Blockchain platform Hyperledger Iroha is designed for simple creation and management of assets. This is a distributed ledger of transactions.
Among features of the system are the following groups:
- Creation and management of custom complex assets, such as currency or indivisible rights, serial numbers, patents, etc.
- Management of user accounts
- Taxonomy of accounts based on domains — or sub-ledgers in the system
- The system of rights and verification of user permissions for the execution of transactions and queries in the system
- Validation of business rules for transactions and queries in the system
Among the non-functional requirements can be noted a high degree of network fault tolerance (Byzantine Fault Tolerant).
Iroha v0.95 preview version is released on [TBD].
System runs as a daemon, representing single peer in Iroha network. For each peer there is following package structure, corresponding to components of the system:
 |
- Torii (gate) is a package that contains classes, which are in charge of interaction with users (clients)
- Network encompasses interaction in network of peers
- Validation classes check business rules and validity (right format) of transactions or queries
- Synchronizer helps to sync newcomer peers or temporary disconnected peers
- Simulator generates temporary snapshot of storage to validate transactions
- Ametsuchi is ledger block storage
- Model classes are system entities, and converters for them
For other components and more explanation please take a look at technical and design docs.
You may use docker ennvironment to build and run the system. Execute the following:
git clone https://github.com/hyperledger/iroha.git
sh iroha/docker/run-ametsuchi-dev.sh
After that, container will run in interactive mode. So, you can run any IDE or editor on your local environment, while building the system in docker environment
To build the system, execute the the following:
cmake -H. -Bbuild; cmake --build build -- -j4;
Consider executing git clean -ix and choosing c option when you want to rebuild the system (to clean up generated protobuf code).
Also, use --clean-first flag for rebuild.
