The mainnet upgrade replaces the Mysticeti engine with a DAG-based consensus model built for global trade reliabilityIOTA just shipped one of its most consequential upgrades to date. The Starfish consensus engine is now live on the IOTA mainnet, replacing the previous Mysticeti engine with a fundamentally different approach to how the network reaches agreement on transactions. It’s a structural overhaul designed to make IOTA the kind of infrastructure that global trade systems can actually depend on, even when network conditions get messy. Outbound recovery requests on the mainnet have decreased by approximately 10 times compared to the Mysticeti engine. The Starfish upgrade was specifically designed with this application in mind.
