Iroha 3

Iroha 3 is the first-release Hyperledger Iroha platform. It supports self-hosted networks and the multi-dataspace SORA Nexus deployment model from one deterministic codebase.

At a high level, Iroha 3 combines:

• deterministic execution and storage
• the Iroha Virtual Machine (IVM) for portable smart contracts
• Norito as the canonical wire format
• Torii for client, operator, and app-facing APIs
• Sumeragi consensus with mandatory data availability and reliable broadcast
• domainless canonical accounts with separately bound human-readable aliases
