C language (extern "C") to make it easy to use the library from multiple programming languages.

Timeline
Dates | Tasks/Plan | Status |
|---|---|---|
| June 1 - June 14 | Getting familiar with Iroha documentation and starting example database. Building and running Iroha from code. Mentee intro with the mentor. Introduction to the concepts of Hyperledger Iroha 1. Build and run Hyperledger Iroha node (Irohad) and Iroha-cli from source. Send sample commands and queries via Iroha-cli with succeed. | Done |
| June 15 - June 28 | Send sample command and queries via Iroha-Python and Iroha-Java library. Reading Iroha code. Getting familiar with iroha transactions, queries and statuses. | Done |
June 29 - July 12 | Design interface of Iroha-cpp library. | Done |
| July 13 - July 26 | Start implementing iroha-cpp library. Introduce working draft/concept of the interface. Resolving current issues. | Done |
| July 27 - Aug 9 | Refactor current implementation. Possible contact with the iroha developers on monthly meetings in order to verify current progress, design and approach of the implementation. Create a separate directory/module for iroha-cpp client library in iroha main repository. Independence from iroha transaction/query/status implementation. Implement own methods in order to handle auto-generated protobufs. | Done |
| Aug 10 - Aug 23 | Implement grpc client in order to send a transaction/query/status to the iroha server. Create a separate repository (iroha-cpp). Create first PR to review. | Done |
| Aug 24 - Sept 6 | Working on newly created pull request. Improvements/refactoring/testing. | In progress |
