Iroha is a straightforward distributed ledger technology (DLT), inspired by Japanese Kaizen principle — eliminate excessiveness (muri). Iroha has essential functionality for your asset, information and identity management needs, at the same time being an efficient and trustworthy byzantine fault-tolerant tool for your enterprise needs.
Check the overview page of our documentation. Here is a YouTube channel where we upload meetings and explanatory videos - check them out!
Iroha has the following features:
- Creation and management of custom fungible assets, such as currencies, kilos of gold, etc.
- Management of user accounts
- Taxonomy of accounts based on domains 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
- Multisignature transactions
Iroha is Byzantine Fault Tolerant and has its own consensus algorithm - YAC
A consensus algorithm is a process in computer science used to achieve agreement on a single data value among distributed processes or systems. Consensus algorithms are designed to achieve reliability in a network involving multiple unreliable nodes. Solving that issue – known as the consensus problem – is important in distributed computing and multi-agent systems.
Consensus, as an algorithm
An algorithm to achieve agreement on a block among peers in the network. By having it in the system, reliability is increased.
Consensus, as a component
Preserves consistent state among the peers within a peer network. Iroha uses own consensus algorithm called Yet Another Consensus (aka YAC). Distinctive features of this algorithm are its scalability, performance, and Byzantine fault tolerance. If there are missing blocks, they will be downloaded from another peer via Synchronizer. Committed blocks are stored in Ametsuchi block storage.
