Iroha 3

Iroha 3 is the Nexus-oriented deployment track shipped from the main Hyperledger Iroha workspace. It keeps the same core building blocks as Iroha 2 while adding the Nexus model for data spaces, multi-lane execution, and SORA-specific deployment profiles.

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 operator telemetry and status endpoints
