2.0.0 (MVP) requirements

Goals

Hyperledger Iroha v2 aims to be an even more simple, highly performant distributed ledger platform than Iroha v1. V2 carries on the tradition of putting on emphasis on having a library of pre-defined smart contracts in the core, so that developers do not have to write their own code to perform many tasks related to digital identity and asset management.

Background and strategic fit

https://github.com/hyperledger/iroha/blob/iroha2-dev/iroha_2_whitepaper.md#11-relationship-to-hyperledger-fabric-hyperledger-sawtooth-hyperledger-besu-and-others

Assumptions

• Users will work with provided client libraries (iOS, Android, JS).
• 3f+1 nodes enough to tolerate f Byzantine nodes in the network.
• Iroha uses a simple data model made up of domains, peers, accounts, assets, signatories, and permissions, as shown in the figure below - all other entities are build on top of these set.

Requirements

Functional

Peer to Peer Network

Blocks Storage

Non Functional

Target Platforms

Iroha deployment should support GNU/Linux, MacOS and Windows machines with x86 and Arm64 CPUs.

Transactions Processing

Iroha Peer should be able to process 20,000 transactions per second.

Blocks Processing

Iroha should be able to commit a new block every 3 seconds.
