IRIS Network has officially announced on its X page that they are upgrading to Mainnet 4.0 on March 19, 2025, at approximately 06:00:00 UTC, at block height 29,186,000. The purpose of this upgrade is the introduction of a modular refactor. This modular refactor is meant to provide improved flexibility for developers as well as align IRISnet with the latest innovations in the Cosmos system.
Modular Refractor and Cosmos-SDK v0.50.11-lsm, Key Features of 4.0 Upgrade
Modular refractor is a major key factor of IRISnet Mainnet 4.0 upgrade. Project teams will now be able to use these modules separately as required. They will not have to load all of IRISHub’s functionality thanks to the reorganisation of some of the self-developed capabilities. It will improve customization and reduce bloating while smoothing the process of team building on IRISnet.
Moreover, integration of the latest Cosmos version with included LSM (Liquid Stake Module) support will ensure the compatibility with broader Cosmos system with optimised performance and IBC (Inter-Blockchain Communications).
Upgrading Schdeule of IRISnet Mainnet 4.0
The on-chain upgrade proposal was submitted to validators/delegators on March 14, 2025. The execution date decided for the Mainnet upgrade is March 19, 2025, at block height 29186000. Whereas, the Nyancat testnet was activated on March 4, 2025, and is still live till the mainnet launch.
Mainnet has requested developers, validators, wallets, explorers, node operators, and exchanges to come forward to check node operation, governance proposals and modular features.
IRIS Network: An Internet of Blockchains
An inter-connected web of blockchains, the IRIS network aims to provide a technological framework for the development of decentralized enterprise applications. Since the IRIS network is an extension of the broader Cosmos network, any two networks within the IRIS network can communicate with each other using industry-standard IBC protocol. Additionally, IRIS has added an extra layer of semantic networks to open up new business possibilities and simultaneously increase diversity and scale in the Cosmos network. IRIS Services are designed to mediate the gap between the blockchain and traditional business application worlds. The mentioned upgrade has further enhanced its productability.
To sum up, the upgrade of IRIS Mainet 4.0 is very significant as it introduced modular refraction and alignment with the broader Cosmos network.
